Overview

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.
