About Catchwords AI
Learning words? Better catch words! Catch them, with the superpower of AI, from photos of a page you are reading, a panel in museum, a road sign, a historical site, a piece of art, of anything really; or from screenshots, news, wikipedia, social media, texts... Not sure where to start? Just set your language level, choose a field of interest, and tap the red aerial net to take a lucky swing. In Catchwords, the words and phrases will always be caught in their natural habitat, with in-depth, context-aware explanation and etymology. No built-in vocabulary lists. No tedious drills or tests. You decide what to catch — by exploring what genuinely interests you. Efficient, engaging, and inspired. Highlights: - Up to ten words and phrases in one catch, just enough to keep it fresh and breezy for you to learn and absorb. - Full text recognition from photo notes and screenshots. - Underline or highlight on your photos and screenshots to tell AI what to catch first. - Catching descriptive and insightful words from photos and images without any text. - Random reading and slideshow for strengthened memorisation. - Managing tags for your collection of words and phrases. - Full editing control over words in your catch list. - Import, export and share word lists in standard json format, with your tags and notes.
