Exam-time search over your own lectures, 100% on-device (vectors never leave it): - EmbeddingEngine (transformers.js feature-extraction via the CDN loader, multilingual-e5-small 384-dim, e5 query/passage prefixes); native stub. - Vector store in StorageRepo (Dexie v3 + native v3 segvecs): upsertVectors, brute-force cosine searchVectors (course-scoped), clearVectors, unembeddedIds. Cascades: re-embed on segment edit, reassign updates vector courseId, deletes cascade. - Hybrid search: semantic candidates + lexical rank fused via reciprocal-rank-fusion (pure, tested); searchLectures() returns segment hits tagged semantic/lexical/both. - embeddingStore: build-index/backfill with progress + embed-on-save (fire-and-forget). - Search screen: query -> segment hits (snippet · course · time) -> tap jumps the transcript to that timestamp (seek + scroll-into-view). Per-course stats on Courses. 25 repo tests (incl. cosine ranking + course scoping), 13 search tests, 170 total green. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Welcome to your Expo app 👋
This is an Expo project created with create-expo-app.
Get started
-
Install dependencies
npm install -
Start the app
npx expo start
In the output, you'll find options to open the app in a
- development build
- Android emulator
- iOS simulator
- Expo Go, a limited sandbox for trying out app development with Expo
You can start developing by editing the files inside the app directory. This project uses file-based routing.
Get a fresh project
When you're ready, run:
npm run reset-project
This command will move the starter code to the app-example directory and create a blank app directory where you can start developing.
