# Nuanze > Nuanze is a reading tool for language learners. You paste a sentence or an article in any language. Nuanze marks only the "knots", such as split verbs, fixed expressions and tricky grammar a learner would stumble on, joins the pieces of a split knot with an arc, and gives one short note for each. It does not gloss word by word. Key facts: - Product: Nuanze, a web app (https://nuanze.app). - For: learners who read real texts and want help only where they get stuck. - Languages: any written language, detected from the text. Notes are in English. - Modes: Sentence (one sentence: knots, translation, level and register, cultural notes, reworded versions), Article (a whole text, read paragraph by paragraph), How to say? (English in, 5–7 native versions from formal to intimate). - Later: select any phrase and keep it; it stays marked in the text and in your history. - Known: mark a knot as known; the next readings skip it. - History and Review: every reading is saved and can be reviewed. - Pricing: one plan, €9/month or €90/year, with every feature and every model. A yearly plan costs the same as 10 months. ## Pages - [Home](https://nuanze.app/): product, video, features, pricing and FAQ - [Promo video (30 s, MP4)](https://nuanze.app/media/nuanze-promo-1080p.mp4): knots, Later and Known in the real app - [Video captions](https://nuanze.app/media/promo.en.vtt) ## Terms - Knot: a part of a sentence a learner would not read correctly on their own: a split verb, a fixed expression or a grammar pattern. - Arc: the line Nuanze draws between the pieces of one knot when other words stand between them.
