Image from store Translator, Dictionary, AI - Definer

Description from store Double-click a word or highlight text while holding the "Ctrl" key (or another hotkey you set) to bring up a pop-up bubble with translations, definitions, images, search engine results, and more. You can quickly switch between data sources and languages, and look up words on any webpage, including PDFs. This browser dictionary app covers a wide range of use-cases, from language learning, sentence mining, and vocabulary building to academic research and casual browsing. ⭐ Key Features - Multiple built-in data sources with the option to add custom sources. - Results in multiple languages, allowing you to switch between them on the fly. - Pronunciation recordings and IPA transcriptions, with the "autoplay" feature for audio. - Shortcuts and hotkeys for different pop-up activation triggers. - Settings sync and backup with support for multiple settings profiles. - Blacklist and whitelist to control what websites and pages the pop-up bubble can appear on. - PDF support through an integrated PDF Reader. - Resizable on-page pop-up bubble. - Alternative lookup method by typing the query instead of selecting it on a page. - Dark mode support. - Four built-in themes with the option to create custom themes using the Theme Editor. - Four built-in theme schedules with the option to create custom timelines using the Theme Schedule Editor. 🌐 Sources There are several built-in data sources available, and you can also add your own sources using the "Custom Source" feature. To do this, simply enter a website URL in the settings to include it as a source. You can also apply CSS (styling language) if you want to customize how it appears in the pop-up bubble. Check out the complete list of sources in Definer Wiki at https://lumetrium.com/definer/wiki 🔠 Languages Results are fetched in multiple languages at the same time. You can set your preferred languages in the settings and rank them by priority. If there's no information in your top-choice language, results in the next preferred language will be shown automatically. You can also manually switch between results in different languages directly from the pop-up bubble. Choose from any of the 487 languages listed in the ISO 639-2 Language Code List. However, keep in mind that not all sources support every language, so the availability of results may vary depending on the language selected. 📄 PDF Support Definer comes with a built-in PDF Reader that lets you use the pop-up bubble feature on PDFs. To open the PDF Reader: click on Definer’s icon → 3 vertical dots → “PDF Reader”. Screenshots and details: https://www.reddit.com/r/lumetrium_definer/s/Hgy5ApbVoq 🎨 Appearance You can completely personalize the appearance of the extension. Change the colors, fonts, corner roundness, and even add your own CSS if you're really into customization. This is made possible by Definer's integrated Theme Editor, which allows you to design unique and attractive themes in minutes. It's also possible to configure themes to change automatically depending on the time of day by placing them on a timeline in the Theme Schedule Editor. 💬 Bubble A bubble is a small pop-up window that appears over selected text on a webpage when it's needed. You can: - Adjust the bubble's size. - Set up hotkeys to trigger the bubble. - Create rules for when the bubble should appear on certain websites or webpages. ⌨️ Hotkeys and Triggers Configure triggers and assign additional hotkeys so that the bubble only appears when you press specific keys on the keyboard while selecting text. These triggers can be tailored for special situations, such as when you're typing in a form or editing a document. There are four triggers available: - Mouse Selection: By default, hold the "Ctrl" key while selecting text with your mouse to make the bubble appear. - Double-click a Word: By default, the bubble will appear when you double-click on a word without needing any hotkeys. - Keyboard Shortcut: The default hotkey is "Alt + G", meaning you need to press these two keys at the same time after highlighting a text fragment. - Context Menu Action: After selecting a word, right-click and choose "Define [selected text]" from the context menu. This action does not support hotkeys. 🌓 Blacklist & Whitelist Definer can manage bubble activation in two modes: 1. Enabled on all pages, except those blacklisted (default setting) 2. Disabled on all pages, except those whitelisted You can create URL rules that determine if the bubble should be active on the page you’re viewing. To do this, click on Definer's icon in your browser toolbar, select "Configure," and toggle the switch for either "This website" or "This page." This creates a simple rule. However, you can also manually create more flexible rules in the settings to match URLs based on the following conditions: - Matches domain - Matches URL - URL contains - URL starts with - URL ends with - Matches pattern - Matches regular expression Definer's icon will turn gray when the bubble is disabled on the active page. ⚙️ Setting sync With so many customization options, you’ll appreciate the convenience of backing up and synchronizing your settings automatically. Definer makes it easy to keep everything in order across all your devices. - Cloud Storage: Store your extension settings in the cloud so you never have to worry about losing them. - Sync Across Devices: Whether you're on your laptop at home or your desktop at work, keep your settings consistent across all your computers and browsers. - Create Multiple Profiles: Set up profiles with different settings for various tasks or environments. - Switch Profiles: Quickly change profiles whenever you need to adjust your settings for different situations. 💡 Use Cases 1. Language Learning: Instantly translate and understand new words while reading news articles online or books in PDF. View multilingual dictionary entries with images and pronunciation recordings to improve comprehension and grow vocabulary. 2. Research: Conduct web searches without leaving the current page. This is particularly useful for students and researchers working with multiple academic sources or needing quick access to definitions and context. 3. Writing and Editing: Look up synonyms and definitions to improve the quality and accuracy of your writing. 4. Casual Browsing: Quickly understand unfamiliar terms or concepts encountered during everyday browsing without having to open new tabs or perform separate searches. 5. Travel and Communication: When planning travel or communicating in different languages, quickly translate text on websites or documents to communicate more effectively. 6. Content Creation: Gather context and definitions for terms used in blogs, news, or other media by accessing concise and relevant information quickly. 7. Accessibility: Individuals with reading difficulties or visual impairments can use the pronunciation feature to hear the selected text read aloud, aiding in comprehension and accessibility. 8. Technical Fields: Professionals in technical or specialized fields can swiftly look up complex terms or jargon related to their work. ❓ FAQ WHY DOESN'T IT WORK ON SOME PAGES? The bubble will not work in tabs that were open prior to installation. It's recommended to restart your browser after installing this extension. WHY IS A SOURCE GRAYED OUT? If results for a particular source aren't found, that source will be grayed out and skipped to the next one. CAN IT WORK ON PAYWALLED PAGES? Yes, it works on any webpage, including those behind paywalls. DOES IT WORK ON EPUB (E-BOOK) FILES? Yes, it can handle .epub files if you use an online reader like https://reader.ttsu.app DOES IT WORK IN GOOGLE DOCS? No. Google Docs renders its contents in a way that restricts extensions from accessing the text directly. As a workaround, download the document by going to "File" -> "Download" -> "PDF document". After that, open the file with Definer's built-in PDF Reader. 🔑 Permissions and Privacy For detailed explanations of each permission that Definer uses, check out the Privacy Policy on the Lumetrium website: https://lumetrium.com/legal?service=definer&document=privacy-policy ⚠️ Troubleshooting If something isn't working properly, here's what you can try: - Restart your browser. This often fixes minor glitches. - Temporarily disable other extensions. They can sometimes conflict with each other. - Reinstall the extension. If all else fails, a fresh install might do the trick.

(2025-04-06) V B: 14/10/2023 - 5 stars Hi, i want to get definitions and images together, how to do it? 07/04/2025 - 1 star Please add the functionality to get definitions and images together without clicking on the image tab. This will be much better for association-based learning.
(2024-03-28) Nima Ghasemi: for Custom : go to Sources go to Custom click on Configurable source copy this: https://www.merriam-webster.com/dictionary/{str} paste it in the URL field
(2023-11-15) Melody Mastache: Doesn't work on anything outside of the settings page. Have tried fiddling with the settings, but that didn't help.
(2023-10-22) Dmitry Trofim: Крутой переводчик, рад что наткнулся)
(2023-10-19) Ed Giles: It's a great extension. I would love to be able to add multiple custom sources, but otherwise it's incredibly useful.
(2023-10-11) Rafael Carvalho: muito bom e completo
(2023-09-21) H: Do you perhaps have android version as well? I really like this extension! If you have change to make android version, it would be perfect if it has bobbles (similar to Facebook Messanger's chat head) function as well (to find words easily anytime)!
(2023-09-20) Ayush Sharma: damn
(2023-09-19) Samuele gg: Sebbene la descrizione (parzialmente) e il titolo dell'estensione sono in italiano, la lingua italiana nelle opzioni della scelta della lingua non è disponibile. Deludente. Although the description (partially) and the title of the extension are in Italian, the Italian language in the language selection options is not available. Disappointing.
(2023-09-19) gem bank: perfect and flawless
(2023-09-15) *: Confusing settings, the wordings and the terms. Unfriendly triggers. Hotkeys don't work. (Even a small thing like Ctrl+Shift+1 shown as Ctrl+Shift+! makes just a bad impression.) Browser level pop-up isn't prompted with highlighted text, I have to type it manually each time. Base language cannot be opted out from automatic translation. Heavy bloated but the essential features aren't there.
(2023-09-14) Raihan Sifat: Excellent Extention.
(2023-09-11) Jason: Nice app, English is my second language so it really saves me a lot of time of definition looking when I am reading long (900 to 2000 pages at this point of the game) textbooks and this product, this ingenuity is one of the few ones that are actually providing this kind of service with clean designs and nice user interface. BUT, but, somehow the shortcuts for opening this page just wont work. Even when I switch the shortcuts to other keyboard inputs. The shortcuts only work when I read a pdf in the integrated pdf reader, and it won't work in other occasions, such as texts/doubleclicks/keyboard inputs in Chrome. I really hope you can fix this because the usage will be much much more efficient:)
(2023-09-05) a b: May you find eternal peace and love. From first glance I thought your extension was created by a company, not an individual. It was only when I found your reddit post that I gave your extension a shot. I'm so glad I did. It solved literally all my problems (of today.) If I wasn't a student, I'd donate, and I really implore others to do the same.
(2023-08-28) AmirHuseyn Erfanifar: Oh my GOD, you made THE DICTIONARY. I love your extension. I love the fact that you put lots of options for customization. I love that you guys knew what people needed and tend to build it. I cannot emphasize on me gratefulness. Writing a review was the least I could do. I'm going to introduce your extension in my blog soon. You absolutely ROCK.
(2023-08-22) Jonathan Armani: Absolutely Perfect! Took forever to find a descent, double/right click - text to speech. This extension went far beyond what I expected. No more opening separate tabs. Double click, for speech, definition, web search and more, all within the pop-up bubble. How is this not advertised more? Best extension of it's kind by far. Thank you to the developers.
(2023-08-21) Othman Muslim: way better than the google dictionary extension
(2023-08-16) Alfeddy naoufal: Fantastic extension, i just wished it could be an app for windows because i saw myself needing to use it in a lot of apps rather than the browser.
(2023-08-16) Dan Ou (Dummz): Nice, simple to use, awesome. Wished more people knew about this
(2023-08-15) Pedro Paulo: This extension is so good that Google shoud incorporate it to Chrome
(2023-08-14) Maulvi Arbal: great extension would love to have options to disable it on certain site
(2023-08-01) Đăng Nguyễn Ngọc: Great
(2023-07-27) Jaime C: Buenísimo! Pero por favor añadan Wiktionary, Wiktionnaire y Cambridge :(
(2023-07-19) Danielle Brown: This is going to take my study sessions to the next level! Love it!
(2023-07-10) Mikola Chamlay: Спасибо большое, это то что нужно! Очень приятное приложение, все сделано красиво и гармонично да еще и функционально! разработчики молодцы! Добавьте пожалуйста по возможности словари Oxford, Сambridge и Collins
(2023-06-27) Johaan T: This is unreal
(2023-06-03) KristijanRoss: This is the ultimate popup definer! Waaaay better than Grammarly. With so many configuration options, it's a must have browser extension.
(2023-05-19) Denver Naicker: simple, easy to use
(2023-04-27) Ted Beckam: Please allow us to make more custom sources and delete default sources.
(2023-04-05) Вадим Погрибельный: Отличное расширение, единственный недостаток, хотелось бы чтобы pdf открывались автоматически через него. Тогда будет все 5 звезд
(2023-04-04) ChaneyChane: The design is very beautiful and easy to use! The extension is so helpful. I was finding some pop up translation similar to how Rikaikun works but with languages other than Japanese and this is definitely it! Thank you.
(2023-03-28) Тимур: Супер расширение, очень удобное и функциональное. Хотелось бы еще добавления альтернативных источников перевода, например, Яндекс переводчик и DeepL.
(2023-03-15) Alex Stupin: Очень редко пишу отзывы, возможно это мой первый отзыв для расширения хрома. Раньше часто использовал расширения для перевода отдельных слов/предложений по выделению, и, самое главное, чтобы перевод отображался во всплывающем окошке. Теперь потребовалось аналогично производить поиск по словарю, дабы узнать определение умных слов. Долго искал, и наткнулся на данный сабж. Это просто отличное расширение, которое полностью соответствует моим текущим потребностям: - Отображение результата во всплывающем окошке - Перевод - Поиск по словарю - Поиск по википедии - Поиск картинок - Гибкие настройки, как отображения, так и поведения 5 из 5! Рекомендую.
(2023-03-11) saunaperse: Best extension
(2023-02-23) Mrinal Kr Gupta: Never seen an extension which helps you in all ways. Inbuilt researching with translation and defining and even images for reference, just WoW it is. I would just like to suggest an additional source of JSTOR.com. When you have Wikipedia, google, DuckDuckGo, Bing images, why not search for some articles or docs for further help, obviously to one who's interested.
(2023-01-14) qq qq: Спасибо. Как прикрутить chatGPT?
(2022-12-30) A M: Functions that can enhance user experience: (1) Function to save searched words. (2) Manual search bar on within popup to search word other than selected
(2022-11-30) Ameya Deb: Amazing extension overall Just ran into a bug which I wanted to bring up. The extension is breaking some google spreadsheet websites, causing the scrollbar and whole page to freeze up. Examples include sites like <https://releases.moe/> and <https://index.fansubcar.tel/>. Edit: fixed now!
(2022-11-26) Erzhan Ernat uulu: pdf reader is amaizing guys,i love it thank you very much
(2022-11-23) 2000 Way: 제가 경험해본 팝업 사전중에 최고의 팝업 영어 사전입니다. 영한 사전 어휘가 너무 적은게 단점이네요.
(2022-11-10) Jamie Wu: Can you please add DeepL as a source?
(2022-11-06) Machete Movies: Me ha sido de mucho utilidad, pero sería grandioso que pudiera añadir más Recursos personalizados, ya que solo permite añadir uno.
(2022-10-31) Николай Козлов: Весьма симпатично. Пользовательскую ссылку всячески поддерживаю, более того, позволил бы неограниченный список таких ссылок. И, пожалуйста, сделайте регулировку размера шрифта.
(2022-10-20) Syed Abdullah Nasir: Dictionary, translator. wilkipedia and google search engine all in one extension. Amazing, loved it. Also there should an app like this for smartphone use.
(2022-10-18) Дмитрий Минаев: Отличное приложение! Можно добавить в настройки назначение нескольких клавиш при переводе предложений. Great app! You can add in the settings assignment of shortcuts when translating sentences.
(2022-10-15) Martin VanBuren: I love being able to rate an extension 5 stars. This one definitely deserves it. Well done, dev!
(2022-10-05) Poojan Goyani: Amazing ..... I used it mostly for pdf reading.... keep up the good work and the best thing is that the extension is completely free !!!
(2022-09-23) Giuseppe Circelli: Best translate extension for browser
(2022-09-14) Joon Song: Is it possible to adjust the text length limit? I use it as a popup translator, the string is truncated.
(2022-09-06) K S: Hi, It's a very nice extension, thank you! Can you please add a Keyboard shortcut option to Activate the Bubble? Because sometimes I just want to search some word which suddenly come out from my brain.
