Tool
Prompt library.
24 working prompts in six categories — written to be pasted, filled in and used, not admired. Copy any of them.
Writing
Explain it three ways
Explain [topic] three ways: (1) to a smart 12-year-old, (2) to a busy executive in 3 bullets, (3) as an analogy from everyday life. Keep each under 90 words.
Headline lab
Give me 15 headline options for this article: [paste]. Mix styles — direct, curiosity, number-led, question. Then rank your top 3 and say why each works.
Tone match
Here is a sample of my writing: [paste]. Now write [new piece] in exactly that voice — same sentence length, rhythm and vocabulary level. Do not sound like a generic AI.
Coding
Explain this code
Explain this code like I am a competent developer seeing it for the first time: what it does, the data flow, the three riskiest lines and why: [paste code]
Debug with discipline
This code fails with [error]. Before suggesting fixes, list the 3 most likely causes ranked by probability, and one test to confirm each. Then fix only the most likely one: [paste code]
Write the tests first
Write a test suite for this function before any implementation: cover the happy path, empty input, boundary values and one hostile input. Use [framework]: [paste function signature / spec]
Code review, senior mode
Review this diff like a senior engineer on a careful team: flag correctness bugs first, then security, then performance, then style. Be specific, cite line numbers, skip nitpicks: [paste diff]
Business
Meeting to decisions
Turn these meeting notes into: (1) decisions made, (2) action items with owners and dates, (3) open questions. If an owner or date is missing, flag it instead of inventing one: [paste notes]
Cold email that respects the reader
Write a cold email to a [role] at a [company type] about [offer]. Under 90 words, one concrete observation about their world, one clear ask, no hype words, no fake familiarity.
Price objection script
A customer says our price is too high. Give me 3 responses: one that holds the price with value framing, one that offers a smaller scope at a lower price, and one graceful exit that keeps the door open. Context: [product, price, customer type].
One-page plan
Turn this goal into a one-page plan: objective, 3 milestones with dates, owner for each, the top 3 risks and how we will know it is working. Goal: [goal]. Constraints: [budget, team, deadline].
Marketing
Hook harvest
Give me 20 opening hooks for a short video about [topic] for [audience]. Each under 9 words, spoken style, no clickbait lies. Then pick the 3 strongest and say why.
One idea, five posts
Turn this idea into 5 different social posts: one story-led, one data-led, one contrarian, one how-to, one question. Idea: [idea]. Platform: [platform]. Keep each under 60 words.
Landing page teardown
Critique this landing page copy like a conversion specialist: what is unclear in the first 5 seconds, where trust is missing, and the single change you would test first: [paste copy]
FAQ from objections
List the 10 questions a sceptical buyer would ask about [product] before paying. Answer each in under 40 words, honestly — including where the honest answer is a limitation.
Study
Feynman check
I will explain [topic] in my own words. Grade my explanation: what is right, what is fuzzy, what is wrong — then ask me one question that targets my weakest point. My explanation: [paste]
Flashcards that stick
Make 12 flashcards from this material: front is a question that forces recall (not recognition), back is a short answer plus a memory hook: [paste material]
Socratic tutor
Teach me [topic] by asking me one question at a time. Start from what a beginner knows. Never lecture for more than 3 sentences; let my answers steer the lesson.
Exam prediction
From this syllabus/notes, predict the 8 most likely exam questions and give model answers at the depth a top student would write: [paste notes]
Productivity
Inbox triage
Sort these messages into: reply today, reply this week, delegate, ignore. For each 'reply today' item, draft a reply under 40 words in a warm, direct tone: [paste messages]
Decision memo
Help me decide [decision]. List the options, the strongest argument for and against each, what I would need to believe for each to be right, and your recommendation with its biggest risk.
Week in review
From these notes on my week, write: what got done, what slipped and why, the one lesson, and my top 3 priorities for next week. Be honest, not flattering: [paste notes]
Summarise like a chief of staff
