What Users Say
ChatGPT Reviews
Utility player AI that falls behind Claude for article creation
*Probably the best I've used at doing many tasks good to pretty well. It can do thought partnership, pivot to an image creation task, do deep research and attempt a joke to keep things light. *The Projects feature is more useful than Gemini's version, and I see that Claude added that too. Once I figured it out I created a "Temp Chat" project that I always start a session in, then I move it to a project folder that aligns. Note: these are not "folders" per se, but a central theme that subsequent chats can pull from within that Project. There is a Chrome/Edge extension that does folders nicely if you need more granular organization of your work. *The integrations with other software services work fairly well, although it's unclear how those activities use up capacity. This was a primary reason I purchased the Pro license. Like all things the other AIs are catching up, notably Claude.
