mem9 is a long-term memory plugin for Dify agents and workflows.

It lets applications store important user facts, preferences, decisions, and contextual information into mem9, then retrieve relevant memories when needed to improve personalization and continuity across conversations. The plugin provides two tools:

• memory_store, which uses mem9 smart ingest to extract and reconcile memories from text.
• memory_search, which returns concise ranked memory results for downstream LLM use.

It uses a mem9 API key for authentication.
