You saved it for a reason. Nemos finds it when you need it. A link from a friend. A screenshot with a door code. A thought recorded on a walk. A PDF you meant to read. Nemos keeps them in one private library and gives them back the moment you search, so you never have to remember which app you used. FIND WHAT YOU SAVED One search runs across links, the text inside your screenshots, notes, voice transcripts and documents at once. Look for “boarding pass” and the screenshot surfaces, even though you never tagged or filed it. Search is in Spotlight too, so you can start from the Home Screen. SAVE FROM ANY APP Share to Nemos from Safari, Instagram, TikTok, Messages, Mail — anything with a share sheet. Links arrive with a real preview instead of a bare URL, and articles stay readable when you're offline. Nemos also keeps what you copy, so a code or an address from two hours ago is still there. SCREENSHOTS THAT COME BACK Every screenshot is read on your iPhone, so the words inside it become searchable. Keep screenshots in folders, or let smart folders sort them for you: everything from a trip, every receipt, every recipe. NOTES, DOCUMENTS AND FILES Write notes with images, links and checklists. Import PDFs, documents, spreadsheets and ebooks: they open without leaving the app and are searchable by what's inside them. Keep files in folders and tags, next to the notes they belong with. TASKS, TO-DOS AND ROUTINES Turn anything you save into a task with a reminder. Keep a to-do list with subtasks, then schedule, snooze and check off each item. Build routines for the things you do every day, with the steps, times and notifications you choose, and attach the recipe, note or screenshot a step needs. Reminders and routines appear on the Lock Screen and in the Dynamic Island while they run. EVERYDAY ORGANIZATION FOR ADHD If you have ADHD and want help keeping track of plans and saved information, Nemos keeps the next step and what it needs in one place. Capture the thought, choose when to come back to it, and find it again with one search. RECORD AND TRANSCRIBE Record a voice note and Nemos writes it down: on your iPhone, or in the cloud for long and multi-speaker recordings. Start from Control Center or your watch face and follow it in the Dynamic Island. PLACES Save a restaurant, a shop, a viewpoint. They land on a map, so “that coffee place near the park” is a glance instead of a scroll through old messages. ASK YOUR OWN LIBRARY Ask a question and Nemos answers from what you've saved, quoting the note, screenshot or link it came from. SHARE A FOLDER Invite someone into a folder and you both watch it fill up: a trip, a project, a reading list. You decide who can add and who can only look. ON IPHONE, IPAD AND APPLE WATCH Your library syncs through iCloud, so what you save on the phone is already on the iPad. One tap on the watch complication starts a voice note, and your next reminder and running routine sit beside it. Widgets, Shortcuts and Siri reach the rest. On a computer, the Nemos browser extension for Chrome, Safari and Firefox saves links and articles to the same library. PRIVATE BY DEFAULT Screenshot text recognition runs on your iPhone, and so does the writing model on devices that support it. Your library lives in your own iCloud account, not on our servers. The assistant only uses a cloud model if you turn that on. Long or multi-speaker recordings are transcribed in the cloud for accuracy, unless you turn on “Transcribe on this device” in Settings. NEMOS PRO Unlimited recording, unlimited active reminders, smart folders, more cloud transcription and the full assistant. The app shows plans, prices and any trial you're eligible for before you subscribe. Questions or ideas: nemos@brainchild-co.com
