Sider AI is a cross-platform browser extension (Chrome, Edge) and native app (Mac, Windows, iOS, Android) that integrates multiple large language models into a unified side panel interface. It supports multi-model querying — allowing users to send a single prompt to multiple models simultaneously and compare responses. The extension hooks into the active browser tab to enable context-aware actions like page summarization, OCR from images, PDF chat, and deep reading. Wisebase acts as a persistent, searchable knowledge layer that stores clips, chats, and documents grounded in original sources.
