Notist

Notist is a new AI-powered notes app that lets AI handle the writing, tidying, and organizing for you. "I can't keep up with notes." "I want to jot things down quickly, but also have them read well later." "Similar notes end up scattered everywhere." "Shopping lists, recipes and to-dos live in yet other apps." AI takes on all of it. There are three things we really want you to know. - 1. All your note work, done in one chat Creating, updating, merging, and searching notes, plus creating and organizing folders โ€” if it's note work, just ask in chat and it's done. A note can grow out of a plain conversation, or you can ask AI to research the web (say, "look up the latest AI news and save it as a note") and build the note for you. AI keeps folders organized and searchable on its own, so you never have to remember where a note lives. And whenever you'd rather fix something yourself, direct editing is always right there. One tap switches between your note list and a dedicated full-screen AI chat. You can always see what the AI is doing right now (thinking, creating a note, searching), so you never wonder whether it's stuck or working. Attach images or files, or just speak with voice input. - 2. AI runs your shopping, too Say "add milk to my shopping list" and it's built automatically. Ask for a recipe and AI adds whatever ingredients you're missing straight to the list. Optional alerts near a store or on a buy-by date make sure nothing's forgotten. Checked items move themselves to a "Purchased" list, and when you cook a saved recipe, AI deducts the ingredients you used from Purchased automatically. Recipes you make are kept, so you can build a favorites box over time โ€” and any recipe from the web can be imported, too. - 3. To-dos, handled by AI too Say "send the slides by tomorrow" or "clean the room this weekend" and AI turns it into a checklist note โ€” just tick things off when they're done. It also works with your iPhone's Calendar and Reminders: ask "add a meeting on Friday at 10" or "remind me to buy milk at 9 tomorrow" and it adds the event or reminder, always after a confirmation. When a note's deadline is coming up, AI notices and lets you know. - A few more things it does - Nested folders, as deep as you like - Search by tag, too - Voice input - Stored on-device (cloud sync when you sign in) - In AI Chat Mode while signed in, work keeps going after you close the app, with a push notification when it's done - Great for people who want to - Create notes and to-dos as easily as sending a chat message - Tidy up meeting notes to read later - Stop spending time organizing piled-up notes - Hand shopping lists, recipes, travel plans, and idea drafts to AI - Keep the feel of a simple notes app while gaining AI's benefits - Privacy Your notes are stored on your device. Data is sent to the AI only when you act. AI features ask for your explicit consent before first use. There are no ads. Core features โ€” creating and organizing notes, folders, tags, voice input โ€” are free. AI chat comes with a monthly free allowance, with Plus/Pro plans available for higher usage. With Notist, make all the time you spend organizing your thoughts a lot freer. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
