Exocortex reads your meetings, newsletters, and notes — builds a structured reasoning graph from them — and surfaces what matters before you know you need it.
You read 50 articles a month and remember 3. Your meeting notes are buried in a vault you never re-read. Your decisions aren't connected to the knowledge that should inform them.
Most "second brain" tools make storage easier. Exocortex makes thinking automatic.
Eight things that change how you work with your own knowledge.
Meetings (Fireflies), email (Gmail), RSS, and any Markdown file you drop in your vault arrive automatically. No copy-paste workflow.
Every fact becomes a node, and relationships are typed (causes →, contradicts →, cited_in →). Postgres + pgvector + Apache AGE.
An LLM runs nightly over the graph and regenerates your wiki from scratch: meeting summaries, client dossiers, topic deep-dives, contradiction flags.
16 MCP tools give Claude (or any MCP client) GraphRAG retrieval over your knowledge, with ranked source provenance. Not web search. Your history.
SM2 spaced repetition over the graph, weighted by current relevance instead of just temporal decay. Important things resurface on their own.
Gap Radar flags dense thought clusters with no synthesis, orphan notes, and unresolved contradictions older than 30 days.
Night Shift runs at 03:00 UTC and pushes contradictions, pattern shifts, and overdue action items to Telegram. The day starts with signal.
Check a task in Notion and every surface updates; ask a question in a Notion field and get a cited answer back. Bidirectional cockpit, no context switching.
Morning briefing — Night Shift synthesis delivered to Telegram
Notion mirror — your knowledge auto-synced to the tools you already use
MCP ask() in Claude Desktop — answers grounded in your notes
Gap Radar — weekly report of clusters missing synthesis or decisions
Manage multiple clients without losing context. Fireflies meetings auto-captured, Notion mirrored for deliverables, morning briefing in Telegram.
Consultant quickstartMCP tools in Claude Desktop. Typed reasoning edges over decisions, ADRs, and RFCs. Contradiction detection across architectural choices.
Developer quickstartResurfacing engine, overnight synthesis of papers, Gap Radar for under-explored topics, contradiction detection across sources.
Researcher quickstartDrop a file, finish a meeting, save a link. The capture API picks it up automatically. Sources: Obsidian vault, Fireflies, Gmail, RSS, Notion, anything you POST to /capture.
Every captured item becomes typed nodes and edges in a Postgres graph. Relationships are explicit: contradicts, decided_in, supersedes, cites. Synthesis runs nightly.
Nightly compilation rebuilds your wiki. Morning Telegram briefing. MCP tools for on-demand queries from Claude Desktop. Gap Radar for weekly nudges.
