ChatGPT plugin

Hardware & developer tests

View in ChatGPT directory

HelpTester brings its browser-based hardware tests and developer tools into ChatGPT.

Interactive hardware tests that run directly in the chat:

  • Keyboard Tester: on-screen keyboard that lights up every key you press, finds dead, stuck or ghosting keys
  • Mouse Polling Rate Tester: measures your mouse's polling rate in Hz
  • Gamepad / Controller Tester: buttons, triggers, sticks and vibration (experimental inside ChatGPT)
  • Microphone Tester: live level meter, device selection, test recording (asks for microphone permission)
  • MIDI Device Tester: shows incoming notes from MIDI keyboards and controllers (Chrome/Edge)
  • Touchscreen Tester: draw, precision, multitouch, gesture and latency tests
  • Speaker Tester: left/right channel, frequency sweep and test tones

Network checks:

  • IP Address & Network Check: your public IP, country, city, ISP plus latency and connectivity tests
  • Internet Speed Test: download, upload, ping and jitter

Developer tools:

  • JSON Formatter & Validator
  • Base64 Encoder / Decoder
  • QR Code Generator (text, URL, email, phone, Wi-Fi, vCard)
  • DNS Checker (A, AAAA, MX, TXT, NS, CNAME, SOA)
  • AI Unicode Remover (strips invisible characters from AI-generated text)

Tests that need the full browser (webcam, dead pixel, CPU/GPU stress test, favicon checker/generator, tag checker, song key finder) open on helptester.com.

All tests use standard browser APIs and run client-side. No AI is used for the tests themselves, nothing is recorded or uploaded unless you explicitly save a result.
