Stop typing your notes. Speak them. Notas turns messy, half-formed thoughts into clean, titled notes that are easy to scan later. Just talk to your phone or Apple Watch. The AI listens and writes everything for you: a clear title, a short summary, and the to-dos it finds inside your words. Every feature is free. No ads, no subscriptions, no “unlock with Plus.” SPEAK IT. NOTAS WRITES IT. Dictate a rambling thought and get back something you would actually want to read. Notas cleans up your dictation, adds a proper title, and pulls out action items like calls, deadlines, and tasks. Speak naturally in your own language and Notas determines which language you’re using. YOUR NOTES ORGANIZE THEMSELVES Notes automatically stay organized as you capture them. Meetings, ideas, to-dos, shopping lists, and journal entries all sort without you choosing folders, adding tags, or tidying later. It stays organized for you from the start. ASK YOUR NOTES ANYTHING Got a question like “What did I decide about the beta?” or “What’s on my shopping list?” Notas answers using your own notes and shows you the note it used, so you can verify the source. It does not guess. If it’s not in your notes, it tells you. FIND ANYTHING BY MEANING Search the way you think, not the way you typed. Looking for “grocery list” can surface notes like “milk, eggs, coffee beans” even if those exact words aren’t in your search. REMINDERS IT FINDS FOR YOU Say what you mean, and Notas handles the rest. For example: “Call the dentist Thursday at 10.” If it detects a to-do, it offers to remind you at the right moment. No setup required. CAPTURE FROM YOUR WRIST Raise your Apple Watch, speak, and you’re done. Your note appears on your iPhone before you put your arm down. PRIVATE MODE RUNS ON YOUR PHONE Turn on “On this phone” and Notas runs entirely on your device. No connection needed, and your notes never leave your phone. Your voice is transcribed on-device in this mode. WORKS THE WAY YOU DO - Type or talk, whichever is faster right now - Dark by design, easy on the eyes - Sync across devices with iCloud - English, Spanish, Turkish, and Arabic, including full right-to-left support Notas is a notebook that keeps itself tidy. Capture the thought; let the AI handle the rest.
