How much does audio transcription cost in 2026? Humans, AI and the free plan
You have a one-hour meeting recorded and you need it in text. You search “how much does audio transcription cost” and get three answers that don’t agree with each other: R$4, R$600 and R$0. None of them is wrong. They just use different units — and that’s where most people choose based on the wrong number.
This guide puts the three pricing models side by side, with market rates published in 2026, and shows where each one hides the real cost.
Why the transcription bill is misleading
Transcription is sold in three units that don’t convert into each other automatically:
- Per minute of audio — the standard for human services and pay-as-you-go AI.
- Monthly subscription — the standard for meeting apps, almost always priced in dollars.
- Free with a ceiling — the free plan, where the cost shows up as a limit, not as an invoice.
Each unit hides a different cost. In per-minute pricing, the hidden cost is turnaround time. In a dollar subscription, it’s the exchange rate plus IOF. In a free plan, it’s the ceiling that runs out in the middle of your busiest week. Comparing only the number on the screen is the fastest way to overpay for something you didn’t need.
How much human transcription costs in 2026
The Brazilian human transcription market charges per minute of audio, with a range defined by the type of content and the deadline:
| Type of audio | Price per minute | A one-hour meeting | Typical turnaround |
|---|---|---|---|
| Clean audio, 1 or 2 speakers | R$3 to R$6 | R$180 to R$360 | 2 to 5 business days |
| Meeting with multiple speakers | R$8 to R$15 | R$480 to R$900 | 24 to 72 hours |
| Legal, medical or technical | R$10 to R$15 | R$600 to R$900 | 24 to 72 hours |
Read the third column before the first. One hour of meeting transcribed by a human costs between R$180 and R$900 — and it arrives later. For board minutes or a deposition with formal validity, that’s the fair price of human accountability. For everything else, it’s expensive for the wrong reason: you’re not paying for accuracy, you’re paying for the scarcity of human time.
How much AI transcription costs when you pay by the minute
The AI platforms that charge for usage work in a much lower range: somewhere between R$0,075 and R$0,50 per minute of audio. Converted, an hour comes out to R$4,50 to R$30, delivered in minutes instead of days.
The model has two traps. The first is volume: send 200 hours of interviews when you only need 10 and you paid for 200. The second is audio quality — the cheapest range tends to be the most sensitive to bad recordings, and the cost of manual review vanishes from the math. We’ve already shown how the audio is almost always the culprit when a transcript comes out wrong; no per-minute price makes up for a recording nobody can understand.
How much a dollar subscription costs (and what the invoice adds up to)
This is where most meeting apps live — and where the price on the screen stops being the price you pay.
With the dollar around R$5,20 and a 3.5% IOF on international card purchases, plus the spread the bank builds into the conversion, a US$16.99 subscription comes to more than R$91 per month. On the annual plan, US$8.33 lands around R$45 per month. 2026 surveys of the real cost of international purchases put the total — exchange rate, spread and tax — close to 10% above the rate used in back-of-the-envelope math.
And the free versions of these apps have a detail that decides more than price:
- Otter.ai — 300 minutes per month, with a 30-minute cap per conversation and only 3 file imports over the entire life of the account.
- Notta — 120 minutes per month, with a 3-minute cap per recording.
- Fathom — unlimited recording and transcription on the free plan, with advanced summaries limited to a few calls per month.
Notice the second number in each line. In two of them, the per-recording cap is shorter than any real meeting: the monthly limit never becomes the problem, because the recording stops first. A “120 minutes per month” plan with a 3-minute cap per conversation covers 40 voice messages and not a single meeting. That’s why, when we compared the best free transcription apps, the first column of the table is the per-recording cap — not the minutes in the ad.
What about Sintesy’s free plan?
Sintesy’s free plan uses another unit: the day. You get up to 60 minutes of content per day (audio, video, PDF, YouTube, meeting link) and up to 10 syntheses per day. The limit resets the next day — it’s not a monthly quota you burn through in the first week and then spend staring at the calendar.
What the free plan really delivers: upload the file, generate the synthesis, read the structured summary, navigate the mind map and use chat to ask the content questions. You see a preview of about 20% of the full result — enough to judge the quality of the transcription on your audio, not enough to walk away with an entire piece of content.
What stays locked on the free plan: exporting to PDF or DOCX, sharing by link, generating the synthesis podcast and using the WhatsApp integration. All of these are Pro features, along with transcription with no limit on hours or on volume.
What Pro costs: R$39,90 per month or R$149,90 per year, which works out to R$12,49 per month on the annual plan. Less than two minutes of human transcription per month, for unlimited use.
Quick comparison
| Model | Cost of 1 hour of audio | Turnaround | Free plan ceiling |
|---|---|---|---|
| Human freelancer | R$180 to R$900 | 24 h to 5 days | doesn’t exist |
| AI with pay-as-you-go credits | R$4,50 to R$30 | minutes | demo minutes |
| Dollar meeting app | ~R$45/month (annual, with IOF) | minutes | 120 to 300 min/month |
| Sintesy free | R$0 | seconds | 60 min/day and 10 syntheses/day |
| Sintesy Pro | R$0 (unlimited) | seconds | — |
Sintesy’s public benchmark for processing a synthesis is 9 seconds, against more than a minute for traditional notetakers — which barely changes the price, but changes a lot what you do with the result: you can review it before the next meeting starts.
How to decide in three questions
1. How much audio do you produce per day? Under an hour a day, the free plan covers the entire flow, no card required. Above that, compare subscriptions — and compare in reais, not in dollars.
2. Is the audio in Portuguese? A low price with poor accuracy on Brazilian Portuguese ends up expensive: you pay for it in manual review. Tools built for English treat a Brazilian accent, slang and technical terms as noise.
3. Do you need to take the content out of the app? Exporting to PDF or DOCX, sharing by link and listening to the synthesis as a podcast are the features that separate “I looked it up” from “I delivered it”. If the final destination is a document or a team, that’s the criterion that decides the plan.
Frequently asked questions
How much does 1 hour of transcription cost in 2026? It depends on the model: human transcription runs between R$180 and R$900 per hour of audio; AI charged by the minute, between R$4,50 and R$30; dollar subscription apps come out around R$45 to R$91 per month, covering many hours.
Is transcribing audio free? Yes, with a ceiling. Free plans exist, but each one limits you in its own way: some by minutes per month, others by the maximum size of each recording, others by the number of AI summaries. What decides whether free works is which of those three dimensions cuts first in your usage.
What is the limit of Sintesy’s free plan? Up to 60 minutes of content per day and up to 10 syntheses per day, with a preview of about 20% of the full synthesis content. Export, link sharing, podcast and WhatsApp are Pro features.
Do I need a credit card to try it? No. The free plan doesn’t ask for a card — you create the account, upload your audio and see the real result on your own material before deciding on any subscription.
Is it better to pay per minute or by subscription? If your volume is sporadic, paying per minute avoids a subscription sitting idle. If you transcribe every week, the subscription diluted in reais ends up cheaper per hour than almost any pay-as-you-go credits.
What to do with this bill
The right question isn’t “how much does audio transcription cost”, it’s “how much does transcribing MY audio cost, at MY volume, with MY output needs”. An hour a day on the free plan solves it for anyone recording meetings and classes; exporting and sharing requires Pro; minutes with formal validity remain human work.
Test it with the hardest audio you have — a meeting with several people, a phone recording in the middle of noise. If the transcription holds up in that case on the free plan, you already know what you’ll pay for the rest: nothing, or R$12,49 per month.
Stop taking notes. Start understanding.
