Transcribe audio and video online

What do you need to transcribe?
The same uploader handles all of it - these are the recordings teams bring us most often. Two come with step-by-step guides.
Lectures & webinars
Multi-hour talks fit in one 2 GB upload - transcript, summary, and key points instead of hours of re-listening.
Podcasts
Episode audio becomes show notes, quotes, and a searchable archive of everything your guests said.
Phone & sales calls
Call recordings become transcripts with speaker labels - decisions and commitments land in writing.
How it works
Three steps from a file to a document you can act on.
Upload your recording
Drag in MP3, M4A, WAV, OGG, OPUS, MP4, or WebM - up to 2 GB per file. Works from the browser, nothing to install.
The strongest model for your language
We benchmark speech models per language and route your audio to the winner - including recordings that switch languages mid-sentence.
Transcript, summary, action items
Speaker-labeled text with timestamps, a concise summary, and a to-do list - every point links back to the second it was said.
What you get back
A structured document - not a wall of text.
Transcript with speakers and timestamps
Every segment carries who said it and when - jump from any line straight to the audio.
Summary with provenance
Decisions and action items pulled out, each linked to the exact moment in the recording, so every claim is checkable.
A growing knowledge base
Transcripts land in one searchable workspace - ask questions across every meeting and memo you have uploaded.
Supports MP3, M4A, WAV, OGG, OPUS, MP4, WebM and more - files up to 2 GB, so multi-hour recordings fit.
Supported formats and limits
If a device or platform produced it, chances are it uploads as is.

Built for real recordings, not clip-length demos
Typical free transcription tools meter minutes per month or cap files at half an hour. IronMemo is set up the other way around.
2 GB
per file
Multi-hour audio or video uploads as one file - no splitting, no re-stitching transcripts.
30+
languages
Each language is routed to the strongest speech model, and mid-sentence switches are handled.
0
minute caps on free
Upload the whole recording - the free plan does not meter transcription minutes.
