AI Journal Pro – Daily Diary

AI Journal Pro is your private AI journal: a voice-powered daily diary with smart writing support. Speak or type your thoughts, and the AI cleans up your text, suggests titles and tags, and delivers a personal recap every week, month, and year.

FEATURES

Voice dictation in two modes: on-device speech-to-text (always free) and audio-direct transcription via AI.

Text mode with "Correct with AI": type your entry and let the AI polish it without changing the meaning.

Mood tracking: three levels, one tap. Colour-coded markers in the calendar and a local seven-day mood trend chart.

Recaps that come to you: a compact weekly insight, a full monthly recap with statistics, themes, highlights and suggestions, and a Year in Review.

AI title and tag suggestions: let fitting titles and keywords be generated automatically.

Markdown editor with a formatting toolbar, interactive checklists and photo attachments from camera or gallery.

Timeline with full-text search and filters by mood, tag and starred entries. Calendar month view with mood-coloured day markers. Writing streak with one day of grace.

STORAGE YOUR WAY

Choose where your data lives: local on the device (the default) or in your Google Drive. In local mode your journal never leaves the device.

AES-256 encryption on every backend, local included. The key stays with you, in your own cloud account. Biometric lock and a backup PIN secure access.

Export everything at any time, for free: entries, moods, tags, metadata and photos as Markdown and JSON in a ZIP.

Works offline. Reading and writing always work; AI jobs queue up and run automatically as soon as you are back online.

FLEXIBLE AI

Subscription: all AI features, no setup. We host the AI for you, you just write.

Bring your own key (BYOK): add your own OpenRouter API key once, choose your model, and pay your provider directly.

Try the AI features for free before you buy.

AI cost tracker: keep an eye on your AI usage and spending at any time.

ALWAYS FREE

Writing entries, the calendar, search, photos, on-device dictation, export, the daily reminder and the biometric lock are free, permanently.

PRIVACY

The AI is an analyst, not a chatbot. It never writes entries for you, never asks you questions, and never starts a conversation.

Audio is processed only briefly for transcription and is never stored permanently. We do not train on your text and we do not sell data.

Your entries are strictly private. There are no social features, no sharing with other users, and no ads. You can delete your account, including all of its data, from inside the app.

WHO IT IS FOR

Anyone building a daily journaling habit: a gratitude journal in the evening, a quick mood diary on the commute, or voice journaling instead of typing. If you want a journal app that keeps your words yours, this is it.

Available in English and German. Sign in with Google or email.
