Memory Sync is a Chrome extension that helps you keep one portable memory layer across AI assistants. It lets you pull memory from one platform, refine it in a single editable Memory.md, and push it into another without reteaching your preferences, background, project context, and working style from scratch.

It currently supports ChatGPT, Claude, Gemini, Grok, Kimi, Mistral, and Copilot. The workflow is intentionally human-in-the-loop, so memory stays visible, reviewable, and under your control instead of becoming a black-box feature locked inside one platform.

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.

Analysis of Memory Sync

Overall verdict

  • I don't have verified information about 'Memory Sync' at mem-sync.kareverie.com, so I can't confirm whether it's good, safe, or effective. This appears to be a niche or possibly obscure product/domain that isn't part of my training data, and I'd strongly recommend independent research before trusting or using it.

  • Making claims about an unknown product's quality without evidence would be misleading

Recommended for

  • Not recommended without further due diligence
  • Suitable only for users willing to independently verify legitimacy, security, and reviews first

Questions & Answers

As answered by people managing Memory Sync and ChainMemory.

What makes your product unique?

Memory Sync's answer

Memory Sync treats AI memory as a portable asset instead of something locked inside one assistant. Instead of asking users to rebuild their preferences and context from scratch in every tool, it gives them one editable Memory.md they can review, refine, and sync across assistants.

The other important difference is the workflow itself: it is intentionally human-in-the-loop. Users can see what is being preserved, edit it directly, and stay in control rather than relying on a black-box memory feature they cannot inspect.

Why should a person choose your product over its competitors?

Memory Sync's answer

A person should choose Memory Sync if they use more than one AI assistant and want continuity without vendor lock-in. It is especially useful for people who already have valuable context stored in one platform and do not want to lose it when they switch tools or experiment with new ones.

Compared with products that keep memory hidden inside a single system, Memory Sync makes the memory layer visible and editable. That means users can carry forward their preferences, project context, and working style with more transparency and control.

How would you describe the primary audience of your product?

Memory Sync's answer

Memory Sync is built for people who actively use AI tools for real work and want their context to travel with them.

That includes founders, operators, developers, researchers, writers, and power users who move between assistants like ChatGPT, Claude, Gemini, and others. In general, the audience values speed, continuity, and control, and does not want to repeat the same preferences and background information in every new AI workspace.

What's the story behind your product?

Memory Sync's answer

Memory Sync came from a simple frustration: people are starting to build real working relationships with AI assistants, but the memory they create is usually trapped inside each platform.

As more users switch between tools for different strengths, they lose preferences, project context, and accumulated background every time they move. Memory Sync was created to make that memory portable, editable, and user-controlled so people can keep continuity across assistants instead of starting over each time.
