MT Intelligence
QuillBot is a real, established business founded in 2017 at the University of Illinois and now part of Learneo, Inc., a major education-technology company. Our antivirus network and browser blocklists show no malicious flags, and the domain has valid SSL and clean hosting reputation. The site ranks in the global top-100k by traffic, consistent with a major productivity platform. However, the evidence package reveals 29 complaints filed with the Better Business Bureau over three years, primarily about billing, subscription cancellations, and customer-service responsiveness. Independent review aggregators show strong positive ratings (an independent review aggregator, Capterra, G2) praising the paraphrasing and grammar-checking features, but criticism centers on support quality rather than fraud or scam activity. The page's reference to OpenAI/ChatGPT appears to be generic marketing language, not impersonation. No scam families or credential-harvesting patterns were detected.

Still, stay alert
No major threat indicators — but a clean scan does not guarantee every page is safe, and phishing emails routinely spoof real domains.
- Double-check the exact URL in your address bar
Confirm you are actually on quillbot.com and not a lookalike like q-uillbot.com.com or an IDN homoglyph.
- Use a password manager
Password managers only auto-fill on the exact domain they were saved for — they refuse to fill lookalike domains, which is the single best phishing defence.
