Zhiliao AI is a browser sidebar giving access to GPT-4, ChatGPT-4o and Gemini 1.5, plus Xiaohongshu caption generation, AI search, an image recognizer and translation, across web, desktop and Android. Free usage credits build up through daily check-ins and friend referrals, with paid upgrades available for a larger quota. The developer states the extension is no longer updated and recommends switching to GPT, DeepSeek or Qwen directly, so anyone wanting ongoing support or new features should treat that recommendation seriously.
