Lab: rough prototypes I'm testing

40 early prototypes with demo data. I want to know which ones you would actually use, so every demo has an “I’d use this” button.

AI agents and security 8

Tools for teams putting AI agents to work, and for keeping devices and systems safe.

For: Teams letting AI agents change customer data, billing or production systems.

Playbooks: AI agents inside service businesses 6

Six workflows I keep hearing about from people who run trades, clinics and professional firms. In each one an AI agent does the repetitive part and a person approves what matters. Each is a clickable prototype with made-up data.

PlaybookTradesPhones

After-Hours Dispatch

An AI phone agent answers after-hours calls for HVAC, plumbing and restoration, sorts emergencies from next-day jobs, and sends the on-call tech the route, materials and ETA.

For: Trades and field-service businesses with an on-call rotation.

Try the demo PlaybookTradesFollow-up

Quote-to-Book Follow-up

After an estimate goes out, the agent answers “does that still stand?” and “when can you start?” by text and email, shows the estimate line it used, and hands hot leads to whoever closes.

For: Contractors and home-service businesses that send a lot of estimates.

Try the demo PlaybookTradesScheduling

Route-and-Confirm Morning Ops

Reads yesterday’s results, today’s schedule, weather and traffic, drafts the day’s routes with a reason for each change, confirms 30-minute arrival windows and fills cancellations from a waitlist.

For: Dispatchers running crews or technicians across a service area.

Try the demo PlaybookClinicsPhones

After-Hours Reception for Clinics

Answers after-hours calls, books into the clinic calendar, warm-transfers emergencies to the on-call clinician, and leaves the front desk a summary in the morning.

For: Dental, med spa, veterinary, chiropractic and optometry clinics.

Try the demo PlaybookClinicsInsurance

Insurance Verification Copilot

Checks tomorrow’s patients against their plans, flags coverage gaps for the front desk with the plan wording behind each one, and drafts pre-authorization requests for review.

What every playbook has in common

  1. A person approves every final action. Booking a slot, dispatching a truck or sending a message waits for sign-off, unless an auto-approve rule the owner set covers it, and that rule can be switched off at any time.
  2. Reasons, not scores. Every decision shows the words that triggered it, the rule it matched and how confident it was, so staff can read the reasoning.
  3. Nothing is dropped silently. A request the agent declines is logged with the reason, and the full history is always there.
  4. Overrides are recorded. When staff change a decision, it’s logged, and every settings change can be rolled back without an engineer.
  5. Shadow mode first. The agent runs next to the people who do the work and its decisions are compared with theirs before it’s allowed to act.
  6. An off switch from day one. Every playbook has a manual fallback, like the old answering service or a person at the front desk, that you can switch back to in one click.
