Google Docs Add-on
Thesis checks
that actually help.
Paperly lives inside Google Docs. Formatting checks run automatically. AI rubric review and plagiarism scanning are one click away — no context switching.
Three tools, one sidebar
Live Formatting Checks
FreeRuns every 3 seconds. Flags double spaces, informal contractions, consecutive duplicate words, sentences over 60 words, inconsistent fonts, line spacing issues, and missing required sections — highlighted directly in your doc.
Auto-fix available for double spaces and duplicate words. No credits required.
AI Rubric Check
CreditsPaste your adviser's criteria, one per line. Click Check with AI — Claude reads your full document and returns ✅ Met, ⚠️ Partially Met, or ❌ Not Met for each criterion, with a quoted excerpt from your document as evidence.
1 credit per run.
Plagiarism Scan
CreditsChecks your document against OpenAlex, CrossRef, and arXiv — 250M+ published academic works. Returns similarity scores per paragraph, colour-coded by severity, with source links. Paraphrase flagged text with AI directly in the sidebar.
Checks public academic databases, not unpublished student papers. 1 credit per run.
Who it's for
Final-year undergrads
Submitting a thesis for the first time. Paperly flags formatting issues before your supervisor does.
Postgrad students
Writing longer, more complex documents. AI rubric checks make sure you've addressed every criterion.
Students in developing countries
Turnitin is too expensive or unavailable. Paperly checks against 250M+ public academic works at a fraction of the cost.
Why Paperly
Zero context switching
Works directly inside Google Docs. Open the sidebar via Extensions → Paperly → Open Paperly and everything runs in place.
Pay per run, not per month
Credits never expire. Run checks when you need them — not on a subscription clock that pressures you to justify a monthly fee.
Honest about its limits
Plagiarism checks run against 250M+ public academic papers. They do not check unpublished student work. We say so clearly.
Cheaper than the alternatives
More focused and more affordable than Turnitin, Paperpal, or Grammarly. Purpose-built for thesis students, not general writing.
Pricing
Simple credits, no subscription.
Formatting checks are always free — they run client-side in your sidebar. AI Rubric Check and Plagiarism Scan each cost 1 credit per run. Credits never expire, so you buy what you need and use them on your schedule.
