ChatHub is subscription-only from day one — $14.99/month Basic or $24.99/month Pro. PLAI.chat has an unlimited free tier with no signup, plus pay-per-use for premium models.
ChatHub curates around 20+ models (GPT-5, Claude, Gemini, DeepSeek, and a few more). PLAI.chat gives you 300+ via OpenRouter, including specialized models (coding, reasoning, vision) you won't find on ChatHub.
ChatHub Pro is $24.99/month whether you send 10 or 10,000 prompts. PLAI.chat is pay-per-use — most users spend $2–5/month, far less than either ChatHub tier.
PLAI.chat stores conversations in your browser's local storage by default. ChatHub stores them on its servers. PLAI.chat also offers Zero Data Retention mode.
PLAI.chat renders Mermaid flowcharts and diagrams inline with SVG export. ChatHub does not support inline Mermaid rendering.
ChatHub's 6-panel side-by-side view is great on desktop but cramped on mobile. PLAI.chat's sequential comparison ("Run same prompt on...") works equally well on phones and tablets.
