What our research says

Sider

Sider puts a chat panel on top of whatever page you're on, so you can ask about an article or PDF without copying it into a separate tab. The catch is that heavier use beyond the free daily cap needs a paid tier, and pricing quoted across review sites is inconsistent, so the entry price is worth confirming before committing.

Pros

  • Works as a sidebar on any web page rather than a separate chat tab
  • Routes one prompt to several models (GPT, Claude, Gemini, DeepSeek, Grok)
  • Ships native apps for iOS, Android, Windows, and Mac plus browser extensions
  • Can chat with PDFs and YouTube videos, not just plain text

Cons

  • Free tier is capped at a small number of daily uses
  • Independent pricing write-ups disagree on exact plan costs depending on where you check
  • No public API for developers

UniJump

A single-purpose shortcut: ChatGPT in an overlay instead of a separate tab, at no cost and with no account of its own. The catch is age - nothing on the site has moved since 2023, and an extension that rides someone else's web session is exactly the kind of thing that breaks quietly.

Pros

  • No signup, no key, no payment - it uses the OpenAI session you already have
  • Cmd/Ctrl+J overlay works on any site rather than needing a dedicated tab
  • In-place paraphrasing of selected text
  • Code is on GitHub, so behaviour is inspectable

Cons

  • Site copyright has read 2023 for three years, with no visible updates
  • Depends on an undocumented web session rather than the official API, so an upstream change can break it
  • Chrome only, and no company or maintainer is named
