The Learning Engine

Most apps are designed to keep you scrolling. Bubbles is designed to make you stop, think, and remember.

1

Read in 60 seconds

We distill complex topics into their absolute core. No fluff, just the "Aha!" moment, written to be understood instantly.

2

Test to Remember

Passive reading is forgotten in minutes. Every Bubble ends with a quick check that forces your brain to encode the information.

3

Connect Forever

Ideas aren't isolated. As you learn, Bubbles links concepts together, building a "latticework" of mental models in your mind.

Summaries create the 'Illusion of Competence'—you feel like you know it, but you can't use it. Bubbles uses Socratic dialogue and quick checks to force your brain to actually handle the information, which is the only way to build permanent retention.

I'm already overwhelmed with content. Why should I add another feed? expand_more

Bubbles isn't more noise; it's a filter. Most people use it for 10 minutes a day to replace mindless scrolling with high-resolution insights. It’s designed for high-impact, low-friction learning that fits into the gaps of your day.

What do the 'Simulated Voices' actually do for my learning? expand_more

They aren't just for show. Each voice (like a Stoic, a Scientist, or a Strategist) provides a different 'lens' on the same idea. By hearing how different perspectives apply a principle, your brain builds a more complex mental model that’s easier to recall in real-life situations.

Can I really learn a complex subject in 10 minutes? expand_more

The brain learns better through frequent, short exposures than through long marathons. We break complex topics into 'atomized insights.' You master one small piece, test it immediately, and stack it onto the next. Frequency beats intensity every time.

Is my data private? I'm tired of being tracked. expand_more

Completely. Bubbles is a private ecosystem. No public profiles, no 'likes' for clout, and no social pressure. It's just you, the ideas, and your future self. Your learning journey is yours alone.

Do I have to commit to a long-term subscription? expand_more

Not at all. We offer a free tier to get you started. If you choose to upgrade to Core or Elite for more interactions, you can cancel anytime through the App Store with one tap. No hidden fees or dark patterns.
