Sider integrates as a browser sidebar and cross-platform agent that brings LLM capabilities into whatever page or editor you’re using. Key ways it connects:
- In-page sidebar & extensions: auto-discover relevant web pages, highlight key passages, generate notes and cited reports directly from the page.
- Multi-model & multimodal routing: works with ChatGPT, Claude, DeepSeek, Gemini and other models to power different tasks.
- Knowledge sync & chat: saves findings into a personal Wisebase so you can chat with, expand, and convert notes into drafts.
- Cross-platform caveats: features differ across extension, web, mobile and desktop; extension↔mobile history sync is available today, desktop sync is coming.
There’s also an "artifacts" preview for rendering HTML outputs inside chat controls.
