PostHog AI has evolved significantly over its first year, transforming from a basic tool to a comprehensive AI agent capable of complex data analysis and task execution. Key learnings highlight the importance of model improvements, context, and user trust in AI interactions. The platform is now utilized by thousands weekly, offering insights into product usage and error management.

• PostHog AI went from a basic chatbot to an agent handling complex data analysis and task execution over one year, now used by thousands weekly
• Model improvements alone drove significant capability jumps, but context (giving the agent access to the right data/docs) mattered just as much as raw model quality
• User trust had to be earned incrementally—showing reasoning steps, sources, and letting users verify/correct outputs was key to adoption
• Error handling and graceful failure recovery became a major engineering focus as the agent took on more autonomous, multi-step tasks
