nukerai

Type passages into any text box with realistic, human-like cadence. Works on Google Docs, Gmail, and any site with a text field.

Realistic, human-like typing into any text box on the web. Most typing automation tools betray themselves the moment you look at them — characters appear in perfectly even bursts, with no hesitation, no rhythm, no second thoughts. nukerai aims for the opposite. It types one keystroke at a time, with the cadence, pauses, and tiny imperfections of a real person at the keyboard. How it works Click into any text box on the page. Click the nukerai toolbar icon — a draggable "liquid glass" panel appears. Paste the passage you want typed into the Source field. Pick a speed and realism level, then press Start. Works with • Gmail and Google Docs • Twitter / X • Notion, Substack, GitHub PR comments • Standard textarea and input fields on any site • Any contenteditable rich-text editor Nine realism controls — toggle individually, or use a preset (Off → Subtle → Light → Natural → Realistic → Hyper): • Timing jitter — random ±25% variation per keystroke • Punctuation pauses — short breaths on , ; : and longer ones on . ! ? • Thinking breaks — occasional micro-pauses between words • Capitalization delay — slight slowdown on shifted letters • Burst rhythm — alternating bursts of speed and brief slowdowns • Word-length sensitivity — long words take longer than short ones • Bigram timing — keys far apart on the keyboard take longer than adjacent ones • Fatigue curve — gradual slowdown after 30+ seconds of typing • Typo injection — occasional typos with automatic backspace corrections (off by default) Panel features • Speed from 20 to 200 WPM, with presets: Slow / Medium / Fast / Blazing • Live stats: characters typed, WPM, elapsed time • Pause / resume mid-run; reset to start over • Drag and drop .txt or .md files directly into the panel • Adjustable panel opacity • Settings, source text, and panel position persist across sessions Pricing • Free — 500 words per calendar month • Pro — $8 per month, unlimited typing, cancel anytime Payment is processed by ExtensionPay through Stripe.

Privacy nukerai does not collect, transmit, or store any of your typing content outside your browser. Source text, settings, panel position, and your monthly word counter live in chrome.storage.local on your machine. The extension makes one outbound network call: to ExtensionPay's API, to verify subscription status. ExtensionPay sees your email; never the text you type. Known limitations • Some high-security forms (banking, captcha-gated fields) may reject synthetic keystrokes. • Google Docs internals occasionally change; if Docs typing breaks, an extension update typically restores it. • Restricted pages (chrome://, the Chrome Web Store itself, and the built-in PDF viewer) cannot host the panel.
