What is an AI journal app?
An AI journal app is a journal with AI added to it. The AI is there to ask questions, show patterns or help you reflect on what you write, and it differs by app: Mindsera's asks questions and shows patterns, Reflectly's helps you structure daily thoughts, and Day One lists its AI features only in the Gold plan. Stella is not one of these: you tell her what happened and she replies, and there is nothing to log.

Should you write it down or talk it through?
Write it down if you want a record to come back to. Talk it through if you want a reply while something is on your mind. AI journal apps add AI to the first. Stella is the second.
If you would rather speak than type, our article Voice Journaling for Anxiety: A Simple Way to Start compares voice notes, writing and an AI conversation.
The key difference
A journal, AI or not, starts with you filling in a page. That suits a quiet evening, and it leaves you a written record to re-read. It can be harder when you are too wound up to type, or want something said back.
That is the moment for Stella. Tell Stella what happened, or what you keep putting off, by voice or text. She keeps what you've told her in mind, tells you straight but kindly, and helps you find the words or choose a small step when you're ready. No streaks, nothing to log.
When should you journal, and when should you talk to Stella?
You can do both: a journal for the evening, and Stella when something is on your mind.

Headspace and Calm
To wind down instead of writing, the two meditation apps are compared with Stella on their own page.
The honest take
If you like writing on a quiet evening, an AI journal app may suit you better than Stella does. She isn't trying to replace a journal: she is for when you would rather say it and hear a reply. A journal and a conversation do different jobs, and you can use both.
Stella is not therapy and is not a substitute for professional care. She is for adults, and not for someone in crisis.
How we made this comparison
StellaLabs makes Stella. Every statement here about another app comes from that company's own App Store listing, website or help pages (or an archived copy), or a regulator's public release, or, where the page says so, Apple's search results or whether a site loads, as of . Prices change, so check the listing before you buy; we did not test the other apps.
