## 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

## Scouter - Language Learning

Scouter - Language Learning is a browser extension built around a simple idea: language acquisition works best when you meet words in real context rather than in isolated vocabulary drills. Instead of copying sentences into a separate study app, you keep reading, watching and browsing, and Scouter breaks down what is in front of you, explains how words behave in that specific sentence, and offers images or dictionary lookups that make the meaning stick.

The extension summarizes webpage content, works with YouTube videos, and accepts custom prompts so you can shape how explanations are produced. Vocabulary you decide to keep goes into Anki in one step, complete with pronunciation, phrase and example sentence, so the bridge between passive exposure and spaced-repetition review stays short. A multilingual interface and one-on-one customer support via its Discord community round out the experience.

Scouter supports a range of model backends, including GPT-4, Claude and locally run Ollama models, alongside free online dictionaries, which lets privacy-conscious users or anyone with an existing API key keep their setup affordable. It is distributed through the Chrome Web Store as a free extension with optional paid capability, and it sits in the language-learning category alongside tools like Lingoku and LiveLang.

**Pricing & Plans:** Listed as freemium on the Chrome Web Store: the extension can be installed at no cost, and paid options unlock expanded usage. Check the extension listing for current tiers.

- **Contextual word explanations:** Understand how a word is used in a specific sentence from the page or video you are reading, rather than relying on a generic dictionary definition.
- **One-click Anki export:** Send words, pronunciations, phrases and full example sentences to Anki without leaving your reading flow.
- **Learn from YouTube:** Watch videos in your target language and pull vocabulary directly from the subtitles and content on screen.
- **Multi-model support:** Choose between GPT-4, Claude, local Ollama models and free online dictionaries, so you can match cost, privacy and quality to your needs.
- **Custom prompts:** Define your own instructions for how explanations and summaries are generated, tailoring the study method to your level and goals.

**Strengths:** Fits into reading and video watching instead of adding a separate study session; Direct Anki integration with pronunciation and example sentences; Choice of GPT-4, Claude, Ollama or free dictionaries; Actively maintained extension with a public update history

**Limitations:** Requires Anki for the full spaced-repetition workflow; Advanced usage depends on bringing your own model access; Available only in Chrome, so Safari and Firefox users are left out
