Your library.
Ready when you are.
Ask across books. Follow evidence. Keep context across Research, Notes, Write, Transcribe, Library, and Settings. Stay cloud-synced or local-first.
One collection. Three ways in.
Follow your curiosity.
Keep the context.
Find an answer, work through an idea, or leave yourself a note. Your reading belongs in the same conversation.
How can I make my reading more deliberate?
FROM YOUR COLLECTIONStart with a question. Notice what the text supports, write down what remains uncertain, and return to the passage when your understanding changes.
Bring a question to the page. Record what you find, and leave room for what you have yet to understand.
Original illustrative text, written for this preview.Read. Recall. Revisit.
Turn a topic into a focused study session. Work through questions, then return to the reading to fill in the gaps.
What is one question you could bring to your next chapter?
Show a sample response
“Which claim is the author making, and what evidence supports it?”
Leave a thought for later.
A good question gives me something to look for. Next time: keep the question beside the passage, then write what changed.
Linked reading: Field notesKeep typed notes and handwriting together. AI transcription depends on your configured provider.
A preview of the workflow, not a live AI session. Your actual answers depend on the sources and provider you connect.
Start with what you trust.
The bookshelf
you already own.
Opened up.
Bring in a PDF, a book, a folder of documents, or a website. Keep originals on your computer, or a local folder, and give your collection a searchable home.
Set up your libraryYour library
Search your own collection first. Follow an answer back to the passage that informed it.
Your selected sources
When outside research is enabled and no library match is found, look to the websites you have chosen.
The open internet, if you want it
An optional final step, with a configured search provider. Outside material stays labeled as outside material.
A desk. A sofa. A change of scene.
Pick up the thread.
Where you think best.
Use the Windows client at your desk and the mobile-friendly workspace on your phone. Connect to the same reachable server and sign in to keep your work tied to your account.
Try a guest workspace. Sign in when you want account-based continuity; guest workspaces do not merge.
Use an AI provider supported by your server configuration. Hosted AI needs an internet connection.

Before you settle in.
A few good
questions.
Can I keep my books on my own computer?
Yes. Originals can stay in a local folder. Leaf indexes extracted text and citation information. The Leaf host must be reachable from the client you are using.
Does everything work offline?
No. Hosted AI and outside research need internet access. Keeping original files locally does not make hosted AI offline. Your phone also needs a connection to the Leaf host.
How do citations work?
Answers link to retrieved passages. The reader preserves location information such as pages and passage anchors; matching local PDFs can show their original page. A citation helps you check the answer—it is not a guarantee that the AI interpretation is correct.
What can I download today?
The Windows Leaf installer. It installs the client; you also need a running Leaf host or a connection to an existing host. The phone experience is a web / Expo pilot, not an app-store release.
Will I have to reinstall for every update?
The installed Windows client has a check, download, and restart flow. The current pilot uses a local update feed; public release hosting is not configured yet. Compatible phone OTA updates also require a configured Expo project and native build.
Your next idea might already be on your shelf.
