## 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 Mouseflow

- "Similar recording patterns; part of the group facing CIPA (California Invasion of Privacy Act) complaints" (Kimi K2, negative prompt, hard negative)
- "variable consent handling and sampling bias from opt-in requirements. EU scrutiny on replay depth." (Grok 4.1 Fast, negative prompt, hard negative)
- "avoid or exercise extreme caution with Hotjar, FullStory, Mouseflow, LogRocket, and Smartlook" (Mistral Small, negative prompt, hard negative)
- "Mouseflow if you want a simpler, usually cheaper tool that still covers both session replay and heatmaps well" (GPT-5.4 mini, direct prompt, first choice)
- "Mouseflow is widely cited as the best value for mid-market teams." (Claude Haiku 4.5, direct prompt, first choice)
- "My Top Recommendation: Mouseflow" (Kimi K2, paraphrase prompt, first choice)
