## Choose when

### Choose mempalace if…

- Both MemPalace and memsearch offer persistent memory layers for AI agents but utilize different storage backends (ChromaDB vs Markdown + Milvus).
- Tags unique to mempalace: ai, chromadb, llm, memory.
- Also covers Model Training.
- mempalace ships Docker support for self-hosted deployment.
- When you need a highly benchmarked solution for managing AI model memories, MemPalace can provide superior performance due to its optimization features integrated specifically around ML model needs.

### Choose memsearch if…

- Both MemPalace and memsearch offer persistent memory layers for AI agents but utilize different storage backends (ChromaDB vs Markdown + Milvus).
- Tags unique to memsearch: agent-memory, long-term-memory, milvus, semantic-search.
- Also covers AI Agents, Data & Retrieval.
- When you need robust integration with AI agents like Claude Code or Codex

## When NOT to use mempalace

- Avoid if requiring a proprietary system where full transparency or customization of the memory management layer may not be necessary, since MemPalace is open source and might involve deeper technical
- If your project strictly adheres to non-MIT licenses, then MemPalace might not be suitable due to its MIT license which may conflict with licensing requirements.

## When NOT to use memsearch

- If your application doesn't require integration with specific AI agents like Claude Code
- In cases where only simple text data storage without semantic search is needed
