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.

PSPDFKit features and specs

  • Comprehensive PDF Toolkit
    PSPDFKit provides a wide range of PDF functionalities including viewing, annotating, signing, and form filling, which makes it a one-stop solution for PDF handling within applications.
  • Cross-Platform Support
    PSPDFKit offers support for multiple platforms including iOS, Android, Windows, Web, and macOS, allowing developers to maintain consistency in PDF operations across different environments.

Possible disadvantages of PSPDFKit

  • Cost
    PSPDFKit is a commercial product with licensing fees, which can be expensive for some organizations, especially smaller ones or those with limited budgets.
  • Complexity for Simple Applications
    For projects that require only basic PDF functionalities, the extensive features of PSPDFKit might be overkill, adding unnecessary complexity.
  • Dependence on Vendor
    Using a third-party library like PSPDFKit introduces a dependency on the vendor, which can be a risk if the vendor changes pricing models or discontinues support.
  • Learning Curve
    While there is comprehensive documentation, the breadth of features means that there can be a learning curve for developers new to PSPDFKit, which could delay implementation.
