Quince Service

Local-first AI processing backend

The Quince backend for structured voice-note intelligence.

This service turns transcripts from the iOS app into summaries, sections, key points, action items, and tags. Audio can stay on-device while your API keeps the OpenAI key safely on the server.

01

Server-owned secrets

OPENAI_API_KEY lives only in Vercel environment variables. The iOS app never needs direct provider access.

02

Structured outputs

The backend asks OpenAI for strict JSON so your app can save summary blocks, tags, sections, and action items without brittle text parsing.

03

Transcript-first flow

The first version expects transcript text from the app, which keeps raw audio local and reduces backend complexity from day one.
