  • Long documents: Claude (200K context)

Sider works best when you reference the current page:

“Based on this article, what are the implications for [topic]?”

Save prompts you use frequently:

  • “Translate to Korean, maintain formal tone”

Privacy & Security

Sider handles your data with:

  • End-to-end encryption

Common Issues

“Sider isn’t seeing my page”

  • Ensure extension has permission for the site
  • Try refreshing the page
  • Check if site blocks extensions

“Slow responses”

  • Try a faster model (GPT-4o vs GPT-4)
  • Check query complexity
  • Verify internet connection

“Limited features on some sites”

  • Some sites (banking, etc.) block extensions
  • Use screenshot/copy for these cases
