Speak, type, it’s noted. Turn your iPhone into a powerful idea organizer. Ideas strike, but often fade away just as fast. Traditional note apps are too slow to open or too complex to organize for capturing the moment. Jot solves this by eliminating all friction between your mind and the screen: an instant interface, no complex folders, designed for immediate capture. Jot turns your raw thoughts, voice dictations, and ideas into a perfectly structured, beautiful notebook that’s a joy to browse. CAPTURE AT the SPEED OF THOUGHT Stop worrying about which folder to file your note in. Open the app and start typing immediately in the chat-like interface. Zero complex navigation: every note is saved in under two seconds. SPEAK NATURALLY, JOT STRUCTURES THE TEXT Dictate your thoughts as they come. Powered by JOT AI, your iPhone’s new 100% local and private AI, Jot automatically cleans up stutters (like "um," repetitions, and pauses), organizes text into readable paragraphs, and generates a relevant title. Voice becomes your fastest, most fluid writing tool. ACCESS IT ANYWHERE, INSTANTLY An idea while walking or in a meeting? Trigger instant capture from the iOS Control Center, set it to your iPhone’s Action button, or simply say, "Hey Siri, capture an idea." Record your thoughts instantly without even opening the app. PLAN YOUR ACTIONS EFFORTLESSLY Don't let any idea go stagnant. Select a passage from your note to set a reminder. Jot automatically extracts dates and times from your selection (e.g., "call Peter tomorrow at 2 PM") to create custom reminders directly within the app. KEEP YOUR IDEAS IN SIGHT Never lose track. With elegant widgets designed for the Home and Lock Screens, display your most recent notes and upcoming tasks right before your eyes for one-tap access.
