Sider review

Sider has grown from a ChatGPT sidebar into a broader AI workspace, and YouTube Summary is one of its listed premium features. Every plan includes every feature: chat with models from OpenAI, Anthropic, Google, DeepSeek and others, summaries of long articles, translation of webpages, PDFs and images, Sider Hand for automating tasks across real websites, and tools for generating images, videos and slides. Plans differ by monthly credits and cloud computer power, from Nano at US$10 a month to Lite at US$25, Pro at US$50 and Max at US$100. Lite and above include a dedicated cloud computer that runs Sider Hand around the clock. Yearly billing takes up to 17% off and adds 20,000 bonus credits a month. For video summaries alone, this is the most expensive entry point on the list, and the public pricing page does not show how many credits each plan includes.
