Local-first company brain

The company brain that keeps every agent in its lane.

Contextful gives every teammate — and every AI agent — exactly the context they're permitted to see. No omniscient SuperAgent. No accidental leaks. Local-first, collaborative, scoped by capability.

Why Contextful

Context, with consent.

The opposite of one all-knowing agent: partial, attenuated, auditable context per person and per agent — synthesized into a brain you can actually trust.

Capability-scoped access

Agents inherit a subset of your permissions — never more. The CTO's agent can't read the CEO's salary, provably. Delegation is attenuation, not trust.

A brain that grows

Contextful ingests your tools, synthesizes context, flags anomalies, and learns from last month's mistakes — then answers questions over MCP.

Local-first & on-prem

Runs on your machine over Tailscale. Cloud is optional — used only for sync transport and LLM inference. Your context stays yours.

Real-time collaboration

Humans and agents edit the same document together as peers, with live presence — powered by CRDT sync that works offline.

How it works

Share. Delegate. Ask.

  1. 01

    Share a document

    Create a doc and invite teammates and their agents into a shared, real-time workspace.

  2. 02

    Delegate scoped access

    Grant your agent a narrow slice of your permissions. It asks for more only when it needs to.

  3. 03

    Ask the company brain

    Agents answer from synthesized context — capability-filtered, with the parts you can't see redacted.
