Source provenance
Every completed record shows the source host, acquisition method, fetch time, segment counts, timed coverage, and raw source link.
Evidence-first platform
Video intelligence you can inspect before you act.
UVAI treats captions as evidence, keeps provenance visible, persists every workflow run, and puts a deliberate review boundary in front of external execution.
What is implemented
Clear evidence, durable state, controlled action.
Timed captions
The transcript is built from backend-acquired caption segments with real timestamps. Unlabeled captions remain labeled as captions.
Evidence quality gate
Export and success states stay blocked unless transcript evidence passes structural and provenance checks.
Durable workflow runs
Each analysis receives a run ID, persists its result, and can resume polling after a browser refresh.
Grounded AI synthesis
The model receives the verified transcript and returns summary, topics, and proposed actions without reconstructing missing source content.
Review before execution
Action preparation executes nothing. A second confirmation is required for the exact reviewed plan, and external writes are labeled.
Interactive playback
The YouTube player, seek timeline, and caption timestamps stay connected so users can inspect the source while reviewing conclusions.
Verified export boundary
Exports are enabled only after the quality gate passes; failed acquisition never turns into a synthetic package.
Protected paid AI routes
AI endpoints use a tighter budget and fail closed in production when distributed rate limiting is unavailable.
Runtime contract
These are the boundaries the current build enforces, not future roadmap promises.
