20 content ideas from one topic

When you're out of ideas and need fresh angles.

Rewrite text in a viral style

You have a dry, formal text and want it to get seen.

Interactive daily story sequence

Boost story engagement with polls and questions.

For a page in the [page niche] niche, design a 5-part story sequence that pulls the viewer in step by step: the first story opens with a question or poll, the middle stories deliver short valuable content, and the last story leads to [goal: DM / link / product]. Specify the text of each story and which interactive sticker to use.

Professional LinkedIn post

For personal branding and attracting opportunities.

Professional comment replies

Handle negative comments or repeated questions with the right tone.

You are the community manager of a [business type] page.

Replying to a negative review

Turn public criticism into a display of professionalism.

15 prompts

Explain a hard concept simply

When you've read the material but still don't get it.

Explain the concept of [concept name] from [course name] at three levels: first with an everyday-life example a teenager would understand, then at university level with the correct terminology, and finally the most common misconception students have about it. End by asking me a question to check that I actually understood.

Structured lecture-notes summary

Turn long notes into a night-before-exam review sheet.

Summarize the following text for exam review with this structure: key concepts (each with a one-line definition), important formulas or rules, the relationships between concepts in a simple text diagram, and three points most likely to appear on the exam. Add nothing of your own — use only the text, and flag anything ambiguous. Text: [lecture notes]

Build a quiz from my notes

Test yourself before your professor does.

Build a quiz from the following text: 5 multiple-choice questions (with plausible distractors), 3 short-answer questions and 2 analytical questions that combine several concepts. First give only the questions and wait for my answers; after I answer, reveal the correct answers and explain my mistakes. Text: [study notes]

Study plan until exam day

A realistic plan based on your actual free time.

[number of days] days remain until my [course name] exam and I realistically have [hours] hours per day. Chapters: [chapter list]. My weak spot: [hardest topic].

Flashcards for spaced review

Memorize with the science of spaced repetition.

Create 20 flashcards from the following text. Card format: "Front: a short, precise question | Back: an answer of at most two lines".

Learn with the Feynman technique

The strongest deep-understanding technique — AI becomes your student.

I want to learn [concept name] using the Feynman technique. Play the role of a curious student: I will explain the concept to you, and wherever my explanation is vague, incomplete or wrong, ask simple but precise questions and don't let it slide. At the end, list the weak points in my understanding. Start now: ask me to explain.

Academic paper outline

Build the skeleton before you write.

For a paper on [research topic] in the field of [field], propose a complete structure: a suggested title, the problem statement in three sentences, research questions, section headings with a one-line description of each section's content, and an appropriate research method. Suggest three English keywords for finding credible sources. Do not write the paper — structure only.

Critique and improve my writing

Instead of AI writing for you, make it strengthen your writing.

I wrote this text myself: [your text]. Do not rewrite it. Critique it like a strict but fair professor: three strengths, three main weaknesses (argument, structure, evidence) with exact examples from my text, and for each weakness tell me how to fix it myself. Finally give a score out of 20 and say what would raise it one notch.

Compare confusable concepts

Untangle concepts you always mix up — once and for all.

I keep confusing these concepts: [concept 1, concept 2, concept 3]. Build a comparison table with: a one-line definition, the key difference, one tangible example for each, and where each one is used. End with a simple sentence or mental image that will make sure I never mix them up again.

Step-by-step help without spoiling the answer

Actually learn problem-solving instead of copying solutions.

Here is my problem: [problem statement]. Do not give the final answer directly. Act as a private tutor: first ask how far I've gotten, then use small hints and guiding questions to help me find the next step myself. Only if I get stuck twice in a row, explain that one step fully — then hand the lead back to me.

Skill-learning roadmap

From "I'd love to learn it" to a concrete weekly plan.

I want to learn [skill name] starting from [beginner / intermediate] level, with [hours] hours per week. My goal: [end goal].

Also warn me about the three most common beginner mistakes on this path.

Understand a research paper

Read scientific papers without drowning in jargon.

This is a section of a research paper: [paper text]. Give me three outputs: a fluent one-paragraph plain-language summary (not sentence-by-sentence paraphrase), a list of the technical terms with short explanations, and one sentence stating the core finding in a way I could present in class. If the text uses a particular statistical method, explain in simple words what it does.

Beat study procrastination

When you know you should study but can't start.

I need to do [assignment or subject] but keep putting it off. The likely reason: [too big / too hard / boring / fear of doing badly].

Also give me a short explanation of why this method works on a procrastinating brain.

Class presentation prep

A presentation that keeps the class awake and satisfies the professor.

I have to give a [duration]-minute presentation on [topic]. Structure it for me: a compelling 30-second opening, 3 main sections each with its key message, and a memorable wrap-up. For each section give a slide title and 3 short bullets. Also prepare the five questions the professor is most likely to ask, with brief answers.

Choosing a thesis topic

A topic that is both defensible and finishable.

I'm a [degree level and field] student interested in these areas: [areas of interest]. My resources: [access to data / lab / study population].

For writers, translators and anyone who works with text — editing, natural translation, tone changes and creative writing.

15 prompts

Three-layer professional edit

Full editing without losing the writer's voice.

Act as a professional editor and edit the following text in three layers: mechanical (spelling, punctuation), language (long sentences, repetition, awkward constructions) and structural (logical order of paragraphs). Preserve the writer's style and voice. Give the edited text, then a list of the most important changes with the reason for each. Text: [your text]

Natural translation, not literal

A translation that doesn't smell like a translation.

Translate this text from [source language] to [target language] so it reads as if originally written in the target language: restructure sentences natively (not word by word), replace idioms with common target-language equivalents, and use a [formal / conversational / journalistic] tone. Wherever you made a judgment call, list it at the end with a one-line explanation. Text: [text]

Change the tone of a text

One text, several tones — for different audiences.

Rewrite this text in three tones while fully preserving the meaning: formal (for official correspondence), friendly and conversational (for social media), and neutral and fluent (for a website). Each version must feel natural — not just a few swapped words. Text: [your text]

Break up long sentences

Make breathless text readable and rhythmic.

The following text is full of long, nested sentences. Rewrite it: each sentence should carry one idea, average sentence length under 15 words, but not monotonous — build rhythm by mixing short and medium sentences. Cut filler words and redundancy. Text: [your text]

Strong article openings

A first paragraph that keeps the reader.

Each at most 60 words. Then tell me which one is strongest for this topic and why.

Headline generation

A headline that earns the click and keeps the text's credibility.

For an article with this content: [one-line article summary], suggest ten headlines in different groups: two questions, two numbered/list style, two how-to, two counterintuitive and two direct/newsy. All under 60 characters, no dishonest exaggeration. If I provided the keyword [SEO keyword], weave it naturally into half of them.

Short story from one idea

For creative writing practice or narrative content.

Write a 500-word short story with these elements: central idea [idea or situation], main character [short character description], and setting [time and place]. Rules: start in the middle of the action, show emotions instead of telling them, use natural dialogue, and let the ending change something — even something small. No explicit moral at the end.

Fix a machine-translated text

Rescue text that was translated badly.

This text came from a rushed or machine translation and its structure still feels foreign. Make it fully native: find and fix calques and unnatural constructions, restore the natural word order of the language, and replace awkward vocabulary with established equivalents. Also give a separate list of the calques you found. Text: [text]

Professional email in English

For writing to a foreign company, professor or international client.

Write a professional English email. Goal: [email goal]. Recipient: [recipient's role]. Points I need to make: [points].

Speech for an occasion

For a celebration, introduction, thank-you — any microphone they hand you.

Write a [duration]-minute speech for [type of event]. My role: [my relation to the event]. The text must be written for speaking, not reading: short sentences, marked pauses, one mild and safe joke, and one genuinely emotional moment.

Actionable book summary

Get practical output from a book you've read.

I've read [book title and author]. Help me consolidate it: the book's central message in one paragraph, five key ideas each with a two-line explanation, and most importantly: three concrete actions I can implement starting this week in [area of my life/work]. If the book has serious criticisms, state them honestly.

Find the exact right word

When the word is on the tip of your tongue but won't come.

I'm looking for a word or expression that conveys this feeling or situation: [description of the feeling or situation]. Suggest ten options ranging from formal to colloquial, write one example sentence for each so the subtle differences are clear, and tell me in which context each one sounds most natural.

Feedback on creative writing

Serious literary criticism, not polite compliments.

I wrote this literary piece/poem: [text]. Critique it like a serious but caring literary critic: where is the strongest image or line and why does it work, where does the language fall into cliché, where does the rhythm falter, and which cut would make the text stronger. Do not rewrite — just show me where to rewrite myself.

Simplify technical writing

Make technical text understandable for a general audience.

Rewrite this technical text for a general audience: either remove every technical term or immediately explain it with an everyday analogy, shorten the sentences, and do not sacrifice accuracy for simplicity — if a simplification changes the meaning anywhere, flag it right there. Final audience: [audience]. Text: [technical text]

Personal congratulation message

A greeting that doesn't feel copy-pasted.

Write a [occasion] congratulation message for [recipient and my relationship to them] that feels personal and real: it should reference a shared trait or memory ([personal detail]), avoid recycled greeting-card lines, and match the length to the relationship.

Then fix the most likely one and explain why the bug happened.

Code review

A senior reviewer checking your code before it ships.

As a senior developer, review this code: [code]. Comment on four axes: potential bugs and edge cases, security issues, readability and naming, and performance. For each finding give the line number and a concrete fix. Prioritize: which items are critical and which are stylistic. Do not rewrite the whole file.

Explain unfamiliar code

Understand legacy code or other people's code fast.

Explain this code to me: [code]. First say in one paragraph what the whole thing does, then walk through it section by section in plain language, and finally: point out any non-obvious tricks I might miss, and mention any obvious improvement opportunities. My level: [beginner / intermediate / advanced] — calibrate the depth to that.

Architecture before coding

Map first, code second — avoid the rewrite.

I want to build this project: [project description and features]. My available/preferred stack: [stack]. Don't write code yet.

Put the three most important architecture decisions in front of me with options and trade-offs for each.

Refactor messy code

Code that works but is a nightmare to maintain.

This code works but has become hard to maintain: [code]. Refactor it under these principles: external behavior must not change at all, long functions break into single-responsibility units, names become self-explanatory and duplication is removed. Output: the refactored code + a before/after table of the important changes + if a test is needed to guarantee unchanged behavior, propose it.

Write tests for my code

Real coverage, including the cases you forget.

Write tests for this code: [code] using [test framework]. Cover: the happy path, edge cases (empty input, boundary values, null), and error paths. Every test needs a descriptive name that reveals what it checks without reading the body. Finally, tell me which scenarios remain uncovered and whether the code itself needs changes for testability.

Translate code between languages

Migrate code without losing language subtleties.

Convert this [source language] code to [target language]: [code]. Don't translate literally — use the idiomatic patterns of the target language.

Optimize a slow database query

Fix the slow query before buying a bigger server.

This query is slow: [query] — Table structure: [tables and current indexes] — Approximate data volume: [row counts].

If the real problem is the table design, say so honestly.

Regex with explanation

A regular expression you'll still understand in six months.

Write a regular expression that: [pattern description]. It must match these samples: [valid samples] and reject these: [invalid samples]. Language/engine: [language].

Learning path for a new language

Learn faster by leaning on what you already know.

I'm a [languages I know] programmer and want to learn [new language] for [goal: web, mobile, data, etc.]. Build a learning path that shortcuts through my existing knowledge: concepts that are the same and only need new syntax (skim fast), concepts that are thought about differently in the new language (main focus), and three practice projects with escalating difficulty. Also warn me which habits from my old language count as anti-patterns here.

Documentation and README

Docs people actually read and use.

Write a complete README for this project: [project description or main code]. Structure: one sentence on what the project does and who it's for, step-by-step install and setup (with prerequisites), a real usage example with output, the important configuration options, and common troubleshooting. Assume the reader is in a hurry: most important things first, every command copy-pasteable.

Commit message and PR description

A git history your team (and future you) will thank you for.

I made these code changes: [change description or diff]. Write for me: a standard commit message (first line under 50 characters with an imperative verb, body explaining the "why" not the "what"), and a Pull Request description covering: summary of the change, motivation, how it was tested, and what the reviewer should pay attention to. If the changes should be split into independent commits, propose the split.

Web security review

Break your own code before the hackers do.

This code is part of a web application: [code]. Review it with a security lens focused on: injection (SQL/command), XSS, input validation, session and authentication handling, and information leakage in errors. For each vulnerability: the exact location, an abuse scenario in plain words, and the fixed code. Prioritize by severity (critical/medium/low).

Choosing the right tech stack

A stack decision without hype or bias.

For a project with these specs: [project type, scale, users], a team with these skills: [team skills] and these constraints: [budget, timeline, hosting] — compare the options [candidate options]. Criteria: development speed, maintenance cost, ecosystem and hiring pool, and long-term risk. Give one clear final recommendation and state under what conditions your recommendation would flip.

A habit that survives past week two.

I want to build the habit of [desired habit]. I've failed before: [past attempts and why they failed]. Design a plan based on the science of habit formation: a two-minute starter version of the habit, stacking it onto an existing habit, environment design, and an if-then plan for low-motivation days. Set the first week's success bar deliberately low and explain why.

Monthly budget management

See where your money actually goes.

My monthly income is [amount] and my fixed expenses are: [fixed expense list]. My goal: [saving for X / cutting spending]. Design a simple, executable budget structure: expense categories with a suggested cap for each, the three places I'm probably leaking money and should examine, and a tracking method that takes under 5 minutes a week. No generic advice — base everything on my numbers.

Job interview preparation

Practice with a tough virtual interviewer.

I'm preparing for a [job title] interview at a [company type]. My background: [background summary]. Play the interviewer: ask questions one at a time (technical and behavioral), give me short feedback after each answer — what was good, what a real interviewer would read negatively — then move to the next question. Use some pressure questions too, so I build real readiness. Begin.

Untangle an overwhelming day

When everything is "urgent" and you don't know where to start.

My head is a mess; all of this is piled on me: [all tasks and worries, unsorted]. Sort it out: classify with the urgent/important matrix, identify the three things that truly must happen today, separate what can be deleted or delegated, and for the first task, give me only the very first step so I can start right now. Answer short and decisive — no motivational speech.

Resume from raw experience

Turn scattered experience into a convincing resume.

I'm writing a resume for the position of [target job]. Here's my experience and skills, raw and unpolished: [free-form background]. Turn them into professional resume bullets: each bullet starts with a strong verb, includes a measurable result where possible (if I have no numbers, ask me questions to find them together), and aligns with the target role's needs. Invent nothing — just tell my real story powerfully.

Preparing a difficult conversation

Organize your words before a sensitive conversation.

I need to have a difficult conversation with [the person and our relationship] about [topic]. My worry: [fear of conflict/misunderstanding]. Help me prepare: phrase my core request in one blame-free sentence, suggest three calm opening lines, walk through their most likely reactions and the right response to each, and define the red line — and how to end the conversation respectfully if it's crossed.

Language practice by immersion

Turn AI into your language conversation partner.

I'm learning [language] at [level] level. Talk with me only in that language about [favorite topic], with these rules: match the vocabulary to my level; when I make a mistake, let me finish first, then briefly show the correct form; and every few messages, introduce one useful new expression and let me infer its meaning from context. Start with a simple question.

Thoughtful gift ideas

A gift that shows you actually thought about it.

I need a gift for [recipient and my relationship] for [occasion] with a budget of [budget]. What I know about them: [interests, lifestyle, things they mentioned recently]. Suggest ten gift ideas in three groups: practical, experience-based (instead of an object), and emotional/personalized. For each, one line on why it fits this specific person. Skip clichés (perfume, watch, chocolate) unless with a special twist.

Plain-language contract analysis

Understand what you're signing — before you sign.

Analyze this contract / terms of service in plain language for me: [contract text]. Tell me: my main obligations, the other party's obligations, which clauses weigh against me or are ambiguous and why, and what questions I should ask before signing. Emphasize that this analysis is no substitute for professional legal advice and that important matters need a lawyer.

Organize your digital life

Declutter your phone and laptop once and for all.

My digital space is chaos: [situation: too many photos, scattered files, notifications]. Give me a staged clean-up plan where each stage takes at most 30 minutes: a simple, durable folder structure, a file-naming rule, which notifications to silence, and a 10-minute weekly routine that keeps it from getting messy again. Avoid complex systems that create their own overhead.

How to get the best results from these prompts

Four simple steps that multiply the quality of AI answers.

1

Copy the prompt

Hit the Copy button on any card and paste the text into ChatGPT, Claude, Gemini or any other AI.

2

Fill in the blanks

Replace the bracketed parts like [topic] with your real details — the more specific, the better.

3

Add your context

If the answer feels generic, give more details about your situation. AI gets sharper with your specifics, not with repeated questions.

4

Ask for revisions

The first output is a draft. Say "make it shorter", "make the tone friendlier" or "give three more versions" until it's right.

Frequently asked questions

Everything you should know before you start.

What is a prompt and why does it matter?+
A prompt is the text you give an AI to get something done. The quality of the AI's answer depends directly on the quality of your prompt: a precise prompt with a clear role, goal and output format produces dramatically better results.
Which AI models do these prompts work with?+
Every prompt in this library works with ChatGPT, Claude, Gemini, Copilot and virtually any other language model, because they are built on universal prompt-writing principles: role, context, task and output format.
What do I do with the parts in brackets like [topic]?+
Brackets mark the blanks in each prompt. After copying, replace every bracketed phrase with your own details — for example, replace [product name] with your actual product. The more specific your details, the better the answer.
Are these prompts free to use?+
Yes. All 90 prompts in this library are completely free with no sign-up required. Just click Copy and paste the prompt into your AI tool of choice.
How can I learn professional prompt writing?+
Start with the AI articles in the Filtor magazine, which explain how to build effective prompts step by step. Practicing with these ready-made prompts and tweaking their parts is also the best hands-on way to learn.
