CHALLENGE
The challenge was to deliver a seamless Grammarly experience for Android users, ensuring flawless functionality and real-time AI-powered writing assistance across all devices and integrations. We’d need to…
Upgrade the app and keyboard to work for every user.
Help enable a next-level, AI-powered writing assistant just as phenomenal as the desktop and browser versions, no holds barred.
Large language models for Rewrites Engine can be resource-intensive, potentially causing performance issues or crashes on mobile devices.
Data quality and old Analytics server don’t satisfy growing product and business needs.
