Description
Switching between ChatGPT, Claude, and Gemini means re-explaining your context to each one — who you are, what project you're working on, what you already told the last AI. MemoryPlugin gives all of them one shared memory instead, so you stop repeating yourself every time you switch tools.
MemoryPlugin is a cross-platform memory layer maintaining shared context across 21+ AI tools, including ChatGPT, Claude, Gemini, and DeepSeek, with import of years of existing chat history from six sources. It offers full-text search, organized memory buckets, end-to-end encryption, and integrations via browser extension, MCP server, and API. Pricing runs $89/year (Core) or $180/year (Pro), with a 7-day free trial and 14-day refund guarantee.
💬 Our review
The short version: MemoryPlugin solves a real annoyance for anyone who genuinely bounces between multiple AI tools daily, but if you mostly stick to one assistant, the problem it solves barely applies to you.
Against Anthropic's own Claude Projects/Context features (roughly $8/month) and Google's NotebookLM (free tier available), MemoryPlugin's pitch is being platform-agnostic — one memory across every tool, not just one vendor's ecosystem. At $89-180/year, it's worth it if you're a genuine multi-platform power user; single-platform users will get more value from that platform's native memory features instead.
