I really wanted to love Alter. It’s tackling a genuinely unique and valuable use case, and I can absolutely see it being the perfect fit for certain workflows.

In my case, I’ve already solved much of this functionality using Claude Code, so it may simply be that I’ve moved past where Alter would have been most helpful. I also ran into some performance issues on both my MacBook and Mac Mini, where it seemed to use a significant amount of CPU/GPU—though that may be specific to my setup rather than the app itself. It might be the AppSumo version of the tool as I didn't see any mention of this in the forums for Alter.

I’m a big fan of the developer and what they’re building here. While it wasn’t the right fit for me, I think this will be a great tool for the right user.
