KingAI BrowserAN AI AUTOMATION BROWSER BUILT ON CHROMIUM 151
From recording web video and working with page text to isolated profiles, synchronized windows, and AI automation, KingAI Browser puts everyday tools into the browser itself.
Built into the browser, not bolted on with fragile page scripts
SIX CAPABILITIES
Each capability addresses a real workflow: fewer extensions to install, fewer scripts to maintain, and more reliability from the browser itself.
Hover over a supported video to start or stop recording. The control follows the player without covering it, and the finished file is saved locally.
When a website blocks selection, copying, or the context menu, explicit shortcuts still let you work with real DOM text on the page.
Create, edit, group, and launch isolated profiles in a native manager. Each profile keeps its own user data, cookies, proxy, and settings.
Key identity, graphics, audio, font, network, and hardware signals are handled in Chromium and Blink. Input behavior is shaped at the browser layer.
Control multiple browser windows from one lead window. Page input uses protected Chromium interfaces; browser controls use internal APIs.
Record a real task as a reusable Skill. The built-in Agent helps adjust to page changes and troubleshoot playback.
SOURCE-LEVEL CONSISTENCY
KingAI Browser changes fingerprint surfaces in Chromium and Blink, keeping identity, language, time zone, proxy region, hardware, and graphics signals aligned. Each profile has separate data and noise keys.
REAL INPUT SIGNALS
Humanize operates in the browser input layer. Along with natural paths and timing, it supplies realistic pressed-button and pressure values to CDP mouse events.
| Signal | Chrome + Playwright | KingAI Browser | How it works |
|---|---|---|---|
| reCAPTCHA v3 | 0.1 bot | 0.9 human | Server-side test in a specific environment |
navigator.webdriver | true | false | Chromium / Blink source changes |
| UA / Client Hints | Fixed browser defaults | Per-profile, internally consistent | Cross-checks brand, version, and platform |
| CDP Error stack detection | Detection hook may fire | Detection side effect blocked | V8 Inspector protection |
| Mouse press signal | buttons / pressure often default to 0 | buttons 1 · pressure 0.5 | Explicit values in the Chromium input layer |
| Mouse movement and click | Straight paths or fixed points | Curved paths and natural timing | Browser-level humanize |
| Typing behavior | Instant text entry | Rhythm, corrections, and backtracking | Browser-level humanize |
| Profile consistency | Requires manual assembly | Checks across surfaces | Source changes and pre-launch validation |
* The 0.1 / 0.9 comparison comes from a particular setup, network, and test procedure. It does not guarantee results on other sites or with other risk checks. Proxy quality, account history, and actual behavior also matter.
ONE ACTION, MANY WINDOWS
Clicks, scrolling, keyboard input, Chinese text entry, tabs, and address bar actions can be synchronized in real time. Each follower keeps its own fingerprint, proxy, and cookies.
RECORD ONCE. REPLAY WITHOUT LIMITS.
Complete a workflow once and save it as a reusable Skill. Replay it in different fingerprint profiles without setting everything up again.
BUILT-IN AGENT
External agents can discover saved Skills, read their parameters, start runs in isolated profiles, check progress, cancel jobs, and receive structured results and controlled artifacts.
BUILT FOR REAL WORK
KingAI Browser and its free profile manager continue to evolve.
