Which AI tools transcribe audio to text most accurately?
Last verified 2026-10-10Paid placement never changes our picks.
Short answer
As of October 2026, start with Sonix if you want an upload-and-edit web app with speaker labels, AssemblyAI if you need a developer API with a large free allowance, and MacWhisper if your audio must stay on your Mac. The main catch: published accuracy figures are vendors' own claims, so test two tools on your own recording.

Prices come from each tool's fact block. "See pricing page" means we have not confirmed the number on the official pricing page in the last 30 days, so we do not show one.
How to choose
- If accuracy matters most → run the same 5-minute clip (your accents, your noise) through two free tiers and count the errors that matter to you: names, numbers, jargon. Vendor benchmarks contradict each other.
- If your audio is not in English → match the language list: ElevenLabs Scribe lists 99, AssemblyAI's newest model 18 (its older model 99), Deepgram 45+, Sonix 54+, Happy Scribe 150+.
- If you need a human-checked transcript for legal or publishing use → Rev or Happy Scribe, which both sell human transcription next to AI.
- If the audio must not leave your computer → MacWhisper, which runs local models on a Mac (one-time licence in euros).
- If you are building transcription into a product → AssemblyAI, Deepgram or the ElevenLabs API, billed by usage; for meeting notes rather than files, see /ask/ai-meeting-note-taker.

Where sources disagree
- Accuracy claims: Several vendors each claim their model is the most accurate, and these claims conflict. We found no independent benchmark and did not rank by accuracy.
- Happy Scribe language count: Happy Scribe's pricing page states 150+ languages on one line and 60+ on another. Check your language in its list.
- ElevenLabs Scribe free minutes: The Scribe pricing table implies about 12 free minutes, while the shared-credit figures imply more. Re-check in your account.
- Rev positioning: Rev's pricing page now leads with legal and evidence tools, so general-use terms may differ from what the page emphasises.
