What is PostHog AI?
PostHog combines many tools typically used separately — event analytics, session replay, feature flags, A/B testing, user surveys, and error tracking — into a single open source platform self-hostable for complete data control. The all-in-one approach reduces integration complexity. AI features include natural language chart creation and insights from user data. The LLM analytics toolkit allows tracking AI product usage — token costs, completion rates, and user satisfaction with AI features — within PostHog. The cloud version is generous at 1 million events per month free. For engineering-led companies with privacy concerns or data sovereignty requirements, PostHog is the strongest choice.
How PostHog AI works
PostHog AI runs as ai search software built around text and data workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on web, ios, and android, with API access for teams that want to embed it into their own products.
