Description of app.grammarly.com
app.grammarly.com appears to be the web application and landing area for Grammarly, an online writing-assistance platform. Based on the page title, metadata, and screenshot, the site offers AI-assisted writing tools such as grammar correction, proofreading, tone suggestions, and text refinement for users working across apps and websites.
The branding, navigation, and linked assets indicate that this subdomain is part of Grammarly's broader service infrastructure rather than an unrelated third-party site. The page includes account sign-up and login options, product navigation for work and education use cases, and references to browser-extension distribution, which is consistent with a software-as-a-service platform focused on writing productivity and communication support.
Safety Assessment for app.grammarly.com
At the time of this scan, no security engines reported detections for this domain, with 0 out of 89 engines flagging it. The malware scan also indicated a clean result, with 0 flagged files out of 8 scanned, and the reviewed external links, referenced domains, and iframe checks did not show flagged items. In addition, multiple blacklist and threat-database checks were reported as clean at the time of analysis.
Other contextual signals are also favorable. The domain has been registered for many years, the page content matches the expected Grammarly branding and functionality, and the screenshot shows a polished product page rather than patterns commonly associated with phishing, malware delivery, or deceptive storefronts. Based on available data, no threats were detected at the time of this scan.
As with any point-in-time assessment, this reflects the observed state during scanning rather than a permanent guarantee. Based on available scan data, no significant threats were detected at the time of this scan.
Technical Description
The site presented a valid SSL/TLS certificate issued through Amazon infrastructure, with certificate validity extending to 2027-01-31. It resolves to an AWS EC2 address in us-east-1 (Ashburn, United States), and the nameserver set uses AWS DNS services, which is consistent with a large cloud-hosted web application deployment.
DNSSEC appears to be unsigned, which is not uncommon but means DNS responses do not benefit from DNSSEC validation. No immediate technical security concerns were evident from the provided scan data: blacklist checks were clean, no malicious files were flagged, and the linked resources appear to come from Grammarly-controlled or mainstream third-party domains.
