Seeking feedback on idea for Chinese practice chrome extension

I'm thinking about making a free chrome extension to help practice Chinese. As you browse the web it would translate specified words into Chinese, to keep your memory fresh. Does the design of this make sense? For example a user might want to remember robot is "机器人" so they would put in robot -> 机器人 and then whenever they encounter robot online they would see the translation. I'm also thinking of a optional mode where it replaces the English word entirely.

I think this is a pretty interesting concept, I think you should check out the chinese popup dictionary chrome extension

It sounds like Toucan.

(Edit: There's a new one called BittyTranslate.)

Yes @becky82, it's similar to toucan  . The difference is my extension allows you to focus on practicing specific words instead of randomly translating words. This gives you more control and makes browsing the web with the extension turned on a nicer experience.

Here's how I'm configuring the extension at the moment:
 

@ez @Tinker25 Thanks for the recommendations! Those aren't the same as what I'm thinking of, but sounds like they could be useful to advanced learners! I'm still at the stage where I'm learning basic vocabulary words.

I agree with @Tinker25—learning Chinese through isolated, unconnected characters isn't the most effective approach. Context is key for really grasping how words and phrases are used in real life

The extension replaces words in the websites you visit, so the words do have context. If you're curious you can give it a try here ~ https://github.com/Almenon/skunk1/releases

And if you're wondering why it's called skunk1, I haven't thought of a name yet 😅. 

I just published an alpha release in the chrome extension store: https://chromewebstore.google.com/detail/replacely/bmlphjmjfcfbkfmbeffkmhbedinpaegj
