Nice interface, but no good at PDF answers, especially tables data.

The maximum number of pdf pages for the free tier is 10, which is a bit small. Generally, I think people need this service for pdf documents over 50 pages or so.

There is no way to tell how good this AI Text to MP3 service is without paying up front. Maybe it's good, maybe it's not.

I like it. It answers simple questions accurately and by the book. The Ref (reference) page is not usually accurate though. I'll keep you updated on how it responds to complex questions.
