Many developers report that Gemini Code Assist speeds up environment setup by 55% and increases unit test coverage by 48%. You’ll also want to check if the tool supports collaboration if you work in a team.

Security and Privacy

Security matters, especially if you handle sensitive code. Some companies ban AI tools because they worry about sending proprietary code to third-party servers. Tools like Tabnine and Qodo offer local deployment or strong privacy controls. Studies show that AI-generated code can sometimes introduce security flaws, so you should always review suggestions before using them. Hewlett Packard Enterprise used an AI assistant to automate code reviews, which helped catch issues early and improved code quality.

Cost and Value

You should weigh the cost against the features you need. Prices range from free open-source options to enterprise plans. Faster development can save you money in the long run, with companies reporting shorter release cycles and higher ROI. Most tools offer a free trial or limited free tier, so you can test them before making a commitment.

You have a lot of great AI programming assistants to choose from. If you’re just starting out, try Figstack or ChatGPT for clear code explanations. Professionals often pick GitHub Copilot or Tabnine for speed and privacy. Teams love Qodo and Replit AI for collaboration.
