ἔν·δον Greek adverb “within; in one’s inner self.”
An AI support for reflection, journaling and mood, built for the thoughts you haven’t finished having. Private, awake when you are, and honest that it is not a therapist.
43+ already waiting.
Every word is private and encrypted. This means we don’t see your chats.
Sometimes you just need to speak honestly and be yourself. You bring the attitude, we bring the space.
You can finally stop winning arguments in the shower.We’ve all been hit with a mid-argument and then it hits, “you’re being so irrational.” We know it’s frustrating, and while you don’t need a therapist you want to discuss it. Endon unpacks the situation, without group chat bias.
We all have a friend who crossed a line. You want to bring it up without starting World War III over coffee. But how? Discuss with Endon the awkward “that bothered me” talk until you find the exact right words to protect your peace.
Nobody pushes your buttons quite like family. When you hang up the phone, you don’t need an intervention, you just need five minutes to vent. Unload the frustration with Endon, get a calm perspective, and protect the family peace while bettering your relations with them.
Come on, we’ve all confidently said “no problem!” to something that is definitely a problem. Why do we do this? And is it time to use “NO”? Endon is not just about discussing, it’s also about putting you first and helping you grow as a person and achieve the best version of you.
Four premium practices, talking, writing, noticing, breathing. And two promises underneath them that matter more than all four.
Some things are easier said than typed. No script to follow, no diagnosis to reach for — just room to think out loud until it makes a little more sense.
Endon follows your pace, reflects back what it hears, and helps you find the shape of how you feel.
You don’t need to be a university professor. Half-sentences, no punctuation, typos — we can understand you.
Not a streak to protect. Just a few seconds, most days, to ask how you are actually doing.
Guided sessions chosen for the state you are in right now, not a 30-day program.
Troubling moments don’t keep office hours. Endon’s awake whenever you are. No appointments, no waiting room.
Endon never pretends to be human. It’ll tell you what it is — every time you ask, and some times you don’t. Honesty about what it is comes before everything else it does.
Wherever you already are, the phone is in your pocket. Try the chat.
People hesitate to bring AI anywhere near mental health, and they are right to. So this part comes before the clever part.
Full detail lives in the privacy policy, written in plain language rather than legalese.
Every conversation and journal entry is encrypted and private. Nothing is sold, nothing feeds advertising, and you can delete all of it from the app in one tap.
Endon will never pretend to be a person. Every interaction is clearly with an AI system. Transparency is a feature here, not fine print.
Not therapy. Not a medical device. Not a crisis line. A data protection impact assessment was completed before launch, and processing runs on explicit consent you can withdraw whenever you like.
If you are in immediate danger, call 112 now. In Greece, 1018 is the suicide prevention line and 116 123 is emotional support, both open around the clock. Endon watches for signs of serious distress, but detection is imperfect and never stands in for emergency services. Crisis features are never behind the paywall.
A small team in Greece. Two engineers who write the code, and two people who decide where it should go and who it should reach.
One of the two engineers behind Endon. Serafeim builds the platform and website end to end, from AI integration and security to the infrastructure it all runs on.
Shapes where Endon is going: product direction, commercial strategy and partnerships. Started Endon from personal experience with the barriers to emotional support.
One of the two engineers behind Endon. Konstantinos builds the platform and website end to end, from architecture and system design to the interfaces people use.
Brings Endon to the people it is for: marketing, social campaigns, community growth and partnerships across Greece and Europe.

Endon is an AI-powered emotional wellbeing app designed to help you reflect, process your thoughts, and feel more supported. It combines conversational AI support, guided journaling, mood tracking, and meditation tools. Endon is not a therapy app; it is a wellbeing companion available whenever you need it.
No. Endon is designed to complement professional support, helping you reflect between sessions, track emotional patterns, and feel less alone in difficult moments. It is not a substitute for diagnosis, treatment, or clinical intervention.
No. Endon does not diagnose, assess, or treat mental health conditions. It does not provide medical, psychiatric, or psychological advice. If you are concerned about your mental health, please speak to a qualified healthcare professional.
No. You are always talking to an AI. Endon will never claim to be human or pretend to be a person. This is a core principle we will never compromise on.
Everything you share with Endon is encrypted and stored securely on EU-based servers. Only you can access your content. We will never sell it, share it with advertisers, or use it for any purpose outside of providing and improving Endon for you. You can delete your data at any time from within the app.
Pricing is not final yet. What we can commit to now: there will be a free tier that is genuinely useful rather than a trial, and the safety features will never sit behind the paywall. Everyone on the waitlist hears the pricing before launch, not after.
Endon includes safety features designed to detect signs of serious distress. However Endon is not a crisis service. If you are in immediate danger please contact emergency services now. Greece: 112 (Emergency), 1018 (Suicide Prevention, 24/7), 116 123 (Emotional Support, 24/7). EU-wide: 112 and 116 123.
