Presenter Overlay

Floating HUD · Sharing Excluded

Invisible to Zoom & Teams Opacity: 85%

📝 Smart Teleprompter

• Introduce architectural shift to event-driven pipelines • Emphasize 4x throughput gain with zero regression • Mention benchmark: 12,000 req/sec on single core • Demo failure recovery under partition

🤖 Ambient AI Co-Pilot

Audience: "How does partition recovery handle write skew?"

AI Suggested Answer:
"Recovery uses distributed vector clocks and deterministic rollback logs, guaranteeing linearizable reads upon partition heal."

Engineered For Presenters

Never get caught flat-footed
during a live presentation.

Designed for engineers, DevRels, founders, and sales leaders who give mission-critical demos.

🫥

Zero-Leak Screen-Share Hiding

Uses native Cocoa-level window flags (NSWindowSharingNone) on macOS. While you read your notes directly over your slides, Zoom, Teams, Meet, Loom, and OBS see absolutely nothing.

🤖

Context-Aware AI Co-Pilot

Silently listens to your live speech and transcribes context. When tough audience questions arise, ask the co-pilot to generate concise answers tailored specifically to what you just demonstrated.

👁️

Natural Eye Contact

Position your notes directly underneath your camera lens. Speak naturally with flawless eye contact without looking down at secondary monitors or paper scripts.

⚡

Rust + Tauri Lightweight Core

Built on Tauri v2 and Rust. Uses under 30MB of RAM and virtually 0% CPU. No stuttering or frame drops during GPU-intensive screen shares or heavy code compilation.

🎨

Stage-Ready Customization

Adjust window opacity from 0% to 100%, scale fonts up to 32px, and toggle high-contrast modes to ensure perfect readability in any studio or stage lighting environment.

🔒

100% Sandboxed Privacy

Zero telemetry, zero third-party analytics. Notes are stored in local sandbox storage, and AI prompts use your own direct Gemini API key without intermediary servers.

Workflow

How Presenter Overlay works.

Four seamless steps from setup to keynote delivery.

1. Launch & Position

Open Presenter Overlay. Move the semi-transparent HUD right below your webcam or over your presentation window.

2. Start Screen Share

Share your full desktop or application window on Zoom, Teams, or Meet. Cocoa window filtering ensures audience invisibility.

3. Ambient Transcription

Turn on the microphone co-pilot. The engine automatically captures your talking points as live context.

4. Ace The Q&A

When an audience member asks a complex question, type or speak the query to receive instant, fact-checked talking points.

Target Audiences

Built for high-stakes speakers.

See how teams across tech leverage Presenter Overlay.

💻

Developer Relations

Paste terminal commands, architectural talking points, and API secrets right over your IDE without risking accidental audience disclosure.

💼

Solutions Engineers

Keep competitive pricing sheets, SLA specs, and feature comparison matrices handy during customer demos.

🚀

Founders & Executives

Deliver pitch decks and investor updates with flawless confidence and uninterrupted eye contact.

🎓

Online Educators & Streamers

Record crisp tutorial videos in OBS or Loom with speaking cues positioned right near the lens.
