Three reasons people switch.

Reflect is the AI-first, privacy-by-default diary — and the only one that speaks Korean, Arabic, Japanese, and Hindi as first-class languages.

01

AI that's actually useful.

Voice transcription. Paper-diary OCR. Happiness patterns. MBTI from how you write. A Yearly Narrative that reads like a letter from yourself.

02

Encrypted before it leaves your phone.

AES-256-GCM with tamper detection by default. Recovery-code-derived key. Zero-knowledge cloud. Most "private" apps are plaintext SQLite — security theater.

03

First-class in your language.

10 languages, all built-in: EN, FR, ES, IT, PT, DE, AR with full RTL, KO, JA, HI. Crisis lexicon reviewed by native speakers in AR/KO/JA/HI.

Frequently asked.

What is Reflect Diary?

Reflect Diary is a private AI diary app for iPhone and Android. It transcribes your voice into entries, scans handwritten pages from paper journals with OCR, tracks mood, and surfaces patterns in your writing — all encrypted with AES-256-GCM on your device. Cloud backup is zero-knowledge, meaning the encryption key derives from a recovery code on your phone, so even Reflect cannot read your entries. Available free in 10 languages including English, Korean, Japanese, Arabic with full right-to-left layout, and Hindi.

Is Reflect Diary really private?

Yes. Every entry is encrypted with AES-256-GCM and HMAC tamper detection by default, not as an opt-in. The encryption key is derived from a recovery code that never leaves your device unencrypted, so even Reflect can't read your diary. Add a biometric, PIN, or password lock and only you can open the app.

Does Reflect work without an account?

Yes. Journaling, mood tracking, and most features work fully offline with everything stored locally on your device. An account is optional and only needed if you want encrypted cloud backup or zero-knowledge cross-device restore.

Which languages does Reflect support?

Ten languages with native-quality translations: English, French, Spanish, Italian, Portuguese, German, Arabic (with full right-to-left layout), Korean, Japanese, and Hindi. The crisis-support lexicon was reviewed by native speakers in Arabic, Korean, Japanese, and Hindi.

Is Reflect free?

Core journaling, mood tracking, themes, photo and voice memo attachments, and the lock screen are free forever. AI features have a generous free monthly allowance; premium unlocks unlimited transcription, insights, and the deeper analyses like MBTI and the Yearly AI narrative.

Can I import my old paper diary?

Yes. Photograph any handwritten or typed page and Reflect's OCR extracts the text, detects the date written on the page, and tags the mood automatically. It's the fastest way to digitize years of handwritten journaling.

Does Reflect work on iPad and Apple Watch?

Yes. iPad has an optimized layout that takes advantage of the larger screen, and there's a watchOS companion for quick mood logging from your wrist. Entries sync across devices when encrypted cloud backup is enabled.
