Nibbler turns the books you mean to read into five-minute daily lessons — then spaced repetition keeps them fresh.
Set it up once. After that, a fresh lesson arrives every day at the time you pick.
A friendly 5-minute chat. Tell Nibbler your goals, what you're working on, and how you like to learn — it builds your growth profile from there.
Drop in PDFs, paste a URL, or add plain text. Pick Wisdom Mode for personalized insights, or Story Mode to read a book in order — one section per day.
At your chosen time, a personalized lesson from your own content lands — tuned to your goals, in the read length you prefer (5, 10, or 15 minutes).
Every bite comes with a reflection question and a daily prompt — a task, a challenge, or an action to try. Quiz yourself and chat directly with your books.
A focused set of tools built around your content, your goals, and your time.
One sharp insight delivered every day, at exactly the time you choose. Nibbler pulls it straight from your own uploads — a book you bought, an article you saved, or a PDF you never got around to finishing. Short enough to read between your alarm and your morning coffee. Deep enough to actually matter.
Wisdom Mode distils the most impactful ideas from your uploads based on your growth profile and brings them to the surface exactly when you are ready to learn.
Story Mode works through fiction and biographies in sequence — one passage at a time — so the narrative always flows naturally and nothing ever feels out of context.
Every lesson ends with a reflection prompt and a short quiz — not a pop quiz, but a genuine check on whether the idea has actually landed. Over time, Nibbler resurfaces the concepts you found most challenging, so nothing slips through the cracks and everything you read becomes something you truly remember.
Have a real conversation with any book in your library. Ask about a concept, dig deeper into an idea that resonated, or get a plain-English explanation of any chapter. Nibbler draws its answers only from what you uploaded — every response is grounded in your own content, never the open internet.
See what it feels like when your reading actually sticks.
