## Twee

Twee is built around a simple idea: language teachers spend hours preparing materials, and much of that work is repetitive. The platform wraps AI generators around the 40+ recurring tasks of a language classroom — writing a text on a topic, producing a dialogue, building a matching exercise, replacing words with gaps, drafting open comprehension questions, listing pros and cons, or finding quotes and interesting facts for a warm-up. Each output can be tuned to a CEFR level from A1 to C2, and Twee states support for roughly ten target languages.

Beyond generation, Twee handles delivery and feedback. Creations can be exported as PDF or Word documents, pushed into Google Docs or Google Forms, or shared as Twee's own interactive assignments through a link. The AI assessment layer evaluates student answers — including open-ended written responses and gap-fill items — and returns feedback, which is the part teachers most often describe as the biggest time saver. A management area brings lesson planning, assignment organisation, student accounts and class rosters together in one place.

Twee also publishes free, ready-made ESL lesson plans and grammar worksheets built on the same CEFR-aligned, interactive format. The platform is aimed at private tutors, school teachers, teacher trainers and language schools working with mixed-ability groups.

**Pricing & Plans:** Twee uses a freemium model: a free tier covers everyday generation, a Pro plan is offered with a promotional entry price, and larger plans are available for schools and teams including contact-for-pricing options. Check the pricing page for current limits and rates.

- **40+ CEFR-aligned generators:** Reading, vocabulary, grammar, speaking and writing tools that create exercises at A1–C2 level, in around ten target languages.
- **Interactive assignments:** Share a creation as a link so students complete it online instead of on paper.
- **AI assessment:** Automatic evaluation of student responses, including open-ended answers and gap-fill tasks, with actionable feedback.
- **Flexible export and sharing:** Download materials as PDF or Word, or push them to Google Docs and Google Forms.
- **Class and assignment management:** Organise lessons, assignments, student accounts and classes from a single dashboard.

**Strengths:** Broad coverage of the routine tasks a language teacher actually does, rather than one narrow generator; CEFR leveling on the whole library makes it easy to match material to learners; AI grading of open-ended answers saves real marking time; Free ESL lesson plans and worksheets are usable without generating anything yourself

**Limitations:** Generated content still needs a teacher's review for accuracy and tone; Output quality depends on how specific your prompt or source text is; Best value requires a paid plan for heavier or classroom-wide use

## Viduu

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.

- **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.

**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

**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
