PromethAI is an open-source Python-based framework developed by the Topoteretes organization that provides AI agents designed to help users navigate complex decisions, establish personalized goals, and execute on them. The project began with a focus on food and meal planning as a proof-of-concept domain, but its architecture is explicitly designed to be extensible to any decision or task domain. The backend framework is built around FastAPI with LangChain chains that serve LLM-generated outputs. It uses OpenAI models for reasoning, Pinecone for storing user preferences and summaries, and supports integrations with external services like Zapier to automate downstream actions (such as blocking calendar time or sending messages). The system is asynchronous and designed for low latency. PromethAI is a product of Topoteretes, the same organization that built Cognee, an open-source AI memory platform using knowledge graphs. PromethAI itself includes a memory management module (PromethAI-Memory, now redirected to Cognee) that gives agents persistent context across sessions. The mobile application repository was last updated in April 2026. The project is openly positioned as a work in progress and is delivered without guarantees. Topoteretes' current primary development focus appears to have shifted toward Cognee (the AI memory/knowledge graph engine), while PromethAI repositories remain active but receive less frequent updates. The project is free to use under its open-source license; there is no listed commercial pricing. Key features: - Open-source Python/FastAPI backend with LangChain-based AI agent chains - Personalized goal decomposition: breaks user objectives into actionable steps - Pinecone vector storage for user preference memory and personalization over time - Zapier integration for automating downstream task execution (calendar, messaging, etc.) - Mobile app (PromethAI-Mobile) for on-device interaction with the agent framework - Asynchronous operations for low-latency agent responses - Extensible domain architecture (initial focus: food/meal planning; designed for any domain) - Memory management module (PromethAI-Memory) for persistent cross-session context, now evolved into Cognee
