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.

GNU M4 features and specs

  • Portability
    GNU M4 is highly portable and can run on almost any Unix-like operating system, which makes it versatile for various environments.
  • Macro Capabilities
    It offers powerful macro processing features that are useful for a wide range of text processing tasks, such as configuring scripts, code generation, and templating.
  • Simplicity
    M4 is relatively simple to use for basic macro processing tasks, which makes it accessible to new users and suitable for straightforward applications.
  • Integration
    GNU M4 often integrates well with other tools and scripts, making it a useful component in build systems and automated workflows.

Possible disadvantages of GNU M4

  • Limited Built-in Functions
    Compared to more modern scripting languages, M4 lacks a wide range of built-in functions and features, which may limit its use for more complex tasks.
  • Steep Learning Curve
    While simple tasks are easy to set up, mastering M4 for more advanced uses can require a deeper understanding of its syntax and capabilities.
  • Debugging Difficulty
    Debugging macros in M4 can be challenging, especially for large scripts, due to the lack of advanced debugging tools and support.
  • Performance Considerations
    For very large and complex scripts, performance may become an issue, as M4 is not optimized for handling large-scale data manipulation compared to more modern alternatives.
