Comparing transcription service rates side by side, PlainScribe is the cheapest AI option at $0.067 per minute (~$4/hour), undercutting Sonix (~$0.167/min), Rev AI ($0.25/min), and Rev human ($1.50/min). Subscription services like TurboScribe ($10/mo) can be cheaper per minute, but only at consistently high volume. Here's how each provider's rate plays out at real usage levels.
This post compares specific providers' rates head to head. If you want the underlying transcription rates rate card or the broader transcription cost picture, start there. Here, the focus is which service costs least for your situation.
Two billing models make direct comparison tricky:
The fair comparison is total monthly spend at your volume, not the headline number.
| Service | Rate | Per hour | Model | Best for | |---|---|---|---|---| | PlainScribe | $0.067/min | ~$4.00 | Pay-as-you-go | Lowest per-minute, variable volume | | Sonix | ~$0.167/min | ~$10.00 | PAYG or $22/mo | Built-in editor | | Rev (AI) | $0.25/min | ~$15.00 | Pay-as-you-go | One-off premium AI | | Rev (human) | $1.50/min | ~$90.00 | Pay-as-you-go | Legal / medical accuracy | | TurboScribe | $10/mo | Flat | Subscription | Consistent high volume | | Descript | $24–$33/mo | Flat | Subscription | Video editing workflow | | Otter.ai | Free + paid Pro (per seat) | Per user | Subscription | Live meetings |
Verdict: PlainScribe has the lowest per-minute service rate. Only commit to a flat subscription if you reliably transcribe 15+ hours every month.
The same audio costs wildly different amounts depending on the service:
| Volume | PlainScribe ($0.067/min) | Rev AI ($0.25/min) | Rev human ($1.50/min) | |---|---|---|---| | 5 hrs/mo (300 min) | $20.10 | $75.00 | $450.00 | | 10 hrs/mo (600 min) | $40.20 | $150.00 | $900.00 | | 20 hrs/mo (1,200 min) | $80.40 | $300.00 | $1,800.00 |
Against flat subscriptions, PlainScribe stays cheapest until usage is both high and consistent. A $16.99/month plan only beats $0.067/min above about 254 minutes (4.2 hours) every month; a $10/mo unlimited plan wins for steady heavy users but still charges you in a quiet month, while PlainScribe charges nothing.
PlainScribe avoids these: one rate, no subscription, prepaid credits valid for a year, and a private-by-design auto-delete after 7 days.
The cheapest service isn't universal — it depends on how you work:
The honest move is to estimate your real monthly minutes first, then pick the model that's cheapest at that number — not the lowest headline rate.
Which transcription service has the cheapest rates? On a per-minute basis, PlainScribe at $0.067/min (~$4/hour) is the cheapest AI service. Flat subscriptions like TurboScribe ($10/month unlimited) can be cheaper per minute, but only if you consistently transcribe enough hours to justify the fixed fee.
How do PlainScribe's rates compare to Rev's? PlainScribe charges $0.067/min versus Rev's $0.25/min for AI — about 3.7x cheaper for comparable accuracy on clean audio. Rev's human transcription at $1.50/min is roughly 22x PlainScribe's rate and is worth it only for accuracy-critical work.
Are subscription transcription services cheaper than pay-as-you-go? Only at consistent high volume. Below about 4–10 hours per month, pay-as-you-go at $0.067/min usually costs less because you pay only for what you use. A flat subscription charges the same in busy and quiet months alike.
Do transcription services charge per seat? Some do. Otter.ai and Fireflies bill per user, so a five-person team pays five times the per-seat rate. PlainScribe has no per-seat fee — one account, one rate, billed only on minutes transcribed.
Can I test a service's accuracy before paying? Yes with PlainScribe — 30 minutes free, no credit card. Running your own hardest audio through a free trial is the most reliable way to judge whether a service's rate is worth it.
