Notis turns a screenshot into a calendar event. Someone texts you "dinner Friday 7pm," a flyer has a date, a ticket has a time, an email has a meeting — instead of retyping it, just screenshot it and share it to Notis. Notis reads the text, figures out the title, date, and time, and shows it to you to confirm before it's added to your calendar. WHY NOTIS • Fast — screenshot, share, done. • Private — text is read on your device. On supported iPhones the whole thing is on-device and nothing leaves your phone. • No accounts, no ads, no tracking, nothing to set up. • Works from the share sheet or straight from the app. GREAT FOR • Plans buried in text messages and group chats • Event flyers and posters • Concert, movie, and travel tickets • Meeting times in emails and DMs You're always shown the event to review and edit before anything is saved.
