JetBrains Doesn’t Want Me To Give This Talk

Talkat JetBrains JavaScript Day 2025 · on Thursday, 2025-10-02· [developer-experience, open-source]
slides:none on file

Explains why JetBrains balances AI work with IDE reliability, lists actual tools and timelines: an AI assistant, agentic tooling Juny, and a new web coding product Kinetto are live or in trials; the team runs AB tests on a homegrown Type Engine with a plan toward 2025.3 for TypeScript. Shares concrete metrics: an Appex perf threshold of ~300ms tolerable vs 500ms frustrating, monitors regressions (2024.1 → 2024.2 rollback), and reports fixing thousands of bugs while shipping ~200 features.
