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, or record one. Isy transcribes your voice and tidies it up in your own words • Brain dump: talk through everything on your mind and Isy turns each idea into its own note • Turn screenshots and photos (a whiteboard, a page, a slide) into notes • Reflect: five quick questions that draw out what's on your mind, saved in your words • Bring in what your other AI assistant already knows about you, with one prompt ISY CONNECTS IT • Every note is tagged and linked to related earlier notes, automatically • The Isy map: your Areas at a glance, sized by how many notes they hold, with lines showing how closely they connect • A living page for each topic: your position, how your ideas connect, tensions, open questions and what it means • Today's connection: one thread Isy found running across different Areas of your notes IT COMES BACK WHEN IT MATTERS • A daily digest that feels like finding an old notebook: a thought from months ago that connects to this week, and one question worth a minute over coffee • Chat with your notes: answers cite the notes they come from, with dates, and say so when your notes don't cover something • Ask anything, then tap a paragraph to save it as a note • Optional reminders for today's connection and today's 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, summary 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.
