LessonScriptor

Transcribe any video, lecture, or meeting in real time. Free mic mode + AI tab audio. Export to TXT or Markdown.

LessonScriptor adds a live transcription panel to your browser. Open it while watching any lecture, video course, meeting, or webinar — and get a real-time transcript you can read, edit, and export. No complex setup. No separate app. Just click the extension icon, open the side panel, and start. —————————————————————————————— TWO TRANSCRIPTION MODES —————————————————————————————— 🎙 MICROPHONE MODE — FREE, ALWAYS Captures your microphone using your browser's built-in speech engine. No sign-in, no account, no credits — just install and start. Works for in-person lectures, conference calls where you're a speaker, or any situation where you can pick up audio through a mic. 🤖 TAB AUDIO MODE — WHISPER AI (via Groq) Captures the actual audio playing in your browser tab — the video, the instructor's voice, the meeting. Powered by OpenAI's Whisper model for high accuracy across a wide range of accents and speaking styles. Two accuracy levels: • Normal — processes in 10-second chunks. Fast and responsive. • Optimal — processes in 30-second chunks. Best accuracy for recorded lectures. Tab Audio runs on a credit system. Credits are purchased once, never expire, and cost as little as €0.60 per hour of transcription. Starter pack from €5. —————————————————————————————— WORKS EVERYWHERE —————————————————————————————— LessonScriptor works on any tab with audio — it doesn't matter what video player is used. Modern streaming platforms, password-protected institutional portals, legacy university systems with no caption support, corporate e-learning tools, live web meetings — all of it works the same way. The extension operates at the audio level, not the player level. If sound is playing in your tab, LessonScriptor captures it. There is no list of supported sites, no compatibility requirements, and no player integration needed. —————————————————————————————— MULTI-LANGUAGE SUPPORT —————————————————————————————— Transcribe in 14 languages with more coming: English (US & UK), French, Spanish, German, Italian, Portuguese (PT & BR), Chinese (Simplified), Japanese, Korean, Russian, Arabic, Hindi. Select the language before you start — that's it. —————————————————————————————— EDIT AS YOU GO —————————————————————————————— The transcript panel is a live editor. You can correct errors on the fly, add headings, highlight key phrases, write notes between passages, and restructure content — all while transcription continues. Formatting options: Bold, Italic, Underline, Headings (H1–H4), Color highlights, Bullet lists, Quote blocks. —————————————————————————————— EXPORT IN YOUR FORMAT —————————————————————————————— When you're done, export to: • .txt — plain text, universal • .md — Markdown —————————————————————————————— PRIVACY —————————————————————————————— LessonScriptor does not create accounts, does not collect your email, and does not store any personal data. There is no sign-up — ever. In Microphone mode: all processing happens locally in your browser using the Web Speech API. No audio leaves your device. In Tab Audio mode: audio chunks are sent to Whisper AI for transcription and not retained beyond the request. Transcripts are saved locally in your browser only and never transmitted to LessonScriptor's servers. Tab Audio credits are purchased via LemonSqueezy. Your payment and personal details are handled entirely by LemonSqueezy — LessonScriptor only receives an anonymous license key. That key is stored locally on your device. LessonScriptor does not track your browsing and does not sell data. —————————————————————————————— GET STARTED —————————————————————————————— 1. Install LessonScriptor 2.
