The public beta. Read this first.
Mune is open. You can create an account today. This page is the two minutes I'd want from you first: what Mune is, what the encryption actually protects, the one trade-off you need to understand, and what beta means.
A chat. A journal. A lock on both.
The chat is where you think out loud. You type what's on your mind, the AI asks the next question, and somehow what you're actually thinking comes out. It has no name, no persona, and it doesn't pretend to be your friend.
The journal is where the worth-keeping part lands. Write from scratch, write with the AI helping, or hand it a chat and edit the draft it makes. Read, change, or delete entries whenever. Export everything to a Markdown file on your computer in one click.
The lock is the part that makes the other two safe to use honestly. Everything you write is encrypted on your device before it leaves. The server holds locked boxes only you can open.
The full walkthrough is at how it works.
Locked on your phone. Before it goes anywhere.
Picture writing a letter, putting it in a locked box, and being the only person with a key. Your phone does the locking before the box leaves. The server holds the box. Nobody can open it but you. Not a hacker with the database, not a subpoena, not me.
The chat is the one honest exception. To answer you, the AI has to read your message, so it crosses to the AI provider in the clear, with no name or email attached. It is not trained on, and it is deleted on their standard schedule. Your stored copy stays encrypted like everything else.
The short version is at privacy. The whole machine, every box and every arrow, is at the deep overview.
One thing to understand before you sign up.
Your account password signs you in, and it can be reset by email like any password. The passphrase that unlocks your writing is different. Only you hold it, and nobody can reset it, including me. Onboarding gives you a 24-word recovery phrase as the one backup.
Lose both, and the writing is gone. There is no support ticket that brings it back, because a reset that could would be a back door. That is the cost of being the only person who can read what you wrote. Pick a passphrase you won't lose, and put the 24 words somewhere safe.
Built by one person. Still being built.
Beta means the encryption is real and the edges are rough. Screens will change. Small things will break, and I'll fix them. Your data is encrypted the same way it will be at 1.0; what's unfinished is the furniture, not the lock.
There's an iOS app in beta too. Same account, same encryption, built native.
If something breaks, or something reads wrong, write to me: fredrik@mune.so. I read every message myself, and a found hole is worth more to Mune than a compliment.
And the standing list, so nobody signs up for the wrong thing: not therapy, not a crisis tool, not a friend, not a fix. A place to think out loud, with a lock on it.
Read enough? The door is open.
An email gets you in. The passphrase and your first entry stay between you and your device.
