Bolo Aur Likho is a free AI transcription tool that converts EdTech lectures and online classes in Hindi, Hinglish, and Indian languages into searchable study notes. No signup required.
India's EdTech market is one of the largest in the world. Platforms like Unacademy, BYJU'S, Physics Wallah, and hundreds of independent coaching institutes deliver lectures in Hindi, Hinglish, Tamil, Telugu, and other Indian languages. Students watching these lectures need text-based study materials and transcription bridges that gap instantly.
Why EdTech Needs Transcription
For Students
- Searchable notes: Convert a 2-hour UPSC lecture into text you can search with Ctrl+F. Find any concept, date, or example without scrubbing through video.
- Revision material: Transcripts become printable study notes. Highlight, annotate, and create flashcards from lecture text.
- Accessibility: Students who are deaf or hard of hearing get full access to audio-only lecture content.
- Offline study: Text transcripts work offline, consume no data, and can be shared easily via WhatsApp or email.
For EdTech Platforms
- SEO and discoverability: Publishing lecture transcripts makes your content searchable on Google. Students searching for specific topics find your lectures.
- Auto-generated captions: Transcripts can be converted to SRT subtitles for video accessibility compliance.
- Content repurposing: Turn lecture transcripts into blog posts, quiz questions, and revision guides.
- Engagement analytics: Analyze which topics students search for most in transcripts to inform content strategy.

Hinglish Lectures The Indian Reality
Most Indian EdTech lectures are in Hinglish Hindi sentences peppered with English technical terms. A physics lecture might say "अब हम momentum की conservation के बारे में बात करेंगे" mixing Hindi grammar with English physics terminology. Bolo Aur Likho handles this naturally, outputting Hindi in Devanagari and English terms in Latin script, producing transcripts that read exactly how the teacher spoke.
Accuracy for Lectures
On our benchmark tests, Hindi academic lectures achieve approximately 8.3% Word Error Rate meaning about 92 out of 100 words are transcribed correctly. Clean studio-recorded lectures (like those from major EdTech platforms) achieve even better accuracy. The main accuracy challenges are large lecture halls with reverb, fast-speaking teachers, and heavy regional accents.
