PostHog announced plans to train AI models on customer data to build more proactive, self-driving products. The analytics platform aims to enhance existing features like session replay analysis and develop new capabilities such as PostHog Code, currently in beta. EU users are opted out by default, while US customers will be opted in unless they have specific agreements preventing model training.

The company wants to use anonymized data from PostHog instances to improve AI-powered features like their installation wizard and MCP. PostHog AI can already detect issues in session replays but struggles with scaling. Training on underlying data could make these features more powerful at scale, enabling synthetic user testing to identify potential problems before shipping to production.

PostHog emphasizes transparency about their data usage plans, which will begin on June 29. Users can opt out at any time through org settings. The company states they won't sell or send user data to third-party providers. Those who opt out won't have access to new features dependent on this training data, creating a clear tradeoff between enhanced functionality and data privacy.
