What is memobase?

Memobase is an open-source, user-profile-based long-term memory system designed for generative AI applications. Memobase provides user memory capabilities for applications such as virtual assistants and educational tools, helping AI remember, understand, and grow alongside users. Memobase offers structured user information storage, supports time-aware memory, flexible configuration, and fast batch processing, and integrates into existing systems via APIs and various SDKs. Memobase provides personalized experiences for AI, supports large-scale user management, and is widely used in user analytics, personalized recommendations, and product optimization.

Main functions of memobase

  • User memory managementCreate an independent long-term memory profile for each user, recording the user's basic information, interests, habits, etc.
  • Time-perceived memoryThe system can record event timestamps to ensure that AI is not interfered with by outdated information, and also supports the storage and retrieval of event sequences (episodic memory).
  • Flexible configurationDevelopers can selectively store and use different types of memory based on their needs.
  • Easy to integrateIt provides APIs and SDKs in multiple languages (such as Python, Node.js, and Go) to enable rapid integration with existing generative AI systems.
  • Batch processing and high performanceIt can quickly process large amounts of data and support high concurrency and large-scale user scenarios.

The technical principles of memobase

  • User Profile BuildingBased on the analysis of user interaction data with AI (such as chat logs and behavior logs), key information is extracted and user profiles are built. These profiles are stored in a structured manner for easy retrieval and use by AI.
  • Buffer and memory refresh mechanismThe system uses a buffer to temporarily store recent user data. When the amount of data in the buffer reaches a certain threshold (such as 1024 tokens) or the idle time is too long (such as 1 hour), the data is automatically refreshed to long-term memory. Developers can also manually trigger the refresh operation.
  • Non-embedded memory systemIt enables efficient processing and storage of memory data based on non-embedded systems, achieving fast read/write speeds and low-latency responses.
  • Event Sequences and Time AwarenessThe system adds a timestamp to each memory data point, supports the storage and retrieval of event sequences, and ensures that AI can understand changes in user behavior and preferences in chronological order.
  • Flexible configuration and scalabilityDevelopers can customize the type, storage method, and update frequency of memory based on configuration files or API interfaces to adapt to different application scenarios and needs.
