Frequently asked questions

OffKin is an offline translator, AI assistant, document converter and QR code scanner for Android. Everything runs right on the phone, without internet.

Only once: to download the AI model and languages. After that OffKin works fully offline, even in airplane mode.

No. Translations, chats, documents and codes are stored only on your phone and are never sent anywhere. No sign-up or account is needed, and we don't collect data. See the privacy policy for details.

Yes, the Basic version is free forever: the offline translator, the QR code scanner and documents without AI. The first month — all Pro features for free, no card needed. See Basic and Pro.

Android 11 or newer. The translator without AI, the converter and the scanner work on any such phone; AI needs at least 4 GB of RAM. See Phone requirements.

OffKin is currently available only for Android. An iPhone version is planned.

Download the languages you need once (Settings → "Offline languages"). After that OffKin translates text and voice right on the phone, without internet or mobile data.

Yes. Tap "Speak" — OffKin recognizes the speech, translates it and can read the translation aloud. It all happens on the phone.

In the Translator, choose "My language" and "Other person's language". Each person taps "Speak" on their side, and OffKin translates the conversation both ways.

Yes: the translator works without roaming or Wi-Fi — on a plane, in the mountains, abroad. For a trip there is "Pro for a month" — one payment, no auto-renewal.

15 languages: English, Russian, Ukrainian, Spanish, German, French, Italian, Portuguese, Polish, Turkish, Arabic, Hindi, Japanese, Korean and Chinese. Text and voice translation work in all of them.

Yes: select the text and choose "OffKin: translate" — or "Share" → OffKin. The text is translated right away in the Translator.

Yes. In OffKin the neural network runs right on the phone: it is downloaded once, and then works without internet, even in airplane mode.

It answers questions in a free chat. You can ask by voice and listen to the answer. No servers, no sign-up.

No. Questions and answers are processed on the phone and are never sent anywhere, so OffKin suits personal and work topics.

You can choose the "With the AI model" translation method. In Pro, the AI model translates documents and photos — it reads the text in the picture itself.

It works without a connection, and your data stays with you. But the model is compact: it doesn't know recent news and can make mistakes — check important information.

At least 4 GB of RAM for the light model and 6 GB for the accurate one. The app checks the memory itself and offers only the models that fit. On phones with a GPU, "GPU acceleration (MTP)" is available.

Open "Documents" and choose a file: PDF, DOCX, TXT, HTML, MD or SRT and VTT subtitles — up to 20 pages per translation. In Basic — fast translation without AI, in Pro — translation with the AI model.

Yes: save a document in another format, combine images into a PDF, split or merge PDFs, turn pages into JPG or PNG images — all on the phone.

Yes, in Pro: "Recognize text" (OCR) turns a scan or photo into TXT, DOCX or a searchable PDF — up to 50 pages at a time. There is also "Text from camera".

The image editor changes size, quality, rotation, crop and format (JPG, PNG, WEBP, BMP, TIFF). In "Metadata (EXIF)" you can view, edit or remove the date, camera and location.

Yes, the QR code and barcode scanner works offline and for free. Scan with the camera or choose a photo with a code; the flashlight helps in the dark.

Scan the network's QR code and tap "Connect". For a code with a number there is "Call", for a link — "Open".

Yes: in "Create" — a QR code with text, a link, Wi-Fi, a contact, a phone number, e-mail or SMS, or a barcode. Save the code as PNG or show it full screen.

Yes, scanned and created codes are kept in "History" on the phone, with search. In Basic — for 7 days, in Pro — without limits.

Basic — free forever:

• Text and voice translation in all languages, fully offline
• Listening to translations
• QR codes and barcodes: scanning and creating

For the first month from the first launch, all Pro features are free, no card needed. Pro features are marked with a PRO badge in the app.

• Pro for a month — one payment, no auto-renewal — for a trip
• Pro for a year — subscription, cancel anytime in Google Play
• Pro forever — one payment, including future Pro features

Prices are shown in Google Play and in the app on the "License" screen. Pro works without internet once purchased. On a new phone with the same Google account, tap "Restore purchases".

Android 11 or newer, installed from Google Play. The translator without AI, the converter and the scanner work on any such phone.

• Less than 4 GB — fast translation without AI (text, voice, documents), QR codes and barcodes
• 4 GB or more — all of the above + the light AI model
• 6 GB or more — all of the above + the accurate AI model (best with 10 GB or more)

The app checks the phone's memory itself and offers only the models that fit.

The light AI model is about 2.6 GB, the accurate one about 3.7 GB; a model is downloaded once and only if you choose it. Languages are downloaded separately — only the ones you choose.

• No ✨ button or AI unavailable — the phone doesn't have enough memory for the model; fast translation works.
• "Not enough storage" — free up space on the phone.
• Translation is not read aloud — in "Offline languages" tap "Install voice".
• Another problem — "About" → "Report a problem".
