The marketplace for vault-trained AI personas.
Browse curated Obsidian vaults — trained on expertise, on history, or on authored identity — and plug any of them into Claude, Cursor, or your custom agent via MCP. One endpoint. Whole-vault context. Pay per call.
Three markets. One protocol.
Every persona is an entire Obsidian vault — a knowledge graph, not a point tool. Browse, subscribe, plug in.
Job Expertise
Vaults trained on a professional domain. Query a senior practitioner with their reasoning, references, and priors. Whole-vault context on every call.
- Domain-trained on practitioner work
- Standards, case history, references
- Reasoning habits, not just facts
Historical Figures
Vaults built from the collected writings, letters, and scholarship of historical figures. Sourced and cited. Silent when the record is silent.
- Primary sources only
- Peer-reviewed scholarship
- Citations on every response
Self Personas
Authored identity vaults — fictional characters, creator personas, archetypes. Richer than a system prompt, portable across agents.
- Authored archetypes
- Creator-owned identities
- Bring your own vault (post-launch)
From vault to endpoint in three steps.
Browse a market
Preview sample queries, review the bibliography, inspect the graph structure before you commit.
Subscribe to a persona
Pay per call. No seat licenses. No minimums. Every call queries the whole vault, not a single tool surface.
Wire it into your agent
Paste the MCP endpoint into Claude Desktop, Cursor, your custom agent — anywhere MCP runs. One line, done.
Every MCP-compatible agent you already use.
Not a directory. A marketplace of minds.
Whole vaults, not point tools
Each persona is an entire Obsidian knowledge graph. Every query has access to the cross-linked context that made the answer possible — not a single tool surface.
Three curated markets
Not a firehose of 1,000+ listings. Three sharp categories — Job, Historical, Self — each vetted, each with a consistent quality bar.
Sourced, with citations
Responses include references back to the underlying vault notes. Historical vaults reply “unknown” when the record is silent, not with plausible fiction.
MCP-native from day one
Every persona is a Model Context Protocol endpoint. Works with Claude Desktop, Cursor, Windsurf, Zed, or any custom agent. No vendor lock-in.
One endpoint. Any MCP client.
Every persona you subscribe to comes back as a Model Context Protocol endpoint — paste the config into your agent and the whole vault is at its disposal.
