## What the models said about Confluence

- "Search issues: Surfaces archived pages above current ones ... Cost creep: Atlassian pricing changes have frustrated many users" (Kimi K2, negative prompt, soft negative)
- "Sluggish performance on large pages, steep learning curve, clunky permissions, dated editor, search degradation at scale." (Grok 4.1 Fast, negative prompt, soft negative)
- "not suitable for public help centers and is often better treated as an internal wiki than a customer support KB" (Perplexity Sonar, negative prompt, soft negative)
- "Choose Confluence if you're focused on internal team documentation and already use Jira" (Kimi K2, direct prompt, first choice)
- "Often the top pick for mid-sized teams... Confluence leads for B2B collaboration" (Grok 4.1 Fast, direct prompt, first choice)
- "Notion free + Confluence free 10-user are the most commonly recommended" (Muse Glimmer 30B, budget prompt, first choice)
