What users say
Pros
- Free tier covers real jobs such as building a website or drafting legal letters.
- Summarizes website information and gives straight answers faster than browsing a stack of sites.
- Finds answers inside a mailbox, OneDrive and SharePoint files in Microsoft 365.
Cons
- Daily message caps stop work after a handful of prompts, including on the free tier.
- Confidently returns wrong facts and keeps defending them after being corrected.
- Repeats the same answer and needs the same instruction given many times.
- Uploaded files and past chats disappear, so documents have to be uploaded again and again.
- Image generation outputs odd pictures and misspells any words requested on the image.
- The Word, Excel and PowerPoint add-ins produce output that has to be redone by hand.
