Due on every single ship

Release Notes Writer

“What’s New” is the only listing field you rewrite every release, and it falls due at the least interesting moment of one — which is how it ends up as “bug fixes and performance improvements”. Paste your changelog; get copy in your own voice, in three lengths.

Why bother

The “What’s New” block sits on your product page and in every user’s Updates tab. It is the only place a lapsed user is told that the thing they left over has been fixed — and the only listing field where writing “bug fixes” costs you that. Pick your app above.

Turn a raw changelog into release notes people read

The What’s New field reaches every existing user through the Updates tab, and most of it reads like it was written by a build script. Paste your raw changelog and this drafts three lengths — a short line, a bulleted set and a detailed version — in your app’s own voice.

Your previous release notes are passed as a VOICE SAMPLE only, and shown on screen so it is obvious what the draft is modelled on. The previous release’s content is not shipping again.

How it works

  1. 1Pick your app. Its live listing supplies the voice sample.
  2. 2Paste the raw changelog — commit messages, ticket titles, whatever you have.
  3. 3One AI call returns three lengths as structured output, each validated against Apple’s 4,000-character cap.
  4. 4The output box is editable and the copy button copies your edit, not the model’s draft.

What it cannot tell you

  • The prompt says the changelog is the only source of facts and forbids invented features, thanks, teasers and numbers — but being TOLD not to invent is not the same as being unable to. Read the draft against your changelog before shipping it. An invented feature here is a public claim about software you shipped.
  • Filler phrases like "bug fixes and performance improvements" are flagged as a warning, not an error: a genuine maintenance release has nothing else to say, and forcing text there is how the field gets padded with invention.
  • It cannot see your code. It only knows what you paste.

Frequently asked questions

How long can App Store release notes be?

4,000 characters, the same cap App Store Connect enforces on the What’s New field. All three drafts are validated against it.

Is "bug fixes and performance improvements" bad?

Only when it is untrue. If the release genuinely is maintenance, that is an honest note — which is why it is flagged as a warning rather than blocked.

Do release notes affect ranking?

Apple publishes no such factor. What they demonstrably do is reach existing users in the Updates tab, which is a retention surface rather than an acquisition one.
