Human Typing Simulator

Simulate realistic human typing on any website. Configurable WPM, natural timing, QWERTY typo simulation, and keyboard shortcuts.

⌨️Human Typing Simulator - Type Like a Human, Not a Robot Paste your text. Click your target field. Press Start. Watch it type itself - character by character, at human speed, with natural rhythm, realistic hesitations, and even occasional typos that get corrected on the fly. Whether you're filling out forms, writing in a web editor, or need text to appear as if someone typed it in real time - Human Typing Simulator handles it seamlessly on any website, in an interface available in 10 languages. WHY THIS EXTENSION EXISTS Many websites and platforms detect when text is pasted all at once and either block it, flag it, or format it incorrectly. Some tools require you to type content manually for it to register properly. Copy-pasting into rich text editors often strips formatting or breaks the editor's internal state. Human Typing Simulator solves all of this. It simulates actual keystrokes - one character at a time - the way a real person would type, including the natural speed variations, micro-pauses between sentences, and occasional finger slips that make typing feel authentic. HOW IT WORKS Copy the text you want to type Click the clipboard icon in the popup to paste it in Click the target field on the page (a textarea, input box, or rich text editor - including ones inside an iframe, common on WordPress and other CMS platforms) Press [ Start Typing ] - or use the keyboard shortcut Alt+T The extension begins typing one character at a time into the active field, using real keyboard events that websites and JavaScript frameworks treat as genuine user input. A floating ⌨ activation button appears whenever you click or focus a recognized input field. Click it to open the extension popup with that field already detected - no need to open the popup first. FEATURES Accurate, Self-Correcting Timing Engine Typing speed follows a Gaussian distribution - some characters come faster, some slower, just like real human rhythm. The engine continuously tracks its own pacing (including time spent on punctuation pauses and typo corrections) and self-corrects on the fly, so the WPM you set is the WPM you actually get - not just a rough floor. Speed ranges from 20 to 600 WPM, with one-click presets (Slow, Normal, Fast, Max) for common speeds. Above 240 WPM, a notice reminds you that results can look less human and vary by site. Sentence and Paragraph Pauses After a period or exclamation mark, the typer pauses - like a person thinking about their next sentence. After a paragraph break, it waits longer, simulating the natural rhythm of composing text. Pause length scales with your chosen speed, so a 240 WPM run isn't held back by the same fixed pauses used at 60 WPM. QWERTY Typo Simulation When "Simulate Typos" is enabled, the extension occasionally types a nearby QWERTY key instead of the intended character - then catches the mistake, deletes it, and types the correct character. The adjacent-key algorithm mirrors real typing errors: "e" might become "r", "s" might become "a". This now works correctly with accented and non-Latin text too (Vietnamese and others), not just plain ASCII. The error rate is fully adjustable (0–20%), and is a completely independent setting from speed variation - turn typos off without losing natural speed variation, or the reverse. Cursor Lock While typing is in progress, mouse clicks on the page cannot move the text cursor. This prevents accidental position jumps that would cause text to be inserted in the wrong location. Live Progress, Speed & ETA A progress bar in the popup shows how far through the text the typer has reached, alongside the actual WPM being achieved and an estimated time remaining. The floating on-page action bar shows the same at-a-glance progress and ETA right next to Pause/Stop, so you don't need the popup open to see how a run is going. The extension icon badge shows live percentage progress too - visible even while you're looking at a different tab. Works on Rich Text Editors The extension uses three parallel insertion methods: For contenteditable editors (Notion, Medium, Quip, Trix, etc.): uses execCommand('insertText') which generates events the browser marks as trusted - the same trust level as real keyboard input. For Google Docs: dispatches keyboard events directly into the hidden text event iframe that Google Docs uses to capture input, bypassing the canvas layer entirely. For standard textareas and input fields (Twitter, Reddit, contact forms, etc.): uses the native HTMLInputElement setter combined with InputEvent, making it compatible with React, Vue, Angular, and other JavaScript frameworks. Every character insertion is verified and automatically retried once if a site's own script briefly rejects it, instead of silently reporting progress on text that never actually landed. Smart Element Detection The extension automatically detects the focused input element on the page. It checks the active element, looks inside Shadow DOM (for Reddit-style components), and searches inside same-origin iframes - including iframe-based editors used by WordPress and other CMS platforms, not just Google Docs' hidden text-capture iframe. If you click away from the field before opening the popup, the extension remembers the last field you interacted with. Resilient in Background Tabs Switching to another tab while a run is in progress no longer collapses typing speed to a crawl - a background timing mechanism keeps pacing accurate even when the tab isn't in focus, with a brief on-screen note if speed is ever affected. Multi-Language Interface The popup is available in English, Vietnamese, Spanish, French, German, Japanese, Russian, Portuguese (Brazil), Indonesian, and Hindi. It follows your browser's language by default, or you can pick one directly from the popup's language switcher. KEYBOARD SHORTCUTS Alt+T - Start typing (uses last detected field and last pasted text) Alt+P - Toggle Pause / Resume Escape - Stop typing immediately All shortcuts are fully customizable via chrome://extensions/shortcuts. SETTINGS Simulate Typos (ON by default) Occasionally types and corrects a nearby-key mistake, at the Error Rate below. Independent from Natural Rhythm - you can run flat, error-free speed with natural rhythm, or the reverse. Natural Rhythm (ON by default) Adds human-like speed variation between characters. Turn OFF for a near-constant pace per character. Lock Cursor (ON by default) Prevents mouse clicks from repositioning the text cursor during typing. Turn OFF only if you need to interact with the page while typing is in progress. Show Icon (ON by default) Controls whether the floating ⌨ activation button appears when you focus an input field. Turn OFF to hide the overlay entirely and rely on the popup or keyboard shortcuts. Speed (WPM) - Range: 20–600 WPM, Default: 120 WPM Sets the typing speed, with Slow/Normal/Fast/Max presets. The engine self-corrects to actually hit this speed rather than treating it as a loose minimum. A notice appears above 240 WPM as a heads-up that results can look less human. Error Rate - Range: 0–20%, Default: 3% Controls how frequently typos occur per letter (including accented letters). 3% means roughly 1 mistake every 33 letters. Only visible when Simulate Typos is ON. Language Choose the popup's display language, or leave it on Auto to follow your browser's language. Settings are saved automatically via Chrome sync storage - your preferences persist across browser sessions and devices. FLOATING ACTIVATION BUTTON Whenever you focus a recognized input field, a small ⌨ button appears near the top-right corner of that field. Clicking it opens the extension popup with that field already connected - no need to open the popup first and lose focus on the target field. While typing is active, the ⌨ button is replaced by a compact progress/ETA readout plus [⏸ PAUSE] and [■ STOP] quick-action buttons - so you can check progress, pause, or stop directly on the page without opening the popup. The button repositions itself as you scroll or resize the window, always staying near the active field. PRIVACY Human Typing Simulator does not collect, transmit, or store any of your data on external servers. The text you paste into the extension lives only in your browser's local storage for the duration of your session. No user accounts, no tracking, no telemetry.
