®Make experience visible
Record more than what happened. Capture what you expected, what actually happened and which assumption you want to change.
A European AI initiative · In development
Your experience. The missing layer for personal AI.
What you learn from mistakes should not disappear. Fejlja is developing a private experience journal that gives structure to decisions, insights and better next steps. For you. And, in time, for AI that understands your context.
Today: project information and an interest list. No publicly available app yet.
From a moment to an insightContext → Decision → Outcome → Next step
01 / The idea
A mistake is an event. An insight is a beginning.
A language model knows a great deal. It does not automatically know the reasons behind your decision, the constraints of your project or the lesson you learned yesterday. Fejlja starts with that missing layer: structured experience you deliberately choose to record.
Patterns, not blame
Recognise recurring decisions and conditions. For personal reflection, a learning culture and clearer collaboration.
Prepare context for AI
In time, make selected insights useful to AI assistants. Deliberately, transparently and only with information you choose to release.
A deliberately simple example
“I used an AI answer without checking its source.”
Situation
A convincing market figure made its way into a presentation without verification.
Insight
Confident language is not evidence of factual accuracy.
New rule
For external facts: check the primary source, date and reference frame before using them.
The idea: future AI support could consider this explicitly shared rule when relevant. This is a proposed use case, not an integration available today.
02 / The principle
Not more data. Better connections.
Capture
Record the situation, decision and outcome. Leave out other people’s confidential information.
Understand
Separate assumptions, emotions and constraints from verifiable facts.
Learn
Write down one concrete insight and one testable rule for the next attempt.
Use deliberately
Reflect for yourself and, later, share selected material with a team or AI. The technical implementation is in development.
03 / Who is it for?
For people who think further.
We want to speak with people who want to make more of experience. Especially founders, knowledge workers, teams and developers of personal AI systems in Germany and Europe.
Founders & startups
Document assumptions, experiments and lessons clearly instead of repeating the same loop.
Teams & learning culture
Move retrospectives beyond blame towards concrete, traceable improvements. Not employee surveillance.
AI developers & research
Explore how curated experience could provide context for assistants. Conversations about RAG, memory and evaluation are welcome.
04 / Ambition & reality
Private by intention. Honest by description.

FAQ
The questions that matter.
What is Fejlja?
Fejlja is an initiative for a private error and experience journal. People should be able to structure their experience, learn from it and later use selected insights as context for personal AI.
Can I use Fejlja already?
Not as a publicly available app. This website presents the concept and collects expressions of interest and collaboration inquiries for further development.
Is it the same as an AI chatbot?
No. The focus is a knowledge foundation controlled by the person who creates it. A chatbot could be a future interface. The available integrations are still to be determined.
Will my data train large models?
This website does not upload journal data or offer model training. Contact and interest data are not sold as training data. A future AI product needs its own clear privacy and permission framework.
RAG, memory or fine-tuning: what do you mean?
Selected insights could later be retrieved as context for a request. This does not automatically change model weights. RAG, persistent memory and fine-tuning are different technical approaches.
What stage is the project at?
Fejlja is being developed as a European AI initiative presented by Hedonist Solutions. We welcome conversations about concrete uses, privacy and potential pilot projects.
How can I get involved?
Register interest or contact us about a pilot, research or media inquiry. Requests are reviewed personally. This is not a promise of admission to a testing programme.
