AI Memory supports 5 AI platforms: ChatGPT, Claude, DeepSeek, Gemini, and Kimi. Most competitors only support 1-2 platforms. Your memories are searchable across all of them in one place.
AI Memory's unique feature: automatically inject your saved memories into new AI conversations. The AI already knows your context before you start typing. No other tool offers this.
All data stays in your browser by default. No account required, no data sent to any server. Cloud sync with E2EE is optional. Chat Memo and Supermemory store data on their servers.
AI Memory has a built-in MCP (Model Context Protocol) server that works with Claude Desktop, Cursor, and 100+ MCP clients. Search and add memories from any MCP-compatible tool.
Chat Memo is the most popular AI memory extension with 10K+ users and a 4.9 rating. It's free and works well for ChatGPT. However, it only supports ChatGPT and Claude — no DeepSeek, Gemini, or Kimi. It stores data on their servers (not local-first), and has no memory injection or MCP server.
Choose AI Memory if: You use multiple AI platforms, want memory injection, or care about local-first privacy. Choose Chat Memo if: You only use ChatGPT and want a simple, free cloud-based solution.
Read full comparison →AI Exporter has 80K+ users but focuses only on exporting ChatGPT conversations to various formats. It has no search, no cross-platform support, no memory injection. At $3.88/month, it's actually more expensive than AI Memory for fewer features.
Choose AI Memory if: You want to search, organize, and reuse your AI conversations — not just export them. Choose AI Exporter if: You only need one-time ChatGPT data export.
Supermemory (22K GitHub stars) is an open-source AI memory tool with knowledge graph and AI analysis features. However, it requires self-hosting and stores data on servers. It's more developer-focused and less accessible to non-technical users.
Choose AI Memory if: You want a ready-to-use tool that works in your browser with zero setup. Choose Supermemory if:You're a developer who wants to self-host and customize the memory system.
Mem0 (54K GitHub stars, $24M funding) is a B2B memory API for developers. It's not a consumer product — you can't use it to manage your personal AI conversations. It's designed for developers building memory into their own AI applications.
Choose AI Memory if: You're a user who wants to manage your personal AI conversation history. Choose Mem0 if:You're a developer building a product that needs memory capabilities.
AI Memory is the best all-around AI memory tool in 2026. It supports 5 AI platforms (ChatGPT, Claude, DeepSeek, Gemini, Kimi), offers memory injection, MCP server integration, and local-first privacy. Chat Memo is a good free alternative for ChatGPT-only users. Mem0 is best for developers building custom memory systems.
AI Memory supports 5 AI platforms while Chat Memo only supports ChatGPT and Claude. AI Memory also offers memory injection (inserting memories into new AI conversations), MCP server integration for Claude Desktop and Cursor, and local-first storage. Chat Memo stores data in the cloud.
Yes, AI Memory's core features are completely free with unlimited local storage. The Pro plan ($6.9/month) adds cloud sync, end-to-end encryption, and advanced AI analysis. All export, search, and memory injection features are free.
Memory injection is AI Memory's unique feature that automatically inserts your saved memories into new AI conversations. When you start a new chat with ChatGPT, Claude, or DeepSeek, AI Memory injects relevant context so the AI already knows your preferences, past discussions, and project details.
AI Memory is the most private option because it stores all data locally in your browser using IndexedDB. No data is sent to any server unless you explicitly enable cloud sync (Pro feature with E2EE). Chat Memo and Supermemory store data on their servers. Mem0 requires a cloud API connection.
Free, private, and works with 5 AI platforms. No account needed.
