FAQ

Frequently asked questions.

Does Chimmi really work offline?

Yes — 100%. All AI processing happens on your device using Apple's on-device machine learning. You can use Chimmi in airplane mode, on a flight, in a remote cabin, or anywhere else with no internet.

Is my data private?

Completely. Chimmi never uploads your recordings, scans, or notes to any server. There's no account system, no tracking, no analytics. Your data lives on your phone and nowhere else.

Is Chimmi free?

Chimmi is a paid one-time purchase on the App Store. No subscription, no ads, no ongoing fees. Pay once, own it forever.

Which devices does Chimmi support?

Chimmi is available for iPhone on iOS. An Android version is in the works.

Can Chimmi replace my note-taking app?

For many people, yes. Chimmi combines recording, scanning, writing, and AI chat in one app — removing the need for separate transcription, OCR, and AI tools.

How accurate is the transcription and OCR?

Chimmi uses Apple's best-in-class on-device Speech Recognition and Vision frameworks. For clear audio and clean text, accuracy is excellent. Handwriting recognition works best with reasonably legible writing.
