Can I use Ditto with ChatGPT, Claude, Cursor, or other AI tools?

Yes! Ditto implements the Model Context Protocol (MCP) as both a server and client. Connect Ditto's MCP server to ChatGPT, Claude, Claude Code, Cursor, Cline, Windsurf, or any MCP-compatible tool to give them access to your persistent memory and knowledge graph. Your memory works across all your AI tools seamlessly.

How is HeyDitto different from other AI assistants?

Unlike traditional AI assistants that treat each conversation as isolated, HeyDitto builds a comprehensive understanding of who you are through sophisticated memory systems and by getting to know your unique personality. It learns your preferences, remembers your context, and adapts its responses to match your communication style and decision-making patterns. Plus, with bidirectional MCP integration, your memory works across ChatGPT, Claude, Cursor, and any MCP-compatible tool.

What is HeyDitto's memory system and how does it work?

HeyDitto's agentic memory system functions like an artificial hippocampus, storing and organizing all your interactions into a rich knowledge graph. It includes short-term memory (configurable 0-10 recent conversations) and sophisticated long-term memory with up to 5 levels of hierarchical chaining. The system uses vector-based similarity matching and semantic search to surface the most relevant information when you need it, automatically categorizing memories by Subjects, People, Places, Things, and Ideas.

How does HeyDitto get to know my personality?

HeyDitto develops a deep understanding of who you are through natural conversations and shared experiences. By analyzing your communication patterns, preferences, and decision-making style across multiple personality frameworks, it builds a comprehensive picture of your unique nature. This happens organically as you chat - no formal questionnaires needed. HeyDitto learns your core qualities, how you see the world, and your connection style, enabling it to respond in ways that feel natural and authentic to who you are.

Which AI models does HeyDitto support?

HeyDitto provides access to the best AI models from leading providers including OpenAI (GPT-5.2), Anthropic (Claude Sonnet, Haiku), Google (Gemini 3 Flash/Pro, Gemini 2.5 Flash), Moonshot (Kimi K2.5), xAI (Grok-4), and more. You can switch models mid-conversation, and transparent per-token pricing via the Ditto Token system means you always know what you are paying.

How does HeyDitto ensure the privacy and security of my data?

HeyDitto takes your privacy seriously with a privacy-first design that processes data locally where possible. All conversations and memories are protected with industry-standard security measures, and we maintain strict confidentiality protocols. Your personal information is never sold or shared with third parties. We use transparent data handling practices and give you full control over your memory retention and data management.
