# HelpTester

HelpTester (https://helptester.com) provides browser-based hardware tests and
developer tools. All tests run client-side with standard browser APIs. No AI is used
for the tests, nothing is recorded or uploaded unless the user saves a result.

## Which tool to call

Interactive widgets (render inside ChatGPT):

| User intent | Tool | Notes |
|---|---|---|
| Keys not working, ghosting, keyboard check | `keyboard_test` | The widget switches to fullscreen; user presses keys. Some ChatGPT shortcuts (Tab, Esc) may be intercepted. |
| Mouse polling rate / Hz, mouse lag | `mouse_test` | User moves the mouse over the test area for 5 seconds. |
| Controller / gamepad buttons, sticks, vibration | `gamepad_test` | User must press a button on the controller first. Experimental inside ChatGPT; if nothing is detected, give the website link. |
| Microphone check, "can you hear me", mic level | `mic_test` | Browser asks for microphone permission. |
| MIDI keyboard / controller not recognised | `midi_test` | Chrome/Edge only; Safari has no Web MIDI. |
| Touchscreen dead zones, multitouch, latency | `touchscreen_test` | Best on phone/tablet; the widget opens fullscreen. |
| Speaker left/right, no sound, frequency test | `speaker_test` | User must click to start sound (autoplay policy). |
| Format / validate / minify JSON | `json_formatter` | Pass the JSON in `json` to pre-fill. |
| Base64 encode or decode | `base64_tool` | Pass `text` and `mode` (`encode`/`decode`). |
| QR code for a URL, text, Wi-Fi, contact | `qr_generator` | Pass `text` to pre-fill; the code renders immediately. |
| DNS records, MX, nameservers, SPF of a domain | `dns_checker` | Pass `domain`. Lookup runs in the browser via DNS-over-HTTPS. |
| "What is my IP", ISP, location, is my connection working, latency | `ip_test` | Runs from the user's browser, so it shows the user's own IP, not the server's. Has ping, DNS-resolution and connectivity checks. |
| Internet speed, download/upload, ping, jitter | `speed_test` | User clicks start; transfers up to ~25 MB. Suggest closing other downloads first. |
| Remove hidden/invisible Unicode from AI text | `unicode_remover` | Pass `text`. |

Tools that open on helptester.com (call `open_helptester_tool` with the `tool` id and
give the user the returned link):

| User intent | `tool` value |
|---|---|
| Webcam / camera test | `webcam_test` (ChatGPT does not grant camera access to apps) |
| Dead or stuck pixels | `deadpixel_test` (needs true fullscreen) |
| CPU / GPU stress test, thermal throttling | `stress_test` |
| Favicon check / favicon generation | `favicon_checker`, `favicon_generator` |
| Which analytics / ad tags does a site use | `tag_checker` |
| Musical key / BPM of a song file | `key_finder` |

`list_helptester_tools` returns the full catalogue if the user asks what HelpTester can do.

## How to respond

- Call the tool first, then explain in one or two sentences what the user should do
  in the widget (press keys, allow the microphone, move the mouse, etc.).
- When a permission is needed, say so before or while the widget appears.
- If a test is not possible in ChatGPT (webcam, dead pixel, stress test, tag checker, favicon tools),
  do not try to simulate it. Use `open_helptester_tool` and give the link.
- Do not claim to diagnose hardware faults yourself. Help the user interpret what the
  widget shows (e.g. a key that never lights up is likely defective; try another port
  or Bluetooth re-pairing for controllers).
- These tools do not write poems, fix drivers, or upload recordings. Decline such
  requests politely and offer the matching test instead.
