Audio to Mind Map: Turn Lecture Recordings Into Study Maps

Upload a lecture recording or any audio file and Mindmapi.ai turns it into a clear, interactive mind map. Perfect for recorded lectures, seminars and voice notes.

Recording a lecture is easy. Turning that recording into something you can revise from is the hard part. Mindmapi.ai transcribes your audio and rebuilds it as a mind map of the key topics, so a long recording becomes a single, structured overview.

You can then edit the map, add notes and export it, which makes your recordings genuinely useful at revision time rather than a folder of files you never open again.

    Mindmapi.ai transcribes the audio and arranges the main points into a structured mind map.

Why students use Mindmapi.ai

Make your recordings useful

A recording you never replay adds nothing. A mind map of that recording gives you a clear overview you can actually revise from.

A long recording in one view

Mindmapi.ai condenses a long recording into a structured map, so you can see the whole session at a glance.

Edit and add your own notes

Every map is fully editable. Add topics, generate notes with AI, change colours and rearrange the layout.

Free to start

Your first mind map is free, and everything runs in your browser with nothing to install.

Frequently asked questions

How do I turn an audio recording into a mind map?

Create a new subject in Mindmapi.ai, add your audio file as a source and start the AI generation. Mindmapi.ai transcribes the recording and builds an editable mind map from it.

What audio formats are supported?

Mindmapi.ai accepts MP3 files up to 25 MB. Clear speech with little background noise produces the best transcription and the most accurate map.

How long can the recording be?

Your MP3 file can be up to 25 MB, which covers a long lecture when the audio is saved as a compressed MP3. If a recording is larger than 25 MB, export it at a lower bitrate or split it into parts.

Is it free to turn audio into a mind map?

Yes. You can create your first mind map for free. A Pro plan removes the limits if you want to make many maps.
