Turn daily webpages and videos into effortless English exposure. AI creates i+1 comprehensible input at your level. Ries is an AI English learning Chrome extension. It is not a traditional course. It is not just a translator.
Ries turns the webpages, articles, feeds, and videos you already consume into a low-pressure English learning environment.
You do not need to schedule another class. You do not need to force yourself through long word lists. You do not need to open a separate study app.
You keep reading and watching what you already like. Ries gradually turns part of that content into English exposure you can still understand.
That is the core idea: AI creates i+1 comprehensible input at your language boundary.

Why do many people struggle to improve their English?
Often, it is not a lack of effort. It is a lack of steady exposure.
Vocabulary apps can feel isolated. Courses are hard to keep up with. Full English articles can feel too difficult.
So you know you should learn English, but your real daily English exposure stays low.
Ries changes the environment first.
Instead of asking you to become a perfect student, Ries turns the content you already read and watch into a steady English exposure field.

How Ries helps you learn English with less pressure
1. Learn from webpages you already read
When you read articles, blogs, forums, product docs, news, or search results, Ries can gradually introduce useful English words, phrases, and short expressions into the page.
Most of the content still feels familiar. You can still follow the meaning. But you keep meeting a little more English.
Not a full-page English wall. Not a screen full of unknown words. Just a controlled layer of English near your current level.
2. Learn from videos you already watch
When you watch YouTube or other video content, Ries can help create more English contact inside familiar scenes.
You are not opening a boring textbook. You are learning from content you already care about.
That makes the habit easier to keep.
3. AI adjusts to your language boundary
Everyone has a different English level. One word may be new for you but easy for someone else.
Ries uses your language map and learning behavior to adjust the amount and difficulty of English exposure.
Too easy means no growth. Too hard means you quit.
Ries aims for the middle: mostly understandable, with a little new English.
That is i+1 comprehensible input.
4. Make English part of daily life
Traditional learning asks you to create a separate study block: open a course, open a word app, open exercises.
Ries works inside your normal browsing: webpages, articles, videos, search results, and feeds.
You are already there. Ries slowly turns that environment into a better place for natural English acquisition.
----------------
Who is Ries for?
Ries is useful if you:
If you already browse the web, read content, search for information, and watch videos, that time can become part of your English learning time.
Ries is not trying to make learning heavier. It makes English exposure easier to meet every day.
----------------
How is Ries different from a translator?
Most translation extensions reduce English. They turn English into your native language so you can understand faster.
Ries does the reverse. It turns familiar content into English exposure you can understand.
A translator solves: "I do not understand this right now."
Ries solves: "I do not get enough English exposure over time."
That is why Ries is not just a webpage translator, a dictionary extension, or a subtitle tool.
Ries creates a low-pressure, comprehensible, long-term English input environment inside your normal content.
----------------
How is Ries different from vocabulary apps?
Vocabulary apps often separate words from real context. You may remember a definition, but still miss the word when it appears in a sentence.
Ries keeps words inside context.
You meet English in articles, videos, comments, search results, and real content. The meaning is easier to connect with the scene.
Ries does not only ask you to memorize a word. It helps you meet the word again and again inside familiar content.
