Private AI Journal

What do your words reveal about you?

InnerVoid reads patterns in your writing that you can barely see yourself. 26 personality dimensions, computed directly on your device. No account needed to try it.

01 - Live Mirror
Live Demo

Type a sentence. See which patterns InnerVoid detects locally.

The text stays in your browser. InnerVoid counts matches from the trait lexicon and shows which psychological axes resonate in your language, as a signal, not a diagnosis.

02 - Big Five Radar
Personality from Language

Five dimensions. Derived from your own words.

InnerVoid maps recurring language signals to the Big Five: Openness, Conscientiousness, Extraversion, Agreeableness, and emotional Reactivity. From your journal entries, not questionnaires.

03 - Encryption
Maximum Privacy

Your thoughts. Readable by no one but you.

InnerVoid can encrypt AI insights with AES-256-GCM. Only you know the key. Press the button and see for yourself.

Plain text
I notice how the fear of failure keeps catching up with me. But today I drew a line. That feels strong.
AES-256-GCM · End-to-End

Only you know your passphrase. InnerVoid sees only ciphertext. Even in the event of a server breach, your entries are unreadable to anyone.

"I was sceptical at first, but the 10-axis radar nails my current mental state perfectly. It is incredible how accurately the AI recognises patterns. And since everything is end-to-end encrypted, I don't have to worry about my data at all."
