In their own words
AI Rule Engine
AI Rule Engine automates operational decisions governed by customer-authored policies, including claims triage, eligibility, prior authorization, and underwriting referral. Customer rules determine outcomes; AI can classify, extract, or summarize unstructured material into facts used by those rules. Run traces show which rules fired, their order, matched values, and changes to decision context. Static verification can flag rules that cannot fire, duplicates, conflicting writes, and input combinations without a matching rule; saved tests can gate releases. The product supports outbound HTTP actions, marketplace extensions, durable storage actions, and external API access. Native model options include Anthropic Claude, OpenAI ChatGPT, Azure OpenAI, Google Gemini, and xAI Grok, using customer-provided keys. All plans include an MCP server for configured assistants to trigger workflows and access permitted files and logs. Free, Pro, Team, and Enterprise support shared hosting; Enterprise can use up to three dedicated Azure hosts. Free is free, Pro $49 a month, Team $199 a month, and Enterprise $999 a month. The maker notes it has no SOC 2 attestation, DPA or BAA, or independent third-party penetration test.
