ArcSphere: AI Browser
AI Navigator, Beyond Browser
Free · Designed for iPad
ArcSphere is your AI Navigator — not just a browser, but a smart guide through the web.
It understands, plans, and acts — making every visit an intelligent journey.
ArcSphere is an AI Navigator that helps you do more than just view pages.
With context-aware AI, 3D gesture navigation, and a mobile-first design, your phone becomes a thinking companion that understands and acts with you.
AI That Acts, Not Just Answers
ArcSphere’s AI understands what you see and anticipates what you need next.
Summarize articles, write replies, compare pages, or extract key insights — all right on your screen.
Action Ring: Command With a Tap
Tap the page header to reveal the Action Ring — your personal AI menu glowing under your fingertip.
Access grammar checkers, translators, summarizers, or chat with AI using the current page as context.
Your command center, always one tap away.
One Input. Infinite Control.
A single input bar handles search, navigation, chat, and commands.
Enter URLs, search open tabs, talk to AI, or go hands-free with voice input.
Your digital world now moves as smoothly as thought.
End Tab Chaos With Spatial Navigation
Say goodbye to messy tabs.
Glide across a 3D sphere with pinch and scroll gestures —
like spinning a living universe of pages where every tab has its place.
Build Your Own AI Tools With ArcPrompt
Want AI to work your way?
Create your own grammar fixer, translator, or idea generator once — then use it anywhere.
Organize Life With Multiple Spheres
Create focused spaces for work, study, shopping, or personal browsing.
Each Sphere keeps its tabs and chat history separate — like planets in orbit, organized and calm.
Mark Content, Build Knowledge
Highlight text on any page to save as a note.
Use your notes in AI chats to compare, discuss, or synthesize ideas —
turning scattered reading into structured understanding.
AI-Powered Form Filling
When you tap an input field, AI helps you draft, refine, and fill it naturally.
Write emails, comments, or forms — like talking to a helpful partner who types for you.
