Read the book or listen to it. Switch from where you left off. Ask the AI questions about what you're reading. Have it generate images. This isn't a store and it isn't a subscription. If you already own the ebook and the audiobook, however you got them, TomoTomo just works with the files you have. No new library to buy into, no locking your books behind another app's account, no paying Amazon a second time for something you already paid for once. What it does: Reads your own EPUB and PDF files, full screen, nothing in your way Plays your own M4B and MP3 folder audiobooks, with real lock screen controls Pairs books to their audiobooks automatically, or manually if it guesses wrong Highlights the narrated sentence as you read, with word highlighting and a reading window if you want them Finds a passage in the text and jumps your spot to it Lets you highlight and keep notes as you read Asks an AI companion about your book, with spoiler-aware catch-ups Generates illustrations from passages, and custom covers Adjustable font, spacing, and five themes, including true black Playback speed and a sleep timer, because obviously Browses free public-domain books and audiobooks Keeps your files on your device.
