Why TubeGist

Built for builders who refuse subscription bloat

Stop letting browser tabs turn into a chaotic graveyard of unread tutorials.

The Cloud SaaS Trap

Web extensions and bloated cloud summarizers

✕ $20/month recurring tax ($240/yr) just to summarize YouTube transcripts you already stream for free.
✕ Electron memory hogs spinning laptop fans and devouring 1.5GB+ of system memory in the background.
✕ Cloud surveillance: your watch history, queries, and study notes are stored on remote third-party databases.
✕ Lost when offline: board a flight or lose Wi-Fi, and your entire knowledge library becomes inaccessible.

Frequently Asked Questions

Everything you need to know about TubeGist, licensing, and privacy.

TubeGist uses a local-first architecture. It fetches clean YouTube captions directly or transcribes them via local Whisper, normalizes the text with a native Rust core, and sends an optimized prompt via your own API key (like Gemini Flash, which offers a massive free tier). This eliminates expensive cloud SaaS markups and lets you pay $19 once.
