BananaLingo

BananaLingo — open the YouTube transcript, translate it, and turn it into a long-form article with ChatGPT / Claude / Gemini.

BananaLingo turns any YouTube video into readable, translatable text — and then into a full article with the AI assistant of your choice. 🍌 WHAT IT DOES ▶ Instant transcript Opens YouTube's transcript panel automatically when you watch a video — no digging through menus. A compact toolbar appears right inside the panel, showing the video title with collapse/expand controls. 🌐 One-click translation Translate the entire transcript (and the video title) into 15+ languages including English, ไทย, 日本語, 中文, 한국어, Español, Français, Deutsch, Tiếng Việt, Bahasa Indonesia, Русский, Português, हिन्दी and العربية. Switch back to the original at any time. 🤖 Send to your favorite AI Press one button to send the full transcript to ChatGPT, Claude, or Gemini. BananaLingo builds a ready-made prompt that asks the AI to write a polished long-form article from the video, opens the AI site in a new tab, and auto-fills the prompt into the chat box. Just press Enter. 📋 Full text & copy View the transcript as continuous full text, or copy everything to your clipboard with one click — perfect for notes, research, and study. 🛟 Reliable by design If auto-fill on the AI site ever misses, your prompt is already in the clipboard as a fallback — paste and go. WHO IT'S FOR • Content creators repurposing videos into blog posts and articles • Language learners who want side-by-side transcript translation • Students and researchers summarizing lectures and talks • Anyone who prefers reading to watching PRIVACY BananaLingo runs entirely in your browser. It does not collect, store, or transmit your personal data to any server of ours.
