AI in Android Development at Duolingo
summary
Duolingo describes concrete engineering results: production features like an AI conversation partner and thousands of hours of generated podcast content, org-wide rollout of Codeex for parallel code tasks, and daily developer tooling like Slackbot (GPT), Cursor and Graphite’s Diamond for PR review. Examples include porting a Swift chess engine into a Kotlin Multiplatform library (GPT handles ~100-line chunks, Gemini finishes larger context, added unit tests to prevent regressions), AI-edited JSON for UI hints, Cursor locating a blame PR, and automated Jira triage.
