AI Journaling App

The AI journaling app that never reads your journal.

Most AI journaling apps power their "AI" features by sending your entries to a cloud service. This one doesn't — the AI companion runs entirely on your own device, and your words never leave it.

How most AI journaling apps actually work

To summarize your entries, discuss your patterns, or help write your story, an AI needs to read what you wrote. The common way apps deliver that feature is by sending your entry text to a cloud AI provider's servers each time you use it — which means a copy of your private writing passes through a company you've never heard of, every time.

The common approach

  • Your entry text is sent to a cloud AI provider to generate a response
  • The company can see what you wrote, at least in transit
  • Requires an internet connection to use AI features at all
  • Your data may be used to improve someone else's model

Encrypted Diary

  • The AI companion runs locally on your own computer, via Ollama
  • Your entries never leave your device — not even to power the AI
  • Works fully offline, AI included
  • Nothing you write is ever used to train anything

What the Companion actually does

01

Discusses your entries

Ask what you were worried about last fall, or what patterns it notices in your own writing — answered by a model running on your machine, not a server.

02

Interview Mode

56 guided questions across 7 chapters — Beginnings, The People, Turning Points, Work & Craft, Love, What You Know Now, Legacy — for the days you don't know what to write.

03

Writes your Life Story

When you're ready, compile everything you've answered into a printable, PDF-ready narrative — a memoir assembled from the life you've already recorded.

04

Voice, transcribed locally

Speak your entries; transcription happens on-device, never sent anywhere to be processed.

"If we had to read your journal to make the AI work, we would have built a different product."

Own it, no subscription required

One license, $79, once. The journal and the AI companion both work forever — no ongoing cost required. An optional $29/yr adds software updates and encrypted cloud backup, if you want them.

Common questions

What is an AI journaling app?

An AI journaling app is a journal or diary application that uses artificial intelligence to help with writing — discussing your entries, summarizing patterns over time, suggesting reflection prompts, or compiling your entries into a life story. Most AI journaling apps send your entry text to a cloud AI provider to power these features.

Is there an AI journaling app that keeps my entries private?

Yes. Encrypted Diary's AI companion runs entirely on your own device using Ollama, rather than sending your entries to a cloud AI service. Your writing never leaves your computer, even when you use the AI features.

Does an on-device AI journaling app work offline?

Yes. Because the AI runs locally rather than in the cloud, Encrypted Diary's AI companion works fully offline, with no internet connection required to use its AI features.

How much does Encrypted Diary's AI journaling app cost?

The license is a one-time payment of $79 that includes the diary and the AI companion, with no required subscription. An optional $29/year add-on provides software updates and encrypted cloud backup.

Can I try the AI journaling app for free?

Yes. Encrypted Diary offers a free 14-day trial of the full application, including the AI companion, with no credit card required.
