I've also been using the LLM in Posthog and it has been impressive. I need to check if I can also plug a MCP/Skill to my actual claude code so that I can cross reference the data from my other data source (stripe, local database, access logs etc.) for in depth analysis
This might be up your alley - have Posthog and a ton of other SaaS tools connected so you can run analysis across quant/qualitative data sources: https://dialog.tools
