Tap any text
Tap the bubble, then tap a word or a sentence. The translation appears instantly in a small card.
Android · Free
Translate any text, over any app
A small floating bubble that translates what is on your screen, right where it is: social media, chats, the browser, games and manga. No copying, no switching apps.
- 130+ languages
- Works offline
- No ads, no tracking
Everything you need, without leaving the app you are in
Tarjuman draws the translation over the original text, so reading in another language feels natural.
Full-page translation
Translations are drawn over the original text, exactly in place, and update automatically as you scroll.
Text inside images
On-device OCR reads text in photos, manga, menus and games. Select an area or let Tarjuman find it.
Live area translation
For burned-in video subtitles and game text: select the area once and it keeps translating by itself.
Translate what you type
Write in your language, tap “Replace text”, and send the message in any language, right from the input field.
Dictionary and pronunciation
Meanings by part of speech, definitions, examples, phonetics and read-aloud for the original and the translation.
My words
Save any word with ☆ and review it later with flashcards. An optional history stays on your phone only.
Your bubble, your rules
Size, opacity, a Quick Settings tile, and automatic hiding in the apps you choose, such as banking apps or games.
How it works
- 1
Turn on the service once
Tarjuman uses Android's Accessibility Service to read the text on screen. A clear disclosure screen explains exactly what is read, when, and why.
- 2
Tap the bubble
A blue bubble floats over every app. Tap it, then tap any text, or long-press it to translate the whole page.
- 3
Read in your language
The translation appears in place. Copy it, listen to it, save the word, or peek at the original with a long press.
Three translation engines
Pick the one that fits the moment. Tarjuman switches automatically if one of them fails.
130+ languages and a dictionary for single words. Needs an internet connection.
On-device
Download a language once (about 30 MB) and translate anywhere, with automatic language detection. Nothing leaves your phone.
Claude AI
Understands slang, idioms and context, and adds an “Explain” button that tells you what a phrase really means.
Private by design
Tarjuman has no account, no servers and no analytics. Here is what that means in practice.
- The screen is read only when you ask for a translation. Never in the background.
- Screenshots are processed on your phone and deleted immediately. They are never uploaded.
- Only the text you ask to translate is sent to the engine you chose, over an encrypted connection.
- History and saved words are optional and stay on your phone, excluded from backups.
- You can withdraw consent and turn the service off at any time, from inside the app.
Frequently asked questions
Why does Tarjuman need the Accessibility Service?
It is the only Android API that lets an app read the text shown inside other apps and draw over it. Tarjuman uses it solely for translation, never reads passwords, and shows a full disclosure screen before you turn it on.
Does it work without internet?
Yes. Choose the “On-device” engine and download the language pack once (about 30 MB). Translation then happens entirely on your phone.
Which apps does it work with?
Any app that shows text: Facebook, X, Instagram, WhatsApp, Telegram, YouTube, browsers, games and manga readers. Text inside images is read with on-device OCR.
Is Tarjuman free?
Yes. There are no ads and no in-app purchases. The optional Claude engine uses your own Anthropic API key, billed by Anthropic to your account.
Can I hide the bubble in some apps?
Yes. Choose the apps in which the bubble hides itself, for example banking apps, games or video players. It comes back automatically when you leave them.
Which Android version do I need?
Android 8.0 or newer. Reading text inside images (OCR) needs Android 11 or newer.
