### 1/5 — Worst Buy Ever for NOTHING

*2026-02-06*

If you want to put 2 dollar in trash, purchase it. Oh my what, what a scam. It just redirects you to ChatGPT and it also doesn’t work more than half of time. Not even worth to try for free let alone purchasing it.

### 5/5 — Perfect

*2025-10-31*

I use this extension every single day. Allows me to stay on the webpage I need help with. Great job!

### 1/5 — Its not what I wanted

*2025-09-15*

All it does is just redirect you to Chat GPT and half the time it can’t even access the site.

### 1/5 — ただのリンクです

*2025-06-27*

拡張機能のボタンを押すとChatGPTのチャット画面に飛ぶだけの機能。ブックマークをクリックするのと同じです。安いからまだ許せますが、他に騙される人が出ないようにレビューしました。

### 5/5 — Perfect ChatGPT extension

*2025-02-26*

After trying tons of extensions, this is the AI extension I was looking for. Just pay once and then the extension leverages your existing chatGPT account. Very useful to summarize, fact check or even translate text of pages very quickly. I recommend it!
