The record

What it does: The open-source tool turns video URLs or files into reusable notes.
Transcript workflow: The default workflow uses captions when available or transcribes audio with Whisper, then summarizes the transcript with an LLM.
Visual mode: Visual mode sends video, including visible content and audio, to a video-capable model without transcribing first.
LLM integrations: It works with OpenAI-compatible endpoints, with examples including OpenAI, Groq, Gemini, Ollama, OpenRouter, NVIDIA, and Perplexity.
Summary formats: Available summary styles include Q&A, distillation, fact-checking, tutorials, Mermaid diagrams, and essays, with custom styles added through prompts.json.
Interfaces: It provides a Streamlit GUI, CLI, optional HTTP API, Docker deployment, Raycast extension, and agent skill.
Caching: Transcript caching lets users rerun a video with different styles or providers without transcribing it again.
Prefiltering: Optional JEV prefiltering selects transcript passages before summarization and can include or exclude specified concepts.
Sharing: The webapp can publish a summary as a public rendered page through Tinypaste without an account or token.
Security and data handling: The project describes itself as local-first, and users configure provider API keys in a local .env file.
Notable sharing limit: Shared summaries are public pages, according to the sharing documentation.
Visual mode limits: The documented default visual limits are 120 seconds per request and 100 MB per file, with MP4, MPEG, MOV, and WEBM listed as supported formats.
Who it is for: The maker describes use cases including condensing podcasts, lectures, and conference talks, and extracting a key idea from social videos.
Supported sources: The maker lists YouTube, Instagram, TikTok, Twitter/X, Reddit, Facebook, Google Drive, Dropbox, and local files as supported sources.
