How Moltbot Keeps Your Data Private
The Architecture
ChatGPT:
You → OpenAI Servers → AI Processing → Response
(data stored) (training?)
Moltbot:
You → Your Computer → AI Provider → Response
(data stays) (only prompt sent)
What Stays Local
- All message history
- Conversation context
- Your configuration
- Personal preferences
What’s Sent to AI
Only the current prompt — no history, no metadata, no personal identifiers.
