StealthAI
StealthAI handles site automation on pages you already work in. It clicks, types, and scrolls through complicated UIs, helps you set up Stealth Browse, and can open, close, switch, group, and move tabs from the conversation.
Leave a watch agent on a price or a line of text, or run scheduled tasks later without sitting on the page. Time Machine searches your local full-page history. PowerUp Creator builds and installs custom .spu tools. Voice mode lets you talk to StealthAI in realtime.
Use Stealth cloud tokens, a local LLM, sign in with a ChatGPT, Claude, or Grok account, or your own OpenAI, Claude, Gemini, DeepSeek, or Grok key.
An animated mascot that can walk around your browser and desktop, climb on stuff, answer questions, run tasks, and entertain you. #rememberingclippyvibes
PowerUps
PowerUps are first-party Stealth Browse tools you add from Settings. They are not Chrome extensions. Load a custom .spu pack, or run Chrome extensions separately with Manifest V2 and V3.
Open the PowerUps docs. PowerUp API covers custom .spu packs.

Protection
Blocking is built into the browser. You do not install it as a PowerUp or a Chrome extension. The Stealth logo badge is the live blocked count for this page. Click it to pause protection for 15 minutes, 1 hour, 1 day, until restart, or always.

FAQ
Switching from Chrome, VPN versus Tor, what FATAL collects, licenses, PowerUps, and StealthAI.
Stealth Browse is built by FATAL Cybersecurity (FVTAL LLC), the company behind the STEALTH privacy suite. Confirm the publisher at fvtal.com. Download only from browse.stealth.online or the official Android listings, not from third-party mirrors.
Yes. Open Settings → General → Import and pull bookmarks, passwords, and related data from Chrome or Firefox already on this PC. You can do a one-time move or keep-in-sync on an interval. Chrome extensions install under Settings → Plugins: Manifest V3 is the default, and Manifest V2 is a toggle that needs a relaunch, so extensions Chrome dropped can still run here.
Import from Chrome or Firefox. Chrome extensions (V2 and V3).
No. Ad, tracker, and cookie consent blocking, fingerprint controls, WebRTC hardening, Secure DNS, and HTTPS upgrade run in the free browser with no subscription. A VPN does not replace those browser controls. Use built-in Tor for .onion sites, bridges, Snowflake, New Circuit, and New Identity. A WireGuard VPN hides your IP from sites and your ISP, and that tunnel is a separate Stealth subscription, not bundled with the download.
Stealth does not log browsing history, visited sites, VPN connection times, DNS queries, or traffic content, and it does not profile you with analytics or tracking pixels. If you activate a Stealth license, FATAL stores email, license key, and subscription status to validate the key and handle support. Bug reports and debug logging are optional, you review them before they send, and they are used only for troubleshooting.
No. Paste the same STEALTH Pro license in Settings → VPN & License. That key also works in the official Chrome and Firefox Stealth extensions. In Browse it unlocks WireGuard VPN, Split Tunnel, Stealth AntiSponsor, and Private Features such as realtime voice. Everyday browsing, blocking, plugins, and most PowerUps stay available without a key.
PowerUps are first-party tools from Settings → Power Ups, including catalog items and custom .spu packs. Chrome extensions are third-party add-ons under Settings → Plugins, with both Manifest V2 and V3 supported. Split Tunnel and Stealth AntiSponsor need a Stealth license. The rest of the PowerUp catalog does not.
No. StealthAI can click, type, and scroll on live pages, control tabs, run watch agents and scheduled tasks, search local Time Machine page text, and help build PowerUps. Stealth Buddy is a separate beta mascot, not the automation engine. Use Stealth cloud tokens, a local LLM, a ChatGPT, Claude, or Grok login, or your own OpenAI, Claude, Gemini, DeepSeek, or Grok key. Cloud providers only see what you send through the provider you pick.
Yes. Skip the license splash and browse. Blocking, Tor, fingerprint controls, Chrome extensions, profiles, import, and most PowerUps work with no key. WireGuard VPN, Split Tunnel, AntiSponsor, and some Private Features stay locked until you activate a Stealth subscription.
