Which AI chatbots are ad-free? It's time to look beyond ChatGPT

The article compares ad strategies across leading AI chatbots: OpenAI is testing clearly labeled, non-intrusive ads for Free/Go ChatGPT users; Anthropic pledges Claude will remain ad‑free; Google plans Gemini ads by 2026 and is testing ads in Search’s AI Mode; Microsoft Copilot already integrates Microsoft Advertising; Perplexity shows sponsored follow‑ups and side media; xAI’s Grok is expected to include ads within or alongside responses; and Meta AI keeps chats ad‑free but uses interactions to personalize ads elsewhere—making Claude the only major assistant with an explicit no‑ads‑in‑conversation commitment right now.
