## 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

## Trans Frame

Trans Frame solves a very specific and very common annoyance: text that lives inside images, graphics, video frames or canvas-rendered UI, where ordinary copy-and-paste simply does not work. You activate the extension on a page, drag a frame around whatever you want to read, and Trans Frame captures that region as an image, applies AI text detection to recognise the characters, and returns a translation you can read immediately. Because the source is a screenshot rather than the page's DOM, the approach works equally well on infographics, scanned documents, photographed signs, embedded video subtitles and content bundled into third-party widgets.

The extension is lightweight in concept and free to install. It ships with no subscription, no account requirement and no data-collection disclosure beyond the developer's statement that user data is not sold or shared for unrelated purposes. The store listing shows a small but genuine user base and an update that keeps the extension compatible with current Chrome builds. It appeals most to language learners, travellers and cross-border knowledge workers who regularly hit the wall of unselectable foreign text.

If you already use a page-level translator, Trans Frame is complementary rather than a replacement: it covers the visual layer those tools usually miss. The main trade-off is that AI recognition on screenshots is only as good as the image quality it receives, so small, low-contrast or heavily stylised text can produce imperfect results. For clean, well-lit content it is a fast and frictionless way to break through a language barrier without leaving the page.

**Pricing & Plans:** Free to install and use. The Chrome Web Store listing shows no paid plans, subscriptions or in-app purchases; the developer states that collected data is not sold or shared for unrelated purposes.

- **Screenshot-based text capture:** Draw a frame over any area of a web page and capture it as an image, so text inside images, videos and canvas elements becomes readable.
- **AI text recognition:** AI text detection reads the characters in your captured region and turns the image into editable, translatable text.
- **Instant translation:** The recognised text is translated straight away so you can understand foreign-language content without leaving the page.
- **Works where copy-paste fails:** Because capture is visual rather than DOM-based, the extension handles infographics, scanned documents, subtitles and rendered widgets.
- **Free and account-free:** Install from the Chrome Web Store and start using it immediately with no sign-up, subscription or paywall.

**Strengths:** Free with no account or subscription required; Solves the problem of unselectable text inside images and video; Simple capture-a-frame interaction that requires no learning curve; Works alongside ordinary page-level translators rather than competing with them

**Limitations:** Recognition accuracy drops on small, blurry or stylised text; No offline mode, so results depend on an active connection; Full-page translation is not its purpose, which may surprise some users
