What is Sider?
Sider is an AI browser assistant for reading and writing that lives as a sidebar inside Chrome and Edge, giving users instant access to ChatGPT 3.5/4, Claude 3, and Gemini 1.5 Pro without switching tabs or copying content between applications. Whether you are reading a research article, watching a YouTube video, or drafting a document, Sider's sidebar interface activates in context — summarizing the current page, answering questions about its content, or assisting with writing in a separate panel. For knowledge workers who spend their day across dozens of browser tabs, the constant context switching between an AI tool and the content they are analyzing represents a genuine productivity tax. Sider addresses this by embedding the AI layer directly in the browsing experience — a professional can highlight a dense legal document, press a keyboard shortcut, and receive a plain-language summary within seconds, without opening a separate tab, pasting content, or re-establishing context in a standalone chat interface. The multi-model architecture is a meaningful differentiator: users can route different task types to different models within the same session — using Claude 3 for nuanced document analysis, switching to GPT-4 for creative writing, and querying Gemini for web-connected research — without managing separate subscriptions. Compared to Merlin AI, which offers similar browser integration, Sider's wider model roster and image generation capability give it a broader functional range. Keep in mind that Sider's full feature set is currently available only on Chrome and Edge — users of Firefox, Safari, or other browsers cannot access the extension.
