See everything.
Stay invisible.

A live AI overlay that sees your screen, hears your conversation, and answers instantly — while staying invisible to every screen recorder, proctor, and meeting app.

No credit card required. BYOK forever free.

Built for when it actually matters.

The features that make Stealth feel less like an app and more like a co-pilot.

Invisible to screen share

Your overlay never appears in Zoom, Meet, Teams, QuickTime, OBS, browser proctors, or screenshots. OS-level cloaking on macOS and Windows.

Live transcription

Deepgram Nova-2 streams speech to text with speaker diarization in under 200ms. Or run local Whisper fully offline.

Screen + voice context

Hit one hotkey. It captures your screen, pulls the last 30s of conversation, and asks Claude — all without breaking your flow.

Your own keys

Bring your API keys for free forever. Claude, GPT-4o, Gemini, Ollama — all supported. Prompts never touch our servers.

Skills & knowledge base

Drop your resume, interview notes, or custom playbooks. The AI follows your methodology, not a generic template.

Mac + Windows

Same stealth, same speed, both platforms. Ad-blocker-level invisibility baked in.

How we compare.

Same core features. Different approach to pricing and privacy.

Common questions

How is this different from Cluely?

Stealth has a free BYOK tier, a $99 one-time option, Windows support, and works fully offline with Ollama + local Whisper. Cluely is subscription-only and Mac-only.

Is it actually invisible in screen shares?

Yes. We use NSWindowSharingNone on macOS and WDA_EXCLUDEFROMCAPTURE on Windows — the same kernel-level flags used by banking apps to hide from screen capture.

What's in the free tier?

3 days of full stealth with your own API keys, then text-only chat after that. No signup, no credit card. The free tier is how we prove the product works.

Do you see my prompts?

Only on paid managed tiers (Pro, Pro+, Team), where we proxy LLM calls. Free and Lifetime users talk directly to Anthropic/OpenAI — we never see the content.
