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.

Be sure to dig deep as all of with the functionality doesn’t jump out. AI chat, notes, maps, cool browse history. Worth a serious look. ### 5/5 — Safety and privacy *2023-07-26* Lots of potential here. See arrival times of others without tracking their every move like some apps do. Meeting others gets much more efficient also. Safety, efficiency and privacy seem like a good combination. ### 5/5 — Really good, some quirks *2022-02-12* Love the app. ETA is accurate and let's people know when I arrive, which is handy. Sometimes the beacons don't show the address until I tap on one. The panel on the bottom can get confused when I try to scroll it. ### 4/5 — Missing 1 feature but great otherwise *2022-02-12, version 1.1.0* To the people who made this app. I'm on the road a lot for work and I use beacon to let my wife know I'm safe. My 1 request is to have navigation directions like other map apps. Thank you for making a great app. ### 5/5 — It's been a great family tool! *2022-02-11, version 1.1.0* I was introduced to this app by a friends who has kids. I have a new teenage drive and this helps calm my heart. I wish I could see his precise location while he's driving, but getting ETA updates and notifications when he arrives has given me great peace of mind. ### 5/5 — Great for family reunion *2022-02-10* I first tried this app for a family reunion at a beach house. We all shared our ETA and could see everyone as they approached and even could see when people arrived. It was very cool. I'll be using this for all my long drives. ### 5/5 — Safety and privacy *2021-10-20, version 1.1.0* Lots of potential here. See arrival times of others without tracking their every move like some apps do. Meeting others gets much more efficient also. Safety, efficiency and privacy seem like a good combination. ## Frequently asked questions about Jatter ### What makes Jatter private?
