About this app

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.

Ratings and reviews

This things UI feels like it was made by a person who's only ever tech device was an apple watch, or who time traveled to us from 2001. Everything is slow, everything is clunky. There is nothing unique here, you get the usual ai flavors (gemini, gpt etc). If you enjoy playing with the browser more than the site you are browsing, get this (and some help).

I like ArcSphere because it's an AI-native decentralized application (dApp) and I like the spatial design. Is there a Delete feature for ArcSphere AI Navigator chat history

I'm all for innovation and I'm not content with the current browser styles that dominate phones, but I just don't get it. from what I can tell the sphere is meant to act like a tab list. But when I tap an app it zooms into a grid layout and I have to tap again to open the tab. Now, once I'm in a tab, I can go back to the grid, but I can't for the life of me work out how to go back to the sphere without reopening the app. Nothing makes sense, maybe someone can try and make it make sense to me?
