What is PostHog's plan for custom AI?

PostHog announced on May 27, 2026, its plan to train proprietary AI models using anonymized customer data from its platform. This initiative aims to develop smarter products and new features, such as PostHog Code, to enhance the user experience and improve existing functionalities like session replay. The training for these models is scheduled to commence on June 29, 2026.

Why is PostHog training its own AI models?

PostHog is training its own AI models to make existing products smarter, develop new proactive tools, and improve scalability for features like session replay. This approach also enables synthetic user testing to predict potential issues before product release, ultimately aiming for "self-driving" products that offer proactive solutions.

How will PostHog manage customer data for AI training?

PostHog will manage customer data for AI training by ensuring all data is anonymized and used internally, with no sharing with third-party providers. Users on the EU cloud instance and those with specific legal agreements are opted out by default, while US cloud users are opted in by default but can opt out at any time through their organization settings.

What are the implications of PostHog adopting "sovereign AI"?

PostHog's shift to "sovereign AI" reflects a growing industry trend where companies prefer customized solutions and greater control over proprietary data, moving away from reliance on large hyperscalers. This approach prioritizes internal expertise, data security, and tailored performance, ensuring that AI models are developed and controlled within the company.
