Start free with Rova and put a whole AI toolkit in your pocket for study, work, creative projects, inspiration, and fun. AI Chat, AI Image Generator and Editor, Fashion Virtual Try On, Web Search, Deep Research, Document Tools all in one app, so you can write, create, and research in seconds. One assistant, every task. AI Assistant for Every Task Rova runs on the newest advances in AI and plays two roles at once: a creative partner when you are making something, and a research assistant when you need answers you can trust. AI Chat & Deep Thinking: Talk to an assistant that follows context and picks up on nuance instead of losing the thread. Hand it something hard, like code, math, or a logic puzzle, and Deep Thinking kicks in to work the problem step by step before answering. AI Image Generator & Editor: Describe the picture in your head and watch it appear in seconds. Not quite right? Say what to change and the built-in AI Image Editor reworks it, no design skills needed. Virtual Try-On: Know how it looks on you before you spend a penny. Upload a photo, put on any outfit, style, or look in seconds, and shop fashion with confidence. Visual Intelligence: Give Rova your camera and it reads the world around you. Identify an object, translate a sign or menu, or solve a handwritten equation from a single photo. Document Analyzer: Stop skimming hundreds of pages. Drop in a PDF, Excel sheet, Word document, or text file and ask for what you actually need, whether that is a summary, a specific clause, or the numbers that matter. Web Search & Deep Search: For anything happening right now, Web Search pulls live news, scores, and market moves straight into your chat. For anything worth digging into, Deep Search reads across many sources and comes back with a detailed, fact-checked report. Local AI: Run capable models directly on your phone. Nothing you type is sent anywhere, and once a model is downloaded the assistant keeps answering with the internet switched off, whether you are on a flight, underground, or out of signal. KEY FEATURES OF ROVA - Smart AI Assistant: A versatile assistant on standby for whatever you throw at it. - Visual Creativity: Generate images, edit them by description, and try on any look with Virtual Try-On. - In-Depth Research: Web Search for quick live answers, Deep Search when you need the full picture. - Image & Text Analysis: Read photos and documents instantly and get straight to the insight. - Private & Offline Mode: On-device AI that works with no internet and keeps your data on your phone.
