ChainMemory gives your AI agents persistent memory that belongs to YOU โ€” 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 โ€” 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.

Pmwiki features and specs

  • Ease of Use
    PmWiki is designed to be straightforward and user-friendly, requiring minimal technical expertise in HTML or CSS, which makes it accessible for non-technical users to create and edit pages.
  • No Database Required
    PmWiki stores its content in flat files, so it doesn't require a database engine like MySQL. This can simplify installation and maintenance for users not familiar with database management.
  • Customizability
    PmWiki offers a flexible template and skins system that enables users to easily modify the appearance and functionality of the site without requiring in-depth programming knowledge.
  • Access Control
    The platform provides robust access control features, allowing administrators to define who can view or edit content on the wiki, which is beneficial for managing collaborative work.
  • Large Community and Support
    PmWiki has an active community and extensive documentation, offering a wealth of resources and community support that can assist users with troubleshooting and expanding their wiki.

Possible disadvantages of Pmwiki

  • Limited Built-in Features
    Compared to other more comprehensive content management systems, PmWiki may lack some advanced built-in features, requiring additional customization or use of plugins to extend functionality.
  • Scalability Concerns
    As PmWiki uses a flat file structure, performance may degrade with very large wikis or high traffic volumes unless optimizations are put in place.
  • Plugin Dependency
    To gain additional functionalities beyond the core features of PmWiki, users often need to rely on third-party plugins, which might vary in quality and support.
  • Less Modern Aesthetic
    Some users might find the default themes and visual aesthetics of PmWiki to be less modern compared to newer platforms, which might require more effort to update or customize.
  • Static Output
    Without a database backend, integrating dynamic content can be challenging, limiting the ability to create dynamic, database-backed applications directly within PmWiki.

  • MCP Server
