We present Dripwrito — a server-side writing-cadence instrument that types a user-supplied draft into a Google Document character-by-character, over a duration of 30 minutes to 30 days.
The resulting version history exhibits statistical properties consistent with authentic human authorship: Poisson-distributed pause intervals, QWERTY-adjacent transposition errors, variable burst velocity, and a structured revision pass in the final decile of the session. Documents produced by the instrument pass natural-cadence scoring at a rate of 98.2%. The engine operates entirely on the server; the user's browser may be closed at any point without interrupting the session.
The version-history problem.
Modern document platforms preserve the complete edit timeline of every file. Submission portals and academic integrity systems increasingly examine this history for evidence of authentic, time-distributed composition.
A document produced by pasting a finished draft registers as a single high-velocity insertion event — statistically anomalous, and trivially distinguishable from hours of sustained writing.
Dripwrito resolves this by distributing the composition event across time on a calibrated cadence, producing a version history indistinguishable from authentic drafting behaviour.
Instantly flagged as anomalous by cadence scanners.
Distributed across an entire working day with realistic gaps.
Across 172,431 dripped documents in production.
The instrument, live.
The drip engine computes a cadence schedule at session start — a deterministic sequence of character-insertion events with interleaved pause intervals, typo-and-correction pairs, and velocity fluctuations.
A Vercel Cron worker ticks every 60 seconds, consuming the pre-computed schedule via O(1) lookup and flushing the next batch of characters to your Google Document through the Docs batchUpdate API.
Drop in any essay, paper or cover letter. Up to 50,000 words on Pro. PDF and DOCX upload included.
Choose a duration — 30 minutes to 30 days. Set pause frequency, burst speed, overnight gaps.
The engine runs on the server. Close your browser. You get an email when the session completes.
Trusted across eight institutions.
Four properties of note.
Runs while you sleep.
The drip engine lives on the server — not your browser. Close the tab, turn off the laptop. The document keeps writing.
Passes every audit.
Real pause gaps, QWERTY typos, re-reads, variable burst speed. The session log is forensically consistent with a human author.
Strip the AI tells.
"Delve." "Tapestry." "Cannot be overstated." Dripwrito spots them, rewrites them, and ships a voice that reads like a person.
A certificate for every drip.
