## Choose when

### Choose mempalace if…

- License: mempalace is MIT, cognee is Apache-2.0.
- Both MemPalace and cognee offer AI memory platforms designed for agents, potentially serving similar purposes but with unique approaches or architectures.
- Tags unique to mempalace: memory, llm, ai, python.
- Also covers Data & Retrieval.
- - You require local storage for conversation history and want to avoid cloud dependencies.

### Choose cognee if…

- License: cognee is Apache-2.0, mempalace is MIT.
- Requirements: Requires environment configuration to ingest data in any format and build a self-hosted knowledge graph..
- Both MemPalace and cognee offer AI memory platforms designed for agents, potentially serving similar purposes but with unique approaches or architectures.
- Tags unique to cognee: vector-database, knowledge-graph, ai-agents, agent-memory.
- Also covers AI Agents.
- You need to integrate robust, persistent long-term memory capabilities into your AI agents across multiple sessions.

## When NOT to use mempalace

- - When requiring real-time collaboration across multiple devices, as MemPalace is focused on local storage.
- - If your project strictly requires cloud-based solutions for ease of deployment and scalability.

## When NOT to use cognee

- If you seek immediate deployment without the need for setting up or managing a self-hosted service, as Cognee requires a managed environment to operate.
- You are looking for a fully managed service with minimal operational overhead, since Cognee is an open-source platform requiring setup and maintenance.
