ChainMemory gives your AI agents persistent memory that belongs to YOU — not to a single vendor.

Save a memory in ChatGPT, recall it in Claude or Gemini. Available via Chrome extension, MCP server (npm), or REST API. Every memory gets a cryptographic fingerprint and project states are anchored with Merkle proofs, so anyone can independently verify integrity — no trust required.

Memories consolidate into a structured Project Brain (decisions, milestones, risks) instead of a pile of raw notes. Multi-agent native: Claude, Cursor and GPT share one consolidated state. Free tier available.

TiDB features and specs

  • Scalability
    TiDB offers horizontal scalability, allowing you to add more nodes to handle increased loads seamlessly. This makes it suitable for applications expected to grow rapidly.
  • MySQL Compatibility
    TiDB is highly compatible with MySQL, enabling easy migration from MySQL databases and allowing developers to use familiar MySQL tools and syntax.
  • Distributed Architecture
    TiDB's distributed architecture allows it to maintain high availability and reliability, with the ability to continue operating even if some nodes fail.
  • HTAP Capabilities
    TiDB supports Hybrid Transactional/Analytical Processing (HTAP), which lets users perform real-time analytical queries on fresh transactional data without needing separate systems.
  • Strong Consistency
    TiDB ensures strong consistency across distributed transactions, maintaining data integrity without sacrificing performance.

Possible disadvantages of TiDB

  • Complex Deployment
    TiDB's distributed nature can make deployment and management more complex compared to traditional single-node databases, requiring specialized knowledge.
  • Resource Intensive
    Running a TiDB cluster can be resource-intensive, requiring more hardware resources compared to monolithic databases for optimal performance.
  • Evolving Ecosystem
    As a relatively new system, TiDB's surrounding ecosystem is still evolving, potentially leading to a lack of comprehensive ecosystem tools and third-party integrations.
  • Operational Overheads
    Maintaining and monitoring a TiDB cluster can introduce additional operational overheads due to its numerous components and dependencies.
  • Learning Curve
    For teams accustomed to traditional databases, there may be a steep learning curve when adopting TiDB, especially in understanding its distributed features and best practices.
