Write it down. Isy remembers how it connects. Type or talk: a thought on a walk, a line worth keeping, half an idea before sleep. Isy files it, links it to what you thought months ago, and brings it back when it matters. No folders. No manual links. CAPTURE IN SECONDS • Type a note, record your voice, or upload an audio file • Brain dump: talk through everything on your mind and Isy turns each idea into its own note • Turn screenshots, photos, whiteboards and slides into notes • Upload a PDF and keep the concrete ideas that belong in your notebook • Bring in what another AI assistant already knows about you with one prompt ISY CONNECTS IT • Every note is tagged and linked to related earlier notes automatically • A private feed surfaces complete, standalone connections from across your notes • Flip a card for the full read, add a follow-up thought, or continue it in Chat • Hide a connection once and Isy will not bring back that card or a close restatement • The Isy map shows your Areas at a glance and how closely they connect THINK WITH WHAT YOU KNOW • Chat with your notes: answers cite the notes they come from and say so when your notes do not cover something • Tap a paragraph in an answer to save it as a note • A daily digest resurfaces older ideas that connect to what is active now • Optional reminders for new connections and your daily digest EVERYWHERE YOU SIGN IN • Sign in with Apple or Google for a free account: the same notebook on your iPhone and on the web at isy-ai.app • Share a note, digest, connection, map or chat as a clean PDF • Export everything as Markdown at any time • Lock Isy with Face ID TWO WAYS TO USE ISY • With a free account: your notes on every device, and all of Isy's AI • Without an account: a simple notebook on your iPhone. Nothing leaves it, and there are no AI features YOUR NOTES STAY YOURS Your notes are encrypted in transit and at rest. Isy's AI runs through Isy Cloud with Google (Gemini) and Groq, and neither trains AI on your notes. Your notes are never sold and never used for ads. Delete your account any time from Settings.
