Summarize It

Instant text, video & audio summaries on iOS Flutter client · Python (llmlingua) & Node.js (Whisper) services · MongoDB · RevenueCat IAP

Summarize It distills long-form content into concise take-aways so users can “read the gist” instead of wading through hours of material. Inspired by the live App Store release, our open-source rebuild keeps the spirit but swaps in a modern, developer-friendly stack.
