Why "curated" here instead of "selected"?
"Curated" implies expert judgement — someone picked it and organised it. "Selected" just means chosen; by whom or on what basis, it never says. Here it vouches for the data quality.
What about "hand-picked"?

Reading English is where every learner gets stuck: a word you do not know, a sentence that does not make sense, and suddenly you are pasting text into a translator instead of reading. Aha Translator removes that friction — translation sits right under the original, so you never break the flow.

But reading is only half of learning. Once you understand, the next step is writing it yourself — because understanding is not using.

Why it works

Each step turns a translator habit into a writing habit — and writing is where learning happens.

SIDE-BY-SIDE

Side-by-side translation

Select an English sentence and Aha shows the translation directly below the original, paired with matching colors so your eyes never lose the thread. No dictionary, no separate tab — just keep reading.

  • Read articles, news and emails without getting stuck
  • Translation right under every sentence — no more translating line by line
  • Keep reading instead of quitting when it gets hard
UNDERSTAND

Understand every sentence

When a sentence is hard, the breakdown explains it. Every key word comes with its definition and part of speech, and the grammar structure is laid out so you understand why it works.

  • Word lookup with definitions and parts of speech
  • Grammar breakdowns that explain why it works
  • Ask the AI about the exact sentence
CLOSE THE LOOP

From reading to writing

Reading English is not the same as knowing it. The moment you try to write a sentence yourself, every word you only recognized disappears. That is where dictation writing comes in.

  • Reading builds recognition; writing builds production
  • Turn what you read into what you can write
  • Close the loop with dictation writing

Read it, then write it

Reading is where writing starts. Go to the other half of the loop.

Frequently asked questions

What is side-by-side translation?

Side-by-side translation shows the translation directly under each original sentence, paired with matching colors, so you read English without breaking flow. It is the opposite of pasting text into a separate translator.

How do I read English articles without a dictionary?

Highlight any sentence and Aha shows its translation and breakdown — key vocabulary, parts of speech and grammar — right on the page. You understand in context instead of stopping to look up every word.

How do I read English news without translating every line?

You do not need to translate every line. Aha translates only the sentences you highlight, so you read the parts you understand and get help exactly where you are stuck.

What does the sentence breakdown cover?

Every sentence gets key vocabulary with definitions and parts of speech, plus a grammar structure breakdown. If that is not enough, keep asking the AI about that exact sentence.

How does reading connect to writing?

Reading builds recognition; writing builds production. Aha closes the loop: read with translation, understand with breakdowns, then write it yourself from memory — because understanding is not using.
