Iro AIIro AI Blog
Headway and Blinkist do the same job: a book, compressed, in about fifteen minutes. If you are looking for an alternative, the useful question is whether you want a better version of that job or a different job entirely.
Editorial note: Iro AI is our app. Where it appears below we say so, and it has to earn its spot by the same criteria as everything else.
Blinkist if you want the same thing done differently. Something else entirely if summaries have stopped working for you. Those two apps are close substitutes, and choosing between them is a question of interface, library and price rather than approach.
The more useful fork is the second one. If you have a shelf of finished summaries and nothing about your week has changed, the answer is not a third summary app. It is a product where the session is a thing you do rather than a thing you read.
Three reasons, in roughly the order they come up.
Iro AI turns ideas like the ones in this post into 5-minute exercises with feedback. Free tier, Pro from $4.17 a month ($49.99 a year, 7-day free trial).
Grouped by job. The first row is a like-for-like swap; the rest are different products for a different goal.

About the blank cells. Anything marked "not verified by us" is something we could not confirm from the company's own store listing or website at the time of writing. Most comparison pages fill those cells from affiliate sites, which is how a wrong price ends up repeated on twenty pages. We would rather leave a gap and send you to the listing. Check the renewal price and the cancel path before you enter a card, on any app here, including ours.
Iro is the alternative if the summaries you kept opening were about AI. The daily commitment is the same five minutes. What changes is what happens inside it: you write a prompt and get told which part was weak, you spot the fabricated citation in an otherwise plausible answer, you pick between two tools and learn why one loses.
It is a curriculum rather than a library: 29 paths across ChatGPT, Claude, Gemini, Perplexity, prompt engineering, agents and automation, 3,000+ exercises across 24 exercise types, with streaks and 16 ranks doing the same habit work that keeps people opening a summary app.
Iro also runs as a free web app at app.tryiro.com with no signup, which is the quickest way to find out whether the format fits.
Ask what you want to be true in a month.
If it is "I will have read about twenty more things," a summary app delivers that reliably and you should pick on library and interface. If it is "I will do one specific thing better," you need a product built around repetition and feedback, and you should pick the one that specialises in that thing.
Then check the free tier properly. Not whether it exists, but whether it lets you do the real activity. A free tier that only shows you a tour tells you nothing about whether you will still be using the app in March.

Blinkist is the closest like-for-like swap, since both compress books into short summaries. If the reason you are leaving is that summaries have not changed anything you do, the better answer is a practice-based app in whatever skill you care about: Iro AI for using AI tools well, Brilliant or Khan Academy for maths and science foundations.
They do the same job, so the honest answer is that it comes down to library, interface and current pricing rather than approach. Sample both. If neither is producing a change in what you actually do, the choice between them is not the decision that matters.
Khan Academy is entirely free. Iro AI is free to start on iOS with every path open, paced by a Battery that gives you a lesson a day and recharges overnight, and it runs as a free web app at app.tryiro.com with no signup. Compare what each free tier lets you actually do, since the word covers very different things in this category.
Because a summary transfers an argument, and arguments do not become habits by themselves. The format is optimised for coverage: it gets you the shape of a book in fifteen minutes. Building a skill needs repetition with feedback, which is a different activity and a different kind of product. Finishing lots of summaries and changing nothing is the format working exactly as designed.
Only in session length. Both ask about five minutes a day. Headway gives you a compressed book; Iro gives you an exercise with instant feedback, across 29 curated paths about using AI tools. If your goal is broad reading through professionally condensed books, Headway is the better fit. Iro is not confined to AI — Custom Paths (a Pro feature) generate a path on any topic you name, from a typed subject, a link, a screenshot or a PDF — but it is a practice product, not a reading library.
