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
Other tools store context in the cloud. We store it in Git. That's not a feature difference—it's architectural. Architecture diagrams, API specs, decision records—all version-controlled with your code. When implementation changes, documentation is flagged for review. Context that stays current.
"Context versioned with code, not buried in Confluence."
How Teams Use Principal AI

Quality Radar
Know when things are off
Living Documentation
Keep intent and code aligned
Optimized for Agents
Built for agent-written software
Multi-Project Workspaces
Agents reason across all repos
Live Team Collaboration

As software becomes autonomous, understanding becomes the bottleneck. Principal removes it.
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.
A picture is worth a thousand lines of code.
