What Code Is AI Writing?

AI Code Autocomplete in IDE
AI coding assistants excel at generating boilerplate code, tests, and standard patterns.

AI excels at boilerplate, tests, API integration, and documentation. Tools like GitHub Copilot, Cursor, and Tabnine are leading this transformation. For full-stack app generation, newer tools like Bolt.new and v0 by Vercel are pushing boundaries even further.

Impact on Developer Roles

Rather than replacing developers, AI tools shift the role toward architecture and review. See our coverage of the broader AI adoption study and the best AI tool stacks for dev teams.
