Give every AI you use a perfect memory.

Letta Memory captures your conversations across ChatGPT, Claude, Perplexity, and Gemini—building a unified memory that follows you everywhere. No more repeating yourself. No more lost context. Every AI just gets you.

Ever notice how you have to re-explain your job, preferences, and past decisions every time you start a new chat? Letta Memory fixes that.

• Remember Everything: Your preferences, projects, and conversation history—automatically saved
• Works Everywhere: One memory across ChatGPT, Claude, Gemini, and Perplexity
• One-Click Context: Inject your memory into any conversation instantly
• Privacy First: Your data stays in your Letta account. We never train on it.

• Chrome Web Store: Coming Soon
• Manual Install: See Installation from Source below

1. Go to app.letta.com and sign up (free)
2. Navigate to API Keys in settings
3. Create a new key and copy it

4. Chat normally—your messages are automatically captured

Click the Letta button before sending a message. Your memory context gets added to the input, giving the AI everything it needs to know about you:

=== RELEVANT MEMORIES FROM LETTA === [user_context] # User Profile - Software engineer working on React projects - Prefers concise, code-focused answers - Currently building a Chrome extension [active_topics] # Active Topics - Letta Chrome Extension development - TypeScript best practices [facts] # Key Facts - Uses VSCode with Vim keybindings - Team uses GitHub for version control === END MEMORIES === <your message here> 

Every conversation is captured and processed in the background. Letta extracts:

• Who you are: Job, expertise, preferences
• What you're working on: Active projects and interests
• Important details: Names, dates, decisions, specific facts
• How you like responses: Format, length, tone

Click the extension icon to access settings:

Enable/disable memory capture for each platform. Useful if you only want Letta on certain sites.

• user_context – Your background, preferences, and goals

• facts – Specific details worth remembering
• conversation_patterns – How you prefer AI responses

Your privacy matters:

• Your data, your account: Everything is stored in your personal Letta account
• No training: We never use your conversations to train models
