Questions
What people ask before downloading
What is the best private AI journaling app?
The right AI journal app is one that is both private by design and thoughtful in how it responds. InnerSight encrypts your entries end-to-end on your device — even we can't read them — and its AI companion, Iris, is built on Brief Cognitive Behavioural Therapy principles rather than generic chatbot patterns. Free to start, no sign-up required.
How is InnerSight different from using ChatGPT as a journal?
ChatGPT tends to agree with you and offer suggestions. Iris is trained to sit with uncertainty, ask one thoughtful question at a time, and gently challenge cognitive distortions rather than reinforce them. Your entries also stay encrypted on your device — nothing is used to train AI models, per our providers' terms.
Is my journal really private? What does end-to-end encryption mean?
Your entries are encrypted on your device with a passphrase only you know, using AES-256 with Argon2id key derivation. What reaches our servers is ciphertext we cannot decrypt. No backdoors, no employee access, no ads, and your data is not used to train AI models.
Do I need to create an account to use InnerSight?
No. You can journal immediately without signing up — an anonymous session is created on your device automatically. Create an account later if you'd like to sync across devices or restore on a new phone. Everything works either way.
How does AI-assisted journaling actually work?
Write in your journal like you always would. When you want to reflect deeper, tap Ask Iris — a chat opens where Iris asks thoughtful questions grounded in CBT (Cognitive Behavioural Therapy). At any point you can Auto Update your journal entry with the insights that came out of the conversation.
Can InnerSight help with anxiety, stress, or difficult emotions?
InnerSight isn't therapy and isn't a replacement for a mental health professional — but it can support the reflective work people do alongside therapy or on their own. Iris uses evidence-based CBT techniques like naming cognitive distortions, Socratic questioning, and helping you separate thoughts from facts. If you're ever in crisis, Iris will direct you to a local support line.
Is InnerSight free?
Yes — journaling, streaks, and up to 10 Iris conversations per day are free forever. Premium (£7.99/month or £49.99/year with a 7-day free trial) unlocks unlimited Iris conversations, unlimited Auto Updates, photo attachments, PDF export, and entry analysis.
Which devices does InnerSight run on?
InnerSight is available on iPhone and iPad on the App Store. Android support is not currently available.
