Gateman is a seatbelt for AI usage.

Gateman sits quietly in the browser and gives your team a gentle nudge before sensitive info gets shared.

It doesn't spyIt doesn't slow people downIt steps in only when it matters

How it works

Step 1

Set your guidelines

Choose what your team should double-check before sharing:

  • Secrets & credentials

  • Customer personal data

No YAML. No policy docs.

Step 2

Gentle guardrails

When something looks sensitive:

  • Gateman gives a friendly heads-up

  • Or pauses for review (high-risk items)

Checks run locally, on-device.

Step 3

Get signal, not noise

See high-level insights without invading privacy:

  • Alerts raised

  • What was stopped vs warned

Your prompts are never stored.

Your team already uses AI. Keep it company-safe.

Gateman adds gentle guardrails right where your team works: in the browser.

On-device checks. No raw prompts stored.
