What is Sider?

Sider installs an AI sidebar in your browser that combines several flagship models with tools built around reading and writing. Its Wisebase feature lets you save pages and files into a personal knowledge base and then chat across everything you have collected. In daily use it summarises pages, translates text in place, explains selections and drafts content without leaving the tab you are working in.

The extension supports group chat, where multiple models answer the same question so you can compare their takes instantly. Free users receive a small daily credit budget; paid tiers add far more credits and unlock the strongest models and research features. For researchers and writers who collect material across the web, Sider's knowledge-base angle sets it apart from generic sidebar assistants.
