Documentation

mdai is a local-first Markdown editor for macOS, Windows and Linux. Your notes are plain .md files in a folder you choose (a vault), and every feature below reads those files rather than a database of its own.

Getting started

• Install — download and first launch, per operating system
• Your first vault — open a folder and start writing
• The editor — the live document, tabs, the outline, slash commands, Focus mode

Your vault

• Vault and files — the file tree, watching the folder, Rescan Vault
• Finding things — command palette, quick switcher, full-text search

Connecting notes

• Wikilinks and backlinks — [[link]] by name, what points back, and unlinked mentions
• Tags — every #tag in the vault, counted, with its lines

Getting things done

• Tasks — checkboxes, tags and dates across every note
• Calendar — the dated ones, laid out on the month

The rest

• AI setup (BYOK) — your own provider key, your own scope
• Export and sharing — PDF, HTML, clean Markdown
• Keyboard shortcuts — every key, and the ones that do not exist on purpose
• FAQ — pricing, trial, licenses, privacy
• Troubleshooting

Everything shipped is listed on the roadmap, and what changed in each version is on releases.
