Do I cancel my apps?

Yes. Cancel the app stack.

I built Merlin for Construction so you can get rid of app fatigue. Nothing new to install: only Claude, the Merlin for Construction plugin, and the tools you already use, connected.

What stays: Claude, the plugin, and your email, calendar, QuickBooks and files.

Beyond the job

Austin answers every call.

Day or night, he picks up, answers questions and books the estimate visit on your calendar.

Austin is an AI assistant. The voice and name are examples.

The same plugin also gets you found when customers ask AI, posts your finished jobs, screens applicants and trains new hires.

Questions

Before you
start.

Do I cancel Buildertrend, CompanyCam and my other apps?

Yes. I built Merlin for Construction so you can get rid of app fatigue. No new apps to install: only Claude, the Merlin for Construction plugin, and the tools you already use, connected.

What does it cost?

Set it up yourself: $0 setup and $169 a month. Or we set it up for your whole company: starting at $2,495, then $169 a month. Both are plus your Claude plan.

When can I start?

Both buttons put you on the waitlist. We let people in in small groups and email you when your spot opens.

What do I need to run it?

A Claude plan, the Merlin for Construction plugin, and the tools you already use. No new app for your crew to learn.

Will it send anything on its own?

No. Quotes, orders and messages wait for your OK.

Does it work for my size of company?

It runs for a builder with two jobs or twenty. The setup price grows with how many jobs and people move over.
