Local-first markdown vault

Ounie vs Obsidian

Obsidian is a beloved local-first vault: you write notes in markdown and link them by hand, with a graph view that reflects the connections you make. Ounie automates that work — it reads each source, synthesizes it into an interlinked page, builds the graph for you, and answers questions with citations. Put simply: with Obsidian you build the brain; with Ounie it builds itself.

Ounie vs Obsidian: common questions

Is Ounie an Obsidian alternative?+

For people who love the idea of an interlinked vault but don't want to build it by hand, yes. Ounie synthesizes your sources into interlinked pages and a knowledge graph automatically, then lets you ask questions with cited answers.

Does Ounie do automatic linking like Obsidian's graph?+

Ounie goes further: instead of relying on links you type, it derives the wikilinks and the knowledge graph from your sources during synthesis. You can still hand-edit any page.

Is Ounie local-first like Obsidian?+

No. Local-first, offline ownership of plain markdown is a real Obsidian strength. Ounie is hosted in the cloud so it can read your files, synthesize them, and answer from anywhere — though you can export your pages.

Can I export my Ounie brain?+

Yes. Your pages are exportable, and your brains are private by default — you choose whether to keep one private, share it publicly, or list it.

Build a second brain that cites its answers

Your first brain is free — no credit card. Upload your files, links, and notes and ask anything, with answers grounded only in your own sources.
