Who We Are

Engineers and builders who've lived the pain of navigating AI-assisted work. We've shipped AI products at scale, led technical communications at major tech companies, and experienced the frustration of AI development with inadequate tools.

So we built the fix.

We believe

Documentation is Core Infrastructure

Context Belongs in Git, Not SaaS

AI Needs Understanding, Not Just Speed

Living Documentation is the Key to Context Engineering

Every other tool stores context in the cloud. We store it in Git. That's not a feature difference. It's architectural.

And it means we eliminate third-party tool complexity while making context version-controlled and agent-accessible.

Perfect for:

Solo Developers

Your Personal Time Machine

The 'why' behind every decision, timestamped and searchable. Context returns when you do.

Small Teams

Shared Memory Without Meetings

Team knowledge lives in git. New devs read decision history. Context outlasts turnover.

Engineering

Architecture as Context

Architecture decisions inform future code. Agents check docs before proposing changes.

Product

Specs That Reflect Reality

Specs stay synchronized. Code changes flag specs. Intent flows from research to implementation.

Communications

Brand as Code

Brand voice is versioned, not out of sync. Agents reference messaging when writing copy.

Leadership

Strategy That Cascades

Strategy informs every line of code. OKRs connect to features. One query, not archaeology.

Context that lives with your code,
not buried in Notion.
