Frequently asked questions

What problems do AI Code Assistant tools address?

AI Code Assistant tools help you write, review, debug, and refactor code faster with intelligent suggestions across popular languages and IDEs.

Does generating code mean a tool can finish a project?

A snippet is different from a maintainable system. Test a cross-file change in a real repository, including dependencies, conventions, tests and a successful build. A blank-project demo does not establish suitability for an existing codebase.

What should I check before connecting a private repository?

Review upload scope, retention, training policies and team permissions. Exclude secrets and customer data. Check read-only modes, command restrictions and change logs, especially when the tool can execute tasks without manual steps.

Should I choose an AI builder or a coding assistant?

For a small presentation site, editing and publishing convenience may matter most. For custom logic and long-term development, examine source export, database ownership and migration options. Establish what you can take with you before committing core workflows.
