Everything you need to type naturally

Whether you are pasting text, running a demo, or just do not want to type something twice, Keyflow makes it look completely real.

Natural rhythm engine that looks genuinely human

Keyflow does not type at a fixed speed. It varies between keystrokes, slows on harder words, and occasionally makes and corrects mistakes, exactly like a real person at a keyboard.

Custom WPM

Set any speed from 15 to 300. Fixed rate or variable rhythm, your call.

Accuracy

Mistake simulation

Types wrong, pauses, backspaces, corrects itself. Frequency is fully adjustable.

Rhythm

Typing drift

Subtle timing variation on every keystroke. No two characters hit the same interval.

Realism

Smart pausing

Slows at commas, stops at periods, hesitates on long words. Just like a real reader.

Three steps and you are running

No account needed for the free tier. No complicated setup. Just install, paste, go.

1. Install the extension

Download the zip, unzip it, go to chrome://extensions, enable Developer Mode, and load the folder. Takes under a minute.

2. Paste your text and configure

Open the extension popup, paste your text, and set WPM, mistakes, and drift to match your style.

3. Click into any field and hit Run

People actually use this daily

Been using it for every long-form assignment this semester. Set it to 65 WPM with mistakes on and my prof has never flagged anything. Actually saves my life during crunch week.

Tried like 4 other tools before this. They all type at a flat speed and get caught immediately. Keyflow actually varies, pauses at commas, even makes small typos. It feels real.

Installed it in literally 2 minutes. Loaded my essay in, set 75 WPM, walked away. Came back and it was done. The drift feature makes it look so much more natural than anything else.

Honestly did not expect it to be this smooth. Paid, got my key in like 10 seconds, pasted it in, and it just worked. Using it for both English and French assignments now.
