Augment Apps and
Services with AI

LLMs have the potential to completely personalize your apps and make them smarter, but integration has its challenges. With PROMPTMETHEUS, your app simply connects to AIPI endpoints and the prompt engineering, prompt testing, prompt optimization, and model selection can be done conveniently inside the IDE.

AI Integrations

PROMPTMETHEUS provides the complete toolchain to build and deploy AI integrations. Simply compose and test a reliable prompt for the task at hand, select a suitable LLM, and publish a dedicated AIPI endpoint. Voilà, third-party services like Notion, Zapier, Airtable, etc. can now interact with your prompt.

Automate Workflows
with AI

With the rapidly evolving capabilities of large language models, tasks of ever higher complexity can be partially – or even completely – automated. If your processes and workflows involve any repetitive text-based tasks, chances are PROMPTMETHEUS can help you automate them to save time and money.
