SpeechText.AI converts audio and video recordings into text and subtitles. Its Transcriber bot works inside Slack and Google Chat: you upload a file or share a public link, such as from Google Drive or Dropbox, and it notifies you when the transcript is ready.
Transcription usually takes around half the length of the recording. You can then edit and export the results. There is a free way to start, which makes it easy to test with your own files.
