Example workflows

Turn a meeting recording into notes

Upload an MP3, M4A, or MP4 meeting recording, generate the transcript, then copy it into your notes app to extract decisions, owners, and next steps.

Create a caption draft from a video

Upload an MP4 or WebM file, transcribe the spoken audio, then use the timestamped output as a starting point for subtitles or social captions.

Convert voice memos into text

Export a phone voice memo as M4A or MP3, run speech-to-text in the browser, then clean the transcript into a draft, journal entry, or task list.

Tips for Better Results

  • Record close to the speaker whenever possible.
  • Reduce background music, room echo, and overlapping speakers.
  • Split very long recordings into shorter files for smoother browser performance.
  • Use WAV or M4A when quality matters, and MP3 when smaller file size matters.

Why use SuperTextHub?

Files are processed in your browser and are not uploaded to SuperTextHub. The tool is free, does not require an account, and supports transcript copy or download workflows.

Troubleshooting

The file will not load

Try MP3, WAV, M4A, MP4, or WebM. Some browsers cannot decode every codec inside every media container.

The transcript is inaccurate

Use a clearer recording, reduce noise, and make sure the selected language setting matches the speaker when auto-detect struggles.

The first transcription is slow

The browser needs to download and cache the AI model. Later transcriptions are usually faster on the same device.
