Iro AI

Iro AI teaches people how to actually use AI tools, in five-minute daily lessons structured like a language app. It describes itself as the Duolingo for AI, and the comparison is fair in both directions: the same streak-and-progress loop that makes short daily practice stick, and the same limitation that a gamified app is a habit-builder rather than a deep course.

The distinguishing choice is that lessons are practice rather than video. Instead of watching someone demonstrate a prompt, you write one and the app judges it, or you are shown an AI output and asked to evaluate whether it is any good. The site claims over 3,000 hands-on exercises across 29 guided paths and 477 lessons, organised into six skill zones. Paths are indexed three ways, by tool, by skill, or by job, so you can work through prompt engineering as a topic, or specifically through the workflows relevant to teaching, research, writing or marketing. It covers the major assistants (ChatGPT, Claude, Gemini) and agent workflows rather than tying itself to one vendor.

Judging AI output is the part worth singling out. The common failure mode for a new AI user is not writing a bad prompt, it is accepting a confident wrong answer. An exercise format that puts a student in the position of evaluating rather than just generating is addressing the right skill, and it is the same critical-reading habit good research instruction has always tried to build.

Be clear about the audience. The maker states plainly that this is for adult learners and teachers, not a K-12 curriculum, and that is the right description. We list it for homeschooling parents and educators who want their own AI fluency, and for older high school and college-age students working on practical digital skills. It is not something to hand to a ten year old.

On availability and cost: it runs as an iOS app and as a web app at app.tryiro.com, with Android in development and a waitlist on the home page. It is free to start, with an optional Pro tier at $49.99 a year (seven-day trial on the annual plan) or $9.99 a month. The free tier is enough to judge whether the format suits you, which is the sensible way to approach any streak-based app. Prices are as listed by the maker and may change.
