What is Klorra AI?
Klorra AI offers an all-encompassing solution for custom-home bidding that goes beyond simple takeoffs. By simply uploading a PDF of the architectural plan, users can engage in a sophisticated 7-phase AI process that produces five comprehensive documents in about four hours, all of which can be accessed through the app and downloaded in either Excel or Word format. These documents comprise a quantity takeoff, a cost estimate organized by over 160 cost codes, a scope of work structured by construction trade sequence, a conflict report that pinpoints discrepancies between disciplines and items needing clarification from architects or engineers, along with verification notes that emphasize concerns raised during a quality check by a second agent for the builder’s review.
Klorra operates as a service, eliminating the need for manual inputs, such as clicking through each wall, which simplifies the process for users. Originating from an active custom home-building firm in Naples, FL, the system employs the same efficient workflow for current bids. While AI may sometimes misinterpret intricate details like custom roof designs, miss structural pages, or neglect hand-marked revisions, Klorra actively highlights these potential issues, allowing builders to verify them before any commercial use. Additionally, the first bid is provided at no charge and does not require a credit card for access. This innovative approach not only expedites the bidding process but also significantly boosts accuracy and minimizes the chances of expensive errors, making it a valuable tool for builders. Ultimately, Klorra AI stands out as a revolutionary platform that redefines how custom home bids are created and managed.
