Sonix
Automated transcription that turns audio into searchable text
What it is
Sonix is an automated transcription service that converts audio and video files into text using AI, then lets you search, edit, and export transcripts in multiple formats. Journalists, podcasters, researchers, and video producers use it to speed up post-production workflows.

Frequently asked questions
Does Sonix have a free trial or free tier?
Sonix does not offer a permanent free tier. It has historically offered a limited free trial with a set number of minutes, but you should verify current trial availability on the site before signing up.
How accurate is Sonix transcription?
Accuracy is generally high for clean, single-speaker audio recorded in a quiet environment, often cited around 90-95%. It degrades with heavy accents, background noise, or overlapping speakers, so budget time for manual editing in those cases.
How much does Sonix cost per month?
Sonix starts at around $25 per month, with higher tiers for teams and heavier usage. Verify current pricing at sonix.ai since plans and per-minute rates can change.
How does Sonix compare to Otter.ai or Descript?
Otter.ai is cheaper and has a free tier but focuses more on live meeting transcription. Descript bundles audio and video editing with transcription, making it better suited for creators who want an all-in-one editor. Sonix is more focused on fast, accurate batch transcription with strong export options.
Can Sonix handle multiple speakers in an interview or podcast?
Yes, Sonix includes speaker diarization that attempts to label different speakers automatically. It works reasonably well for two or three speakers but often needs manual correction in group conversations or when voices are similar.
Is Sonix suitable for non-English content?
Sonix supports transcription in over 54 languages, so it is a viable option for multilingual creators. Accuracy in non-English languages varies and is generally lower than for English, so test with a sample file in your target language first.
