Serious software.
Clear purpose.
We build systems that help agents do useful work, help developers understand their tools, and help businesses solve difficult software problems.
Discuss your project Explore engineering servicesSee what the work makes possible.
Start with the problem. Explore the system. Inspect the engineering.
Give agents tools. Keep control of the work.
Connect AI agents to tools, files and shared memory, with permissions, human approvals and saved progress.
Private pilotSee use cases and architectureControl which actions an agent may start.
An authorization gate that checks permission at the point an integrated executor dispatches an action.
Open-source engineeringSee use cases and architectureKeep evidence separate from interpretation.
Built as Witness. Preserve how a claim came to exist, with distinct records for observations, inferences and generated material.
Public-source prototypeSee use cases and architectureBring coding tools and ongoing work together.
A Rust work assistant with model routing, repository tools, saved sessions and bounded workers.
Open source · personal-use milestoneSee use cases and architectureFind claims that need a closer look.
Research tooling for assembling source-backed evidence packets and routing bounded questions for human review.
Open-source research buildSee use cases and architectureUnderstand why your build went red.
Build intelligence that groups failures, finds recurring errors and connects them with earlier build history.
Developer toolSee use cases and architectureHave a different problem?
That’s where we start.
Custom software. API integrations. Application rescue. Web and mobile products. We work from the problem through implementation, testing and handoff.
