## What is Ducky?

Ducky is a private, on-device thinking partner. Bring it a problem, a decision, or a half-formed idea, and instead of handing you an answer, it asks the questions that help you reach your own conclusions.

IT'S RUBBER-DUCK THINKING
Programmers have long debugged problems by explaining them out loud to a rubber duck. The Feynman technique and the Socratic method run on the same idea: you think best when you have to put things into words and answer good questions. Ducky is that rubber duck, except it asks questions to keep you going.

HOW IT WORKS
• Say what you're working through, in your own words.
• Ducky asks focused, open questions, one at a time.
• Stuck? Tap the lightbulb for one gentle suggestion, then it goes back to asking.
• Find any past conversation, saved and searchable.
• Export a clean summary to Notes, Mail, or wherever you like.

PRIVATE BY DESIGN
Everything runs on your iPhone with Apple Intelligence. No accounts, no cloud, no analytics, no tracking. Ducky doesn't connect to the internet, so it even works in airplane mode. Your conversations stay on your device, and the only thing that ever leaves is a summary you choose to export. Data collection: none, in every App Store category.

ONE PURCHASE, NO SUBSCRIPTION
Try Ducky free for 3 days. If it fits how you think, a single one-time purchase unlocks it for good. No subscription, no recurring charge.

HONEST ABOUT AI
Ducky is an AI, and a bit of a bird-brain. Treat anything it suggests as food for thought, never advice. Your judgment is what matters, and Ducky will never stand in for professional guidance.

REQUIREMENTS
Ducky needs an iPhone with Apple Intelligence: iPhone 15 Pro, iPhone 15 Pro Max, or iPhone 16 or later.

• Now available in 16 languages — Ducky's interface is fully localized, so you can think out loud in the language that fits you best.
• A better rating experience — we refined when and how Ducky asks for a rating, so it's easy to share how your thinking's going, and just as easy to skip when you'd rather not.

As always, everything stays on your device: no accounts, no cloud, no tracking.
