Overview

OpenClaw is an autonomous AI-powered real estate platform for the Austin/Travis County market. It replaces the traditional human real estate agent with Odie, an AI persona that orchestrates five specialized sub-agents — Brain, Voice, Closer, Lawyer, and Banker — behind a single conversational interface.

The system handles both sides of a property transaction (buyers and sellers) with built-in broker oversight and human-in-the-loop escalation for critical decisions like contracts, offers, and counter-offers. Fair Housing compliance is enforced at every layer.

Architecture

• Turborepo monorepo with two apps (web and api) and shared packages
• Dual-LLM tier strategy: Claude Sonnet for complex reasoning, Haiku for fast utility tasks
• XState finite state machine driving the full transaction lifecycle — no ad-hoc DB writes
• Multi-channel communication: Web chat, Telegram bot, and Twilio SMS
• Human-in-the-loop gates for broker review before high-stakes actions
• Fair Housing compliance: Regex blocklist on all outbound messages

Key Features

• Multi-Agent Orchestration: Five specialized agents coordinated through a central AI persona
• State-Machine Transactions: XState-driven lifecycle ensures reliable, auditable deal flow
• Instant Property Analysis: Rapid valuations and offer strategy generation
• Compliance-First Design: All messaging fact-checked and Fair Housing certified
• Multi-Platform Access: Available via web, Telegram, and SMS simultaneously
