Private beta · 2026

AI that builds.
And proves it.

SignetOne is a personal agent you own. Describe the software you need and it builds, tests, and delivers it, verified end to end. Not vibe-checked. Connect your email, calendar, and chat and it works for you all day. Every risky action waits for your word.

$ describe your app

"A CRM with sign-in, contacts, and a sales pipeline"

plan approved: 28 acceptance checks

How it works

01

Describe

Say what you want in plain language: an app, an agent, an automation. It asks questions until the picture is complete.

02

Approve the plan

Before anything is built, you approve a plan written in plain words. That plan becomes the contract every delivery is checked against.

03

It builds. And proves it.

Every delivery is machine-verified against the plan you approved: clicked through, probed, even restarted. All before you ever see it.

04

Own

It runs in your own space, with your data and your accounts. Your code, your deployment. Leave anytime.

Power it
can prove.

Verified, not hoped

Most AI builders hand you code and hope. A SignetOne delivery passes machine-run acceptance checks derived from the plan you approved: real sign-ins, real clicks, real restarts. Anything less does not ship. An honest "not done yet" always beats a false "done".

Your word gates every risk

Connect your email, calendar, and chat. Reading is free. Acting is gated. Sending, paying, posting, anything irreversible waits for your explicit yes, every single time. Even running unattended, it escalates instead of guessing.

You own everything

Your code, your database, your deployment. No proprietary runtime. No lock-in. Export and leave anytime.
