## What the models said about Demio

- "Platforms with poor reliability scores (Demio, BrightTALK)" (GLM 4.7 FlashX, negative prompt, hard negative)
- "Most webinar platforms (like GoToWebinar or Demio) use tiered pricing, meaning the more people register for your webinars, the more you have to pay." (Gemini 3.5 Flash, budget prompt, soft negative)
- "attractive interface, but reported audio/connection issues, tricky HubSpot integration, and data export lockout after cancellation" (DeepSeek V4 Flash, negative prompt, soft negative)
- "I'd recommend starting with Demio if budget is a consideration, or Goldcast if webinar quality and brand presentation are critical" (Kimi K2, paraphrase prompt, first choice)
- "I'd recommend starting with WebinarGeek or Demio as they offer the best balance of features, pricing, and ease of use" (GLM 4.7 FlashX, paraphrase prompt, first choice)
- "I'd recommend starting with Demio for its balance of affordability, ROI tracking, and ease of use" (MiniMax M2.5, direct prompt, first choice)

- "BigMarker (poor offer pop-ups, glitchy screen sharing, pricey)" (Grok 4.1 Fast, negative prompt, soft negative)
- "Supports live, simulive, automated, and on-demand webinars natively from one platform, and fits mid-market to enterprise teams" (Claude Haiku 4.5, direct prompt, first choice)
- "Choose BigMarker or ON24 if you're running large-scale, highly controlled, analytics-heavy enterprise events" (Perplexity Sonar, paraphrase prompt, alternative)
