Open tools for work with AI
Intelligence,
put to work.
Models keep getting better.
We build the tools that help you put that intelligence to work—with evidence you can inspect, checks you define, and context you can keep.
01 / What we build
One product. A connected workflow.
Grainulator
Keep the model.
Build on the work.
An answer is a beginning. Grainulator helps you turn it into a body of work: claims with sources, challenges worth answering, and checks that tell you what still needs attention.

Your model.
Your agent.
Your judgment.
Connect through a provider, a compatible endpoint, or your existing agent workflow.

- Checks
- What has actually passed
- Context
- What the next step needs
Keep moving
A decision.
A correction.
A next step.
Take the session into your workflow, with the reasoning and unfinished work intact.
02 / How we think
Better models deserve
better ways of working.
The model will change. Your standards—and the work you’ve already done—should carry forward.
- 01
Choice at the center.
Use the intelligence that fits the task. Keep the workflow portable through explicit interfaces and files you can take with you.
- 02
Evidence over confidence.
A persuasive answer still needs support. Keep facts, assumptions, risks, and recommendations distinct. Make room for “we don’t know yet.”
- 03
Checks that mean something.
Let tests and evidence set the bar. A failed check should explain the next useful step; a model saying “done” should not settle it.
- 04
Work that outlasts a chat.
Preserve the context, sources, settings, and completed work. Pick it up again without rebuilding the whole story.
03 / Built in the open
A product you can inspect.
A direction you can shape.
Grainulator brings research, verification, memory, and handoff into one project. The capabilities belong together, so you can spend your time on the work.
We’re consolidating the earlier tools into that shared foundation. Their repositories and history remain available as the transition takes shape.
