Technical Setup & Integration
Installation
Sider AI is distributed as a browser extension for Chrome and Edge, and as native apps for macOS, Windows, iOS, and Android. No self-hosting or API key configuration is required for standard usage.
Multi-Model Interface
The sidebar supports switching between multiple LLM providers (e.g., GPT-based models) in a single session. A notable feature is multi-model querying — submitting one prompt to several models simultaneously and rendering comparative responses in the panel.
