AI ToC failed , keep happening frequently

Ipad 4th 2020 12.9. Ios 18

Hello

The performance of the 4th generation iPad makes it difficult to use edge-side AI to identify blocks. Can you use the excerpt assistant feature normally?

Kind Regards,

I didn’t understand what you meant by edge-sided identification, is there a solution to generate ToC ?

Now another error keep showing , here is a photo …

Is there a page number limits?

Any update ?

Yes it can be used smoothly with no problems, but when i want to generate ToC it says Failed always!, I can’t use the function and my monthly AI points being wasted

Hello

What subject is the book you generated the table of contents for? Medicine or Biology?

It is medicine. Spine surgery

Hello

It may be because the content involves something that AI is not allowed to generate. You can try with other books, or send the PDF file where you encountered the problem.

Got it i will try sorted it out by splitting the pdf file, maybe cause the page number is 796 pages.
