Overview
Sider places an assistant inside the browser and also provides web, mobile and desktop applications. It can summarize, explain or translate a webpage, PDF, image or video, then compare responses from several models.
The platform adds browser automation, research, file analysis, image and video generation, presentation creation and transcription tools. Users can therefore move from reading to production without leaving their usual environment.
The free tier includes a limited credit allowance. Paid plans mainly add capacity and cloud computing power; they do not turn Sider into a general public API for embedding models in third-party products.
