Type or paste your text, pick the languages you care about, and the extension returns all of them in a single view. It runs on the Google Translate API, so the underlying engine is one you likely already trust, and it covers 91 languages with automatic source-language detection. The extension is deliberately small (about 150 KiB) and installs in seconds. It follows Chrome's recommended extension practices, runs on the current Manifest V3 platform, and supports right-to-left scripts plus phonetic readings where the target language provides them. Everyday interactions are handled with built-in copy and paste buttons, so moving a result into a document, chat, or flashcard app takes one click. It has held a 4.8-star rating on the Chrome Web Store with roughly a thousand active users and is updated periodically — version 5.0.4 arrived in April 2025. It is important to be clear about what this is: Synchrolator is an independent third-party extension offered by an individual developer under the name Peym4n. It is not an official Google product, even though it calls the Google Translate API for translations. Because the extension is free and does not collect or sell user data according to its store disclosure, it is a low-risk way to add quick multi-language output to your browser — but it is a convenience tool rather than a full translation management or localization platform. **Pricing & Plans:** Free. Synchrolator is distributed at no cost through the Chrome Web Store, with no subscription, account, or in-app purchase required. - **Up to 10 languages per query:** Send the same text to as many as ten target languages at once and read every result in one place. - **91 languages supported:** Backed by the Google Translate API, the extension spans 91 languages, including widely spoken and less common ones. - **Automatic source detection:** Leave the source language unset and Synchrolator identifies the language of your input before translating. - **Right-to-left and phonetic support:** Rendering is handled properly for RTL scripts, and phonetics are shown when the target language provides them. - **One-click copy and paste:** Built-in buttons move text in and results out without leaving the popup. - **Small, current, low-permission build:** Roughly 150 KiB on the latest Manifest V3 platform, with a store disclosure stating no data collection or selling. **Strengths:** Completely free with no account or signup; Returns up to ten languages from a single query; Covers 91 languages with auto source detection; Small download (~150 KiB) and fast to install **Limitations:** Requires Chrome (or a Chromium-based browser) and a Google account for the Web Store; Only works inside the browser extension popup — no mobile app or desktop client; Ten-language cap per query; No glossary, translation memory, or team/localization workflow features [Profile (Markdown)](https://openaitools.app/tool/synchrolator.md) ## Trancy Trancy is an all-in-one language learning assistant built around the idea that the fastest way to learn is to turn the content you already want to watch into study material. Its browser extension adds AI-generated bilingual subtitles to platforms including YouTube, Netflix, HBO Max, Disney+, TED, Udemy, edX, and Coursera, showing the original and translated text together. Two display modes — theater and reading — let you keep the video visible for listening practice or shrink it to the side and focus on the subtitle text for intensive comprehension. The learning layer goes well beyond subtitles. Selecting a word or sentence triggers AI-powered lookups with definitions, grammar analysis, and part-of-speech tagging, while intelligent sentence segmentation uses NLP to reorganize messy subtitle fragments into coherent sentences. You can bookmark words and example sentences into decks, highlight unknown words so you absorb them passively while browsing, and queue videos to watch later. A web-based learning center makes all of it accessible from anywhere for review. Trancy also works away from video. On ordinary web pages and PDFs it offers selection translation, hover-based paragraph translation, and full-text immersive translation that shows the original and translated text together, with support for engines like Google, DeepL, and OpenAI. On the speaking side there are lifelike text-to-speech voices, speech recognition for pronunciation feedback, speed playback, and full subtitle font customization. It is available as a browser extension and a companion mobile app, and the company continues to ship new tools such as the AI Subtitles and AITalk features. **Pricing & Plans:** Trancy uses a freemium model with a free tier that covers core subtitle and translation features with limited premium usage, plus free trials and paid subscription plans that unlock higher limits and advanced AI features. Details are listed on the pricing page. - **AI bilingual subtitles:** Watch videos on YouTube, Netflix, HBO Max, TED, and course platforms with side-by-side bilingual subtitles in theater or reading mode. - **AI word and grammar analysis:** Get instant definitions, grammar breakdowns, and part-of-speech tagging for selected words and sentences using AI and NLP. - **Immersive web and PDF translation:** Translate selected text, paragraphs, or entire pages in place, with bilingual comparison and a choice of translation engines. - **Vocabulary decks and sentence library:** Save words and real-life sentences to decks, highlight unknown words as you browse, and review them in the web learning center. - **Listening and speaking practice:** Practice pronunciation with lifelike text to speech, speech recognition, speed playback, and subtitle font controls. **Strengths:** Turns real video content on major streaming platforms into study material; Bilingual subtitles with both theater and reading modes; AI grammar and word analysis tied directly to what you watch; Immersive translation for web pages and PDFs **Limitations:** Best experience depends on keeping the browser extension or app installed; Speech and advanced AI features rely on third-party engines that may have their own limits; Free tier caps usage of premium AI features such as some translations and studies [Profile (Markdown)](https://openaitools.app/tool/trancy.md) ## Frequently Asked Questions ### How do Synchrolator and Trancy compare in monthly traffic?
