The record

Purpose: MomentSearch is visual video search and retrieval-augmented generation software that returns exact video moments matching what is seen and said.
Input: Users can upload videos or paste YouTube URLs for indexing.
Retrieval: The system always searches both a visual frame branch and a transcript branch, then fuses their results.
Citations: Answers cite clickable moments with matched keyframes, timestamps, transcript synchronization, seen or said badges, and match scores.
Uploads: Presigned uploads send gigabytes directly from the browser to object storage instead of through the API.
Speaker recognition: Optional per-video speaker recognition uses Gemini video understanding and requires a Gemini API key.
Abstention: A confidence gate can abstain without making an LLM call when neither retrieval branch clears its threshold.
Deployment: The project ships as a neutral Docker image with api, worker, clip, and one-shot seed entrypoints, and documents Fly, AWS, and Google Cloud deployment.
Storage integrations: Object storage supports local storage, AWS S3, GCP storage, GCP native storage, and Fly Tigris, while the architecture uses Postgres, Qdrant, and Prefect Cloud.
Security limit: The API is unauthenticated; anyone who can reach its port can mint upload URLs, ingest, ask, and delete, so the README recommends localhost binding or an authenticating proxy.
User model: The application is single-user by default and ignores X-User-Id and Authorization headers, routing every request through SINGLE_USER_ID.
YouTube ingestion limit: The documented SocialKit YouTube ingestion option provides 20 free credits and then becomes paid, while cookie authentication is free but cookies expire approximately every two to three weeks.
License: MomentSearch is released under the Apache 2.0 license.
Maker privacy: Traversaal.ai says it uses strictly necessary authentication and usage cookies and does not use cookies for advertising, analytics, or tracking.
