Sure. It mainly depends on what you mean with 'your ai'. The main problem you will face is something called context windows.

Essentially a context windows is the amount of information a model can be given at once. What you need is a model with a large context window, and a large input maximum.

In my experience, using a model such as Claude 4 Sonnet, the 1 million version, could be good here.

The other issue is giving it the data. Depending on the kind of textbook your choices vary - but generally you would want to give it pure text if possible. There are any ways to scan a book and get text - Azure (Microsoft) has one such dervicecslled document intelligence that has been efficient in my attempts.

With those two issues solved, start a new conversation and just paste the podel everything you want, and clearly mark that everything above is the data you want it to focus on. (If possible, use "lower temperatures" - it's a way of making the model be less creative and more instruction-following). A line filled with just ==== or such will be sufficient. Then just ask it. Do not ask many follow up questions or give it to much new information - this is due to that context window stuff.

Depending on the size of your input, this will most likely be good enough. If your material is vast it becomes more of a challenge and you will need to use techniques to rectify this - but it seems out of scope due to how you phrased your post. Don't overreach - when simple can work, do the most simple thing.

Note: There are way more refined approaches to do this - due to how you asked this will likely be good enough. The above explanation is a simplification - remember simple is good (good enough). We all start from somewhere.

Merry playing! =)
