## What the models said about PostHog

- "PostHog does offer data scrubbing features, but I was recently surprised to see their announcement about integrating AI to analyze session replays on behalf of users. This raises a red flag" (Muse Glimmer 30B, negative prompt, soft negative)
- "If you enable network capture, scrutinize it separately from replay masking: requests and responses can contain sensitive headers or bodies" (GPT-6 Luna, negative prompt, soft negative)
- "I'd generally recommend PostHog if you want the best balance of visitor behavior analytics, product analytics, and session replay in one place" (GPT-5.4 mini, paraphrase prompt, first choice)

## What the models said about Contentsquare

- "Heavy enterprise pricing and complexity; overkill for most mid-market needs" (Kimi K2, direct prompt, hard negative)
- "enterprise tools only if you need deeper product analytics, governance, or enterprise workflows, because they're generally much more expensive" (GPT-5.4 mini, budget prompt, soft negative)
- "without paying the $50k+ annual contract values required by enterprise-only suites (like FullStory or Contentsquare)" (Gemini 3.5 Flash, direct prompt, soft negative)
- "my default recommendation is Contentsquare if you want the most complete, scalable experience-analytics platform" (GPT-5.4 mini, direct prompt, first choice)
- "Go with FullStory or Contentsquare for deep session replay and journey analytics." (GLM 4.7 FlashX, comparative prompt, first choice)
- "The sweet spot is usually FullStory, Contentsquare, or LogRocket" (DeepSeek V4 Flash, scale prompt, first choice)
