## Overview

Most language apps decide what you should study. Viduu inverts that: you keep watching the videos you genuinely enjoy in your target language, and the extension supplies the scaffolding. It acts as a combined librarian and tutor, first working out how hard the current video is for you, then generating questions anchored in that specific content.

The mechanism rests on text. Viduu expects videos to carry subtitles or on-screen text it can read, because that text is what the AI classifies and questions. Anything with usable captions — a documentary, a stream, a tutorial — can be converted into study material, which makes the pool of available lessons effectively unlimited.

It is a small, independent project rather than a funded product: the listing sits at version 1.0 from January 2023 with a handful of installs and no ratings. Treat it as a lightweight experiment worth trying if the idea appeals, and set expectations accordingly.

## Pricing & Plans

Listed on the Chrome Web Store as Contact for Pricing. No tiers or figures are published on the extension page.

## Key Features & Capabilities

- **Automatic difficulty classification:** The extension reads what you are watching and estimates whether the language is above, at, or below your current comprehension level.
- **Content-aware question generation:** Questions are generated from the actual content of the video rather than from a fixed textbook, so practice matches your interests.
- **Turns video subtitles into lessons:** Any video with captions or on-screen text becomes study material, turning ordinary browsing into language practice.
- **Self-directed, hands-off setup:** Difficulty tuning and questions are handled by the extension in the background, without you assembling a syllabus by hand.
- **Works across subjects and levels:** Because the source is your own viewing habits, the same tool works across genres, topics and levels.

## Primary Use Cases

- **Practice with channels you already follow (Self-taught learner):** Pick videos you would watch anyway, let Viduu score the difficulty, and answer the generated questions as a self-check after each session.
- **Build comprehension checks from authentic video (Language teacher):** Choose a clip or lecture, have Viduu produce questions from it, and use those questions as a quick comprehension check for the class.
- **Find material at the right level (Intermediate learner):** Grade the difficulty of unfamiliar content and generate questions that expose exactly which parts you did not follow.

## Strengths

- Studies material you actually want to watch instead of assigned content
- Combines level assessment and question writing in one step
- Lightweight extension — around 40 KiB
- Developer states no data collection and no data selling
- Free to add from the Chrome Web Store

## Limitations

- No ratings or reviews yet, so quality is unproven
- Last updated in January 2023 and still at version 1.0
- Very small install base (roughly 18 users)
- Full lesson generation depends on the video having usable subtitles or text
