HumanType

Inject realistic human typing behavior into any text field

HumanType types your content into any focused text field on the web with believable human rhythm — variable speed, inter-key jitter, thinking pauses, burst typing, and realistic typo-then-backspace-retype corrections. It's built for people who record screencasts, demo products live, build tutorials, or just prefer watching text appear the way a human would actually type it. How it works Click the HumanType toolbar icon to open the side panel. Paste or type your content into the editor. Pick markdown or rich-text mode and choose a typing profile. Click Type It. You have a 3-second arm window to click into the target field on the page. HumanType types into that field at the cadence of the profile you picked. Stop anytime with the Stop button. Pause and resume with the Pause button or Alt+P. Typing profiles Student — around 42 WPM, casual with longer thinking pauses Professional — around 62 WPM, steady experienced office typist Rusher — around 75 WPM, fast and sloppy with frequent bursts SpeedBlitz — around 150 WPM, elite competition-level speed Custom — dial WPM, error rate, and rhythm variability yourself Every profile simulates variable speed, inter-key timing jitter, thinking pauses, burst typing, and realistic typo-backspace-retype corrections. Not a flat, robotic loop. Formatting Markdown mode — paste markdown with headings, bold, italic, bullet lists, and numbered lists. HumanType applies the right keyboard shortcuts as it types. Rich-text mode — paste pre-formatted content from another editor and the structure is preserved and replayed. In compatible editors like Google Docs, formatting shortcuts (Ctrl+B, Ctrl+I, heading shortcuts, lists) are applied live as typing happens. In plain textareas and inputs, text types correctly — shortcuts have no visible effect because plain fields don't support them. That's expected, not a bug. Live word highlighter While typing, the editor switches to a read-only preview and highlights the exact word currently being typed so you can follow progress. When typing finishes, stops, or errors out, the editor returns to its normal editable state. Find in editor Press Ctrl+F (or Cmd+F on Mac) while the editor has content to open the inline search bar. All matches are highlighted, and you can jump between them with Prev/Next, the arrow buttons, or Enter and Shift+Enter. Escape closes. Compatibility Plain textareas and input fields — text types correctly Rich-text editors like Google Docs — full formatting support including headings, bold, italic, underline, and lists Framework-controlled inputs (React, Vue, Angular) — plain text works; formatting behavior depends on the editor Why HumanType asks for the "debugger" permission Modern web editors like Google Docs and React-controlled inputs ignore synthetic DOM events. To make typing actually land in those editors, HumanType uses Chrome's debugger API to dispatch real keystroke events into the tab you activate. It is used exclusively for typing into the field you pick during the arm window. Nothing is recorded, no network requests are made, no page content is inspected, and the debugger detaches as soon as a session ends. Privacy HumanType runs entirely on your machine. The content you paste never leaves your computer. There are no accounts, no analytics, no remote servers, and no third parties.
