The audio to text converter that does more
MP3, WAV, M4A, AAC, or FLAC in — accurate, timestamped text out, ready to export in the format you need.
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 6 AI models — fast for drafts, highest-quality for verbatim accuracy.
- Your timestamped transcript lands in the library, ready to work with.
Accuracy where it counts
- 6 AI models tuned for different jobs — pick verbatim accuracy for interviews and research.
- Speaker labels separate voices in conversations and meetings.
- 100+ languages with built-in translation, including mixed-language recordings.
- About 30 seconds per hour of audio with the fast model.
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). Your files are deleted after transcription and never used to train AI models.
