## What the models said about Microsoft SharePoint

- "SharePoint if you need a simple, low-maintenance intranet" (Perplexity Sonar, negative prompt, hard negative)
- "Great for document management but frustrating as a full intranet—90% of projects reportedly underperform without heavy customization" (Grok 4.1 Fast, negative prompt, soft negative)
- "Out of the box, SharePoint is a document repository, not an intranet... Who should avoid it: Organizations with small HR/IT teams" (Qwen 3.7 Flash, negative prompt, soft negative)
- "For most companies on a tight budget, Pebb (free tier) or Microsoft SharePoint/Teams (if you already use Microsoft 365) offer the best value-to-cost ratio." (DeepSeek V4 Flash, budget prompt, first choice)
- "Start with SharePoint or Google Sites. It costs $0 extra and aligns with security protocols" (Gemini 3.5 Flash, budget prompt, first choice)
- "SharePoint is often the best value, because it's included in many Microsoft plans" (GPT-5.4 mini, budget prompt, first choice)

## What the models said about Slack

- "However, if you are hiring younger talent or have a "customer-experience first" sales culture, stick with Slack." (Qwen 3.7 Flash, paraphrase prompt, first choice)
- "Slack is the better choice if your company runs on Google Workspace or is more tech-forward" (DeepSeek V4 Flash, paraphrase prompt, first choice)
- "For most mid-sized B2B companies, Slack or Microsoft Teams are the safest choices" (Claude Haiku 4.5, paraphrase prompt, first choice)
