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.

Some things stay with you. The image you stop for. The idea you come back to. Stellata is where they go. Tap Share in any app — Instagram, TikTok, X, YouTube, Pinterest, a blog, anything — and the picture, the words and the video come across with the link. Screenshots, photos, videos and PDFs come in too, no link needed. Then it starts to sort itself. ALIKE SAVES DRIFT TOGETHER Every link is read on your phone: its words, and what its picture shows. Nothing is sent anywhere. Tags appear on their own, and saves that belong together drift into groups in the galaxy, so even from far off you can see what your saving is really about. The same links gather into themes you can filter by — branding, motion, space, whatever you turn out to be into. EIGHT WAYS TO LOOK Grid — everything you saved, at a glance, image first. Pinch to see more or less at once. Board — your saves spread over one plane, like a wall. Drag to roam, pinch to zoom. Wall — your pictures in columns that go on forever, whichever way you go. Leave it be, and it drifts on its own. Galaxy — your library as a world in space, alike saves floating together in groups. Tap a link and a light travels out through everything it connects to, by picture, by meaning, by tag, through its own group and across to the others. Follow it somewhere unexpected. Sort it by color, by time, by site or by style, or place words of your own, and the links they're about gather around them. Globe — step inside the galaxy, your saves all around you, above and below. Drag to look around. Earth — your saves light up where in the world they are. Timeline — every save on one line, newest first, opening out as you scroll back through the days. Projects — a space for a trip, a piece of work, or whatever you're into this week, each with a moodboard to lay out by hand: move, pinch and twist the pictures, then draw, write and join them with arrows. Send one out as a lookbook, a PDF of every save. Hold a finger still and draw a loop in the galaxy or on a board, and everything inside is picked, ready to move, share or delete together. SIT DOWN WITH A FRIEND Put two phones side by side and your libraries become one galaxy, each in its own color. See where your tastes meet, pass a link across, and leave with a little of theirs. The phones talk to each other directly — nothing goes through a server, and only what you choose to bring ever leaves your phone. BRING WHAT YOU ALREADY SAVED Your Instagram saves come across, and your Pinterest boards and Are.na channels too, so you start with your real collection instead of an empty page, and watch it sort itself into groups. FIND YOUR WAY BACK Type what you're looking for, or tap + to pick a color, a style or a photo, and the saves that fit fly in close. Or describe what a picture shows, like “cracked ice,” and Search finds it, even when no title or tag says so. It reads the words in your pictures too, so a screenshot turns up by what it says. Point the camera at a poster or a wall to see the saves that look most like it. Filter by site, by type, by color. Or just wander. ON YOUR MAC TOO Stellata is on the Mac as well, your library kept in step by iCloud, and Stellata Unlimited comes along. IT STAYS YOURS Everything syncs through your own iCloud, and previews are kept on the phone, so your library is there with no signal. Share a project and a few people can save into it together, on one moodboard. No account to make, no feed, no one else's algorithm. STELLATA UNLIMITED The free plan holds 30 links. Unlimited holds any number, as a monthly subscription or a one-time purchase. If Unlimited ends, nothing is deleted: your newest 30 stay open and the rest wait for you.
