AI-first code editor with whole-codebase context, multi-file edits and agent workflows.
What it is good at
Codebase-wide indexing means it reasons about a multi-file project rather than the open buffer, which is closer to what a software-engineering student actually faces. The agent's diff view makes every proposed change reviewable line by line, which is pedagogically useful.
Use it for
Handing students a small legacy repo with no tests and having them generate a test suite, then grading the coverage gaps the AI missed. Running a live refactoring demo and having students predict which call sites break before accepting the diff. Comparing two students solving the same problem with and without it, then testing who can explain the result a week later.
Where it falls short
The free-Pro-year student program was discontinued for new signups in June 2026, so do not build a course around it. At $20/month it is a real cost to a community college student and requiring it raises equity issues a free-tier alternative avoids. Its agent will confidently restructure code in ways that pass tests but violate the assignment's learning objective, and beginners will not notice.

Computer Science: Good for teaching code review at project scale — but the student discount is gone.
