AI-powered care coordination for primary care

Agents that Build Deterministic Web Automations

Saffron Health is building AI agents that automate specialist referrals for primary care. Primary care staff spend hours each day on tedious coordination work: searching for in-network specialists, filling out authorization forms, and chasing down medical records. Saffron's agents find available in-network providers, complete prior authorizations, and help patients book appointments, which lowers administrative costs and improves access to care.

Libretto is a token-efficient CLI and agent skill that generates production-ready browser automations as code in your repo. The problem: Most browser automation tools work by sending an AI agent to operate a website in real time, like a robot typing and clicking on your behalf. This is slow, expensive, and unpredictable. They rely on fragile DOM parsing that breaks on legacy and complex sites, and you can never fully trust what the agent will do on unintuitive or inconsistent workflows. Our approach: Libretto helps your coding agents generate workflows as actual, readable code during development, not at runtime. Under the hood it combines Playwright with direct in-session network/API calls for reliability and bot detection evasion. It also supports step-through debugging and a read-only mode to prevent accidental data changes while your agent builds and debugs workflows. This makes Libretto cheaper, faster, and easier to maintain, especially for more complex websites and high stakes workflows.
