Your Company Brain
Your Company Brain shouldn't start empty.
Second Brain Link bootstraps institutional memory from the exports you already have — LinkedIn Company, Google Workspace, Slack, Notion, Confluence, Jira, Salesforce, HubSpot, Zendesk, email archives, Microsoft 365, Teams — into a structured, deduplicated, privacy-clean Company Brain your agents can use on day one. Emit to GBrain, or keep it in Obsidian for the team. Runs locally; employee PII is stripped in code.

Second Brain Studio
Browse and talk to your Company Brain — right in the browser.
No setup, no plugins. Open your Company Brain in a live workspace: explore how teams, people, and accounts connect, read notes, and ask an AI that reasons over the whole graph. Runs locally — your keys and data stay on your machines.
Interactive graph
A live, force-directed graph of every employee, team, customer and deal. Filter by type or source, search, and click any node to open its note.
Talk to your brain
A built-in assistant — Claude, OpenAI, Gemini and more — that cites the notes it used. Bring your own key; calls go straight to the provider. Nothing leaves your infrastructure.
Read, edit & track
A full Markdown editor with live preview, wikilinks and backlinks, plus a computed dashboard of your network and clusters.
Second Brain Mobile · iOS & Android
The same local-first brain, in every pocket.
A native mobile app that builds a personal twin entirely on-device — the same zero-network engine that powers the Company Brain. Your people's own exports become their own private brains on their own phones: no account, no backend, nothing touching your infrastructure.
Built on-device
Exports are unpacked and transformed on the phone itself — the brain never exists anywhere else. Meeting prep and warm-path answers from the hallway, not the desk.
The graph in your hand
A native 3D graph of people, companies and topics — search it, filter it, tap into any note before you walk into the room.
Private by architecture
No account, no backend, zero telemetry. On-device AI on iPhone; on Android bring your own key — nothing for your security team to threat-model in the cloud.
On the App Store and Google Play.
The Agent Skill · Claude Code & OpenAI Codex
The engine itself — your agent builds the Company Brain.
The product that powers everything: the open-source engine, packaged as a cross-model Agent Skill. Install it once in Claude Code or OpenAI Codex and your agent knows how to turn export archives into a structured, deduplicated, privacy-clean Company Brain — on your infrastructure, with zero network calls.
Runs where your data must stay
On a laptop, an air-gapped box, or your own server — dependency-free Python, zero network calls in the core. Nothing for security to threat-model in the cloud.
Self-adapting to your exports
Formats drift across tools and versions. The skill profiles every file, writes its own mapping rules, and rescues what it doesn't recognize — nothing is lost.
Emits your format
Obsidian vault by default, GBrain repo on request — plain Markdown either way, owned by you, readable by any agent.
The same skill powers Studio's reseed and the done-for-you onboarding — install it in one step or browse the source on GitHub.
The problem
The brain is the easy part now. Filling it isn't.
A new Company Brain is empty on day one, and your institutional knowledge is trapped in exports, shared drives, and old accounts. New hires re-learn what the company already knew. When someone leaves, the context leaves with them.

Institutional memory that survives turnover — the context stays when people move on.
How it works
Point it at your exports. Get a connected Company Brain.
- 01
Detect
Point it at a folder of team exports — Workspace, Slack, Notion, Jira, Salesforce, HubSpot, LinkedIn Company… any of the 12 company sources. It catalogs every file, locally — and if your export's format drifts from the known shape, the skill adapts its own mappings to fit it, on your machines.
- 02
Resolve
Every employee, customer, and partner becomes one identity across sources — no more four copies of Dana.
- 03
Build
An org-rooted graph: the company at the center; people, accounts, deals, and projects linked around it. No AI calls.
- 04
Emit
Emit to GBrain for the team, or keep it as an Obsidian vault. Multiple entities get a cross-entity
_correlations/brain.
Agent-ready
Institutional memory, as structured data.
Org-rooted graph
The company sits at the center — 00-org — with employees, accounts, deals, and projects as typed, linked notes around it.
Ownership is explicit
Every account knows its owner and backup. "Who has the relationship?" is a graph query, not tribal knowledge.
Cross-entity correlations
Multiple teams or entities each get a brain, plus a _correlations/ layer linking people ↔ deals ↔ teams across them.
Day-one agent context
Ships with in-brain instructions — point Claude Code or GBrain at it and it knows the schema immediately.
Works with GBrain
Bootstrap your GBrain Company Brain from data you already have.
GBrain is the brain layer — search, synthesis, team serving. We're the importer that fills it on day one, from your fragmented exports, identity-resolved and privacy-clean.
Not affiliated with the GBrain project. We emit the open-source GBrain format — we're the importer; GBrain is the brain.
Privacy-first
Your team's data never has to leave your machines.
The whole import runs locally before anything reaches a server or a shared brain — you stay the data controller throughout.
Employee PII never written
Emails and phone numbers are stripped in code at parse time — they never reach disk.
Bodies never read
Slack and mail content is never parsed. Only a frequency and recency signal survives.
HR · payroll · security quarantined
Sensitive exports are skipped by a hard-coded quarantine list — no adapter can bypass it.
You stay the data controller
Everything runs on your infrastructure before anything reaches a server. MIT-licensed — your security team can read every line.
Local-first by construction. → Read the privacy model
