Auto-typer for Google Docs · Slides · Word Online
Every other auto-typer
types your words.
Cadence writes better ones first.
Paste a draft. Cadence rewrites it in a human voice, then types that version into your document keystroke by keystroke — typos, pauses, backspaces and all. The revision history tells the same story your prose does.

Your draft
The industrial revolution fundamentally altered the relationship between labor and time. Workers no longer measured their day by tasks completed, but by hours surrendered to the clock.

Cadence output
The difference
A perfect typing rhythm can't save robotic prose.
Existing auto-typers solve half the problem. They reproduce the keystrokes of a human and the sentences of a machine — a document that was clearly typed by a person who writes like nobody alive. Cadence fixes the text and the typing together, because they're the same problem.
01
Paste anything
A ChatGPT answer, a half-finished draft, notes from a lecture. Cadence doesn't care where it came from.
02
It gets rewritten first
This is the part nobody else does. Before a single keystroke, your text is rewritten in a specific human voice — varied sentence length, plainer transitions, the small asymmetries real writers leave behind.
03
Then it gets typed
The same persona that chose the words chooses the rhythm. A deliberate writer types slowly and pauses at sentence ends. A sprinter doesn't. Voice and cadence finally agree.
One way to get it into the document.
Install the extension, keep the Doc open in Chrome, and let Cadence type.
Cadence Live
Watch it happen.
A Chrome extension that types straight into Google Docs while you do something else. Trusted keystrokes, real revision entries.
The engine
Built from keystroke research, not a random delay.
Revision history is a time series. If yours is uniform, it reads as synthetic to anyone who looks — and tools that replay a document's full edit history are one click away in the Chrome store. Cadence models the statistics of real typing rather than approximating them.
log-normal
Inter-key timing
Real typing intervals aren't a bell curve — they're mostly fast with a long tail of hesitation. Cadence samples the right distribution instead of jittering a fixed delay.
52 wpm
Median human speed
Calibrated against a public corpus of 136 million keystrokes from 168,000 typists, including how error rates shift with speed.
typo → fix
Error modelling
Mistakes land on adjacent QWERTY keys, get noticed after a beat, and are corrected with backspace — the pause-then-burst signature of a real correction.
burst / pause
Macro rhythm
Fluent phrases run fast; sentence and paragraph boundaries collect the long thinking pauses. Nobody types at a constant rate.
Revision preview
See the edit history before you commit to it.
Cadence renders the exact timeline your document will have — every keystroke, pause and correction, on a scrubbable track — before a single character reaches Google. If it doesn't look like you, change the persona and render it again. No other tool shows you this.

Questions.
How is this different from just pasting?+
A paste is one atomic event in your document's revision history. Anyone replaying that history sees a finished essay appear in a single instant. Cadence produces thousands of small, individually timestamped edits instead.
Does the extension need scary permissions?+
Yes, and we'd rather say so up front. Producing genuine keystrokes requires Chrome's debugger permission, which shows a persistent banner while a session runs. Anything that avoids that banner is dispatching synthetic events Google Docs can quietly ignore.
What does the humanizer actually change?+
Sentence-length variance, transition phrasing, hedges and asides, and the overly balanced structure that generated text tends toward. You review the rewrite before typing starts — nothing goes into your document unseen.
Can I make it type like me specifically?+
That's what Writer's typing fingerprint does. Cadence measures your real speed, error rate and pause pattern from a short sample and fits the engine's parameters to you instead of to the population median.
