You think. Isy connects. Together, you're unstoppable. Every “second brain” app made you the librarian — you wrote the links, maintained the graph, and hoped old ideas would resurface. Isy does that work for you. Speak or type a thought and it's automatically organized, connected to what you thought before, and distilled into living summaries of how you actually think. SUPERHUMAN MEMORY • Capture in one tap — typed or spoken. Voice memos are transcribed and cleaned up in your own phrasing • Brain dump mode: talk through everything on your mind and Isy files each idea as its own note • Nothing is ever lost: notes save instantly, intelligence happens after YOUR THINKING, SYNTHESIZED • The Isy page: a living summary per topic — your current position, in your voice — plus how your view changed, open questions, and contradictions worth a look • Every idea inside every note is connected to related earlier ideas automatically — no manual linking, no homework • A morning digest that feels like finding an old notebook: a thought from months ago that connects to this week TOOLS FOR THINKING • Reflect: five quick questions that draw out what's really on your mind, saved as notes in your own words • Chat with your own notes — answers cite your notes and dates, and say so honestly when your notes don't cover something • Ask anything, then save the best parts of any answer straight into your notebook • Import your thinking from other AI assistants with one prompt ZERO SETUP, PRIVATE BY DESIGN Isy works the moment you open it — no account, no sign-up. Your notes live in a local database on your device. AI runs through Isy Cloud with a generous free daily allowance; requests are relayed without being stored, our AI partners are configured not to train on or retain your content, and nothing is processed until you say yes.
