The short answer: the best AI transcription tool depends on what you record. Otter.ai wins for live meetings, Rev wins when a transcript has to be right and a human needs to check it, and Sonix wins for uploaded files at a flat $10 per audio hour. Descript is the pick if you edit audio or video by editing text, Fireflies.ai is the strongest free meeting option — with one asterisk explained below — and TurboScribe has the most generous free tier for files. Every price and limit was checked on the vendor’s own pages in November 2026. This is research-based coverage, not hands-on testing.

What the pricing pages don’t make obvious
Three verified gotchas. First, Fireflies’ “unlimited transcription” free plan carries an asterisk: accounts created on or after September 1, 2026 get only 3 transcribed meetings unless Auto-join is turned on, which sends the Fireflies bot into your calendar meetings, and free storage stops at 400 minutes per team. Second, Rev’s $1.99/minute human rate is a base rate — Rev’s own pricing support page adds $0.30/minute for timestamping, $0.50 for verbatim and $1.25 for rush, so a rushed verbatim hour costs far more than the headline suggests. Third, Otter’s free plan allows only 3 file imports for the lifetime of the account, not per month.
1. Otter.ai — best for live meetings
Otter joins Zoom, Teams and Google Meet calls, transcribes live with speaker labels, and produces summaries and action items. The free Basic plan includes 300 minutes a month with a 30-minute cap per conversation. Pro is $16.99/month, or $8.33/month billed annually, for 1,200 minutes and 90-minute meetings; Business is $30/month, or $19.99 billed annually, with unlimited meeting transcription.
Pros: excellent live experience; generous meeting limits on Business. Cons: only six transcription languages; free file imports are nearly nonexistent. Best for: teams that live in meetings. We compared it head-to-head in Fathom vs Otter.ai.
2. Rev — best when it has to be right
Rev is the only tool here with a real human tier: AI transcription at $0.25/minute pay as you go (or via subscriptions starting at $29.99/user/month), and human transcription at $1.99/minute with a stated 99%+ accuracy and turnaround of 12 hours or less. That escalation path is why legal, research and media teams keep it on the list.
Pros: human fallback no rival here matches; clear per-minute pricing. Cons: add-ons stack fast; the free tier is a thin 45 AI minutes a month. Best for: interviews, depositions and research you may need to defend.
3. Sonix — best for uploaded files
Sonix transcribes uploaded audio and video at $10 per audio hour pay as you go, billed by the second, with no surcharge for extra speakers, accents or noisy audio — and 30 free minutes to start, no card required. The Core subscription is $25/month including 5 hours, which drops the effective rate to $5/hour, and Sonix adds subtitles and translation into 54+ languages on the same hours. Our full Sonix review covers its editor in detail.
Pros: the most predictable pricing in this list; fast turnaround of about 5–6 minutes per audio hour. Cons: no live meeting bot. Best for: podcasters, researchers and journalists working from files — see also our best AI tools for podcasters.
4. Descript — best for editing by transcript
Descript transcribes your audio or video and then lets you edit the media by editing the words. The free plan includes 1 media hour a month with watermarked 720p exports. Hobbyist is $16/person/month billed annually ($24 monthly) for 10 media hours; Creator is $24 annually ($35 monthly) for 30 hours and 4K exports.
Pros: transcription and editing in one step; strong AI cleanup tools. Cons: priced per person, and media hours — not transcription alone — are the meter that matters. Best for: video and podcast creators who publish what they transcribe.
5. Fireflies.ai — strongest free meeting tier, with an asterisk
Fireflies records and transcribes meetings across Zoom, Meet, Teams and more, in 100+ languages, with searchable transcripts and AI summaries. Pro is $10/seat/month billed annually ($18 monthly) with unlimited summaries and 8,000 minutes of storage per seat; Business is $19 annually ($29 monthly). Read the free-plan asterisk in the pricing box above before you rely on it.
Pros: deep meeting search; 100+ languages. Cons: free-plan conditions changed in September 2026 and are easy to miss. Best for: sales and support teams that search old calls. For meeting-only alternatives, see our roundup of the best AI meeting assistants for Zoom.
6. TurboScribe — most generous free tier for files
TurboScribe, powered by OpenAI’s Whisper, keeps pricing radically simple. The free plan transcribes 3 files a day, each up to 30 minutes, with no credit card required. The single paid plan, Unlimited, is $10/month billed annually ($120/year) or $20/month billed monthly, and removes the caps: unlimited transcription for one person, files up to 10 hours or 5 GB, and 50 files uploaded at once, across 98+ languages. One caution from its own terms: purchases are non-refundable, so test the free tier on your own recordings first.
Pros: a genuinely useful free tier; one flat unlimited price. Cons: files only — no meeting bot; non-refundable purchases. Best for: occasional file transcription without a subscription decision.
Frequently asked questions
What is the cheapest way to transcribe an hour of audio?
Sonix pay as you go: $10 per audio hour, billed by the second. Rev’s AI tier is $0.25/minute, which is $15 for the same hour, and its human tier is $119.40 before add-ons.
Which AI transcription tool is most accurate?
No vendor number is independently settled, which is why accuracy-critical work belongs with Rev’s human tier at $1.99/minute and a stated 99%+ accuracy — every AI-only tool here will need a human proofread on names and technical terms.
Is there a truly free AI transcription tool?
For meetings, Otter’s free plan gives 300 minutes a month and Fireflies’ free plan is unlimited only with Auto-join on for newer accounts. For files, TurboScribe’s free plan — 3 files a day, up to 30 minutes each — is a real ongoing tier, not a trial.
Can these tools transcribe languages other than English?
Yes, unevenly: Fireflies lists 100+ languages and Sonix 54+ for translation, while Otter lists six transcription languages. Check your language before paying.
