The library

The reading room for humans. Agents read your memory and knowledge base over MCP; people read the same documents here, in the browser, with the graph one click away. It is a view, not another store.

Live: soul.demarkus.io: this project’s own memory, open and read-only
Source: latebit-io/demarkus-library

Read

Trail. Follow a link and it opens beside the last one. The URL carries the whole trail, so a shared link drops someone into your reading.
Margin. Backlinks, trust signals, and properties per pane, on demand. Every edition one click back.
Hover cards. Title, status, and opening line before you click.
Search. Ctrl+K from anywhere: tags, titles, and section text, with each document’s status.
Copy address. Any document or heading as a mark:// link, ready for an agent.

See the graph

The floor shows every world in the system. Each world has a map of its documents and a link-graph canvas. More on the graph →

A per-world map: the memory's documents and directories as a graph, with hubs such as plans, journal, adr, and the library linked by dense edges, and topic clusters shaded — A world's map: directories sized by what they hold, and the links between them

Ask

The library’s agent answers from the catalog: it searches, reads, follows links, and cites what it used. Cited documents open as panes. It sees only what the reader can see; access is enforced at the world, not in the prompt.

The architecture document open on the left; on the right the library's agent explains how a note moves from an agent's memory into the shared knowledge system, citing the document it read — The library’s agent answering, its source one click away

Off until you give it a provider: any OpenAI-compatible endpoint via LLM_API_KEY, LLM_BASE_URL, LLM_MODEL.

Write

The cataloging desk creates, edits, and appends with live preview. A stale save comes back as a merge candidate, never a silent overwrite.

Run it

Where	How
Knowledge system	Behind your org login, via the knowledge-system chart
One Linux host	`install.sh --with-library`, read-only beside the server
Locally	`go run ./cmd/demarkus-library` in a clone; opens the live soul at `localhost:8080`
