Overview

Duolingo's "AI-First" Controversy refers to a viral debate and controversy surrounding the language-learning educational application Duolingo, whose cofounder and CEO, Luis von Ahn, announced via email in late April 2025 that "Duolingo is going to be AI-first" and will “gradually stop using contractors to do work that AI can handle.” The news was posted on LinkedIn and quickly sparked negative reactions from users of the language-learning app, who started a "mass unfollowing" campaign against the company's pro-Artificial Intelligence approach, as well as sharing memes and jokes "cancelling" the app.

Background

On April 28th, 2025, Duolingo^[1] shared an all-hands email from their CEO, Luis von Ahn, claiming they're "going to be AI-first," meaning the company will rethink its current business model to focus on Artificial Intelligence projects and features, such as "gradually stop using contractors to do work AI can handle." The email reiterates, "Duolingo will remain a company that cares deeply about its employees" and that AI is not replacing the workers, but "removing bottlenecks so we can do more with outstanding Duos [staff] we already have." The message was posted on Duolingo's LinkedIn (seen below), amassing over 4,800 likes and 589 reposts in a week.
