Chameleon is a real-time presenter privacy overlay engineered to assist presenters, sales leads, and engineers during client demos, executive pitches, and webinars. It provides live AI talking points, private teleprompter notes, and smart clipboard formatting visible only to the presenter.

Can Chameleon solve live coding problems on LeetCode, HackerRank, or CodeSignal?

Yes. Chameleon features an instant one-click screenshot capture tool. With a discreet presenter hotkey, Chameleon captures slides or code from your screen, generates clear explanations and talking points, and presents them on your private overlay.

PRESENTER PRIVACY • DEMOS & PRESENTATIONS PRESENTER PRIVACY

The Presenter Privacy Overlay for Company Demos & Presentations.

Q: Is Chameleon free to use?

Yes! Chameleon offers a 100% Free Forever tier that includes presenter privacy exclusion on Zoom, Microsoft Teams, and Google Meet, real-time AI assistance, and private note overlay navigation without requiring a credit card.

Q: How does Chameleon keep notes private during Zoom, Microsoft Teams, and Google Meet screen sharing?

Your Physical Screen

Your Presenter Monitor View

Chameleon floats directly in the center of your screen over your demo. You reference private notes, consult AI models, and view talking points right where your eyes are focused without looking away.

Client & Audience Demo View

Whether delivering a complex enterprise software walkthrough, a pitch deck, or a live product demo, Zoom, Teams, and Google Meet query the OS window compositor. Chameleon excludes its window via native OS APIs, delivering a clean presentation feed to clients.

Discreet Overlay & Transparency

Blend Chameleon directly into your presentation workflow. Keep your slides or code filling the display while Chameleon floats as a translucent presenter teleprompter taking less than 50% of your screen.

Presenter Overlay Architecture

Chameleon renders at your desired opacity directly over your active application. Talking points and AI notes remain crystal clear to your eyes while keeping your focus locked on the audience.

Why Opaque Windows Disrupt Presentations

Standard browser windows completely block your presentation, forcing awkward window dragging or frequent Alt+Tab cycling during demos. Translucent overlay keeps notes seamlessly in your line of sight.

Smart Clipboard Formatting

Present clean snippets effortlessly during live calls. Smart Clipboard Formatting synthesizes clean character input without messy formatting or broken indentation.

How Smart Clipboard Formatting Works

Smart Clipboard Formatting normalizes line endings and removes hidden styling artifacts, ensuring text pastes cleanly into presentation chat windows and demo terminals.

Why Formatting Matters in Live Demos

Pasting rich text into web terminals or presentation chats often introduces unwanted artifacts or broken whitespace. Smart formatting guarantees clean plain-text output.

OS Kernel Pointer Decoupling

With Chameleon, lock the cursor coordinates sent to the screen-sharing video encoder (Zoom, Teams, Meet) onto a fixed code line in your IDE, while allowing your physical hardware mouse to navigate seamlessly on your actual screen.

Keeping Presenter Mouse Focus

During high-profile client demonstrations, maintaining smooth cursor focus prevents audience distraction while you reference presenter notes on your private overlay.

Cursor Focus Lock

Your cursor never morphs into an I-beam or pointing hand when hovering over Chameleon's text boxes or buttons—locking to a permanent, normal arrow on your screen share.

Hardware-Level Cursor Virtualization

Chameleon intercepts OS cursor transformation hooks (NSCursor / SetCursor) before frames are composed for screen capture. When you interact with text boxes and action buttons inside Chameleon, your shared video feed renders an uninterrupted, static default arrow.

Consistent Cursor Rendering

Ensures your cursor maintains a consistent default presentation arrow across all shared screens without flickering over notes.

60-Second Stream Delay &
Instant Demo Pause

Delay your live screen share feed by up to 60 seconds with an instant emergency pause button. If a sensitive notification, secret token, or demo error appears on your screen, pause the stream instantly—your audience stays locked on a safe still-frame while you fix the issue in real time.

Shielded by 30s Delay Buffer • Zero Leaks

AUDIENCE STREAM: 30s Time-Shifted Buffer • Zero leaks broadcasted 100% PROTECTED

Configurable 60-Second Stream Delay Buffer

Chameleon holds outgoing screen capture frames in a configurable hardware-accelerated memory buffer. Choose a broadcast delay anywhere from 5 to 60 seconds, giving you a continuous safety window to catch accidental leaks, unexpected errors, or confidential alerts before viewers can see them.

Instant Emergency Demo Pause & Live Remediation

If an unintended notification, private token, or demo failure appears on your physical screen, trigger the emergency pause shortcut instantly. The spectator video encoder locks onto the last safe frame in the buffer while you dismiss the popup, test your command, or fix the code—resuming seamless broadcast with zero attendee suspicion.

Instant Panic Kill Switch

Need an instant exit? Triggering panic kill immediately scrubs session memory and terminates the process in under 5 milliseconds with zero traces.

Instant 3-Tab Manager

Built for speed and focus. Cycle between documentation, AI chat, and scratchpad notes instantly with 1-click tab controls without UI latency.
