Overview

Linzumi is the chat your engineering team uses to direct dozens of AI coding agents.

Kick off work, review it, ship it. All from chat.

See every agent's work. Unblock the agents that need you from your laptop, your phone, the coffee line. Your teammates see it too.

Every decision your team makes compiles into a source of truth - what to build, why it changed, how your agents should act. That same source generates new work and verifies completed work.

Deliberative alignment, repurposed from aligning LLMs to aligning companies.
