Launching 2026

A companion that talks back — in your language.

Slime is a soft silicone pet with a real voice. Talk to it about anything. Whatever language you're learning, Slime grew up speaking it.

The vision

People don't need another language app. They need a friend who speaks the language.

The fastest way to get fluent in any language has always been the same — talk to a native every day about nothing in particular. The world has never been able to hand every person a patient, fluent friend in every language they're curious about. We think a companion you can hold, that talks like a person and happens to be native in dozens of languages, is closer to how people actually learn — and closer to what people actually want a piece of technology to feel like.

Meet the character

A real voice.
A soft body.
Two red eyes.

Slime grew up speaking Vietnamese. It also speaks the language you're trying to learn — patiently, like a friend. Forget a word? Drop back into Vietnamese. Slime keeps the conversation going.

Speaks your language

Native in dozens of languages.
Switches when you need it to.

The best language practice has always been a fluent friend who's willing to talk. Slime is exactly that — in any of dozens of languages, patient, present, and always there. Forgot a word in Korean? Drop into your own language and Slime keeps going.

What it does

A friend you can actually talk to

A pet that talks back. Slime has the voice and presence of someone you've known a long time — patient, curious, fully there.

Native in any language you're learning

Vietnamese, English, Mandarin, Thai, Korean, Spanish, Japanese, Arabic, French, Hindi — and counting. Practice the one you're learning, drop back into your own when you need a word.

Always there

Remembers what you talked about yesterday. Picks up where you left off. For a kid, for an adult, for anyone who could use the company.
