You don’t need to learn all of Markdown. # at the start of a line makes a heading, - makes a bullet, and / opens a menu of tables, checklists and diagrams. Those three are all you need to keep notes that read far better than a plain notes app. What you type takes shape where you typed it, so there is no preview pane to switch to. No Google account is required — the app works with this device alone. Sign in and your notes are kept in your own Google Drive, becoming a private notebook you can pick up from Windows, Mac, iPad, iPhone or the browser. ■ Open what AI writes Ask ChatGPT, Claude, Gemini or another AI to summarize something in Markdown, then open it here as is — it reads cleanly and stays editable. It's a plain Markdown file, so you can paste it back into an AI to keep going, or drop it straight into Notion or GitHub without reformatting. ■ Ask AI (with your own API key) Add an API key for OpenAI (GPT), Anthropic (Claude) or Google (Gemini) and you can ask AI from inside the app. · On selected text — polish, shorten, make formal, translate, turn into a table or a diagram · From the whole note — meeting notes & to-dos, summarize, extract to-dos, tidy into Markdown, continue writing · In your own words — have it draft a how-to or a first version Check the answer before it goes into your note, and undo it in one step. Usage is billed by the service you choose, and your key stays on this device. ■ What people use it for · A notepad that reads better — jot things down and they turn into tidy headings and bullet points.
