Show HN: OpenBrief – Local-first video downloader/summarizer

Summary

OpenBrief is a pnpm/Turborepo workspace centered on a Tauri v2 desktop app. It supports importing local media or video URLs, downloading media through bundled tools, transcribing audio, generating grounded summaries, chatting with media context, organizing playlists, and exporting reusable notes. 📥 Import anything — paste a video link or import a local audio/video file. ✍️ Transcribe locally — extract captions or run on-device speech-to-text. 📝 Grounded summaries — generate blog-style markdown briefs with timestamped takeaways. 💬 Chat with media — ask questions against the summary or full transcript. 🔊 Listen back — turn summaries into audio with text-to-speech. 🔒 Open source & private — runs on your machine, free to use. Build a searchable library from video links or local files, then extract transcripts and keep everything in one place. Open any item to read the transcript, generate a grounded summary, and chat with the media context side by side.
