Auto-typer for Google Docs · Slides · Word Online
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.

The difference
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
A ChatGPT answer, a half-finished draft, notes from a lecture. Cadence doesn't care where it came from.
02
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
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.
Pick how hands-off you want to be.
Cadence Live
A Chrome extension that types straight into Google Docs, Slides, or Word Online while you do something else. Trusted keystrokes, real revision entries.
Cadence Sessions
Hand a draft to the cloud and it gets written into your document over hours or days — starting Tuesday evening, finishing Thursday morning, like anyone else would.
The engine
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
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
Calibrated against a public corpus of 136 million keystrokes from 168,000 typists, including how error rates shift with speed.
typo → fix
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
Fluent phrases run fast; sentence and paragraph boundaries collect the long thinking pauses. Nobody types at a constant rate.
Revision preview
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.

Hands-off cloud writing.
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.
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.
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.
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.
