The Phnom Penh Post4 min read

Cambodia’s young farmers are turning to technology to their from a changing .

Try it — tap an underlined word.

Sound familiar?

The dictionary gives six meanings

And none of them fit the sentence you’re reading. You guess, and you guess wrong.

Graded readers are boring

“Tom goes to the market.” You’re an adult. You want the news, football, and technology — the real internet.

Monday’s words are gone by Friday

You looked it up, you understood it, you forgot it. Without review at the right moment, words don’t stick.

How it works

Three steps between you and reading real English

Read anything

News, blogs, song lyrics, homework — if you can read it, Rian can teach it.

Paste any link

Tap a word

The AI reads the whole sentence first, then explains that word in your language.

harvest → ផលដំណាំ

Remember it

Saved words come back for review right before you’d forget them.

Good → due in 3 days

Every saved word makes the next article easier.

Built for your language

Big apps translate at you. Rian explains in your language.

Most learning apps are built for European languages and treat everyone else as an afterthought. Rian launched with Khmer first — and explains English in 29 native languages.

Spaced review

Words come back right before you’d forget them

Every word you save is scheduled with FSRS — the modern spaced-repetition algorithm used by serious memory tools. No decks to manage, no settings to learn.

  • Each word keeps the sentence you found it in — context is what makes it stick.
  • Reviews take minutes, not hours: only the words that are due today.
  • Grade honestly — Again, Hard, Good, Easy — and the schedule adapts to you.

harvest

ផលដំណាំ

“…protect their harvest from a changing climate.”

Why Rian exists

I built Rian because every English app I tried explained English in English — or in Spanish, or French. Never in the language my family actually speaks. Rian is the reader I wished existed: real articles, real context, explained in your own language — starting with mine, and now in 29.
— Dara, founder of Rian, Phnom Penh

Rian explains English in 29 native languages — starting with Khmer, Vietnamese, Thai, Lao, and Burmese, plus Chinese, Hindi, Arabic, Spanish, and more. The full list is above.

Duolingo teaches courses — lessons someone else wrote, in a fixed order. Rian is for reading the real internet: you choose the article, and Rian helps you understand and remember it. Many people use both.

A dictionary shows you every meaning; Google Translate replaces the sentence. Rian reads the sentence first and explains the one meaning that fits — then saves it with that context so you can review it later.

You need a connection for new translations, since the AI reads each sentence live. Words you’ve already saved are on your device for review.

Yes — subscriptions run through the App Store, so you cancel in your phone’s settings in about ten seconds. No emails, no retention tricks.
