Definition

Sider AI is a browser extension that adds a persistent AI sidebar to any webpage, giving users access to chat, translation, summarization, writing assistance, and multiple large language models without leaving their current browser tab.

Overview

Sider AI is designed around a simple observation: much of people's daily AI usage happens while browsing — reading articles, drafting emails, or researching in a browser tab — yet standalone chatbot websites require switching tabs and losing context. Sider addresses this by injecting a collapsible sidebar into the browser itself, accessible on any webpage, that provides chat, translation, and writing tools without navigating away from the page being viewed. A core feature of Sider is model flexibility: rather than being locked to a single AI provider, it allows users to select from multiple underlying large language models (such as offerings from OpenAI, Anthropic, and Google) for a given task, and in some configurations can even query several models simultaneously to compare their responses side by side. The sidebar can read the content of the currently open webpage, enabling functions like summarizing an open article, translating selected text in place, or answering questions about the page's content directly. Beyond general chat, Sider bundles a set of writing and productivity tools: grammar and tone rewriting, quick translation of selected text, YouTube video summarization, and integration with common productivity contexts like email composition and search engine results pages. It is aimed at everyday browser users, students, and professionals who want lightweight, always-available AI assistance layered on top of their existing browsing habits rather than a separate destination site. As a browser extension with page-reading capabilities, it requires users to grant it permission to access the content of visited pages, which is a consideration for privacy-sensitive browsing.
