S2T is for people who'd rather read voice notes than listen to them. Forward a voice message, audio file or video note, and the bot replies with the text.

  • Skips silence for better accuracy
  • Splits long transcripts across messages
  • Optional allow-list to keep the bot private
  • Runs on a small CPU-only server, with no per-minute API costs
