BookAI.chat is a solo project, credited on its homepage to @markdoppler_, that lets a reader discuss a book by typing its title and author, with no file upload and no need to own a copy. A short library of sample titles, from 1984 to Clean Code and Pride and Prejudice, shows the format: the chat opens with shortcut prompts for a summary, the main idea, or an explanation of the ending, then continues as an open conversation. The site advertises support for more than 30 languages, so a reader can discuss a book in their own language or one they are learning, and lets a cover image be added when a new title is entered. The free tier runs on GPT-3.5, with a GPT-4 option marked PRO in the model picker.
The tool never reads the actual book: it works from the title and author alone and lets the underlying model’s own training answer questions, rather than searching the real text. That means it can discuss well-known books reasonably well, but it can also state a wrong plot detail, invent a quote, or discuss a book it barely knows about with the same confidence as one it knows well, and there is no way from the chat alone to tell which is happening. Treat anything specific, such as a quote, a page reference or a plot detail, as unverified until checked against the book itself, and do not rely on it for schoolwork or citations. No pricing page or terms link was found, and the PRO, GPT-4 option carries no stated price.
Chatting is free, with no account required to try the sample titles. A GPT-4 option is marked PRO in the model picker, but no price for it appears anywhere on the site.
