Verdict
Pick Junie if you work in IntelliJ IDEA, PyCharm or another JetBrains IDE and want an agent built by the same company. Its Plan Mode writes editable plans you can commit, Live Prompting lets you steer it mid-task, and it runs the same way in the IDE, the CLI and CI. With your own API keys or a local model, JetBrains charges nothing at all.
Pick Copilot if you want inline completions and an agent across every editor your team uses, or you work on GitHub. Pro at $10 includes unlimited completions and 1,500 credits, worth more than Junie’s 10 credits at the same price, plus a cloud agent that turns issues into pull requests.
On value, Copilot’s included allowance goes further for most people. Junie wins if you bring your own keys, since there’s no markup, or if Junie Lite’s free model covers your routine work.
On privacy, check your settings either way. Copilot’s individual plans now train on your interactions by default unless you opt out. JetBrains says detailed collection is off by default, but its legal FAQ says it’s on for non-commercial licences.
