HumanType by Swalter Factories

Here's your store description, ready to copy and paste:

HumanType makes your text look like it was typed by a real person — not pasted. Paste any text into the extension, click a field on the page, and watch it type out character by character with natural rhythm, realistic mistakes, and human-like pauses.
Features:

Adjustable typing speed (20–120 WPM)
Variance slider — adds natural rhythm so it never sounds robotic
Realistic typos — occasionally types the wrong key, then backspaces and self-corrects
Whole-word mistakes — at high variance, entire words get mistyped and retyped
Stealth mode — speed drifts unpredictably throughout so it never holds a suspicious steady pace
Thinking pauses — random mid-sentence hesitations like a real person searching for a word
Punctuation pauses — natural delays after periods, commas, and question marks
Live time remaining estimate based on your actual typing pace
Works on Google Docs, Gmail, Outlook, and most text fields
All settings are saved automatically between sessions

Perfect for students, writers, and anyone who wants their typing to look authentically human. No data is collected, no accounts required — everything runs locally in your browser.
