Frequently asked questions about Prompt Engineering Tools

Real answers from real users, pulled straight from launch discussions, forums, and reviews.

  • 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.
