m3 Mind Mapper

m3 - Mind Mapper is a mind mapping program originally intended to be used in web browsers, and thus is compatible with multiple platforms (Windows, macOS, Android, iOS, Linux, etc). That version could read and write moderately complicated Freeplane mind maps, however the architecture wasn't scalable (this was my first app using web technology 😄), and it became clear that the risk of deleting your mind maps (since they reside "within" the web browser) was too great.

A new version of m3 is being developed which will address the above shortcomings and more; here's a demo. It's very much a work-in-progress at this point, things may change (including the file format, which could make your data unretrievable), and will not work offline.

In the mean time, you can still use the older version described below.

Important Things to Know

• m3 stores your mind maps in your browser's offline storage. If you delete that, your maps will be gone. So don't do that 😃
• If you have already used m3, it doesn't update to the next version until you load the page twice, due to a quirk of a technology called app cache
