I Love Personal AI. It's a well developed product that has done a great job at integrating into my life. I use it every day, and it has become an invaluable resource as a second brain, autoresponder, and content creation assistant.
Not great. It is a bit difficult to understand what it is supposed to do. I didn't know what content to feed it so I started with something pretty specific about my newsletter. Then I asked it what else I should write about my newsletter and its response was like "write about your newsletter"! Not very helpful. If it actually does work, it probably requires a ton of effort on the user's part before it does something useful.
