Opterra vs Archive Toolkit

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 Opterra Assistant gives trade workers fast, reliable answers to building code questions—without searching through books or PDFs. Chat with an AI assistant trained on trade-specific regulations, filtered by state and local county. Every answer is grounded in cited code sections and tables, so you can verify details with confidence. Save referenced code sections for offline access, and listen to responses using high-quality text-to-speech when your hands are busy in the field.Built for real work.
