What are the best MemoryPlugin alternatives?

What is MemoryPlugin, and why look for an alternative?

You might want a different storage location, a local file you control, or memory inside one assistant rather than another subscription. Compare the connection you actually need before paying.

MemoryPlugin shares one memory across 21+ AI tools, including ChatGPT, Claude, Gemini, Grok, Perplexity, DeepSeek, Mistral, Cursor, Claude Code and Codex. It connects through Chrome and Safari browser extensions, a Custom GPT, an MCP server, a TypingMind plugin and an OpenAPI spec. Its FAQ describes a macOS sync app, but the feature list also labels the desktop app coming soon. MemoryPlugin platforms and pricing. Verified 3 November 2026.

MemoryPlugin Core is shown as $89 a year, with the last 500 chat conversations and unlimited memories. Pro is $180 a year, with unlimited chat history and a knowledge graph in early beta. Prices use a $ sign without a currency code. Its 7-day free trial needs a card, and a refund can be requested within 14 days of a charge. MemoryPlugin pricing. Verified 3 November 2026.

How do the MemoryPlugin alternatives compare?

Which alternative suits you?

These are editorial choices, not ratings. If you only use one assistant, start with its built-in memory. If you want local files and are comfortable with setup, consider Basic Memory or the reference server. For a developer integration, compare Mem0 and Supermemory.

Two parts: saved memories, which are stored separately from chat history, and reference chat history, which lets ChatGPT use relevant information from past chats. ChatGPT can decide what to remember, or you can ask it. You view and manage both in Settings, Personalization, Memory. OpenAI says features vary by plan, region, platform and workspace settings. OpenAI Help Centre: Memory FAQ. Verified 21 October 2026.

Memory is on by default for Free, Pro and Max on the web, desktop and mobile apps; on Enterprise an owner allows it. You toggle Memory from chats under Settings, Your Claude (Settings, Memory in the older layout). It is saved as individual topics you can view, edit or delete under Manage. Each project has its own memory: within a project Claude uses that project's memory plus memory from chats outside projects, not other projects' memory, and Use account memory can be turned off per project. Deleting a conversation does not remove memories made from it. Incognito chats are not saved to memory. Searching past chats is on paid plans only. Claude Help Centre: Memory. Verified 27 October 2026.

Basic Memory is open source (AGPL-3.0) and keeps notes as Markdown files on your disk; local use is free. Basic Memory Cloud is shown as $15.00 a month with a 7-day free trial and is hosted on Tigris S3; no region is stated. It connects to Claude Desktop through its MCP config, and Cloud offers one-click connection. Basic Memory on GitHub. Verified 23 October 2026.

The MCP project's reference memory server, @modelcontextprotocol/server-memory, stores a knowledge graph of entities, relations and observations in a local JSON file (memory.json by default). It is MIT licensed and is added to Claude Desktop through claude_desktop_config.json with npx. MCP reference memory server on npm. Verified 23 October 2026.

Mem0 runs a hosted MCP server at https://mcp.mem0.ai/mcp; nothing runs on your machine. Sign-in is in the browser by default, or with an API key, and it needs a Mem0 Platform account. Its setup page lists Claude, Claude Code, Codex, Cursor, Windsurf, VS Code and OpenCode, and does not mention ChatGPT. In Claude you add it as a custom connector. The page does not say which Mem0 plans include MCP. Mem0 docs: MCP integration. Verified 23 October 2026.

Supermemory MCP is a remote server at https://mcp.supermemory.ai/mcp. It uses OAuth, so no API key is needed, and in Claude it is added as a custom connector. Supermemory docs: Supermemory MCP. Verified 23 October 2026.

Where does MemoryPlugin store your data, and does that matter in the UK?

UK storage is one part of your decision, not a substitute for checking processing, access, transfers and retention. Read the provider terms before adding sensitive information.

AI Twin memory storage: UK. Your memory and files are stored in the United Kingdom. AI inference, speech to text and email are processed in the European Union. Two optional lookups, web search and place search, are off until you turn them on.

Can you take your memory with you when you switch?

Keep your original export. A new service may accept only part of it, and an import is not proof that every detail arrived.

3. Import and review

   Check the destination accepts your format. Try a small batch, read what arrived and correct it before relying on it. Bring your exported conversations into your review queue. You choose what to keep. Nothing is saved until you confirm.

   Claude memory is exported from Settings, Your Claude, Manage next to Your memory, or by asking Claude to write out its memories of you verbatim, then copying the text into a file. Claude says imports are experimental and its memory focuses on work-related topics, so personal details may not be kept. Claude Help Centre: Importing and exporting your memory from Claude.

When is MemoryPlugin the better choice?

If you want one memory in web chats across many tools through a browser extension, MemoryPlugin offers a connection AI Twin does not offer. AI Twin connects to outside assistants through MCP connectors only. Assistants that support MCP connectors, such as Claude, can read it with your permission. ChatGPT needs a plan that supports custom MCP connectors with developer mode.
