Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on custom models trained on private code, and can be personalized to a team's codebase caught me off guard. still, I'd recommend giving it a real trial.

Does the job

Pretty happy overall. Automated test and documentation generation just works and strong privacy and security controls. Suggestion quality varies by language can be annoying, but no dealbreakers — I'd recommend it to a friend without hesitating.

Solid for our team

We rolled this out across the team last quarter and supports self-hosted and air-gapped deployments. Custom models trained on private code fits neatly into how we already work, and context-aware code completions removed a step we used to do by hand. Enterprise setup can be complex, which is the main caveat, but it has held up under daily use.
