The Jina Difference
Jina executes your code in a long-horizon QA harness, using a context graph to find deep runtime issues static review misses.
Jina learns how your code, infrastructure, and past issues fit together. That context guides every investigation.
On every PR, Jina combines its understanding of your system with the code change to plan critical production scenarios, including the ones most likely to expose a bug.
Jina gives each scenario to its own investigation agent and shell. This swarm of agents simulates the scenarios, runs the code, probes the system, and reports its findings.
Jina learns from each result. Those results flow back into the planner, which creates new scenarios to investigate deeper issues.
Jina groups related findings, removes noise, and returns the issues that matter with a merge score for the PR.
