About Promptmetheus
Promptmetheus provides a Prompt Engineering IDE that helps users compose, test, and optimize prompts for AI automations, agents, and workflows. It supports many models and offers features like prompt versioning, automatic evaluations, and a configurable model catalog. The platform is used by thousands of users to build and refine prompt-based systems.
Users can assemble prompts from text and data blocks, run automatic evaluations, and organize work within projects and dashboards. The tool exposes model parameters and cost estimation, and enables real-time synchronization across devices and team members.
The service offers a catalog of models from multiple providers and allows testing prompts with 150+ LLMs while experimenting with different model parameters for better results. It also provides data export options and traceability of changes across the design workflow.
Promptmetheus outlines plans, platform availability, integrations, and limits across its documentation and pricing pages, including the ability to connect providers, manage teams, and deploy prompts within scalable work environments.
