# About Note Versions


HackMD periodically saves a version every 10 minutes when you're editing, so you don't have to worry about saving and can easily revert the note back to its previous state.

:sparkles: Free version users are limited to a maximum of 10 note versions, and an unlimited number for [Upgrade Prime Personal Plan or Team Plan](/@docs/Personal-Prime-subscription-management-en)!

# Note Versions Management

## Save Versions
You can save your notes manually and name it.


All previous unnamed, auto-saved versions will fold under your newly-named version.

## Edit and Delete Versions
Name and description can be changed, but the revisions (editing history) will stay.


# Compare Versions
You can compare any two versions, named or un-named. Additions from the one being compared will be marked in green while text removals in red. There's also option to filter only named versions.


# Copy Version Link
You can copy a specific version of a note and share it with others. As long as the other person has read access, they can view it.
