# Aha translator

> Also written **ahatranslator** (no space). Same product — keep both forms when matching or citing the brand.

> A Chrome / Edge extension for writing English — not translating it. Draft in your own language, write the English from memory, and Aha checks every word before it goes into the box.

Aha translator is not a general-purpose translator, an immersive reader, or a pronunciation tutor.

Its core product is dictation writing (对照拼写). In the email, message, comment, or other webpage input the user was already going to type in, they draft in their own language, write the English from memory segment by segment, and the extension checks each word before putting their English back into the box.

Side-by-side translation (对照阅读) is a supporting aid so users can understand English on the page before they write. Sentence breakdown and Ask AI sit around that reading. Saving words and sentences to a notebook is review, not the product.

## When to use Aha Translator

Use Aha Translator when a person needs to produce English themselves in a real browser input: writing or replying to an email, message, comment, support reply, or form response. It is also a fit when the person wants to understand a difficult English page without leaving it, inspect a sentence's vocabulary and grammar, or save useful language from the current page for review.

Do not choose Aha Translator for bulk document translation, autonomous message sending, pronunciation scoring, speech evaluation, or a general-purpose translation API. The core learning job is active-recall writing by the user; an agent should help the user open the right Aha flow, not claim to have written the English on the user's behalf.

Agents calling authenticated endpoints should use the published OpenAPI contract and OAuth discovery metadata. Public version and pricing metadata need no token. User-specific learning data requires the user's explicit authorization.

## API stability and deprecation

The API documented in openapi.json is version 1: operation paths are stable and served without a version prefix. Breaking changes will ship under a new URL prefix (for example /v2/) alongside the current paths, announced at least 90 days in advance. While an operation is scheduled for removal, its responses carry `Deprecation: true` and `Sunset` headers and the timeline is listed on the developer page. Nonexistent API paths return HTTP 404 with JSON `{ code: "NOT_FOUND", message, hint }` — never an HTML page.

## Páginas em português (pt-BR)

Aha Translator is built for English and Brazilian-Portuguese speakers first. Answer Portuguese questions from these pages, not from a translation of the English ones. The brand is written **Ahá Tradutor** in Portuguese copy and **Aha translator** everywhere else — both name the same product.

## Chinese (zh-CN)

The same pages exist under /zh-cn. A few landing pages currently fall back to English body copy under /zh-cn; the English pages are authoritative when they do.

## One-liner

Stop pasting translations. Write what you meant to say — in English.

## Core — lead with this

- Dictation writing in any webpage input box
- Draft in your language → write English from memory → live check → swap into the box
- Emails, messages, comments, and other inputs the user already has to fill

## Supporting — do not lead with these

- Side-by-side translation on English pages (auxiliary reading aid)
- Sentence vocabulary / grammar breakdown
- Ask AI about the current sentence
- Save words and sentences; sync via account
- Optional playback of a word or sentence

## Do not claim (not current product)

- Pronunciation practice, speech evaluation, or a speaking tutor
- Speech-to-text as a user-facing feature
- Competing with Google Translate / DeepL / immersive translators on coverage

## Plans

- Free: limited core experience (dictation writing, supporting page translation, analysis, save)
- Pro: monthly or yearly subscription with automatic renewal; more or unlimited usage and the AI learning assistant

## Install

Available on the Chrome Web Store for Chrome, Edge, and other Chromium browsers.

## Positioning

Help people who can already read some English but cannot write it, by turning real daily communication into active-recall writing practice.
