Greta is very similar to Bolt in many ways, and in some aspects I even find it superior. The quality of the responses is excellent, and the range of topics it can handle is impressive.

However, in my opinion, there are a few important features missing that would make it truly competitive:

The ability to have unlimited discussions without spending credits, like Bolt offers.

An undo button to revert to the previous version if the current output isn’t good enough.

A history feature to track and return to earlier points where the app was working well.

Adding these would make Greta not just comparable to Bolt, but clearly better in overall usability.
