Having a variety of interactive types (flashcards, fill-in-the-blanks, quizzes, etc.) keeps learning sessions engaging.
Gives you an alternative to:
Play through your interactive lessons daily and build a streak.
Use the built-in spaced repetition system to automate your learning.

Gives you an alternative to:
If there's something you've always wanted to learn, this is what practicing it looks like.

Interact is a genuinely unique product built from scratch to solve a seemingly simple problem: How do we connect what we're learning to what we want to do?
Anki is the original for spaced repetition, but only has "Decks" to structure your learning. There's no system to track progress on your actual learning goals.
Quizlet gives you great tools to study for a test. But what if you actually want to learn the material, and not just pass a test?
Online courses give you a predefined curriculum that doesn't adapt to what you're trying to learn. For niche topics, your best bet is to build your own curriculum.
To my knowledge, there are no other tools out there that integrate all these pieces together. You can build your own curriculum that evolves as you learn. You can make real progress on your actual learning goals. You can tame the overwhelming amount of content by extracting only the parts that matter. And instead of an arduous chore, it's all designed to be a joy to use.
Here's some of what shipped in September and August 2026.
Completely redesigned the Create page.
Renamed Interactive Mode to Ask, and gave it a lot more to do. It started out as a way to ask questions about your learning data. Now it can create and update subjects, goals, resources, lessons, and notes, so you can change almost anything by typing a sentence instead of clicking through screens. It will also answer a general question about a topic and offer to build interactives from the answer.
Integrated math syntax into the generator features. Generated lessons can now include LaTeX equations, which works well for math and physics subjects. Code snippets come through with syntax highlighting too.
Launched v0.3 of the native apps with major usability improvements and bug fixes for interactive lessons.
Interact is live on the App Store! After the soft launch, the native apps are approved and available to everyone. Download Interact on the App Store for iPhone, iPad, Apple TV, and Apple Watch.
