Image and video decision
VidNotes
VidNotes is open-source and self-hostable (repo available), so a technical user can stand up a useful replacement by running the upstream project or implementing a minimal stack; keep paying only for convenience and hosted integrations.

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All VidNotes alternatives, with the arithmetic →
What a replacement has to do
- Given a video URL or file, download/extract audio, run speech-to-text, generate timestamped transcript, run an LLM to produce summaries/key points/flashcards, and expose results via a simple web UI and API.
What it still won’t have
- Official iOS / Android apps and App Store / Play Store distribution
- Chrome extension and browser integration shipped by VidNotes
- Polished UX, analytics, and priority support
- Built-in MCP/Claude/Codex integrations and one-account-scoped managed API key system
- Any proprietary operational scaling, monitoring, and background-job infrastructure provided by VidNotes
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a minimal self-hostable VidNotes-like service using Node.js (Express) backend, React frontend, Postgres, Redis for job queue, Docker, and GitHub Actions for CI. In scope: accept a public video URL (YouTube), download/extract audio, transcribe audio with OpenAI Whisper (or local Whisper backend), generate summaries/flashcards/QA with an LLM (OpenAI/GPT-compatible), store transcripts and derived artifacts in Postgres, provide REST endpoints /v1/analyze and /v1/transcripts/:id, a minimal React UI to paste a URL and view transcript with timestamps, and a small CLI that calls the API and outputs JSON. Explicitly out of scope: mobile apps, Chrome extension, MCP server, multi-account billing, and rendered clips/thumbails. Include proper error handling (network/timeouts/transcode failures), background job retries, basic auth for the API (API key), Docker compose and deployment instructions, and automated tests for transcription, summary generation, and key endpoints.

- Evidence score99
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
