The audio to text converter that does more

MP3, WAV, M4A, AAC, or FLAC in — searchable text out, ready to review and export. Timestamps depend on the selected mode.

Every common audio format, one converter

Silestis accepts MP3, WAV, M4A, AAC, and FLAC uploads directly. Got video instead? MP4, MOV, MKV, AVI, and WebM work too — the audio is extracted automatically. And if the recording lives online, paste its link instead of uploading at all.

How it works

  • Upload your audio file, or paste a link to the recording.
  • Pick one of 3 focused AI modes — fast transcription, long-form translation, or speaker labels.
  • Your transcript lands in the library, ready to work with; timestamps depend on the selected mode.

Accuracy where it counts

  • 3 focused AI modes tuned for fast transcription, long-form translation, and speaker-labelled interviews.
  • Speaker labels separate voices when Speakers mode is selected.
  • Broad multilingual transcription and translation; exact language and mixed-language support depends on the selected mode.
  • Background processing, with time depending on duration, format, selected mode, and load.

Not just conversion — understanding

Once converted, your audio becomes something you can work with — paid plans add semantic search across every transcript, AI answers with clickable [mm:ss] timestamps, and auto-generated notes, chapters, and flashcards. Export as TXT, PDF, or DOCX (SRT/VTT with timestamp-capable models). Source media is deleted after transcription by default unless you keep a playback copy. Silestis does not use your content to train its own models.
