Writing Coach teaches craft without ghost-writing. Brainstorm Agent files ideas into notes. Archive Agent tracks continuity and auto-links your world. Beta Reader leaves margin reactions. Your model, your keys, on-device.

The Archive Agent builds a professional story timeline from your notes and scenes, then flags continuity problems. Progress, Spreadsheet, Relationships, and Subway views — always in sync with the draft.

Type a character or place name and it becomes a live [[wiki-link]] — no AI needed. Every note connects into a glowing, force-directed Vault Graph, with hover previews and one-click continuity fixes.
Every theme drives the same six roles — left panel, wiki-links, agents, warm data, cool data, window frame — so one palette change ripples through borders, glows, chips, graph nodes, and the frame.
Active theme: Neon Classic
