For Codex and Claude Code

Ship better Java with your coding agent.

JAIPilot connects to Codex or Claude Code and helps your coding agent write, improve, and optimize Java code. It adds Java-specific workflows, verification, and remote execution to the agent you already use.

Run the slow stuff elsewhere.

When a Java build, test suite, analyzer, profiler, or benchmark is too heavy for your laptop, your agent can move it to a private disposable workspace. You approve the upload first.

JAIPilot returns status and logs. It does not commit, push, open a PR, merge, or silently copy remote edits back.
