  "account": "In 2026, various hosted memory MCP servers are available for integration with popular AI bots such as Claude, ChatGPT, and Grok Bot. The options include Mem0, Supermemory, Zep/Graphiti, Letta, Basic Memory, and Crosswalk.\n\nFor apps requiring memory recall for users, Mem0, Zep or Supermemory are recommended. If the app relies on a team's own knowledge base in Markdown format, Basic Memory is the ideal choice. When multiple agents within a single organization need stateful memory, Letta is the suitable solution.\n\nTo share information with agents from different companies, such as Claude, ChatGPT, and Grok Bot, Crosswalk is the appropriate option. It allows cross-company agents to read and write data in the same location, fostering collaboration and information sharing.\n\nWhen considering deployment, local-only servers provide a seamless experience when running on a single machine and are invisible to cloud agents. However, if the AI bots involved include ChatGPT or Grok Bot, it is advisable to opt for a hosted memory server. This ensures smooth integration and compatibility with these popular AI platforms.",
