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 building lessons, drills, and word lists that rarely match what you actually see in real life.
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.
We're a team of polyglots and lifelong language learners who have lived abroad, moved through different cultures, and watched friends, family, and classmates run into the same wall. We hope Aio will help make that wall feel a little easier to climb.
Meet the teamMost of us have stitched together our own setup: a streak app, a dictionary, a deck, an AI chat. Here is how those stack up against doing it in one place.

How to immerse, what to watch and listen to at your level, and which apps are worth your time.
How to Learn Japanese Through Immersion (A Realistic Guide)Immersion isn't just watching anime with subtitles and hoping you'll absorb something. Here's how to actually immerse in Japanese without spending 10+ hours a day pretending you're in Japan.
The Best Apps to Learn Japanese in 2026 (By What You Actually Need)There's no single best app for Japanese. Here's an honest breakdown of Airlearn, WaniKani, Anki, Migaku, and more, organized by what each one is actually for.
How to learn Japanese with anime (and actually remember the words)Anime can teach you a lot of Japanese. Bingeing it with English subtitles mostly won't. What I'd watch, how I'd watch it, and the tools that make words stick.
The best Japanese podcasts for beginners, by levelTen Japanese podcasts I'd put on your phone, sorted from first-month beginner to upper intermediate, with what each one is like and who it suits.
The best Japanese YouTube channels for learners, sorted by levelMy picks for Japanese listening practice on YouTube, from slow beginner videos to native vloggers, who each channel suits, and how to get more out of it.
Sentence Mining: What It Is and Why It Beats Your TextbookTurns out that sentence mining accidentally aligns with a lot of research on memory and language acquisition.Comparing apps?

Japanese and Mandarin Chinese. You pick one when you set up, and you can add or switch to the other any time from Home or Settings.
The Media catalog includes more than 1,000 hours of native Japanese video, organised by topic and JLPT level. Moments gives you a shorter, swipeable way to learn from the same kind of real content.
The transcript follows playback word by word. Tap a Japanese word to inspect it, open its dictionary entry, get a contextual explanation, or save it for Study.
Words you choose to save appear in All words. You can practise them there, search and sort them, or organise them into your own decks. Words saved from Media keep their source context so you can return to the moment where you found them.
That’s Aio, your language friend from space. Aio guides you through setup and appears around Gravity as you learn.
