Only for Mac

Mac

mdai is a calm, local-first Markdown editor. Your notes stay ordinary .md files in a folder you choose, and the AI assistant runs on your own API key — nothing is uploaded, nothing is held. PLAIN FILES, ALWAYS Open your vault in any editor, sync it with anything, keep it forever. There is no mdai account and no sync service — your files sit on your disk. AI BESIDE THE TEXT Summarize, fix grammar, translate — a section or the whole document, with a line diff you accept or reject. Your key, your provider, your call. mdai never resells tokens; add a key when you want the assistant, and delete it when you don't. TASKS FROM THE WRITING Write a task anywhere and mdai gathers them across the vault. Headings become an outline you can jump through. TODAY'S NOTE, ONE KEY AWAY Press ⇧⌘D and mdai opens a note named with today's date, started from your template if you set one. ONE PRICE, YOURS TO KEEP Try every feature free for 15 days. Then unlock mdai forever with a one-time purchase — no subscription, no account, no upsell inside the app.

mdai 1.3.7: ask before AI, tags that nest, and an Insert menu. You stay in control of what leaves your vault, your tags finally have structure, and the menus are easier to find your way around. What's new - Ask before AI: before the first request to each cloud AI provider, mdai asks for your permission and tells you which provider the text will go to. Cancel and nothing is sent. Your answer is remembered, and you can withdraw it in Settings → AI. - Nested tags: use tags like project/alpha. The Tags panel shows them as a tree you can collapse and expand, and a click on a parent tag shows the notes of its sub-tags too. - Combine tags: find notes with this tag AND that tag, or with this tag but NOT that one. - Insert menu: the insert actions that used to be spread over Format and Paragraph now live in one place, with Columns and Date. - Vault page in Settings: daily note folder and template, templates and attachments. "Create examples" adds three ready-made templates (daily, meeting, idea) without overwriting anything. - Quick capture: a second capture with the same title becomes a new note instead of touching the first one.
