Helix Foundry alternatives
Other memory & RAG tools in our directory. See all memory & RAG tools →
Zep
Context layer that unifies business data, documents and conversations into memory so agents complete tasks correctly.
Claude-Mem
Gives coding agents memory across sessions by capturing what they do, compressing it and feeding the relevant context back in later.
RAGFlow
Open-source RAG engine with deep document parsing and agent features for building grounded question-answering over your files.
LeanCTX
Open-source context gateway that sits between AI tools and your code and data to control and shrink what the model sees.
Tulimoa Memory
Tulimoa Memory is a hosted, shared memory store for AI agents and agent swarms. Agents write what they learn into it during the day; overnight a separate model sorts those notes into a knowledge graph with associative recall, and each agent starts the morning with a short briefing so it reads less and knows more. It is billed per call, with starting credit to try it.
PageIndex
Document index for reasoning-based, vectorless RAG that lets agents navigate long documents like a table of contents.
