Typical pairing

IntelliJ users often keep JetBrains AI for in-IDE navigation and use Liminal for cross-repo automation, CI debugging, or research-heavy tasks.

Liminal does not require migrating off JetBrains: it runs beside your existing IDE with its own workspace root.

Enterprise considerations

Both can operate in regulated environments. Liminal keeps inference keys and session logs under your control by default, with optional Pro license for teams.
