Sonix
Sonix is fast multilingual transcription by the hour — $10/hr pay-as-you-go or Core $25/mo annual including 5 hours, with 50+ language translation.
Verified against: sonix.ai as of 2026-09-22
Quick verdict: Sonix is the localization value pick: a flat $10 per audio hour across 50+ languages, or $25/mo annual when usage is steady. Pick it for multilingual interviews and subtitle work where you need a clean transcript without a full video editor. The lack of a permanent free tier is the main caveat; Rev is better for tiny one-off volumes, Descript for editing. The subscription ladder is Core $25/mo bundling 5 hours, Advanced $50/mo and Pro $80/mo, with Core also available at $275/yr annual, and extra seats at $25/mo each with overage again at $10 per audio hour — so the per-hour price is identical whether you pay as you go or buy a bundle, which makes the decision purely about whether your volume is steady enough to justify a seat. Translation is where this tool pulls ahead of the field: 50+ languages at the same flat rate is uncommon, and the subtitle and caption export is clean enough to ship without a second pass. The honest caveat remains that there is no permanent free tier, only a trial, so a single short clip is cheaper on Rev.
