One subscription now offers paid-tier access to GPT-5, Claude 4.5 Sonnet, Gemini 2.5 Pro, and Perplexity Sonar, currently promoted in one- and three-year deals for $29.99 and $69.99 respectively.
ChatOn is an AI aggregator app with over 100 million downloads and a 4.7 App Store rating across 268,000 reviews. It routes queries to whichever model you select without requiring separate accounts at each lab. A StackSocial promotion offers a one-year subscription for $29.99 (regular $39.99) or three years for $69.99 (regular $119.99). Beyond text chat, the app includes AI image generation, PDF and document processing, OCR, real-time web search with cited sources, translation, and voice input, all synced across iOS, Android, and web.
Worth being clear on what you are actually getting: ChatOn is not a full replacement for individual Pro accounts. You will not get early access to lab-specific features, but you do get better-than-free model capability on a flat-rate subscription with no monthly credits that expire if your usage drops.
The math works if you are already juggling two or three separate AI bills. If one model handles everything you need, this is a bundle solving a problem you do not have.
