Best Claude prompts for makers and PMs

Thirty prompts that actually produce usable output — organized by the tasks that eat most of a product person's week — plus the three techniques that explain why the same prompt works for some people and fails for others.

Quick answer
The best Claude prompts share a structure: context first, one clear task, a named output format, and a quality bar ("flag any assumption you're making"). The prompts below are organized by workflow — PRDs, user research, competitive analysis, stakeholder updates, and launch — with the verbatim phrasing you can copy and edit.

Why most Claude prompts underperform

The standard failure mode: you send Claude a vague request, it returns prose that sounds authoritative and applies to any product. You spend twenty minutes editing generic output into something specific. It's faster than starting from scratch, but not by much.

The gap is almost never the model. Claude 3.5 Sonnet and Claude 4 are capable of producing genuine first drafts — the kind you can send to a stakeholder without a rewrite pass. The gap is that Claude has no idea what you're working on. It knows nothing about your users, your competitive landscape, or the decision you're actually trying to make. Without that context, it fills the space with plausible generalities.

Three things fix it, and they apply to every prompt in this guide:

  1. Context before task. A sentence or two about your product, your users, and what you're trying to decide is worth more than any prompt engineering trick. "We're building a project management tool for three-person freelance studios, not enterprises" changes every answer Claude gives you.

  2. One action verb per prompt. Write, analyze, rewrite, compare, synthesize — not a chain of all five. Compound prompts get compound answers: superficial on every part, deep on none.

  3. Ask for pushback. Ending any important prompt with "Flag any weak assumptions in what I'm asking" turns Claude from a validator into a sparring partner. This is the most underused technique in every guide that covers Claude prompts.

PRD and feature spec prompts

Product requirements documents are where most PMs start with Claude, and where generic output hurts most. A PRD Claude invents from thin air contains no real constraints, no actual edge cases, no trade-offs your team cares about. It reads like a PRD, but it's useless.

Prompt 1 — First draft PRD from a brief

Here is a one-line brief for a feature: [brief].

My product: [one sentence on what it does and who it's for].
Our biggest constraint: [engineering bandwidth / regulatory / performance / etc.].

Write a PRD that includes: problem statement, success metrics (3 max), proposed solution, out of scope, open questions. Format as a structured document I can share with engineers.

Flag any assumption you're making about user behavior or technical feasibility.

Prompt 2 — User stories from a PRD section

Here is the proposed solution section from a PRD: [paste].

Write user stories in "As a [persona], I want [action], so that [outcome]" format. Each story needs at least two acceptance criteria written as testable "Given / When / Then" conditions. Persona options: [list your actual personas].

Reject any story that would require a separate PRD to spec properly — break those out as a list at the end.

Prompt 3 — Technical feasibility questions

Here is a PRD for [feature name]: [paste].

Write a list of questions an engineering lead would ask before committing to a timeline. Organize by category: data model, third-party dependencies, edge cases, performance, rollback. No answers — questions only.

Prompt 4 — PRD critique

Here is a PRD draft: [paste].

Play the role of a skeptical senior PM who has shipped this category of product before. Give me your three biggest concerns — not general PRD quality issues, but specific gaps given what I've written. Quote the section you're responding to.

User research prompts

Claude is genuinely strong at synthesis work — reading a stack of user interview transcripts and extracting patterns is a task it does well, once you give it the actual transcripts.

Prompt 5 — Interview transcript synthesis

Here are five user interview transcripts: [paste].

Synthesize them into: (1) three to five distinct pain points with direct quotes supporting each, (2) one insight that surprised you — something that didn't match a conventional assumption about this user, (3) the one question these interviews left open.

Do not make up quotes. If a theme appears in fewer than two interviews, say so.

Prompt 6 — Survey open-text analysis

Here are 40 open-text responses to the question "[your survey question]": [paste].

Cluster the responses into no more than six themes. For each theme: a label (3 words max), a representative verbatim quote, and an approximate percentage of responses. List any responses that didn't fit a cluster.

Prompt 7 — Research synthesis into personas

Here is a summary of our user research findings: [paste].

Write two to three user personas. For each: a name and role, their primary goal when using [your product], their biggest frustration with current tools, and a verbatim-style quote that captures their mindset. Base these strictly on the research provided — don't add archetypal PM/designer personas unless the research mentions them.

Prompt 8 — Interview guide

We're running discovery interviews to understand [problem area] among [user type].

Write a 45-minute interview guide. Include: an opener that builds rapport and explains the session is about their experience, not a product test; five to seven core questions that elicit stories rather than opinions; two probes per question to go deeper. Avoid any question that could be answered yes or no.

Competitive analysis prompts

Generic competitive analysis from Claude is thin because Claude's knowledge of specific products has a cutoff and it doesn't know your positioning. Give it the raw material.

Prompt 9 — Feature comparison

Here is a structured comparison of four competitors: [paste your notes or feature matrix].

Identify: (1) the one axis where we are genuinely ahead, (2) the one axis where a named competitor is genuinely ahead of us and customers care about it, (3) the whitespace — a segment or use case none of them serve well. Be honest about #2; I need this for internal strategy, not sales copy.

Prompt 10 — Positioning draft

Our product: [one sentence].
Our three strongest competitors: [names + one sentence each].
What we do better: [specific].
What we lose on: [honest].

Write three positioning statement options, each targeting a different buyer emotion: one for the person burned by the incumbent, one for the person evaluating rationally, one for the person who needs to justify the switch to a team. Each should be under 30 words.

Prompt 11 — SWOT

Here is a raw set of facts about our product and market: [paste].

Write a SWOT analysis. Each quadrant: four items, ranked by importance. For every Weakness, write one mitigation we could realistically attempt. Do not include generic items like "strong team" or "growing market" unless the evidence above supports it specifically.

Stakeholder communication prompts

Writing for stakeholders is where Claude's ability to hold tone and structure pays off. The trick is telling it who the reader is and what decision they need to make.

Prompt 12 — Executive summary of a long doc

Here is a [PRD / research report / strategy doc]: [paste].

Write a four-paragraph executive summary for a VP who will spend two minutes reading this. Paragraph one: what we decided and why. Paragraph two: what we're not doing and why not. Paragraph three: what we need from them. Paragraph four: risks and how we're handling them.

Prompt 13 — Status update

Here is a raw brain dump of where the [project name] project stands this week: [paste notes].

Rewrite this as a status update for a weekly all-hands. Format: one sentence summary (green / yellow / red), three bullet points on what happened, one bullet on the main risk, one bullet on what we need from other teams. Total under 150 words.

Prompt 14 — Slide narrative outline

I need to present [topic] to [audience: board / investors / eng team / cross-functional].

The decision I want them to make by the end: [specific decision].

Write a ten-slide narrative outline — not bullet points on each slide, but the *story* the deck tells, one sentence per slide. Then write the three strongest objections this audience is likely to raise and a one-sentence response to each.

Prompt 15 — Difficult message to a stakeholder

I need to tell [stakeholder role] that [the bad news].

Context: [what happened, what led to it, what we've already tried].

Write a message that: leads with the impact, not the backstory; owns what went wrong without hedging; states clearly what happens next. Under 200 words. Don't soften the central fact.

Launch and go-to-market prompts

Prompt 16 — Launch announcement (internal)

We are launching [feature name] on [date]. It does [one sentence on what it does]. The users who will care most: [segment]. The risk of the launch: [specific].

Write an internal launch email for the company. Tone: direct, not celebratory. Include: what it is, who it's for, what to watch in the first week, and the one thing we're most worried about.

Prompt 17 — Launch announcement (external / changelog)

Feature: [name and what it does].
Who it's for: [user type].
The problem it solves: [specific].
One concrete thing users can do now that they couldn't before: [specific].

Write a changelog entry under 100 words. No adjectives that don't add information. No "we're excited to announce."

Prompt 18 — Launch checklist

We are launching [feature] to [audience] on [date]. Our product is [description]. Our stack involves: [relevant tech].

Write a launch checklist organized into: T-7 days, T-2 days, day of, T+3 days. Include the categories most relevant to a product launch in a [B2B SaaS / consumer / developer tool / etc.] context. Flag any item that is easy to forget but high-consequence.

Prompts for makers (builders, indie hackers, solo founders)

Prompt 19 — Landing page copy

Product: [name and one sentence on what it does].
Primary user: [who, their role/situation].
The main alternative they use today: [competitor or workaround].
The thing we do that they can't: [specific].

Write a landing page hero section: headline (under 10 words), subhead (under 25 words), three value proposition bullets (each under 12 words). Avoid "streamline," "seamless," "powerful," and any phrase that would also apply to a spreadsheet.

Prompt 20 — Cold email

I'm reaching out to [recipient type] about [product]. They don't know me.

The one thing I want them to do after reading this: [specific action].
What's in it for them, specifically: [concrete benefit, not a feature list].

Write a cold email under 80 words. Lead with something relevant to them, not to me. No "I hope this finds you well." No product feature list. One CTA.

Prompt 21 — Pricing page copy

Our pricing is: [tiers, prices, what's in each].
The most common objection at checkout: [what you've heard].
The user most likely to upgrade from free to paid: [describe them].

Write copy for a pricing page: a one-line pitch above the tiers, two to three words that label each tier (not "Basic / Pro / Enterprise"), and one sentence of social proof or risk-reduction copy below the CTA.

Prompt 22 — Rejection or churn email response

A user said: "[verbatim feedback or cancellation reason]."

Write a reply that: acknowledges their specific reason (not generic), offers one concrete thing we're doing or planning to address it if true, and keeps the door open without being needy. Under 100 words.

Prompts for working with Claude's own output

These are the prompts most people skip — asking Claude to critique and tighten what it already produced.

Prompt 23 — Cut 30% without losing meaning

Here is a draft: [paste].

Rewrite it at 70% of the word count. Prioritize cutting: throat-clearing openers, phrases that restate what was just said, any sentence that wouldn't be missed. Do not cut any specific fact, number, or decision. Show me the cuts you made as a diff if possible.

Prompt 24 — Tighten the argument

Here is an argument I'm making to [audience]: [paste].

Identify: (1) the one sentence that most undermines my credibility — the place where I'm overstating, hedging badly, or making a claim I haven't supported; (2) the counterargument I haven't addressed; (3) the sentence I could cut that would actually strengthen the point.

Prompt 25 — Plain language rewrite

Here is a technical explanation of [thing]: [paste].

Rewrite it for a non-technical reader who has never heard of [technical term]. No jargon, no acronyms without expansion. Target: a smart 16-year-old who cares about the problem but not the implementation. Under 150 words.

System prompt and project setup prompts

One of Claude's genuine edges over other models is that it follows long, structured system prompts faithfully. A well-written project system prompt turns every session into a context-loaded conversation rather than a cold start.

Prompt 26 — Product context system prompt

You are my PM assistant for [product name].

Product: [2–3 sentences on what it does, who it's for, and the core value proposition].
Users: [describe the primary user segment and their main job to be done].
Competitors: [list 2–3, with one sentence on what each is known for].
Our positioning: [where we win, where we concede].
My role: [your role and what you typically ask Claude to help with].
Tone: [direct, no hedging, flag when you're uncertain].

When I paste raw material (transcripts, data, notes), default to synthesis — pull out the signal and surface what's non-obvious. When I ask you to write, default to the format I describe or ask me before writing prose.

Prompt 27 — Iteration prompt (after a first draft)

Here's what you wrote: [paste Claude's output].
Here's what I actually need it to do differently: [specific].
Here's why the previous version missed: [specific].

Revise it with those constraints. Don't re-explain what you changed — just show me the new version.

Prompts for code and prototyping

Prompt 28 — Prototype brief

I want a working prototype of [feature]. It should: [list 3–4 core interactions].
Use: HTML, CSS, and JavaScript in a single self-contained file. No external dependencies except [CDN library if needed].
Do not build: [what to leave out to keep it scoped].
The prototype is for [stakeholder type] who will [what they'll do with it]. Optimize for clarity of the core interaction, not production quality.

Prompt 29 — Code review

Here is a [language] function that [what it does]: [paste code].

Review for: (1) the most likely runtime bug; (2) the edge case I probably haven't handled; (3) one thing that will make this hard to maintain in six months. Give me the line number and a one-sentence fix for each.

The prompt most people don't write

Prompt 30 — What am I missing?

This is the hardest one to write, and the most useful:

I'm about to [decision / action / launch / write]. Here is everything I know about the situation: [paste].

What am I not considering? Be specific — not general advice, but what is missing or wrong given exactly what I've described. Rank the gaps by how much they could change my decision.

Claude is genuinely good at this because it has no stake in your decision, no ego about the plan, and no incentive to tell you what you want to hear. Most people only use Claude to execute, not to stress-test. This prompt is the one that pays back most when you're about to make a mistake.

Sharing what Claude builds
When Claude produces a document, PRD, or prototype worth reviewing, the standard move is to screenshot it or copy it into Slack — and watch the feedback fragment across threads. Drafty is a way to publish it as a link (from Claude or any tool) where anyone can click the exact element and leave an anchored comment, no account. Your agent reads the comments and ships a revision to the same URL. One link from first draft to sign-off.

Claude prompts — frequently asked questions

How do you write a good Claude prompt?
Context first, one task, a named output format, and a quality bar. The single biggest improvement: add a sentence of context about your product and users before the task. Without it, Claude fills the space with plausible generalities. With it, the first draft is usually 80% of the way to usable.
What's different about prompting Claude vs ChatGPT?
Claude follows long, detailed instructions more faithfully — where ChatGPT starts to drift from constraint #5 or #6 in a multi-part prompt, Claude tends to honor all of them. Claude is also more willing to say "I'm not sure" rather than hallucinate a confident answer. The tradeoff: Claude can be more verbose by default and sometimes needs an explicit word-count or "be direct" instruction.
How long should a Claude prompt be?
Most effective prompts run 80–200 words. Beyond 300 words you're usually adding noise, not signal — Claude starts weighting early instructions over later ones. The exception: pasting raw material (transcripts, data, docs) that Claude needs to synthesize. That can be much longer; Claude's 200K context window handles it well.
Can you save prompts in Claude?
Not as a native prompt library. The closest thing: Claude Projects, which lets you add a system prompt that loads every session. Write your context prompt once (see Prompt 26 above), save it to a project, and every conversation in that project starts context-loaded. Some teams also keep a prompts doc outside Claude and paste as needed.
What is a system prompt in Claude?
A system prompt is an instruction set that loads before the conversation starts, setting Claude's behavior, tone, and context for the whole session. In Claude.ai, you add it via Project Instructions in a Project. Via the API, it's the system parameter. A good product system prompt means you never re-explain your product to Claude — it already knows.
What are the best Claude prompts for product managers?
The most consistently useful ones: PRD critique (Prompt 4 above), user interview synthesis (Prompt 5), and the what-am-I-missing prompt (Prompt 30). These three produce the most non-obvious output — Claude surfaces gaps, not just structure. Generic PRD and roadmap prompts exist everywhere; the value is in the critique and synthesis prompts that PMs don't naturally write.
