If you know how to send a message on WhatsApp, you know how to use Aster. Zero learning curve. No need to install anything, no need to learn any special commands — just write in natural language.
Aster is purpose-built for busy professionals: physicians (pending reports, patient check-ins), attorneys (court deadlines, hearings), engineers (site inspections, measurements), consultants, and executives. You schedule reminders, track pending tasks, and organize files naturally via WhatsApp. Plus, you get an unconditional 7-day money-back guarantee to test everything risk-free.
No. It works 100% through WhatsApp.
You subscribe with immediate activation and test all features for 7 days. If for any reason you decide Aster isn't for you, simply request a refund and we will return 100% of your money, no questions asked.
Yes, you choose your plan and complete payment for instant access. But your risk is completely zero: you have a 7-day unconditional guarantee with 100% refund available at any time within those 7 days.
Yes, whenever you want, just go to your profile and click 'cancel subscription'.
Yes. We use the official API and we do not read your other conversations.
Your files are sent over a secure connection and kept in private storage with controlled access. Associated information, such as file names, tags, and AI metadata, receives additional protection in the database. Authorized systems and contracted services process file contents to provide semantic search, summaries, and on-demand delivery, so we do not describe this flow as end-to-end encryption. Content is not freely available, but authorized personnel may access it in exceptional operational situations.
Yes! If you subscribe to a plan that allows multiple profiles (like Plus or Premium), you can use the web dashboard to grant permissions. This way, you can share shopping lists or allow another person to receive the reminder alerts configured by you.
If you want to change your current plan, just send an email to contato@getaster.co informing us, and we will change it to the plan you choose.
