Ghost.md is a notes app in plain Markdown with an AI assistant built in. Every note is a Markdown file on your iPhone, and the assistant can read it, write in it and plan with it while you watch. AN AI ASSISTANT, IN THE APP Ask from the dock at the head of any page. Bring your own API key, kept on this iPhone, and choose the model and how much effort it puts in. The assistant searches and reads your notes, then makes and changes them: the note opens and the words are typed in as it writes them, and the chat shows its thinking as it goes. Write requests in a note of their own and the assistant works through them. YOUR AI ASSISTANT'S OWN APP, CONNECTED With an account, connect your AI assistant's own app to Ghost.md's connector. From there the assistant can list, search, read, write and add to your notes, and you see it at work in Ghost.md, on the note it is writing. YOUR CALENDAR Sign in to your calendar, or add any calendar's subscription address. Today's events sit on the home page above your to-dos, and a query lists them or lays them on a calendar beside your to-dos. Switch it on and every to-do with a due date goes onto the calendar you signed in to, moved when its date changes and taken off when it is done. PLUGINS FOR THE TOOLS YOU USE The AI assistant, Calendar, Contacts, Webhooks and code repositories are built in, each switched on or off on one page that says plainly what it reaches. Link a note to a code repository and its list items become issues you can tick off from either side. Contacts puts a person's picture on the to-dos that name them, a tap away from a call, a text or an email. Webhooks tell a URL of yours when a note changes, and give you URLs that add to a note, for the automations you already run. THE MARKDOWN CORE Headings, lists, to-dos, tables, code, footnotes and links between notes, drawn as you type with the marks left dimmed, so a note reads the same anywhere. Seven marks of Ghost.md's own: highlight, aside, unsure, redact, shout, added, and spoiler, which sits in smoke until you tap it. Diagrams and gantt timelines are drawn from text in the note and open full screen. Add pictures from your photos or the camera. BOARDS, TICKETS AND QUERIES A list can be a board, with cards you move between columns. A note can be a ticket, with its status, assignee, priority and due date kept at its top. A query gathers notes, to-dos, tickets or events from across your library and draws them live, as a board, a table, a list, a calendar or a timeline. NOTEBOOKS, JOURNALS AND CANVASES Notes gather into a notebook with an index, to read page by page or straight through. A journal keeps an entry for each time you write, named by the minute. A canvas puts cards on a page with lines between them, saved in an open file format. WORKSPACES AND TEAMS File notes under workspaces to keep work and home apart. With an account, make an organization and invite people by their handle. It gets a workspace of its own on each member's devices. SYNC AND PRIVACY No account is needed. Without one, your notes stay on your iPhone and nothing of yours is on any server. Sign in and your notes are the same on your iPhone, on a Mac and in a browser, sealed on the device before they leave. The server cannot read them, and your password never leaves the device. The AI assistant sees only what you ask it and the notes it reads to answer, sent to your AI provider with your own key. Delete the account in Settings and everything it kept goes with it. No ads, no analytics, no tracking.
