# Idea to PRD

Start with a few sentences. Murmur researches the competition and writes the product requirements document.

Murmur by SprintZero Studios turns a product idea into a product requirements document. You type the idea or record it, Murmur researches competitors with live web search, and writes a PRD with must, should, could and won't-have features, a reason for each, success metrics, non-goals, risks and open questions. Targets you didn't give are marked as assumptions. Runs usually finish in minutes; the eight public example runs took 7m 31s to 11m 05s.

Jira and Confluence are optional: connect a free Atlassian site and choose them when you run an idea.

## A real run: Micro-Tool Agent

Someone on X asked Grok to build them a SaaS. Grok's 39-word reply was typed into Murmur word for word, and that was the whole input. This is the PRD Murmur wrote from it.

- 39: Micro-Tool Agent typed idea, words
- 9m 29s: Micro-Tool Agent run
- 6: competitors researched, each with a link
- 15: PRD features (8 must, 3 should, 4 could)
- 8: won't-haves
- 8: open questions

Typed idea:

> AI agent that builds, markets, and sells micro-tools while you perfect the logo. Target: indie hackers chasing MRR. Outreach + close scripts ready. Stripe link hits your account after first 5 sales. Drop the niche or I invent one.

| In the idea | In the PRD |
|---|---|
| “Drop the niche or I invent one.” | Must have: “Niche input or agent-invented niche”. Why: quotes that line. |
| “Outreach + close scripts ready.” | Must have: “Outreach and close scripts”, and a should-have the idea didn't ask for: “Approval gate before outreach”, to limit spam risk. |
| “Stripe link hits your account after first 5 sales.” | Must have: “Sales-gated Stripe handover”, with its meaning sent to the open questions instead of guessed. |
| “while you perfect the logo” | Won't have: “AI logo and brand identity generation”, one of 8 won't-haves. |
| No product name. | Open question: “Product name: the founder gave none; a name is needed (working title used here).” |
| No targets. | Success metric: “Share of launched micro-tools that reach 5 sales (the handover trigger), measured from Stripe sales records”, target tagged [assumption]. |

Every feature carries a reason: a line from the idea, a finding from the research, or a recommendation Murmur labels as its own. What the idea leaves unclear becomes an open question, and every target the founder didn't give is marked [assumption].

## Steps

1. **Sign in.** Create an account. Your first idea is free, with no card.
2. **Want Jira and Confluence too? Choose them.** Jira and Confluence are optional: connect a free Atlassian site and choose them when you run an idea. A run you choose them for also gets a Jira project and Confluence space in your own site.
3. **Type or record the idea.** On a computer, type it in the Murmur app or record it; on a phone, record it (15 seconds to 10 minutes). You can also send it as text from Claude Code through Murmur's MCP server. Say what it does, who it's for and why now; a few sentences is enough to start.
4. **Start the run.** For a memo, Murmur shows the transcript first, and nothing runs until you confirm it.
5. **Open your PRD.** Download it as Markdown, alongside the competitor map, brand kit, tech design, roadmap and board from the same run.

## What's in the PRD

- One-liner
- Problem
- Target user
- Features as must / should / could / won't, each with a reason
- Success metrics, with assumed targets tagged
- Non-goals
- Risks
- Open questions
- A competitive landscape, from a competitor map with a source link for every competitor

The PRD is one of eight artifacts from the same run, and the board is built from it.

## FAQ

### Can AI turn a product idea into a PRD?

Yes. Murmur takes the idea as its only input, researches competitors with live web search, and writes a PRD with prioritised features, a reason for each, success metrics, risks and open questions. In the Micro-Tool Agent run, a 39-word idea became a PRD with 15 features and 8 won't-haves.

### How much do I need to say?

A few sentences can be enough: the Micro-Tool Agent idea was 39 typed words. Type it in the Murmur app on a computer, record a memo of 15 seconds to 10 minutes on any device, or send 20 to 600 characters through the MCP server. Saying who it's for and why sharpens the PRD.

### Is this an AI PRD generator?

Yes, but it researches before it writes. Most PRD generators draft from your prompt alone. Murmur first maps competitors, with a source link for each, then writes the PRD, the tech design, the roadmap and a board from the same run.

### Does Murmur make things up?

It labels what it infers. Every feature's reason quotes the idea, cites the research or is marked as Murmur's recommendation; every target the founder didn't give is tagged [assumption], and anything unclear becomes an open question. In the Micro-Tool Agent run, the idea named no product, so the PRD asks for one.

### Do I need Jira or Confluence?

No. Everything stays in Murmur, and the PRD downloads as Markdown. Jira and Confluence are optional: connect a free Atlassian site and choose them when you run an idea. A run you choose them for also gets a new Jira project and Confluence space in your own site.

### How is this different from a PRD template?

A template gives you the sections; you fill them. Murmur fills them from your idea and its research, with a reason for every feature. Want to write it yourself? The free PRD template uses the same sections.

### Can I edit the PRD?

Yes. It downloads as Markdown, and if you chose Confluence for the run, the Confluence copy is yours to edit like any other page.

### How long does it take?

Usually minutes. The eight public example runs took 7m 31s to 11m 05s. You don't have to watch: close the tab and Murmur lets you know when it's ready.

### What does it cost?

Your first idea is free, with no card. After that it's $7 per idea, or a monthly plan. A failed run doesn't use up an idea.
