# View Diff History
Quickly track the changes in your project locally. Allowing you to have all the advantages of git version control on remote files.
Along with every change, BLACKBOX AI will generate a brief description you can use to have a better understanding of the evolution of your project.
**How is this helpful?**
> Easily rollback your broken code to a working state
> Debug your project using the history & descriptions to track the error
> Review previous code that was done.
To use it, you can just have to open the file you want to compare click on the “View Diff” button on the BLACKBOX AI menu.
