Frequently Asked Questions
Are AI coding assistants safe to use at work?
It depends on your employer's policy. For sensitive codebases, look at Tabnine, which can run locally or on-prem so your code never leaves your environment. Always check your company's rules before enabling any assistant.
Can AI coding tools write an entire program?
Agentic tools like Cursor and Replit's agent can scaffold working apps from a prompt, but they still need a developer to review, debug, and guide them. Treat the output as a fast starting point, not a finished product.
Which AI coding tool is best for beginners?
Replit AI is the easiest to start with because it needs no local setup, and GitHub Copilot's chat is great for explaining code as you learn. Both have free options for beginners.
Is GitHub Copilot free?
Copilot has a free tier with monthly limits, and it's free for verified students and maintainers of popular open-source projects. Heavier use needs a paid plan starting around $10/month.
