Summarize WebM recordings

By the Potok teamUpdated ~2 min read

WebM often comes from a browser or screen recorder, and only its audio feeds the digest. To summarize WebM recordings, send the file to Potok in Telegram as 1 message. Slides or pictures will not appear in the summary, and echo from open speakers blurs the words, so test with 1 short clip first.

Send a file, get the text

Your recording goes to @potok_now_bot as a file or a voice message, and the transcript returns to you in Telegram.
