So where did the idea actually start?

00:00:07

Honestly, in a car park. I recorded voice notes between meetings and never listened to them again.

00:00:15

And now?

00:00:16

Now I read them. It takes about a minute.

How to transcribe a file with Kotosay

What happens when you transcribe a recording

To transcribe a recording is to write down what was said. On Kotosay it is AI transcription. Your recording goes to secure servers, the speech is turned into text, and the transcript opens in your browser with a timestamp on each line.

Everything runs on the website, in any browser, with nothing to install. Audio and video both work. With a video, your browser pulls out the sound and compresses it first, so even a large screen recording usually sends only a small audio file.

90+ languages, detected for you

Leave the language on automatic and Kotosay detects it before it transcribes the file. If you already know it, or the file opens with a minute of music, pick the language from the list before you upload.

Kotosay works in 90+ languages, from English and Spanish to Arabic and Japanese.

What you can do before you pay

Your first file needs no account and shows its first 5 minutes in full, enough to judge your own recording before you share an email address.

  • A free account transcribes 3 files a day.
  • Each free file shows its first 5 minutes. A longer file still uploads, and the rest stays locked until you open it with Single file or Unlimited.
  • The editor is free on every plan, even on your first file without an account.
  • Exports and translation come with Single file and Unlimited.

Unlimited pricing and what it adds

Unlimited costs $9.99 a month, or $119 if you pay once a year. It suits people who transcribe every week or work with long files, such as full lectures, webinars or podcast episodes.

  • Files up to 10 hours long
  • 3 files processing at the same time
  • Use on up to 3 devices
  • TXT, DOCX, PDF, SRT and VTT downloads
  • Translation that keeps every timestamp

TipYou can cancel in one click from your account. Your renewal date is in your account at any time, so you can decide in good time.

AI or human transcription

AI transcription costs far less than a typist and runs at any hour, weekends included. It fits interviews, lectures, meetings and voice memos, and you can fix any word yourself in the editor.

A human transcription service has a person type out the recording. People choose it for court records and similar work where every line has to be signed off. With AI text, check names and numbers against your own recording before you publish.

What decides the quality of a transcript

The recording matters most. One speaker close to the microphone in a quiet room is transcribed cleanly. Music under the voice, people talking over each other and a phone at the far end of a table all cost words.

TipUse the free first 5 minutes as a test. If they read well, the rest of the same recording usually will too.

Your file and your payment

We delete your audio file automatically 24 hours after transcribing it. Your transcript stays until you remove it. Delete a single file, delete the whole account, or ask support to delete your data for you.

Payments for Unlimited go through a secure checkout. If a file fails or something looks wrong, write to support. We answer within 24 hours.

Questions

How do I transcribe audio and video to text?

Upload the file at the top of this page and Kotosay transcribes it. The language is detected for you, and the text opens in an editor with timestamps. Without an account you see the first 5 minutes, and a free account shows the first 5 minutes of 3 files a day.

Can I transcribe for free first?

Yes. Your first file needs no account, and its first 5 minutes show in full. A free account then gives you 3 files a day, with the first 5 minutes of each one transcribed. You can read, edit and copy the text on both, and you never need a card for that.

How long can a file be?

Unlimited takes files up to 10 hours and works on 3 at once. Single file opens one file of up to 10 hours for $4.99, paid once. On a free account a long file still uploads, and its first 5 minutes are transcribed, so you can judge the beginning before you pay.

Which languages can be transcribed?

Kotosay transcribes 90+ languages. The language is detected automatically, and you can also pick it from the list before you upload. English, Spanish, Portuguese, French, German, Turkish, Arabic and Japanese all work the same way, as do recordings from smaller languages in the list.

How accurate is AI transcription?

On a clear recording it comes out clean, and the editor lets you fix the words that do not. Background music, crosstalk and a speaker far from the microphone cost words. Your first 5 minutes are free, so you can judge the result on your own file. Check names and numbers before you publish.

Can I export to Word, PDF, SRT or VTT?

With Unlimited you can. Downloads come as TXT, DOCX, PDF, SRT and VTT. DOCX opens in Word and Google Docs, and SRT and VTT work as subtitle files in YouTube Studio and most video editors. On the free plan, copy the text straight from the editor instead.

Does the transcript come in separate timed lines?

Yes. The transcript comes as separate lines, each starting with its timestamp, so you can find any passage in your own recording. Fix a word in the editor and the timestamps stay in place. With Unlimited, SRT and VTT exports keep the start and end time of every line.

Is my file kept after transcription?

We delete your audio file automatically 24 hours after transcribing it, and your transcript stays until you delete it. You can remove a single file, delete your whole account or ask us to delete your data. Files you only convert with MP4 to MP3 or the audio converter stay on your device the whole time.

What is the difference between AI and human transcription?

AI transcription costs much less than a person typing and is ready at any hour, and you fix words yourself in the editor. A human service has a person type the recording, which people choose for court and similar records. Kotosay is AI transcription, so read names and numbers against your own recording before you publish the text.

Do I need to install an app?

Kotosay runs in the browser on your phone or computer, so there is nothing to install. Open the site, upload a file and read the transcript there, or start on your phone and finish on your laptop later. An Unlimited plan works on up to 3 devices.

How much does Unlimited cost?

Unlimited is $9.99 a month, or $119 if you pay once a year. Payment runs through a secure checkout. Every payment comes with a receipt, and your renewal date is in your account at any time, so every charge is easy to follow.

How do I cancel Unlimited?

Open your account and cancel in one click. You can do it at any time, from any of your devices, with no form to fill in. If something about your plan or a payment is unclear, write to support and we answer within 24 hours.

Does Kotosay label speakers or play back the audio?

No. Each transcribed file becomes a list of timed lines without speaker names, and the page has no audio player. Type a name in front of any line in the editor if you need one. To hear a passage again, open your own recording at the timestamp shown next to the line.
