Description

From the listing uploaded by “appupdater”.

What if your AI actually understood your life — without giving your life away? Jatter is a private, encrypted AI browser that connects what you browse, save, write, and ask so your AI can give you answers that are personal to you. Instead of starting every conversation from zero, Jatter can build useful context from the information you choose to share with it. That means better answers, less repetition, and an AI that becomes more useful over time. AI THAT KNOWS MORE ABOUT YOU — PRIVATELY • Get answers about your life using your own private information. • Understand your finances by asking questions about supported authenticated financial pages. • Turn notes into answers instead of digging through them yourself. • Find things you’ve seen before without remembering exactly where you found them. • Explore places with AI and get help discovering what matters to you. • Connect the dots across your browsing, notes, and AI conversations. IMAGINE ASKING: • “Where am I spending the most money?” • “What was that product I looked at last week?” • “What were the key ideas in the notes I saved?” • “What do I already know about this topic?” Jatter is designed to make questions like these possible without forcing you to hand over your personal data to build an advertising profile. PRIVATE BY DESIGN Personal AI should be personal — not surveillance. Jatter uses client-side encryption for supported personal data and AI conversations, helping keep your information private and under your control. START FOR FREE • Learning from 1 website • Up to 3 notes per month • Access to basic AI models • Private, encrypted personal data JATTER PLUS — $10/month or $100/year • Unlimited websites for permission-based learning • Unlimited notes • Premium AI models • Personalized answers across the websites you visit • Place photos and reviews in AI Maps • The same private, encrypted experience You decide which websites Jatter can learn from, and you can start using it without paying anything.
