Understands your dev stack
Why Noesa
A deterministic signal cascade attributes your activity to the right project — most of it without ever calling a model.
Your screen never leaves the device — Noesa reads only the foreground app and window title and OCRs frames on-device. Only redacted text (titles + intent) reaches the AI, and only through our key-custody proxy — no API key ships in the app.
The active repository maps straight to a project — the strongest signal a developer can give. Deterministic. No LLM, no guessing.
repo:noesa → Noesa
Content-change sampling, not a blind timer. Step away and idle time is never billed.
One project, tracked across both machines. Native capture on each, shared billing.
Hours per client × rate, reconciled to the cent. Copy clean CSV straight into your invoice.
How it works
Noesa notes the foreground app, window title, and active git repo — entirely on-device — only when the activity actually changes.
A cascade resolves the project: repo and hint matches first, a cheap text model only for the ambiguous leftovers.
Confirm or adjust blocks in the timeline, then export billable hours per client as CSV. Nothing is billable until you say so.
Privacy
Raw activity stays in a local store. The only thing that ever syncs is the sanitized work block — a project id, a time range, and the evidence that earned it.
// the entire payload that syncs { "projectId": "noesa", "start": "09:12", "end": "11:36", "billable": true, "evidence": ["repo:noesa"] } // no screenshots · no titles · no keystrokes
Install Noesa, define a client and project, and let the hours attribute themselves.
