Heyo Product Hunt 👋

I'm Kevin, co-founder/GTM of Gravity 💫

We're a team of polyglots and language learners who've lived abroad, gotten lost in foreign places, and watched friends, family, classmates, and ourselves hit the same wall: applied language learning is still an unsolved problem. You can grind apps and textbooks for months and still freeze ordering from a menu, because the vocabulary you study rarely matches the words actually in front of you.

Gravity started from a simple belief: language learning should follow you into real life, and feel effortless enough that your only job is _learning_—not working through lessons, drills, and word lists that have nothing to do with what you actually see.

So we built the app to absorb the world around you. Snap a photo of a menu, a sign, a manga panel, a subtitle, a screenshot, a friend's text—and Gravity pulls the Japanese out of it and turns it into context-based flashcards and a daily plan built around your life. The smart review system surfaces the most useful, most frequently encountered words first. And the more Japanese you run into, the sharper it gets.

It's four steps:

1. Snap a photo or screenshot of Japanese text
2. Tap the words you want to learn
3. Gravity builds personalized flashcards + a daily plan automatically
4. Review a little each day, watch it stick

(P.S. We're starting with Japanese—the language that made us fall in love with this problem in the first place.)

For the lazy person, it's a lifesaver. Point your camera at something, and we flawlessly extract the language behind it and fold it straight into your plan. No setup, no decks to build, no overwhelming backlog of cards you'll never finish.

For the power user, it's also a lifesaver. The desktop/web language-acquisition ecosystem—sentence mining, SRS, the whole pipeline—is powerful but brutal to set up, and that friction scares off most people before they start. Meanwhile the mobile side has always lagged behind. We're closing that gap.

Whether you're an immigrant, expat, exchange student, or just deep in anime, manga, and J-pop—Gravity meets you where you already are.

Our mission is to help more of the world become fluent in the language around them. Not just textbook fluency, but the confidence to read the menu, follow the sign, understand the message, and feel at home in a place that once felt unfamiliar.
