What they do

Problem

Building and deploying reliable AI agents across different model providers and runtimes is complex and often requires brittle, code-heavy configurations.

Solution

OpenProse is a natural-language agent framework that lets you define agent intents, responsibilities, and outcomes in structured English/Markdown so agents can self-configure and run portably across providers and harnesses.

Who it's for

Developers and teams building AI agents and automations who need portability and easier agent specification.
