## inContext

inContext positions itself as a novel AI dictionary for language learners. Traditional dictionaries give you every possible meaning of a word; inContext tries to give you the one you actually need. When you highlight a word, it inspects the sentence around it, decides which sense applies, and writes a short explanation in vocabulary matched to your level so you are not sent chasing more unknown words inside the definition.

The extension lives in Chrome and works on whatever you are already reading, from news articles to documentation. A side panel keeps a running record of the words you looked up and the context in which you met them, turning incidental reading into a lightweight review list. Because it runs in the browser and processes text with AI, it needs a connection while you use it.

The product is published by incontextlearning.com and it is a small, young extension — roughly 63 users at the time of review, with a perfect but very limited rating. It is a focused reading companion rather than a full course, so it works best alongside other study material rather than replacing it.

**Pricing & Plans:** Listed as free in the Chrome Web Store, with optional in-app purchases available. No public tier breakdown is shown on the store listing.

- **Highlight-any-word lookups:** Highlight any word on any page and inContext immediately shows its meaning without leaving the article, PDF or website you are reading.
- **Context-aware definitions:** The extension reads the surrounding sentence to choose the sense of the word that actually fits, rather than returning a generic entry.
- **Level-adjusted wording:** Explanations are pitched at your language level, so the definition itself uses words you already understand.
- **Side-panel word history:** Every looked-up word, plus the sentence you found it in, is stored in the side panel for later revision.
- **Works across the web:** Runs entirely in Chrome, so it works on news sites, blogs, documentation and other web text you already read.

**Strengths:** Fits into pages you already read instead of forcing a separate study session; Context-first definitions reduce the guesswork of picking between senses; Explanations are written at your level, avoiding nested unknown words; Lookup history with context makes review easy

**Limitations:** Only about 63 users, so the community is small; Single-language focus per session; no built-in grammar drills or courses; Requires an internet connection and AI processing for every lookup

## 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
