How it works
Three steps. That's it.
Upload your document
Upload your .docx file and WriteSim extracts the text, preserves the formatting, headers, footnotes, and images — then creates a matching document on your OneDrive.
Pick a duration
Choose how long the writing should take — 30 minutes to 7 days. Longer sessions include realistic overnight pauses.
Watch it appear
WriteSim gradually types your text with natural pacing, random pauses, and realistic breaks. Your version history builds itself while you do literally anything else.
Everything you need
Simple, powerful, and designed to stay out of your way.
Natural version history
Edits appear gradually over hours or days, creating a realistic writing timeline that holds up to scrutiny.
Full format preservation
Upload a formatted document and WriteSim preserves everything — headers, footnotes, bold text, images, and page layout.
Smart overnight pauses
Sessions over 24 hours automatically pause between 11pm and 6:30am. Because no one writes an essay at 3am.
Background processing
Close your laptop, go to class, take a nap. WriteSim runs on our servers and keeps working while you're away.
Footnote support
Academic documents with footnotes, endnotes, and citations are fully supported. Superscript references transfer perfectly.
OneDrive integration
Connects securely to your Microsoft account. Only accesses the document you choose — nothing else.
Your text, untouched
WriteSim never rewrites, edits, or paraphrases your content. Your exact words go in, exactly as you wrote them.
Pause & resume
Full control over your session. Pause mid-simulation and resume exactly where you left off.
