Instead of setting aside study time, you install the extension and keep reading the sites you already visit. Any English word on a page can be highlighted to see a translation, and one click saves it to your personal wordlist along with example context. The extension then does the passive work. Saved words are highlighted on other websites you browse, creating repeated exposure without extra effort, and Elia also recommends new words suited to your level, with the company claiming learners can pick up around 300 words a month. Daily goals, progress tracking, a 50+ language translation range and PDF integration round out the experience. Elia is a paid product with a 7-day free trial on all plans. Subscriptions run €5.99 per month or €49 per year, with a €249 one-time lifetime option. It is GDPR-compliant, works in Chrome, and requires an account so your wordlist syncs across sessions. **Pricing & Plans:** 7-day free trial on every plan; €5.99/month, €49/year, or €249 one-time lifetime. All plans include unlimited lookups, recommendations, practice, translations into 50+ languages and daily goal tracking. - **One-click word translation:** Highlight any English word on any webpage and see its translation instantly, with support for 50+ target languages. - **Personal wordlist:** Save words and phrases you look up so they build into a searchable, growing personal vocabulary library. - **Highlights on other sites:** Elia resurfaces your saved words on the websites you visit later, turning casual browsing into built-in review. - **Level-aware word recommendations:** Get new words suggested at your current level so you are always reading slightly above your comfort zone. - **Daily goals and progress:** Set a daily target and track how many words and phrases you have mastered over time. **Strengths:** Vocab review happens automatically inside normal browsing, so there is no separate study session; Translations, saved words and level-matched recommendations all sit in one small extension; Lifetime plan is a genuinely different option from the usual monthly subscription treadmill; Company states GDPR compliance and gives a 7-day free trial on all tiers **Limitations:** Chrome-only at the time of writing, so Safari, Firefox and mobile users miss out; Requires an account before you can save anything, which adds friction to a first try; Effectiveness still depends on you actually reading English-language pages regularly [Profile (Markdown)](https://openaitools.app/tool/elia.md) ## InterSub InterSub takes the idea of immersion learning and puts it inside the shows you already watch. It is a browser extension for Chrome, Edge, and Firefox that layers two subtitle tracks over the video player: one in the language you are learning and one in your native language. Instead of switching between a video and a dictionary tab, the explanation appears exactly where the problem is. Hovering over any subtitle word pauses the video and opens a pop-up with an AI-generated definition and a context translation of the words around it. Every lookup is saved to a personal Wordbook together with the sentence it came from, so vocabulary review is built from real scenes rather than generic word lists. The extension also includes an AI Language Buddy tutor that can explain meaning, grammar, and cultural references, and AI subtitle translation for episodes that have no subtitles in your language. InterSub works across Netflix, YouTube, Prime Video, HBO Max, Crunchyroll, TED, Coursera, Udemy, LinkedIn Learning, Bilibili.tv, and several other platforms, with dozens of language pairs. It also handles study mechanics: a pause-only subtitle mode trains listening, shadowing mode stops after each line so you can repeat it aloud, and a Telegram bot runs spaced-repetition drills on your saved words with Anki sync as an alternative. Dual subtitles themselves are free, with lookups limited each month on the free plan. **Pricing & Plans:** Free to start with dual subtitles included. The free plan allows a limited number of word lookups each month; Pay-as-you-go and Premium plans add more lookups and unlock AI subtitle translation. Exact prices are listed on the site's plans page. - **Dual subtitles in your two languages:** Watch with the subtitle of the language you are learning and your native language stacked, one line above the other, directly inside the video player. - **Hover pop-up dictionary:** Hover any subtitle word and the video pauses while a pop-up shows an AI-generated definition plus a translation of the surrounding context. - **Self-filling vocabulary builder:** Every word you look up lands in your Wordbook with its original context, so you build a personal list from scenes you actually watched. - **AI subtitle translation:** If an episode has no subtitles in your language, InterSub translates them on the fly with AI and shows the translation as the second line. - **AI Language Buddy tutor:** Ask a ChatGPT-powered tutor what a word means in this scene, why the grammar works that way, or what a cultural reference is about. **Strengths:** Dual subtitles and hover lookups happen inside the player, so you never leave the episode; Vocabulary is captured automatically with the sentence it came from; Supports dozens of language pairs across streaming, learning, and anime platforms; Extra study tools like pause-only subtitles, shadowing mode, a Telegram bot, and Anki sync **Limitations:** Desktop browser extension only, with no full mobile app; Word lookups are capped each month on the free plan; Requires an internet connection for translations and subtitle synchronization [Profile (Markdown)](https://openaitools.app/tool/intersub.md) ## Frequently Asked Questions ### How do Elia and InterSub compare in monthly traffic?
