LessonScriptor – Live Transcription & Screenshots

Live captions, speech-to-text & voice-to-text — editable transcript with screenshots. Free mic + AI tab audio.

LessonScriptor is your online lesson assistant — a live transcription sidepanel for your browser that doubles as live captions, speech-to-text, or voice-to-text, for any tab. 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. —————————————————————————————— STUDYING WITH THE OPEN UNIVERSITY OR ANY DISTANCE-LEARNING PROGRAM? —————————————————————————————— If you're studying through The Open University, IGNOU, NIOS, or any other online or distance-learning program, LessonScriptor was built for exactly this. Open the side panel next to your course video, get your tutor's words transcribed in real time, and finish every module with a clean, editable transcript — instead of scattered notes or paused-and-rewound video. —————————————————————————————— 🆕 WHAT'S NEW IN 1.1.1 —————————————————————————————— • Capture screenshots of the video — added straight to your transcript, in sync with the lecture • Try 30 min free of AI mode — no signup, no credit card • New highlight colors: orange added, red is now more vivid • New formatting option: Strikethrough • One-click link to lessonscriptor.com from the popup and Settings • Helper for Microphone configuration —————————————————————————————— 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. **Known Limitations:** Mic mode is only compatible with Google Chrome. If you use a Chromium-based browser, you may see an error indicating that there is no connection available. However, tab audio mode will still function. Mic mode works well on Mac, but some Windows computers may experience issues. While the microphone can pick up external sounds and your voice, it may not capture sound coming from your speakers due to filtering. It could be helpful to adjust some microphone settings to improve performance. If these adjustments do not resolve the issue, tab audio mode will be the best option to ensure functionality. 🤖 TAB AUDIO MODE — WHISPER AI 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, ready for Notion, Obsidian, or any notes app —————————————————————————————— 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.
