Windows appStealth AI
Your discreet AI assistant for Windows.
Fast answers, translations and summaries right on your screen – via hotkey and with your own API key. Built for your personal productivity, without switching windows.
stealth-ai.chStealth AI is an AI assistant that runs on your Windows machine and appears on a hotkey. You ask where you are already working and get the answer in a subtle overlay - without switching windows. Which model answers, and where your requests go, is your decision, because you bring your own API key.
Ask without leaving your context
The usual route to an AI answer takes several steps: bring the browser forward, find the tab, copy the text, paste it, copy the answer back. Every one of those steps pulls you out of what you were doing. Stealth AI shortens it to a keystroke - you stay in your document, your mail or your editor.
The answer appears in an overlay on top of your screen that is deliberately restrained. It should be readable and then get out of the way, rather than leaving yet another window sitting in your taskbar.
Your screen is the context
Not everything is convenient to retype as text - a table, an error message, a form, a chart. With Stealth AI you select an area of your screen and ask your question about it directly. What you see, the model sees too.
That makes everyday tasks quick: translate a paragraph, have an unfamiliar term explained, summarise a long passage or work through a problem. The loop stays the same every time - hotkey, a question or a captured area, answer in the overlay.
Your key, your model, your device
Stealth AI works with OpenAI, Gemini and Claude. You store your own API key and decide for yourself which provider answers your requests - depending on where you already have an account, or which model suits your tasks best.
It is mainly a question of control: requests run through your own access with the provider you chose, and you can swap or remove that key at any time. The license is per device, so you install Stealth AI where you actually work with it.
What's inside
Who Stealth AI is for
- 01
You work on a Windows machine all day and switch to the browser far too often just to ask something.
- 02
You regularly read or write in English or another foreign language and need quick translations mid-text.
- 03
You already have API access with OpenAI, Google or Anthropic and want to use it directly on the desktop.
- 04
You want to know which provider your requests run through, instead of leaving that to someone else’s default.
Frequently asked questions
What does Stealth AI actually do?
Stealth AI is a Windows application you call up with a hotkey. You ask a question or capture an area of your screen, and the answer appears in a subtle overlay - without changing programs. Typical tasks are translating, explaining, summarising and solving.
Do I need my own API key?
Yes. Stealth AI uses your own key with the AI provider you configure. That is one extra setup step, but it gives you control over which account and which provider your requests run through.
Which AI models can I use with Stealth AI?
Stealth AI supports OpenAI, Gemini and Claude. You decide which of the three providers to use, and you can switch if another model suits your tasks better.
Where do my inputs go?
To the provider whose API key you configured - that is where the request goes so it can be answered. What a request contains is up to you: the text you type, plus the image if you captured a screen area. You can swap or remove the key at any time.
How many devices does one license cover?
The license is per device: every machine you run Stealth AI on needs its own. If you want to set up several workstations, just get in touch with us.
