ReBillion.ai

ReBillion.ai is a vertical AI platform aimed squarely at residential real estate transaction coordinators (TCs), agents, and brokerages. It ingests purchase agreements and ancillary docs, then pulls out parties, contingencies, key dates, and state-specific compliance requirements, auto-building a timeline and checklist that syncs to your calendar. It also reads inspection reports, loan files, and insurance notices, and drafts Gmail replies so the TC workflow stops being copy-paste-and-pray.

The product is best understood as a TC-in-a-box: the $199/mo AI Toolkit gives you the document-intelligence and compliance layer, while $499/mo bolts on a US-trained human assistant for the parts a model still shouldn't own. State-specific compliance across ~10 US states is the real moat here — generic LLM wrappers don't know the deadline math, and ReBillion claims to. It integrates with the TC tools brokerages actually use: OpenToClose, Brokermint, SkySlope, FollowUpBoss, Dotloop, and Google Drive.

This is a narrow B2B tool, not a horizontal AI assistant. If your shop already runs on one of the supported TC platforms and you're drowning in deadline tracking, the ROI math is straightforward. If you're outside US residential real estate, it's irrelevant.
