Search and the graph work with no AI setup at all.

One evening of exam prep: your notes sort themselves into topics, you hand one to the agent, and it drafts your revision section — finding the note you'd forgotten, and asking before it saves anything.
Topics are worked out from how your notes actually relate — no folders to maintain, no tags to remember. This one is yours to play with.
Drag the slider: the same notes, gathered into fewer big topics or split into smaller ones. The wand hides the topics — the chevrons fold each one to a single point.
Related notes are grouped and colour-coded, with an outline drawn around each topic. Nothing to set up — it reads the links and the writing itself.
Circle a topic and the graph rebuilds around just those notes — finer topics appear inside it. Watch it happen in the demo above.
Ask once and each topic gets a name from what's in it. Names are remembered, so it doesn't re-do work it has already done.
Collapse every topic to a single point when you want the whole vault at a glance, then open the one you care about.
Start with the words you'd expect. When those aren't the words you used, one press searches by meaning instead — and either way, the search can turn straight into a question for the agent.
It reads your notes before it answers, and it asks before it writes — the draft in the demo above is waiting on exactly that.
Opt in and it keeps working notes on your projects — real notes in your vault, and never a stale copy of them.
It comes knowing how to explore your vault, edit notes and search the web. Teach it more by writing plain notes.
Hook up outside tools and sources (via MCP) when you want the agent to reach beyond your vault.
Every conversation is saved in your vault. Rewrite a question and the old thread stays — nothing is lost.
It also reads images and PDFs, hands focused jobs to helper agents with their own instructions, and runs as many chats side by side as you like.
Pick where the AI runs. The answer changes what it can ever see.
