Think in plain Markdown.

Everything a knowledge base should be

Powerful where it counts, and out of your way everywhere else.

📄

Local-first, plain files

Your notes are ordinary .md files in a folder you choose. No database, no lock-in, readable in any editor — and still yours if you ever stop using HelloNotes.

✍️

A native live editor

Built on TextKit 2, not a browser engine. Markdown styles as you type, with syntax-highlighted code, LaTeX maths, Mermaid diagrams and collapsible callouts rendered natively.

🔗

Connected thinking

[[Wiki-links]] with autocomplete and aliases, backlinks, unlinked mentions, note transclusion, and an interactive graph of how everything relates.

🔎

Find anything, fast

Full-text search with snippets, Open Quickly, nested tags with autocomplete, bookmarks, daily notes and templates.

✨

Intelligence on your device

Summarise, suggest tags and links, find the links you meant to make, or ask questions across your whole library — on-device with Apple Intelligence, or your own model if you prefer.

🕘

Version history with Git

Initialise a repository, commit as you write, browse any note’s history and restore an earlier version. Sync to your own remote — never to us.

Private by design

HelloNotes collects nothing. There is no account, no analytics and no tracking, and we operate no server that could receive your notes. On-device AI runs locally and never sends your writing anywhere.
