Your agents keep working. The risky steps wait for you.

Detent lets everyday agent work straight through and stops only before steps that can't be undone: a force push, a deploy, a payment. Approve on the desk device or your phone. Every decision is signed and kept.

A risky step arrivesThe agent stops and waits. Everything else keeps running.

1 of 5

Agents run for hours now, several at once.

A single afternoon can mean hundreds of commands across a handful of projects. Approve each one and the agent crawls. Approve none and nobody checks the steps that matter.

2 of 5

Every action gets a risk level before anything runs.

Reading files and running tests are let through. A force push to main, a production deploy or a refund is marked high risk. Companies set their own rules; the default ones work on day one.

3 of 5

Only the high-risk steps stop.

The agent keeps working on everything else. One question waits, with the full command and a plain reason why it matters.

4 of 5

A person decides, on the desk or on their phone.

Wind the Detent knob a full turn and press, or approve with Face ID or Touch ID. A quick reflex tap never counts, and holding the button stops every agent at once.

5 of 5

Every decision is signed and chained.

Who approved, what, when, and how. Each record links to the one before, so a changed or deleted line shows up. Export it, or hand the auditor a ready report.

One control, wherever the work is.

A machined desk device for people who want a physical yes. Software that works without it for everyone else.

Effort that matches the risk.

A high-risk step needs a full 360° wind of the big knob, then a press within five seconds. Try it: drag the knob, scroll over it, or use the arrow keys. Hold the button to deny.

Wind the big knob a full turn

Detent in graphite: a low aluminium slab with a screen, a large knurled knob, a small knob and an orange button.

Machined from one block.

124 × 76 mm aluminium, 2.41-inch AMOLED, a 30 mm knurled steel knob. It shows the exact command, not a coloured light.

Hold two seconds. Everything stops.

Every running agent stops at its next step. It's recorded, and starting again is one message away.

No device? Use your phone.

Approve with Face ID, Touch ID or Windows Hello. Each approval is a fresh passkey signature tied to that one action.

Works with the agents you already run.

One install command connects each agent's own approval hook. Anything else, from a script to a git hook, can call detent ask.

A record nobody can quietly edit.

Name, time and meaning on every decision, each chained to the one before with SHA-256. Export as CSV or JSON.

Built for one desk, or ten thousand.

Fails safe

Unplugged or no answer in 110 seconds, and your agent asks on screen the way it always did.

Questions

Won't this slow my agents down?

No. By default Detent only asks before steps that can't be undone, like a force push, a deploy or a merge into main. Everything else goes straight through, and finished work can wait for review while the agent moves on.

Can an agent approve its own request?

No. A risky step only goes ahead after a turn and press on the device, or a passkey check with your face, fingerprint or PIN on your phone. Nothing an agent prints or sends can do either.

Does anything leave my computer?

Not for individuals: there is no account and no cloud service. Companies connect computers to their own Detent server, which they can run inside their own network.

What happens if Detent is unplugged?

Nothing changes for your agent. If nobody answers within 110 seconds, it shows its normal approval prompt on screen.

Does Detent help with audits and AI rules?

It keeps the record auditors ask for: the person's name, the date and time, and what the decision meant, each line chained to the one before. Holding the button to stop every agent is the kind of stop control the EU AI Act describes. Detent is one control, not a certificate; what applies to you depends on your company.

When does it ship?

The working prototype is being built now. The Kickstarter follows once developers have used it daily. Follow the Kickstarter page to hear the date first.
