MemU is an agentic memory framework for LLM and AI agent backends. It receives multimodal inputs (conversations, documents, images), extracts them into structured memory, and organizes them into a hierarchical file system that supports both embedding-based (RAG) and non-embedding (LLM) retrieval.
MemU is collaborating with four open-source projects to launch the 2026 New Year Challenge. 🎉Between January 8–18, contributors can submit PRs to memU and earn cash rewards, community recognition, and platform credits. 🎁Join the community here: https://discord.gg/KaWy6SBAsx
| Feature | Description |
|---|---|
| 🗂️ Hierarchical File System | Three-layer architecture: Resource → Item → Category with full traceability |
| 🔍 Dual Retrieval Methods | RAG (embedding-based) for speed, LLM (non-embedding) for deep semantic understanding |
| 🎨 Multimodal Support | Process conversations, documents, images, audio, and video |
| 🔄 Self-Evolving Memory | Memory structure adapts and improves based on usage patterns |
MemU organizes memory using a three-layer architecture inspired by hierarchical storage systems:
| Layer | Description | Examples |
|---|---|---|
| Resource | Raw multimodal data warehouse | JSON conversations, text documents, images, videos |
| Item | Discrete extracted memory units | Individual preferences, skills, opinions, habits |
| Category | Aggregated textual memory with summaries | preferences.md, work_life.md, relationships.md |
Key Benefits:
- Full Traceability: Track from raw data → items → categories and back
- Progressive Summarization: Each layer provides increasingly abstracted views
- Flexible Organization: Categories evolve based on content patterns
MemU processes diverse content types into unified memory:
| Modality | Input | Processing |
|---|---|---|
conversation |
JSON chat logs | Extract preferences, opinions, habits, relationships |
document |
Text files (.txt, .md) | Extract knowledge, skills, facts |
image |
PNG, JPG, etc. | Vision model extracts visual concepts and descriptions |
video |
Video files | Frame extraction + vision analysis |
audio |
Audio files | Transcription + text processing |
All modalities are unified into the same three-layer hierarchy, enabling cross-modal retrieval.
