Opterra

Building code books contain thousands of sections, change across jurisdictions, and are rarely easy to navigate when you just need an answer. Opterra turns them into something you can actually ask.

Ask the assistant a question in plain language and it works through the codes that apply to your jurisdiction to find the answer. Every response points back to the source, so you can tap the citation and read the actual section yourself — including its tables and figures.

And for the quick stuff that comes up on the job, Opterra keeps a few essentials close at hand.

• Tap-to-open citations that take you directly to the referenced section
• Feet, inches & fractions calculator for everyday field math
• Equipment and product lookups with the original sources
• Chat history, clean copy & read aloud
