The Verdict
Duolingo is built for language learners and students, with a focus on lessons and stories. GitHub Copilot targets developers and open source contributors and leads with code-completion and chat.
Both tools come in at similar price points ($9.99/mo for Duolingo, $10/mo for GitHub Copilot), so pricing won't make the decision for you.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Both tools are a solid fit for students — in those cases, the decision often comes down to workflow style and how your team prefers to organize work.
This is a genuinely close comparison. If you can, sign up for both free trials (where available) and run a one-week test with your actual team tasks before deciding.
