Frequently asked questions
What is the best AI tool for developers?
For in-editor work, Cursor, GitHub Copilot, and Windsurf are widely adopted. For technical Q&A with citations, Phind and Perplexity are popular. Many developers combine an IDE assistant with a general chatbot.
Are AI coding tools safe for company code?
Policies differ by vendor. Review whether code is sent to the cloud, stored for training, and whether enterprise tiers offer zero-retention or self-hosted options before using on private repositories.
Can AI replace senior developers?
AI accelerates routine coding and exploration, but architecture decisions, security review, and production ownership still require experienced engineers. Treat suggestions as drafts to verify.
What free AI tools do developers use?
Codeium, Continue.dev, HuggingChat, ChatGPT, and Claude offer usable free tiers. GitHub Copilot is free for verified students and some open-source maintainers.
