The Best AI Chrome Extensions in 2026 (and When to Skip Them)
Almost every AI extension promises the same three things: summarise this page, rewrite this text, answer this question. The difference is how little friction they add and how much data they ship off your machine.
Our picks
Each one solves a different job, so it's fine to run one sidebar and one specialist.
- 1
Monica AI
The best general sidebar: page summaries, translation, rewriting and chat with multiple models behind one shortcut.
- 2
YouTube Summary with ChatGPT
Turns a 40-minute video into a skimmable transcript summary. Ideal for research and tutorials.
- 3
Wordtune
Strongest rewriting suggestions when you already know what you want to say but not how to say it.
- 4
Grammarly
Less flashy than the AI sidebars, but the most dependable everyday correction layer across every text box.
When to skip an AI extension
If it requests access to all sites and sends page content to an unnamed API, skip it — that's your inbox, your CRM and your bank dashboard. Also skip anything that duplicates a feature your browser or existing tools already have; two AI sidebars fight for the same shortcut and double the memory.
Frequently asked questions
Are AI Chrome extensions safe for work accounts?
Only if you know where page content goes. Prefer extensions with a published privacy policy, an opt-in page-reading model, and a paid tier — free unlimited AI usually means your data pays for it.
Which AI extension is best for summarising pages?
Monica AI handles general web pages best, while YouTube Summary with ChatGPT is stronger for long videos.
