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.

PhysicsJS features and specs

Simplicity
PhysicsJS is designed to be simple to use, making it accessible for those who are new to physics simulations or JavaScript game development.
Modularity
The library is highly modular, allowing developers to use only the components they need, which can lead to more efficient and manageable code.
2D Physics Engine
PhysicsJS provides a robust 2D physics engine for simulating real-world physics in web-based applications, which is beneficial for game development.
Open Source
Being open-source, PhysicsJS allows developers to access and modify the source code to suit their needs, fostering a collaborative community.

Possible disadvantages of PhysicsJS

Limited Features
Compared to some other physics engines, PhysicsJS may offer fewer features and capabilities, which could be a limitation for complex projects.
Community Support
PhysicsJS might have less community support and resources available than more popular libraries, making it harder to find solutions or guidance.
Performance
For highly demanding applications, PhysicsJS might not perform as well as other more optimized physics engines, potentially leading to slower performance.
Maintenance
If the library is not actively maintained, it might lack updates and bug fixes, which could be a challenge for developers looking for long-term stability.
