Predictive AI

FUN Keyboard is an iPhone keyboard built to make typing faster, simpler and more fun. Resize it to fit your hands, get useful predictions and automatic punctuation, access emojis and stickers without interrupting what you’re writing, and use a built-in scientific calculator right from the keyboard. It also adapts automatically across English, Spanish, French, German and Italian, including the keyboard layout itself.

Hey Product Hunt 👋 We built FUN Keyboard because typing is one of the things we do most on an iPhone, yet it still often feels more frustrating than it should. Our goal was simple: make typing faster, more comfortable and more fun. FUN Keyboard includes resizable layouts, useful predictions, automatic punctuation, quick emoji and sticker access, automatic switching between five languages, and even a built-in scientific calculator. We’re still improving it constantly, so I’d especially love feedback on one thing: What would make you replace your current iPhone keyboard? If you try it, let us know what feels great and what still needs work. Type fast. Have fun!

Ultra Privacy and Full Access in FUN Keyboard

FUN Keyboard does not collect, store or transmit anything you type. Predictions and preferences are processed locally on your device.

Apple requires third-party keyboards to have Allow Full Access enabled to copy and paste sticker images. This is an iOS requirement for using the clipboard, it is not permission for FUN Keyboard to read or collect your typing.

NanoLM: word prediction as low-energy bonding

FUN Keyboard uses NanoLM, a deterministic on-device language architecture built around a simple idea:

Words that naturally belong together should require less computation to connect.

Think of each word as an atom. Context creates an energy field around it and likely next words occupy the lowest-energy orbitals. Like atoms forming a stable molecule, the most natural continuation should fall into place without searching a huge probability space.
