1. Is this request related to a challenge you're experiencing? Tell me about your story.

creating a long term memory in dify is really hard, but we don't need to. we should be able to integrate with mem0 or zep to do this for us. n8n and flowise already do this.

2. Additional context or comments

I asked about this on mem0 discord, and they are willing to help.

3. Can you help us with this feature?

• [ ] I am interested in contributing to this feature.
