About Mictoo

Mictoo is a free audio and video transcription tool. Upload a file or paste a YouTube link, get the text with timestamps, then summarize, translate or download it.

I built Mictoo because decent transcription should not need a subscription or technical skill. You can use it without an account; a free account adds longer files, History and chat.

Who built Mictoo

My name is Denis and I build and run Mictoo on my own. There is no team behind this, no investors, and no growth target. I have spent the past decade working on SEO, content and developer tools, and I built Mictoo because every transcription tool I tried was either gated behind a signup, slow, or annoying enough that I gave up halfway.

Running it alone shapes what the site is. Features ship when one person has time, and nothing here exists to satisfy a roadmap. It also means the email at the bottom of this page goes straight to my inbox rather than a ticketing system. I read everything that lands there.

If you want to check who you are dealing with, my professional background is on LinkedIn.

What powers Mictoo

Transcription runs on OpenAI's open Whisper large-v3 model, served through Groq's US-hosted API. Whisper large-v3 was trained on about 5 million hours of audio. You can let it detect the language or pick one of 36. If Groq is busy or down, the file goes to a backup: Replicate (the same Whisper model), then Deepgram's Nova-3, then OpenAI's own Whisper API. The AI summary, translation and chat use an OpenAI model and get the text of the transcript, not the audio.

What happens to your file

Your file uploads to temporary storage (Vercel Blob), goes to the transcription provider and is deleted once the transcript is ready. An hourly cleanup removes anything left behind, so no upload stays longer than about two hours. Ten minutes of speech usually takes 15 to 30 seconds; at busy times your file waits in a queue and the page shows your position.

Without an account the transcript is not saved on my servers. It lives in your browser tab, so download it if you want to keep it. What I log is a count of files processed, to track usage and reconcile the provider bills.

With a free account, the text of your transcripts is kept in History for seven days so you can reopen them, then deleted. The audio is never kept. The Privacy Policy lists every service involved.

How Mictoo pays for itself

Right now it does not: hosting and transcription bills come out of my pocket. The plan is display ads (Google AdSense) on the content pages, never inside the tool and never between you and your transcript.

A small paid tier is also in the works, for people who need speaker labels or very long files. The free tier is not going anywhere. Most people transcribe a file every few weeks, and nobody should pay a monthly subscription for that.

I do not sell your data and do not use your files or transcripts for anything but giving you the result.

What I hold to

  • Free. No trial periods and no credit card. The free account is free too.
  • Private. Audio is deleted after transcription. Only signed-in users get a History, and it is cleared after seven days.
  • Simple. Drop a file, get the text. No setup, no editor to learn.
  • Honest. The limits, the queue and the backup providers are written down on the site, not hidden in small print.

What I will not do

  • No dark patterns. No fake countdown timers, no "your file expires in 60 seconds, pay to download", no email walls in the middle of the upload flow.
  • No bait-and-switch pricing. The free tier is genuinely free. I will not retroactively gate something that used to be free.
  • No transcript reselling. Your transcripts are not sold or licensed, and there is no "training data" clause tucked into the terms.
  • No deceptive ad networks. Google AdSense only, never the networks that swap out your browser UI or hijack the back button.
  • No fake reviews. If you see Mictoo on a review site, it got there organically. I do not pay for placement and I do not write my own reviews.
