Every organization runs on processes: approvals, onboarding, reviews, escalations. Most live as a static picture that describes what should happen. It cannot show what actually does.
To read a static diagram, someone has to trace the arrows with a finger and hold every prior decision in their head.
That gap between the drawing and the reality is where dead ends ship and steps get skipped, and nobody notices until a real person gets stuck.
nimu makes the diagram itself run. Build a flow, press play, and walk it. You always see why each path is open.
nimu is built for the people who own processes, not engineers. That decision shapes the product. There is no expression language anywhere. Logic is a checklist you could read aloud. An agent can draft or edit the same model you do, always with your approval.
Four principles behind the product.
The moment a product asks a process owner to write amount > 50000 && !flagged, it has chosen a different user. Gates in nimu are checklists over named facts, built with pickers and readable by anyone.
A canvas is a thinking space and half-built flows are normal. Validation flags dead ends, impossible gates, and unreachable steps in plain English. It never stops you building or pressing play.
Every mutation, human or agent, goes through one explicit, undoable path. The agent proposes and you approve. Nothing is rewritten silently; the architecture prevents it.
The same pure engine powers playing a flow, validating it, replaying a saved run, and the walkthrough a recipient traverses from a link. So what you test is exactly what they see.
We did not invent the execution model.
Every serious tool in this space (statechart editors, narrative engines, interactive fiction) converged on the same primitives: variables, conditions that gate choices, and a step-through simulator. That convergence is evidence the model works.
What nobody built is the authoring experience for the people who own processes: no syntax anywhere, an agent that edits with your approval, runs saved as replayable artifacts, and walkthroughs anyone can open from a link. That is what nimu does.
