Long Document Analyzer
Intermediate
Get a structured, critical read of a long document in one pass.
Prompt
I will paste a long document below. Analyze it and return: (1) a 2-3 sentence executive summary, (2) the main argument or purpose, (3) 5 key points in order of importance, (4) any claims that seem unsupported or would benefit from a source, and (5) 3 questions a critical reader might raise. Stay grounded in the text and clearly separate what the document says from your own analysis. Document: [PASTE DOCUMENT].
Best for

Example usage
A 10-page strategy memo returns an executive summary, its core thesis, ranked points, and two claims flagged as needing data.
Constructive Writing Critique
Beginner
Receive balanced, specific feedback on a draft without losing your voice.
Prompt
Act as a thoughtful writing coach. Review the following draft for clarity, structure, and tone. Give feedback in three parts: what works well, what to improve, and a short prioritized list of specific edits. Be honest but encouraging, quote brief snippets when pointing to issues, and do not rewrite the whole piece. Draft: [PASTE DRAFT].

Claude, ChatGPT
Example usage
On a blog intro it praises a strong hook, flags a buried main point, and lists three line-level edits to tighten it.
Compare Two Options Objectively
Intermediate
Compare two options fairly across priorities, with trade-offs made explicit.
Prompt
Act as a neutral analyst. Compare [OPTION A] and [OPTION B] for someone whose priorities are [LIST PRIORITIES]. Present a side-by-side comparison table across the criteria that matter most, then write a short, balanced verdict for two different reader types. Be explicit about trade-offs and avoid hype. If a fair comparison needs information I have not provided, list what is missing.

Claude, Gemini
Example usage
Comparing two project tools for a small team yields a feature table and separate verdicts for budget-focused and feature-focused buyers.
Reasoning Sanity Check
Advanced
Stress-test the logic of an argument or plan before you commit to it.
Prompt
I am going to share an argument or plan. Act as a careful, fair critic. Identify the key assumptions it relies on, point out any logical gaps or weak links, and note where it might be right. Do not be contrarian for its own sake. End with the single change that would most strengthen the argument. Here it is: [PASTE ARGUMENT OR PLAN].
Best for
Claude
Example usage
For a launch plan it surfaces an unstated assumption about demand and suggests validating with a small pre-sale first.
Structured Long-Form Outline
Intermediate
Build a thorough, logically sequenced outline for a long article or guide.
Prompt
Act as a content strategist. Create a detailed outline for a long-form piece on [TOPIC] aimed at [AUDIENCE]. The angle is [ANGLE]. Provide a working title, a one-paragraph thesis, and a full H2/H3 structure with a sentence under each section describing what it covers. Note where examples, data, or visuals would add the most value. Keep the structure logical and avoid repeating sections.
Best for

Multi-Constraint Instruction Follower

Prompt
Complete the following task while strictly observing every constraint. Task: [DESCRIBE TASK]. Constraints: [LIST ALL CONSTRAINTS, e.g. exactly 5 items, no more than 12 words each, formal tone, no exclamation marks]. After your answer, add a short checklist confirming you met each constraint, marking any you could not satisfy and why.
Best for
