Sider — Best Overall AI Sidebar

  • Summarize any page
  • Explain selected text
  • Translate content
  • Generate and edit text
  • Analyze images on pages

Why It’s Great

Installation Tips

Performance Management

  • Disable extensions you’re not actively using
  • Review permissions periodically

Privacy Considerations

  • Extensions can see your browsing data
  • Avoid using sensitive AI extensions on banking/healthcare sites
  • Check what data each extension collects
  • Use incognito mode to disable extensions temporarily

Work Computer Considerations

  • Check your company’s policy on browser extensions
  • IT may block certain extensions
  • Some companies require pre-approval
  • Be cautious with confidential data in any extension

The Bottom Line

AI Chrome extensions bring AI assistance into your existing workflow without friction. Instead of switching to ChatGPT or Claude, you get AI help right where you’re working.

Start with Sider — It’s the most capable and flexible option.

Add Grammarly — Passive writing help with zero effort.

Add Perplexity — When you need to research or fact-check.

Beyond that, install based on specific needs. More extensions isn’t better — a few well-chosen tools beat a cluttered browser.

The goal isn’t to AI-ify everything. It’s to remove friction from tasks that benefit from AI assistance, so you can focus on work that requires your human judgment.
