MemoryPlugin

What is MemoryPlugin?

MemoryPlugin is a browser extension that adds persistent long-term memory to ChatGPT, Claude, Gemini, and 15+ other AI assistants, allowing users to avoid repeating context across conversations and tools. Made by the MemoryPlugin team, it integrates directly into the web interfaces of major AI platforms without requiring API keys or manual setup.

The tool captures and stores user preferences, project details, coding conventions, writing voice, decision-making context, and other persistent information that gets automatically retrieved and injected into new conversations. Users can manually highlight messages to save them, or enable automatic capture where the system identifies contextually important information without user intervention. Memory is organized into customizable buckets (work, personal, projects) to keep AI responses appropriately scoped. The extension also imports chat history from existing conversations across six platforms, scanning thousands of prior chats to extract relevant context automatically—a capability the product specifically claims competitors don't offer. All stored data is encrypted at rest and never used for model training.

The freemium pricing model offers a basic free tier with limited memory storage, while the Pro plan costs $120 annually (discounted from $240) and includes unlimited memory, chat history import, advanced search, and cross-platform synchronization. The product maintains a 4.5-star rating across 100+ reviews on platforms like Uneed.best and TinyLaunch. MemoryPlugin targets knowledge workers, developers, writers, and researchers who interact with multiple AI tools daily and want context persistence without manual re-explanation. Use cases include maintaining coding conventions across Claude sessions, preserving writing tone and sources across drafts, and keeping financial or goal-related context available for decision-making advice.
