Notes that flow into layered knowledge.
Rhyolite is a local-first knowledge base for Mac, Windows, Linux, iPhone and iPad. Every note is a plain Markdown file in a folder you own.
No account. No tracking. Plain files you can open anywhere.
Knowledge settles in layers
A note is one layer. Links bind the layers together. Over time they become something you can stand on.
Write
Live Preview hides the Markdown except where you are typing. Callouts, tables, math, code and properties look finished as you write them.
Link
Type [[ to link any note, heading or block. Backlinks show where an idea already lives, and the graph shows how the whole vault connects.
Think
Lay ideas out on an infinite canvas, draw diagrams from plain text, turn properties into tables and boards, and review flashcards written inside your notes.
Solid ground for your notes
Plain files in a folder you own
A vault is an ordinary folder of Markdown. Open an existing Obsidian vault and carry on where you left off.
No account, no tracking
Rhyolite works offline and collects no data. Keep a vault in iCloud Drive to use it on your Mac, iPhone and iPad.
Ready for AI agents
A built-in MCP server lets agents search, read and edit notes within the folders you allow, and asks before anything destructive.
Rhyolite is coming soon
Downloads open at launch, and pricing will be announced then.
