VoiceDebrief: a product with no server that shipped in three weeks and stopped at the one thing it could not sell

VoiceDebrief.ai turns a voice note into a transcript, a translation and a debrief in the browser, on the user's own OpenRouter key, with no account, no server and nothing stored; a 42-second note costs about a third of a penny. Built in the open from 28 July 2026: 239 commits and 27 releases in the first three weeks, then eleven commits the week after, then three, and a last commit on 7 September. What stopped it was not a server but the lack of one: the capped key per user that the model needed is forbidden by the provider's terms, and the alternative, a metering proxy, is the backend the product exists to avoid.

Decided by. Nobody yet: a candidate for Dinis to read, comment on and decide (keep, rewrite, merge, cut, article first, later, not doing it).

Note. Dated 12 October 2026; Dinis says he is involved in VoiceDebrief and that the commit counts show when the work stopped, not why. The four routes: buy a capped OpenRouter key per user (forbidden by the standard terms); a provider that sells the capped key itself or lets it be issued under its terms (ElevenLabs the nearest fit, the gap is one sentence); bring your own key, kept (what runs today, honest, no margin, and the five minutes it takes to get a key is where most people stop); a metering proxy (the smallest backend, and a backend, custody and on-call return). The one part of the product with a server is the WhatsApp path, an n8n workflow behind a Cloudflare Worker. The method at the end is worth the book's attention: agents draft the letters to providers, Dinis sends, the ask is one sentence, and every answer is recorded as an issue with its date so the map is updated as a version rather than a new article.
