Ask anything and get instant answers, delivered as rich, visual results — full recipe cards, curated event listings, news briefings, and workout plans — powered by the latest models from leading AI labs. ASK ANYTHING, ANYTIME Your AI assistant helps you: • Write emails, messages, and social posts • Draft essays, resumes, and cover letters • Summarize articles, notes, and documents • Translate languages instantly • Explain difficult topics simply • Brainstorm ideas and make plans • Write and debug code ANSWERS YOU CAN SEE Specialized AI agents work like experts on call — each agent turns your question into a finished, visual result: • Recipes — complete cards with ingredients, steps, and photos • News — fresh headlines pulled from the live web, with sources • Events — what's happening near you, with dates, venues, and links • Workouts — structured training plans built for your goals • Web search — real-time answers grounded in current information, not stale training data INTELLIGENT UI — ANSWERS YOU CAN TAP Some questions deserve more than text. Intelligent UI builds a working mini app right inside your answer — tap it, drag it, expand it full screen: • Calculators — loans, budgets and splits, with sliders you can drag • Converters — units and measurements, instantly • Timers — countdowns, intervals and workout rounds • Diagrams — processes, cycles and how things work, animated step by step • Quizzes and flashcards — test yourself before an exam • Games — a quick round of tic-tac-toe against AI or a friend AN ASSISTANT THAT REMEMBERS Aster learns your preferences, goals, and context from your conversations — so every answer gets more personal and more useful over time. No repeating yourself. ROUTINES ON AUTOPILOT Set a routine once — "morning news at 8am," "weekly meal ideas every Sunday" — and Aster runs it on schedule.

MADE FOR EVERY DAY An AI assistant that fits how you actually live: • At work — draft the email, summarize the thread, prep for the meeting • Studying — explain the concept, check the essay, quiz yourself before an exam • At home — plan dinner, build the shopping list, sort out the week WHY ASTER • The latest AI models, chosen for the right task • Rich visual answers — not just walls of text • Interactive mini apps built right into your answers • Real-time web search with sources • Memory that personalizes your experience • Scheduled routines with instant notifications • Simple, clean, and easy to use • Free to start, with premium plans for power users FREQUENTLY ASKED What is an AI agent? An AI agent is more than a chatbot. It takes your request, works out what's needed, pulls in live information, and hands back a finished result. Ask Aster for dinner and you get a recipe card — not a wall of text to sift through. How is this different from a normal AI chat app? Most AI chat apps and chatbots stop at text. Aster's agents return real, usable results — even interactive mini apps — remember what matters to you, and run on a schedule so you never have to ask twice. Is the AI app free? Yes. AI chat, agents, and routines are free to start. Pro unlocks live web search, more agents, and higher usage limits. Do I need an account? Sign in once to sync your chats, memory, and routines across every device. What can I ask AI about? Anything — writing, studying, coding, planning, cooking, training, or catching up on the news. Just ask AI and get an answer you can actually use. The more you use it, the better it knows you. Download Aster — the AI assistant and AI agent for recipes, workouts, news and everyday answers.
