Creative writing, trivia, automation, private questions, planning and more — completely offline. Nothing you type is ever sent to a server, logged, or used to train anything.
// What can it do?
Use cases are labeled by which AI tier first supports them. If your device has a higher tier, it handles everything below it too.
Every message you send a cloud AI is logged, may be reviewed, and in many cases feeds future training. That includes symptoms you described, finances you shared, and personal situations you explained. With Mulberry, nothing leaves your phone — not the embarrassing questions, not the sensitive ones, not the ones you'd delete if you could. The sixth category below exists because of this.

Tap any prompt to copy it. Gold prompts are ones most people would never type into a cloud AI.
Mulberry's on-device AI handles creative writing, trivia, automation scripting, and everyday tasks — completely privately, with nothing sent to any server.
