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.

Convex.dev features and specs

Seamless Deployment
Convex.dev handles the infrastructure and deployment, allowing developers to focus on building applications rather than managing servers and scaling issues.
Real-time Data Synchronization
Convex.dev provides built-in real-time data syncing which facilitates collaboration features and dynamic applications without additional configuration.
Backend as a Service

Possible disadvantages of Convex.dev

Limited Customization
As a managed service, there may be constraints on customization compared to building a backend from scratch, which might limit certain advanced configurations or optimizations.
Vendor Lock-In
Relying on Convex.dev could lead to a degree of vendor lock-in, making it potentially difficult to switch providers or migrate to self-managed infrastructure in the future.
Pricing Complexity
Potential users might find pricing complex or restrictive depending on usage patterns, especially if there is a high volume of data syncing or transactions.
Learning Curve
Despite its abstractions, new users might encounter a learning curve to fully understand and leverage all of Convex.dev's functionalities effectively.

Bringing Convex Dashboard into my dev environment
When I first started using convex, I realized how awesome and easy it was to use the dashboard. It offers an amazing overview of logs, the ability to edit table data, and view your app health. However, as a developer who always has an insane amount of browser tabs open, I found myself constantly switching back and forth just to check on things, and with the massive amount of tabs, I always spent more time looking... - Source: dev.to / over 1 year ago
