Development Platform

Compose, test, and evaluate one-shot prompts for the leading AI platforms and seamlessly integrate them into your apps and workflows

Integrates with

PROMPTMETHEUS is an Integrated Development Environment (IDE) that helps you augment your products and workflows with the superhuman capabilities of ChatGPT and other Large Language Models (LLMs).

Easily craft high-performing prompts and (optionally) deploy them to bespoke AIPI endpoints that your apps and integrations can interact with.

No coding skills or technical knowledge required!

What is a one-shot prompt?

Unlike chatbots or agents, one-shot prompts deliver predictable outputs based on a single request. One-shot prompts are ideal for integration into apps and automated workflows.

What is an AIPI?

An AIPI (Artificial Intelligence Programming Interface) is similar to a conventional API, but instead of an application its endpoints mediate interactions with an AI model (LLM, etc).

What does "bring your own key" mean?

Bring Your Own Key (BYOK) means that you have to provide your own API keys for OpenAI, Anthropic, etc. BYOK has the advantage that you do not have to share any rate limits, but therefore you do have to set up your own accounts and payment methods and make sure that your API keys do not leak to the network.

What can I build with PROMPTMETHEUS?

There are no limits on what you can build, but the design use case is to build tools and AIPIs to automate repetitive tasks, for instance spam detection, sentiment extraction, content generation, etc.

Do I need to be a developer to use PROMPTMETHEUS?

Not at all. PROMPTMETHEUS is designed for developers and non-technical users alike. There are no coding skills required.

Are there any integrations?

PROMPTMETHEUS will develop integrations for Zapier, IFTTT, etc. and provide SDKs for Python, JavaScript, and other popular programming languages.
