AI prompt library: free ChatGPT prompts, Claude prompts and prompt templates for real work

Turn a vague task into a professional prompt

For when you know what you want but not how to ask for it.

ACT AS: a prompt design specialist.

TASK: I will describe a task in plain, everyday language. Turn it into a professional prompt.

MY TASK: [describe what you want to achieve]

HOW TO BUILD IT:
1. Define the role the AI should take and why that role fits better than another.
2. List the minimum context needed. If something is missing, ask me before you continue.
3. Specify the output format: structure, length and who will read it.
4. Add two or three constraints that prevent the usual mistakes in this kind of task.
5. Finish with a three-point checklist to review the result.

LIMITS: do not fill gaps with plausible data. Mark any figure, source or deadline I have not given you as pending validation.

FINAL FORMAT: deliver the prompt ready to copy, and under it a two-line note explaining which decisions you made and why.

Audit a prompt that is not working

For when the AI gives you something generic and you cannot tell what is missing.

ACT AS: a prompt reviewer with sound judgment.

PROMPT TO REVIEW:
[paste your prompt here]

OUTPUT IT GAVE ME:
[paste the answer that did not work]

WHAT I NEED FROM YOU:
1. State the main flaw of the prompt in one sentence.
2. Point out which of these is missing: role, context, specific task, format, constraints, quality criteria.
3. Rewrite the prompt, changing only what is necessary.
4. Explain what you expect to change in the answer with the new prompt.

LIMITS: do not add requirements I have not asked for. If the real problem is that the task is poorly defined, say so instead of polishing the prompt.

Build a reusable prompt template for your team

Turn a task you repeat every week into something anyone can use.

ACT AS: an operations lead who documents processes.

REPEATED TASK: [describe the task you do every week]
WHO WILL USE IT: [the person's profile, what they know and what they do not]

BUILD:
1. A prompt template with variables in square brackets, marking which ones are required.
2. A filled-in example with fictional but realistic data from our industry.
3. The three things the person must check before using the output.
4. A clear rule for when this template should NOT be used.

LIMITS: the template has to work for someone who does not have the context I have in my head. If that is not possible, tell me which context needs to be documented separately.

FINAL FORMAT: template, example, review checklist and usage limit. Nothing else.

Summarize a long Word document with Copilot

For reports and contracts you need to read and have no time for.

Copilot

Summarize this document for [reader: leadership, a client, the technical team].

SUMMARY STRUCTURE:
1. What the document decides or proposes, in two sentences.
2. The three points that would change a decision, with the page or section where each appears.
3. Figures, deadlines and specific commitments, exactly as they appear in the text.
4. What the document does NOT say and we would need to know.

RULES: use only what is in the document. Do not fill in with general knowledge. If a figure appears without a source in the text itself, mark it as unverified. Keep the exact wording in contractual or regulatory passages.

LENGTH: one page at most. Neutral tone.

Prepare for a meeting from an Outlook thread

Copilot reads the thread so you walk in with a clear position.

Copilot

Review this email thread and help me prepare for the meeting.

GIVE ME:
1. The real status of the matter in three sentences, separating what has been agreed from what is still open.
2. Who has committed to what, and by when, quoting the email where they say it.
3. The two points where there is disagreement or silence.
4. Five questions I should ask in the meeting, ordered by how much they change the outcome.
5. A draft agenda for a 30-minute meeting.

RULES: do not read intentions that are not written down. If something has been taken for granted without confirmation, put it in a separate list of assumptions.

FORMAT: short lists, no long paragraphs.

Analyze an Excel sheet without writing formulas

Describe the business question and let Copilot run the analysis.

Copilot

Analyze the data in this sheet and answer a business question.

QUESTION: [for example, which products dropped compared with last quarter, and by how much]

HOW I WANT THE ANALYSIS:
1. First tell me which columns you used and what you understood each one to mean. If any column is unclear, ask before you calculate.
2. Give the result with the figure and the change, in currency and as a percentage.
3. Point out the three cases that weigh most in that result.
4. Suggest a business hypothesis that would explain the pattern, clearly labeled as a hypothesis.
5. Tell me which data is missing from the sheet to confirm it.

RULES: do not invent rows or fill empty values. If there are blank cells or inconsistent formats, say so before giving the number.

Turn a document into a PowerPoint presentation

From a finished report to a slide outline you can defend.

Copilot

Turn this document into a presentation of [number] slides for [audience].

STRUCTURE RULES:
1. The first slide states the decision to be made, not the project title.
2. One idea per slide. Each title is a full sentence that states the conclusion, not the category.
3. Four bullet points per slide at most, one line each.
4. Every figure shown has its source in the speaker notes.
5. The last slide is the specific ask: what you need from this audience and by when.

CONTENT RULES: use only what is in the document. Anything that is not there goes on a final "to be confirmed" slide. Do not add charts the data does not support.

SPEAKER NOTES: two sentences per slide, written the way people speak.

CONTEXT: [industry, company size, what has already been tried]
AVAILABLE DATA: [what you have; also say what you do not have]

4. The scenario in which your recommendation is the wrong one.
5. What you would measure at 90 days to know whether it is working.

ACT AS: a manager with experience in difficult conversations.

SITUATION: [what happened, with observable facts and dates]
THE PERSON: [time in the role, what they do well, what has changed]

Analyze a file with ChatGPT without made-up answers

For when you upload a PDF or a spreadsheet and need to trust the result.

ChatGPT

I am going to upload a file. Before you analyze it, follow this order.

STEP 1: tell me what you received. Number of pages or sheets, what each section or column contains, and what you understood it to mean. If anything is unclear, ask before you continue.

STEP 2: wait for my confirmation.

STEP 3: answer this question using only the file: [your question]

RULES FOR THE ANSWER:
1. Every statement comes with the page, sheet or cell it comes from.
2. Anything that is not in the file goes in a separate section called "not in the document".
3. If a figure appears without a source inside the file itself, mark it as unverified.
4. Do not fill in with general knowledge or with what is typical in the industry.

FORMAT: direct answer first, then the detail with references, and finally what is missing.

Turn a long conversation into an actionable summary

For ChatGPT threads that got out of hand.

WHO WILL READ IT: [profile and level of knowledge]

REVIEW IN THIS ORDER:
1. The central argument: state it in one sentence, using the document's words. If you cannot find it, that is the first finding.
2. The three points where the argument does not hold up with what the document itself provides.
3. Claims that need a source and do not have one, quoting where they are.
4. What is surplus: sections that could be removed without losing anything.
5. What is missing for the reader I described.
6. Internal contradictions, if any, with the two conflicting passages side by side.

LIMITS: do not rewrite anything yet. Do not soften the findings. If the document is good, say so and do not invent problems to justify the review.

Claude

ACT AS: a writer working with a strict style guide.

STYLE GUIDE: [paste the full guide, with its rules and examples]
EXAMPLES OF OUR TEXTS THAT WORK: [paste two or three]

TASK: [what needs to be written, for which channel and for whom]

BEFORE YOU WRITE:
1. Summarize in five points the rules in the guide that will most affect this text.
2. Say which two things make the examples I gave you recognizable.
3. Wait for my confirmation.

THEN: write the text and add, at the end, a list of the style decisions you made, with the rule from the guide that supports each one.

LIMITS: if the task conflicts with a rule in the guide, say so instead of resolving it yourself. Do not invent rules the guide does not contain.
