What is Mictoo?
Mictoo transcribes audio and video to text in the browser using Whisper large-v3, with no signup for files up to 25 MB. Free accounts get larger files, daily history, AI summaries, translation and TXT, DOCX, PDF or SRT exports.
Mictoo is a browser-based transcription service that turns audio and video files into editable text without requiring an account. Drop an MP3, MP4, WAV, M4A, OGG, WEBM, FLAC, ACC, MOV or MPEG file onto the page and the site streams it to OpenAI's Whisper large-v3 model, served through Groq with OpenAI's API as an automatic fallback. That is the same speech recognition engine behind ChatGPT's voice features, and the site claims typical accuracy above 95% on clean recordings. Automatic punctuation is applied, and video files have their audio track extracted server-side before processing. Anonymous visitors can process files up to 25 MB and 30 minutes. A free sign-in raises the ceiling to 60 MB per file, and recordings up to 180 MB are split into chunks and reassembled into one transcript. Signed-in users also get 7 transcriptions per day, full history, AI summaries generated with OpenAI GPT-4o-mini, translation into 28 languages, and a chat mode for querying the transcript. Language detection is automatic across more than 50 languages, or it can be set manually in the upload form. Finished transcripts can be edited in the browser and exported as TXT, DOCX, PDF or SRT, which makes the tool useful for caption work as well as plain text. The audience is broad: students working through lectures, podcasters mining episodes for show notes, journalists checking quotes from interviews, teams documenting meetings, and creators who need subtitle files. The workflow is deliberately shallow, with no editor timeline or project management layer, so it competes on speed and cost rather than production features. According to the site, a 30-minute file typically finishes in about a minute. Speed is not guaranteed, however. Mictoo runs on a finite daily transcription budget, so when capacity runs out new uploads wait in a queue that shows position and estimated wait. Signing in does not bypass the queue. Files are not stored on Mictoo's servers, and neither provider trains on API audio.
How do you use Mictoo?
1Choose the right transcription page
Start from the audio-to-text or video-to-text page depending on your file. Each page carries format shortcuts so you land on the correct uploader.
2Set the language or leave auto-detect on
In the upload form, keep auto-detect for mixed or unknown material, or pick a specific language from the list if you want to avoid misdetection on short clips.3Upload your file and wait
Drag the file onto the drop zone or browse for it. Files up to 25 MB start without an account. If the daily budget is spent, the page shows your queue position and estimated wait.4Sign in for larger or longer files
A free account raises the per-file limit to 60 MB, enables automatic splitting for files up to 180 MB, and unlocks history, AI summary, translation and transcript chat.
5Edit, summarize and export
Review the transcript in the browser, correct mistakes, generate a summary with GPT-4o-mini, translate into one of 28 languages, then download as TXT, DOCX, PDF or SRT.6Handle oversized recordings
If a file exceeds the size limits, the site links to guides on compressing audio and splitting long recordings so the parts fit within the permitted upload size.
