The problem
Why not just prompt the agent directly
Because a vague prompt produces scope creep, invented features and decisions that get reopened three sessions later. A spec is what stops that — and writing one by hand takes an afternoon most people would rather spend building.
1.0Intake
Give it what you already have
Photos of notebook pages, a voice note on the walk home, a paragraph typed at midnight. A vision model reads the handwriting and the arrows; Whisper takes the voice note. No account, no form to fill in.

- voice note“Nobody ever sees the four hundred photos I come back with.”
- typedShare by link. No account for the people I travelled with.
2.0Mirror
Check what it understood
Everything comes back as a handful of bullets, each one citing where it came from — and the contradictions arrive already flagged. Correct any of them; everything after this is built on your wording, not the model’s.

- Every album is public — and no album is visible to anyone but me.typed
3.0Interview
Answer only what is missing
At most seven questions, and only about what your material never said. Skip one and the decision is recorded as an assumption in the spec instead of quietly invented.
Who is this mainly for?
4.0Spec
Take it to your agent
Ten sections written to be executed rather than read: goals, non-goals, acceptance criteria, decisions. Download PRD.md and point Claude Code, Cursor or Codex at it.
## 3. Goals & success metrics - G1: A returning traveller publishes an album in under two minutes from landing. - G2: 60% of invited friends open the link without creating an account. ## 4. Non-goals (do NOT build) - ❌ No editing tools. This is not Lightroom. - ❌ No public feed, no follower graph.
Scope
What it will not do
It does not write your application code. It does not invent a feature you never mentioned — anything it had to assume is written down as an assumption, in the spec, where you can argue with it. And it does not keep your material: uploads are deleted after thirty days.
If you want more
One payment, one project
The spec is free and yours. If you would rather start from something sharper, a one-time build pack refines it with a frontier model and adds the context file and task list your tool expects — CLAUDE.md, AGENTS.md or Cursor rules, whichever you use. No subscription, ever.
Free

The whole flow and a PRD.md you can download. An account only at the download, nothing before it.
€7
Starter pack
A frontier-refined PRD, an agent context file matched to your tool and stack, and a tasks file in your tool’s convention.

Pro pack
Everything in Starter, plus project-specific skills and a scaffolded repository in your GitHub.

Before you start
The questions people ask first
- Do I have to create an account?
- Not to use it. Photos, voice notes, the summary, the questions and the spec itself all work signed out. The account is asked for once, at the download, so the file has somewhere to belong.
- What happens to my photos and voice notes?
- They are read once, turned into text, and deleted after thirty days. They are not used to train anything — the models are hosted, not ours to train.
- Which models read my material?
- Whisper for voice notes, Mistral Small 3.1 for photographs, Qwen3 for the writing — all on Workers AI, all on the free lane. Frontier models are only ever reached after a purchase, and only for that project.
- Will it write my application code?
- No, and that is deliberate. It writes the spec your agent builds from — goals, non-goals, acceptance criteria, decisions. Generating the app itself is what Lovable and Bolt are for.
- Does it work with Cursor and Codex, or only Claude Code?
- All three. The tool you pick decides which files a build pack writes:
CLAUDE.md, Cursor rules orAGENTS.md. - Can I change what it wrote?
- Every section, three ways: edit it by hand, ask for it again, or ask for more detail. Editing by hand is unlimited — it costs us nothing.
- Is there a subscription?
- No. The spec is free, and a build pack is a one-time payment for one project. There is nothing to cancel.
