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.

Stuck on a math problem? Snap a photo and get the full solution with every step explained. Math Solver reads the problem from your camera or photo library and walks you through the solution the way a tutor would. HOW IT WORKS 1. Point the camera at the problem. Printed pages and handwriting both work. 2. Crop the exact problem you want solved. 3. Read the solution step by step, in clean math notation. 4. Ask follow-up questions in chat if something is unclear. WHAT IT COVERS • Algebra and equations • Fractions and decimals • Derivatives and integrals • Matrices and systems of equations • Functions and trigonometry • Word problems MORE THAN MATH Switch to general mode and ask questions from any school subject. Physics, chemistry, biology, history: if it comes up in class, you can ask about it. STUCK ON A STEP? Tap "Explain it" for a simpler explanation, "Similar questions" for practice, or "Be brief" for a short answer. You can also type your own question. ANSWERS YOU CAN TRUST A built-in math engine checks solutions whenever possible. When a solution passes the check, you see a "Verified solution" badge. Everything you solve is saved to History, so you can come back to it before a test. BUILT FOR HOMEWORK Copying an answer will not get you through the exam. Math Solver shows the logic behind every step, so you learn the method while you finish the homework. Use it for a quick homework check or a full study session before a test.
