Feature Request: AI-powered weekly summary of product trends via Slack

Feature request

Is your feature request related to a problem?

Current insight subscriptions to Slack just send static graphs on a schedule. Customers want something smarter — an AI-generated summary of their week, highlighting global trends and notable changes, rather than just forwarding charts.

Describe the solution you'd like

PostHog AI generates a periodic (e.g. weekly) natural-language summary of product trends, key changes, and anomalies, delivered to Slack. Think of it as a replacement for scheduled insight screenshots — an AI digest instead of raw graphs.

Describe alternatives you've considered

• Current insight subscriptions (graphs posted to Slack on a schedule)
• Manually asking Max to analyze data ad-hoc in the PostHog UI

No implementation files or tests are identified. Start by reviewing the existing scheduled insight subscriptions to Slack and the Max AI flow in PostHog; define the supported summary period, trend and anomaly scope, generation flow, and Slack delivery behavior before identifying the relevant entry points and tests. Done means a documented, tested weekly AI digest replaces or complements scheduled graph posts.
