Capture voice notes, write Markdown notes, organize bookmarks and manage to-do lists with habit tracking—all in one place. Ask Rosetta, your built-in AI assistant, to help you find and use what you’ve saved. One personal memory for your AI apps. Keep your notes, bookmarks and reminders connected, and share the context you choose with compatible AI assistants. CAPTURE IDEAS BY VOICE Dictate a thought on your iPhone or Apple Watch, or import audio, and turn it into a structured note or reminder. Keep recording while you use another app, so an idea does not have to wait. WRITE AND CONNECT MARKDOWN NOTES Write and edit Markdown with headings, images and your choice of editor font. Link directly to a note section, connect notes to reminders and saved links, and explore related notes in a visual graph. Reuse note templates with date and time variables. Export notes as Markdown or PDF. YOUR BOOKMARK MANAGER Share a link from your browser to Rosetta to keep it with your notes. Read saved links without distractions, or choose “Import page as a note” to turn a page's main text and images into an editable note. Organize your reading in a list or gallery. TO-DO LISTS AND HABIT TRACKING Create reminders, break them into subtasks and set recurring routines. Use the built-in habit tracker to follow your routines and review completed and missed occurrences in a calendar. Import Apple Reminders and connect Google Calendar or Apple Calendar to keep events alongside your notes. GIVE YOUR AI ASSISTANTS CONTEXT Ask Rosetta, the built-in AI assistant, questions about your notes. Connect compatible AI assistants through MCP (Model Context Protocol) so they can use the personal knowledge you choose to make available. Keep your context together instead of rebuilding it in each conversation. FIND WHAT YOU SAVED Organize notes, reminders and bookmarks with categories and tags. Search across your memory, choose list or gallery views for notes and links, and use Home Screen widgets for quick access. From a spoken idea to a saved article or your next task, Rosetta keeps the things you want to remember connected.
