What our research says

OmniSide

OmniSide bundles a handful of everyday AI tasks, such as chat, summarizing, translating and OCR, into one sidebar so a user is not switching between separate extensions. Because no paid tier or usage limit is disclosed, it is unclear how the product sustains itself or what happens if usage is heavy.

Pros

  • Combines chat, summarization, translation, writing help and OCR in a single sidebar
  • Supports chatting with multiple AI models from the same panel
  • No cost shown anywhere on the marketing site for any listed feature

Cons

  • No pricing, usage limits or terms are disclosed, making it hard to judge long-term reliability
  • FAQ references pricing questions without actually answering them
  • No detail on which underlying AI models power the chat or OCR features

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
