Your codes, connected to your drawings
We read the state and local codes and amendments that governments publish online, the way a human reviewer does. Our AI opens it in a web browser, goes to the section or table, and cites it in the finding with a link to the source. The model codes most states adopt, such as the International Building Code, are licensed; we use their text only where a license allows it, and you can upload a copy you’re licensed to use. We reference the section. We never copy or distribute code text.
We detect the codes your drawings cite in the code analysis, cover sheet, and general notes. Add or remove codes, and note the edition, local amendments, and project requirements.
Mark the drawings you want reviewed as Check this file. If you upload a code, such as a standard you’re licensed to use or an unpublished amendment, set it to Code and Use as reference.
Follow the linked drawing and code section, check applicability, and have the responsible professional verify the issue.
