Illustrative example, not a real project.

  • Every number can be reproduced by an engineer.
  • Every value comes from your drawings, or we ask you for it.
  • No set leaves without review by a licensed PE.

AI drafts and checks. All review is done under the responsible charge of a PE.

Find the issues in a set in minutes.

Our plan check runs a drawing set against the city's checklist and cites the sheet behind every finding. There's no queue: it runs when you open the set, and a reviewer makes every decision.

Praneet Erusu, PE, founder of Rene AI

Built by engineers

We build our tools from how engineering review is actually done, so every job is auditable. If something goes wrong, we can find the exact step where it entered and fix it for every job after.

The steps that carry legal responsibility stay with a licensed engineer, by design. AI drafts and checks. Our engineers decide.

Questions clients ask

How fast is turnaround?

Stamped solar sets come back in 24 hours. Plan check results come back in minutes, because the tool runs as soon as you open the set.

Who stamps the work?

Structural work is stamped by our Civil PE, licensed in CA, AZ, NV, TX, CO, FL, MA and NJ.

Does AI do the engineering?

No. AI drafts and checks. Calculations run in tested modules, and a licensed PE reviews every set in responsible charge.

What if the city issues corrections?

They're included. We answer the city's comments on the work we delivered.

How does pricing compare?

Lower than a traditional engineering firm, because our tools do the repetitive work. We quote each job up front.

What if my project has an unusual configuration?

We write and test a new calc module before it's used on your job. After that, it runs on every similar project.

Does plan check approve plans?

No. It flags issues and cites the sheet behind each one. A reviewer decides on every item, and the city makes the approval.

Do you plan-check projects you designed?

Never. We don't plan-check a set our firm prepared.

When do the plan set app and Title 24 open?

Both are coming soon. Join the waitlist and we'll tell you as soon as they open.

How do I get started?

Email us your project for a quote, or ask for plan check early access. We'll reply with next steps.

Start with one project.

Send one set and see the difference: the checks, the calc package and the turnaround.

Need drawings or calcs?

Send us your project and we'll quote it. Solar sets are stamped in 24 hours, and city corrections are included.
