AI Memory supports 6 AI platforms: ChatGPT, Claude, DeepSeek, Gemini, Kimi, and Grok. 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.
Rethread is a new 2026 competitor offering E2EE sync, a prompt marketplace with 117+ templates, and daily brief summaries. It supports 6 platforms. However, it has no Web App, no MCP Server, and no AI-powered analysis. It's a pure browser extension with limited organization features.
Choose AI Memory if: You want a Web App + Extension combo, MCP server integration for Claude Desktop/Cursor, and AI-powered conversation analysis. Choose Rethread if: You primarily need E2EE cloud sync and a prompt template library.
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.
Memobase (2,700+ GitHub stars) introduces "Dream Phase" — a background memory distillation process that automatically extracts structured knowledge from conversations. It's fully open-source and self-hosted, with a hybrid knowledge graph combining vector and graph retrieval.
Choose AI Memory if: You want zero-config setup, a Chrome extension for auto-capture from 6 AI platforms, and a managed service. Choose Memobase if:You're a developer who wants automatic memory distillation and full self-hosting control.
Read full comparison →Core (1,600+ GitHub stars) positions itself as "Your Personal AI OS" — combining memory graphs, shareable knowledge, and user-owned data. It's open-source with MCP support and focuses on building a persistent, evolving understanding of your preferences.
Choose AI Memory if: You want a polished consumer experience with Chrome extension, 6-platform support, and a generous free tier. Choose Core if: You want a self-hosted personal AI OS with shareable memory graphs.
AI Memory is the best all-around AI memory tool in 2026. It supports 6 AI platforms (ChatGPT, Claude, DeepSeek, Gemini, Kimi, Grok), offers memory injection, MCP server integration, and local-first privacy. Rethread offers E2EE sync and a prompt marketplace. Chat Memo is a good free alternative for ChatGPT-only users. Mem0 is best for developers building custom memory systems.
AI Memory supports 6 AI platforms (including Grok) 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. AI Memory Pro ($9.99/month or $79/year) adds unlimited conversations, AI-powered analysis, cross-platform sync, and encrypted cloud storage. A Lifetime deal is available at $79 one-time payment — pay once, use forever. 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 stores your data in an isolated session on our server — only you can access it with your session cookie. No tracking, no data selling. The Chrome extension can also store data locally in your browser using IndexedDB. Unlike Chat Memo and Supermemory which store data on their servers, AI Memory ensures session isolation so your conversations are private. Mem0 requires a cloud API connection.
Free, private, and works with 6 AI platforms. No account needed.
