Free AI assistant that helps you pick the right hardware test, explains results, and walks through keyboard, mouse, screen, and audio diagnostics in 10 languages — in-browser, no sign-up.
01Start the live tool
Open the test area and follow the on-screen controls before drawing conclusions.
02Run one clean pass
Keep input steady so the result is useful for comparison and troubleshooting.
03Repeat the check
Run another pass if browser focus, permissions, or hardware settings changed.
04Compare with related tools
Use the related diagnostics to confirm whether the issue belongs to the device or the browser.
Yes. The assistant is free, requires no account, and has no paywall. A rate limit of 12 messages per minute per visitor exists only to keep the service fast and prevent abuse — it resets every minute.
Which AI model powers the assistant?
The assistant runs on a Groq-hosted large language model. Groq provides sub-second inference speeds on open LLMs, which is why answers arrive in about a second. The model is not GPT-4 or Claude Opus — it is a mid-sized LLM tuned for fast, focused responses within our hardware-testing domain.
What languages does the AI assistant support?
Ten languages: English, Spanish, French, German, Indonesian, Japanese, Korean, Portuguese, Arabic, and Russian. Tap the 🌐 button in the chat header to switch. Tool links in the AI responses automatically route to the localized version of the site where available.
How is my AI Assistant conversation handled?
Recent chat history is stored in your browser localStorage and can persist after a reload. When you send a message, that message and recent context are sent through the KeyboardTester.click endpoint to Groq to generate the reply. The application does not intentionally keep a server-side transcript, but you should not submit passwords or other sensitive information.
What can the AI assistant help me with?
It is scoped to hardware testing on KeyboardTester.click: picking the right diagnostic tool based on your symptom, explaining technical terms like ghosting or N-key rollover, interpreting test results, and routing you to the correct test page. It will decline off-topic questions (politics, coding, homework, general trivia) — for those, a general AI chatbot like ChatGPT or Claude is a better fit.
Does the AI replace the test tools themselves?
No. The tools are the actual diagnostic. The AI assistant is a guide layer on top — it tells you which test to run and what the numbers mean, but the testing itself happens in the browser-based tools (keyboard tester, mouse tester, screen tester, etc.).
