Questions

No. Every answer is bounded by the page you have reached. Ask about the ending and Graspium says it cannot go there yet, then offers what it can talk about instead.

No. The demo at the top of this page runs on public-domain classics. Pick one and ask away. Sign in with Google when you want to read your own books.

Any EPUB without copy protection. Upload the file, or connect your tolino account and let Graspium import your books. Books with a hard lock are skipped, never opened.

Yes. Connect the tolino account of your shop (Thalia, Hugendubel, Osiander, bücher.de and the other tolino shops) and Graspium imports your open books together with your highlights and reading positions, and keeps them in sync.

A Kobo connection is in the works. Until then you can upload any Kobo book the store lets you download as a DRM-free EPUB. Kindle books stay inside Amazon's apps, so Graspium cannot reach them.

Yes. Graspium has its own EPUB reader. Select a sentence, ask about that sentence, keep reading. The question never leaves the page.

Yes. Graspium runs in the browser, and your library, highlights and reading position belong to your account. Stop on one device and continue on another.

No. Your books are never shared with other users and never used to train AI models. To answer a question, Graspium sends only the passages that matter to our AI providers, and they do not train on them either.
