The coding agent we work in.

Yes. The app is free to download and use, with no account and no login. You pay OpenRouter for the model tokens you use, at their prices; nothing comes to us.

Frontier models do the most on their own, and root is at its best with them. Where it changes things is on smaller, cheaper models that write good code but stumble over tool calls on a long task: with Jev choosing each step and Dhee remembering the project, they finish work they would otherwise drop.

A decision model. Before every step it scores the options — answer now, or which tool to call next — and the agent takes that step. The model you chose writes the code; Jev keeps the task moving. It runs through OpenRouter on your same key.

A memory file is text an agent appends to and rereads. Dhee keeps typed memories — a decision, a convention, a command, a preference — scoped to the project or to you, brings back the ones that matter for the request, and replaces a fact when it changes instead of piling the new one beside it. It is the memory behind Tura.

After real work, a reviewer reads what root did and proposes a skill — a step-by-step playbook — and memories. You keep or discard them, or let root keep what passes its overfit check. Each skill is then measured on the turns that use it: a new version that does worse than the one it replaced is rolled back, and one that hurts is retired.

root runs on your Mac. What the model needs to read goes to the model you chose, through OpenRouter, under your key. Web searches, if you leave them on, go to a search service. Nothing goes to us.

It asks before editing files or running commands unless you choose otherwise, never reaches outside the folder you opened without asking, and every turn can be undone.

Macs with Apple silicon on macOS 13 or later.

Every day. This is the coding agent our team works in, the same app you download.
