- (2025-08-08) 7Jazzy Jazzy: Wish I found it earlier! It's awesome
- (2025-07-31) Arsenii: This exstension has improved my web experience a lot. But i just hope there wouldn't be annoying payment requirements... don't ruin this excellent thing!
- (2025-07-29) Олег Барамиков: When using the Arc browser with a specific extension enabled, I’m unable to sign in to platform.openai.com via Google. I get the following message: “We ran into an issue while authenticating you. If this issue persists, please contact us through our help center at https://help.openai.com.” Disabling the extension resolves the issue. Might be worth looking into compatibility.
- (2025-07-27) Adrian A: It's working perfectly. The only issue I have is that when I open the Google search window, Google's AI Overview option appears for a split-second, before disappearing from the I-frame. This happens to me in Brave browser. Please fix this, because this extension is otherwise very useful.
- (2025-07-24) ghfbfb ghfnvvh: scam
- (2025-07-04) Julian Harris: alot more useful than google dictionary
- (2025-07-04) kei wilson: Awesome extension! It's comprehensive and significantly improves my reading experience and access to non-native language materials. It would be even better with vocabulary.com and etymonline as sources.
- (2025-07-03) Chensong Li: Such a fantastic extension! Very smooth, very concise and clean, and exactly functioning as a dictionary and translator. I wish I can pay for it! But it only accept cryptocurrency, which I don't have. That is the only downside!
- (2025-06-29) p fuhad: Awesome app. Can you provide option for 11labs tts api with our .own key
- (2025-06-29) Farhad Barahimi: This extension is fantastic! It's comprehensive and exactly what I wanted for daily reading. Thank you!
- (2025-06-27) Dang Khanh Dinh: It's a neat extension. I'm used to using Look Up feature on Mac, which isn't a built in feature on Windows. This extension did exactly that.
- (2025-06-24) Ȼaptain Jøhn “Søap” MacTavish: Needs Wikitionary as a source
- (2025-06-22) YESEUL JEONG: This is a truly wonderful extension meeting most of users' requirement.. I really appreciate that!:) If I may, I would like to make one small feature suggestion. For language learner, it's essential to selectively review the newly learned words. Would you kindly consider adding the history download features like google dictionary extension?
- (2025-06-19) Showrav Acharjee: a must have extension for people like to read a lot online, and my god the level of customization is insane! was looking for this sort of extension for a long time. many thanks to the developer.
- (2025-06-18) Tran Hung: Really wonderful extension, a lot of choices, a lot of freedom for the user, it's not simply an dictionary, but a tool for searching in click. Learn how to use it and it will help you a lot. And another best thing, if you have any idea to improve the extension, you could contact the developer, he/she eager to hear you and support you very quick
- (2025-06-15) VU HOAN PHAM VAN: Your app is truly amazing — thank you so much for creating such a helpful tool! I use it regularly and really appreciate the thoughtful design and smooth experience. I have one small feature suggestion that I think could make it even better: would it be possible to add a highlighting feature, similar to what the Chrome extension Web Highlights offers? (https://chromewebstore.google.com/detail/web-highlights-pdf-web-hi/hldjnlbobkdkghfidgoecgmklcemanhm?hl=en). I often highlight important content while reading online, and it’s incredibly convenient when those highlights are saved and reappear whenever I revisit the page. It would be wonderful if your app could support something like that — ideally for both webpages and PDFs (including local files and URLs). Thanks again for all your work — I’m truly grateful for what you’ve built, and I’m excited to see how the app continues to grow!
- (2025-06-08) Olesia Kniazeva: Your app is just perfect! I tried to find one which can make translations with ai, as well as give me definitions, but it giving far more then i expected, it was such a pleasure to see youglish in there! And all those configurable options! And it's design is so nice. It would be even more great if you would add tatoeba site by default, with configurable option on amount of words for an example sentese to include based on selected word. (https://tatoeba.org/en) and it would be nice to have forvo as well for audio from natives (https://forvo.com/) But actually, it's already such a great helper extension, can't even think about better option! Thank you for this aid for language learning
- (2025-06-01) ansh: just wow
- (2025-05-24) Zahara Kendagor: An amazing dictionary tool. Quite literally the best I've ever used. It doesn't just look up words, it can be used to look up entire phrases and slang terms. And setting up hotkeys makes this tool super easy and convenient to use. I don't know what I ever did without this!
- (2025-05-23) Emre Yildizci: I really like the extension and have been using it for almost a year I think. But recently google search option has been giving me the "I'm not a robot" checkbox page and it never goes away even when I check the checkbox
- (2025-05-18) Khelfaoui 04: it's very good extension . it has fast search . you should be get it
- (2025-05-08) Cloud Studio: Can't make double tap to define feature for PDFs. yeah, I gave it permission for url files. hopping for you to look into it Otherwise, an excellent extension.
- (2025-05-03) Deepak Shah: Absolutely delighted to use this, it's well made, and is certainly better than the defaults! I like the onboarding, also, an extension where the usage and features are so well described!
- (2025-04-27) Daniel Barreto: I'm really impressed with how well this extension works.
- (2025-04-25) Austin Pang (4us9): This extension is a god send! I was getting really annoyed with Google's Dictionary so much so that I planned on making an extension myself, lol. After being frustrated enough from Google Dictionary extension, I came across Definer. This is what I wanted and more.
- (2025-04-18) Ian Joseph: Absolutely amazing and incredibly useful for a multitude of workflow relief. God, I love this extension! I want to reiterate the words of the other reviewers here and acknowledge the creators effort to make this app as high quality as it is. Magnificent work and this is now a solidified part of my workflow and keeps me on task effectively. Thank you for this amazing extension and I wish you even more success!
- (2025-04-17) Sam Bay: I love the Definer. Is it possible to add tooltip hover feature?
- (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.
- (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.
- (2025-03-07) Homan Wong: It's a simple, easy-to-use yet very customizable extension! I wish I could change the icons for my custom sources, whether to choose one from Material Icons, to fetch the favicon from the website, or just to let me specify the URL myself.
- (2025-03-07) cHaN E: I've been using Definer for months and so far, it's the most satisfying Chrome extension I've tried. I just wanted to thank you for creating this tool. As someone who easily loses focus, this extension has been a tremendous help in keeping me engaged while reading and looking up information I'm unfamiliar with.
- (2025-03-05) Violet_ Ember: This is SOOOO helpful, I love it the way it is. But would you be able to adjust the text size on the bubble as well? Not just the bubble.
- (2025-02-27) Nicole See: Super convenient and super easy to use! It supports various languages and it's free! Every language learner should definitely install this! It has everything that you need when you want to know more about something in foreign language. It can translate and pronounce words and even short phrases, even provides synonyms. Highly recommend for everyone!
- (2025-02-18) saman: Dear lumetrium, I would like to extend my heartfelt appreciation for your relentless efforts and hard work in developing this exceptional program. The highly practical customization options, the beautifully designed user interface, and the remarkable speed truly set it apart as unparalleled. Should the capability to integrate various artificial intelligence models, particularly Google’s Gemini, be incorporated, this program would undoubtedly elevate itself to become the most outstanding application available in the Google Store. Moreover, the absence of certain features that are available in apps such as "Vocably" and "Masterlingo" is strongly felt. These include functionalities like word highlighting based on the level of learning progress, a spaced repetition system, and other similar tools that enhance the language learning experience. The incorporation of such features could significantly improve the effectiveness and user engagement of this application. Thank you once again for your dedication and commitment to excellence. Sincerely, [sam]
- (2025-02-12) Eren Kara: Perfect. If there was a button to save words it would be even better.
- (2025-02-07) Marek Pietrak: Very useful, not invasive and customizable. Exactly how it should be. Thank you for this.
- (2025-02-01) Nicholas Ferrara: This is a jaw dropping improvement in productivity for language learning. It is amazingly customizable which means whatever source you need can be added and displayed painlessly. I used to try to stitch multiple extensions together and I still wasn't able to display as much as Definer does all by itself in a compact usable interface. No more copying and pasting stuff to your dictionary of choice!
- (2025-01-31) Zakaria Khedri: well done guys
- (2025-01-24) Eysan Yazıcı: Extremely helpful!
- (2025-01-24) Xela O.: excellent in every way. one of the absolute best extensions i've ever used - they should be proud. only suggestion would be to fine tune the wikipedia plugin to be able to recognize disambiguations and alternate names to better find the relevant wikipedia page. e.g.) if I highlight "Barack Hussein Obama", I can get his page to pop up on the Wikipedia plug-in, but if I just highlight "Obama", it doesn't take me to his page nor does it ask me if I want to select his, Michelle's etc. (Wikipedia generates a page with all of the disambiguation options when you type something vague, i don't know if you could connect and display it for selection somehow.) THANK YOU!
- (2025-01-15) Achim Braemer: Fantastic extension! I love the contextual search in mobile Chrome (just long tap any word). Never undestood why it is not available in desktop Chrome. I was looking for something like it and was happy to find this extension, which gets *very* close. (You may want to mention that in the description to help people find it). Great job! Only downside: I would like to donate, but don't have crypto currency. Please provide a Paypal account. One suggestion: Please make the popup close on Esc key. That key press is hardwired in my spine and it is always a downer when it doesn't work.
- (2025-01-15) Rocky Wang: This is very helpful with great design! It will be even better if the learning curve of adding custom sources is lower. I still couldn't add cambridge dictionary source into it: tried multiple variations and still doesn't work properly. Such as "https://dictionary.cambridge.org/dictionary/english-chinese-simplified//definer/iframe?text={str}&lang={lang}"
- (2025-01-14) Faisal H.: i started to read a book and there are some words on every page that i don't know the exact meaning now thanks to this extension i can just know the meaning of that word just by double clicking instead of searching on a next chrome tab which result in lose focus while reading a book
