Private Cognitive Engineering

26 dimensions of your personality.
Computed locally. On your device.

Every other AI journal app sends your thoughts to OpenAI or Anthropic. InnerVoid analyzes most patterns directly in your browser — before a single line leaves your device.

How it works

What stays on your device.

InnerVoid strictly separates what runs locally and what goes to the cloud. Most patterns are built on your device — the AI only refines the text around them.

The local analysis alone reliably detects which personality dimensions and life areas emerge in your entries — fully offline, no AI call required.

On your device · always
  • 26 psychological personality dimensions
  • Theme clustering (8 life areas)
  • Crisis detection — 33 phrases, DE & EN, never transmitted
  • Mood, sleep & energy tracking
  • Word frequency & pattern recognition
Cloud AI · only on your request
  • Weekly analysis (text generation)
  • Monthly synthesis (text generation)
  • 3-month arc (text generation)
  • Socratic dialog (6 rounds)
  • Refinement of local scores into prose

Cloud AI is used only for text generation — and only when you actively request it. No automatic transmission.

InnerVoid analyses you — AI just explains what it found. If AI goes down, the app keeps delivering insights locally.

The difference

The Void vs. The Slop

Same message. Two different mirrors.

Standard AI
"I don't know why I never start even though I want to."
That sounds frustrating. Procrastination is very common and has many causes. Try setting small steps and celebrate every bit of progress. You've got this!
✦ Echo
"I don't know why I never start even though I want to."
You've written this four times now. In different weeks, about different projects — always the same structure: wanting, not doing, explaining why. The question isn't why you don't start. The question is what happens if you actually did.

Both responses are based on an analysis of your entries. The difference: standard AIs analyze every sentence you write in the cloud. InnerVoid recognizes your pattern locally — the AI only writes the text around it.

How it works

You write. Echo remembers.

You open InnerVoid when something happened — or when nothing happened and you know that's also a sign. You write. No format, no prompt, no pressure. Whatever comes out is what it is.

After each entry Echo analyzes what you wrote — not to judge you, but to name what you might not have said directly. Energy. Patterns. Contradictions. The gaps between the lines.

Over weeks a picture forms. Not the picture you have of yourself — the picture that emerges when you stop explaining yourself. Echo shows you what repeats. And asks why.

Socratic Dialog

A conversation that doesn't stop before it hurts.

No affirmations. No escape routes. Six rounds of Socratic questions — each building on your last answer.

You can't dodge it. Echo notices when you try.

Round 3 of 6 · Premium: daily · Free: once a week
Round 1
Echo
You write "I want more clarity." Clarity about what exactly — and why now?
You
About my direction. I don't know if what I'm doing still makes sense.
Round 2
Echo
When did it last make sense? And what was different then — you or the circumstances?
You
Two years ago. I think... I was more honest with myself back then.
Round 3 of 6
Echo
What do you know today that you didn't want to say back then?

★★★★★ Google Play

"I'm thoroughly impressed so far. The AI personality analysis is incredibly motivating — it doesn't just scan keywords, it reveals genuine long-term developments. Anyone who wants to do more than just offload thoughts and actually understand themselves through deep analysis won't find anything better. A mirror for your psyche that grows with you."

Samantha K., 28 · March 18, 2026
★★★★★ Google Play

"I was sceptical at first, but the 10-axis radar matches my current mental state 100 %! It's incredible how precisely the AI detects patterns. And since everything is end-to-end encrypted, I don't have to worry about my data at all. Absolute recommendation for anyone seeking real self-knowledge!"

Julian, 25 · March 27, 2026
★★★★★ Google Play

"The app is really great. Very easy to understand and beautifully designed. You can express your deepest thoughts and get honest — sometimes hard — feedback in return. I can only recommend it."

Common questions

What you want to know.

Is InnerVoid really private — or does someone read along?
With end-to-end encryption active, your entries leave your device only as unreadable ciphertext. We only see encrypted strings. Your key is derived from your passphrase via PBKDF2 and never leaves your device. Even in the event of a server breach, your data is worthless.
Does InnerVoid replace therapy?
No — and that's intentional. InnerVoid is a self-reflection tool, not a medical product. For mental health crises or conditions, professional help is irreplaceable. InnerVoid also shows you crisis resources when it detects relevant signals in your entries.
How is InnerVoid different from a regular journal or ChatGPT?
A journal listens but doesn't respond. ChatGPT responds — but without memory of your pattern. InnerVoid knows your history over weeks and months, recognizes repetitions, and asks questions that build on what you've already written. No compliments. Just clarity.
Can I export or delete my data at any time?
Yes. You can export all entries as PDF or JSON. The account can be fully deleted directly from within the app (GDPR-compliant, within 48 hours). Your data remains until you delete it yourself.
What happens when I cancel my subscription?
You keep all your entries and analyses. You automatically switch to Free at the end of the billing period. No hidden fees, no data loss. Cancel any time via app settings or email.
What exactly happens on my device — and what goes to the cloud?
When you write an entry, InnerVoid immediately analyzes it locally in your browser: 26 psychological dimensions, life areas, crisis signals. This analysis never leaves your device. Cloud AI (Claude, Gemini) is only used when you actively request a weekly analysis, monthly synthesis, or Socratic dialog — and even then only the necessary context is transmitted, never your entire history.
Why not everything in the cloud like other apps?
Because 90% of pattern recognition doesn't need cloud AI. Language-based personality analysis works surprisingly well with weighted keyword logic — in internal tests we reach ~70% agreement with the AI refinement. Cloud AI makes the result more nuanced and beautifully written, but the substance is built on-device. This saves API costs, protects your data, and works offline.
Which AI powers this?
InnerVoid uses Anthropic Claude and Google Gemini via encrypted API connections. The AI receives only the specific context per call (e.g. today's entry) — not your entire life story. With E2E encryption active, AI analysis is not possible since the AI would only see ciphertext.
