Lookupper is a screen translator and pop-up dictionary that works on top of any window. You no longer need to copy text or Alt+Tab to a translator. TWO MODES 1. Pop-up Dictionary. For language learners. Shows the base form, IPA, part of speech, CEFR level, a definition in the exact sense the word is used in, a translation, synonyms and audio. Lookupper can save every word together with its sentence and a screenshot of where you met it. 2. Screen Translator. For when you just need to understand what's on your screen. Press the key and the text on screen is replaced with its translation. FREE OFFLINE LLM TRANSLATOR Install the Google TranslateGemma 4B model and run it on your own CPU or GPU for fully private offline screen translation, free and without any limits. WORKS EVERYWHERE Lookupper reads the screen with on-device text recognition (OCR), so it works even where text cannot be copied: in games, videos, comics, scanned PDFs. BUILT FOR GAMES Lookupper was made for games from the start. Fullscreen games work in borderless window mode, and where a game has no such mode, Lookupper stretches its normal window over the whole screen. Lookupper can freeze the game while you read the translation. The hotkey can sit on a mouse button or a gamepad button. 30 RECOGNITION LANGUAGES English, Spanish, French, German, Italian, Portuguese, Russian, Japanese, Chinese (Simplified and Traditional), Korean, Arabic, Turkish, Dutch, Swedish, Polish, Greek, Danish, Norwegian, Finnish, Czech, Romanian, Hungarian, Bulgarian, Slovak, Croatian, Serbian (Cyrillic and Latin), Slovenian, Bosnian, Indonesian and Latin. Lookupper works perfectly with Japanese, Chinese and Korean text: it automatically detects CJK words, so you don't need to guess where a word starts and ends. DICTIONARIES AND TRANSLATION 55 free offline dictionaries available to install from the catalog: Wiktionary for a dozen languages, JMdict and KANJIDIC for Japanese, CC-CEDICT for Chinese, WordNet, GCIDE and Webster's for English, Ding for German, and more. You can also import your own dictionaries in Yomitan, StarDict, MDict (.mdx), ABBYY Lingvo (.dsl) and Aard (.slob) formats. Two cloud AI dictionaries are included, and both give the exact meaning of a word in the given context. Looktionary explains the word in the sense it is used in. Context Translator translates the whole phrase taking the game or app into account. SAVED WORDS AND ANKI The Words tab keeps every word you've checked, together with a screenshot and the app it came from. Search and filter by any field. Export a word list or a Quizlet set, or (with Pro) build an Anki deck with audio and screenshots, or sync straight into Anki through AnkiConnect. FREE AND PRO Free: offline dictionaries and the offline translator Google TranslateGemma 4B, 50 cloud AI definitions and 50 cloud screen translations per day, up to 1,000 saved words, word list and Quizlet export. Lookupper Pro: cloud AI without limits, unlimited saved words, Anki export and Anki sync. PRIVACY Lookupper does not record the screen and collects no personal data. It takes a screenshot only at the moment you press the hotkey and never sends it anywhere. When idle it uses 0% CPU, so it can stay in the tray all day.
