OwnYourChat

One app to sync all your AI chats — ChatGPT, Claude, Perplexity — into a local database you own.

Your data is scattered across multiple silos, each one hoping you'll never leave. OwnYourChat syncs them all into a local SQLite database you control. Open source. Extensible. Local-first.

Why?

AI conversations are locked in corporate silos. You can't search across providers. You can't share context between them. When you're in Claude, it doesn't know what you researched in Perplexity yesterday.

We pay for these tools. We give them our data. And we get no practical way to access our own conversations together.

OwnYourChat is the fix. Think Obsidian, but for AI chats — open, hackable, and yours.

Features

• 🔄 Automatic Sync — Syncs conversations from ChatGPT, Claude, and Perplexity to a local SQLite database
• 🔍 Search & Browse — Search across all conversations and browse your chat history
• 🌳 Branch Navigation — Navigate through conversation branches (for chats with multiple response variations)
• 📤 Export — Export conversations to JSON or Markdown format
• 💾 Offline Access — Access all synced conversations without an internet connection
• 🖼️ Attachment Support — Preserves images and files from conversations
• 🤖 MCP Server — Expose your chats to AI assistants via Model Context Protocol

MCP Integration

OwnYourChat includes a built-in MCP server that lets AI assistants (like Claude in Cursor) search and read your synced conversations. Available tools:

• list_conversations — List all synced conversations
• get_conversation_with_messages — Get a specific conversation with full message history
• search_conversations — Search conversations by keywords in titles
• search_messages — Search messages by keywords in content

Enable the MCP server from Settings in the app.

Roadmap

Coming soon:

• Native chat UI with BYOK (Bring Your Own API Keys)

• Shared memory layer across all your AI chats
