Yes — AI coding agents (Cursor, GitHub Copilot, Devin) write, debug, and deploy code. They deliver 55% faster development and 30% fewer bugs. But human review is still essential. Here's the full picture.

- Write new code: Build features, APIs, integrations from specifications
- Debug existing code: Find bugs, suggest fixes, explain root causes
- Write tests: Generate unit tests, integration tests, and test data
- Refactor: Clean up code, modernize patterns, improve performance
- Document: Generate README files, inline docs, API documentation
- Code review: Spot security issues, anti-patterns, and edge cases
- Deploy: Some agents (Devin) can create PRs, run CI/CD, and deploy
AI Coding Tools Compared
| Tool | Best For | Cost | Autonomy |
|---|---|---|---|

| Devin | Autonomous coding agent | $500/mo | High (full tasks) |
| Claude Code | CLI coding agent | $20/mo (Claude Pro) | Medium-High |
| ChatGPT | Code generation + explanation | $20/mo | Low (chat only) |
| Aider | Open-source CLI agent | Free (API costs) | Medium |
Productivity Gains
| Metric | Without AI | With AI |
|---|---|---|
| Lines of code/day | 100-200 | 300-500 |
| Time to build a feature | 2-5 days | 0.5-2 days |
| Bug rate | Baseline | 30% fewer |
| Test coverage | 40-60% | 70-90% |
| Onboarding time | 2-4 weeks | 1-2 weeks |
What AI Still Can't Do
- Architecture decisions: Choosing the right system design still needs human judgment
- Understanding business context: AI doesn't know your users, market, or constraints
- Security review: AI can spot common issues but misses novel attack vectors
- Performance optimization: Profiling and optimizing complex systems needs humans
- Legacy code: AI struggles with undocumented, decades-old codebases
Best approach: AI writes 60-80% of the code. Humans review, architect, and handle edge cases. This is now the standard at most tech companies.
