What is Vitni. The one-page answer.
Vitni is a private, end-to-end encrypted journal with a chat built in. The chat helps you finish a half-formed thought. The journal keeps the part worth keeping. This page is the whole product, stated plainly.
An encrypted journal a conversation writes for you.
Most journaling apps hand you a blank page and a date. Vitni starts from the other end. You open a chat and type whatever is actually in your head, in whatever shape it arrives. The AI reads it, reflects it back, and asks at most one question at a time. Often it asks none.
When something lands, you can turn the conversation into a draft journal entry. The draft is editable before anything is saved. Keep it, change it, or throw it away. What you keep is encrypted on your device before it leaves it, and the server stores boxes only you can open.
In the product, the chat is called Reflect and the record is called Journal. On this site we mostly say the chat and the journal, because that's what they are.
Journal. The part you keep.
The journal is the record, listed newest first. There are three ways an entry gets made: you write it yourself on a clean page, you write it with the AI helping you shape it, or you generate a draft from a past chat and edit it before saving. Nothing is saved until you save it.
Entries are encrypted with AES-256-GCM in your browser before any network call. Entries you write by hand never touch the AI at all. And everything you've written can be exported as decrypted Markdown from settings, any time, in one click.
Reflect. The part that asks.
Reflect is where the time goes. It has no name, no persona, and no backstory. It doesn't perform empathy and it doesn't hand out advice you didn't ask for. It mirrors what you said, notices contradictions, asks for specifics, and stops when the thought has found its shape.
The full interaction design is at how Reflect responds.
How the encryption works. Two tiers, stated honestly.
Picture writing a letter, putting it in a locked box, and being the only person with a key. Your device does the locking before the box leaves. The server holds the box. Nobody can open it but you.
The chat is the one honest exception. To answer you, the AI has to read your message, so it crosses to Anthropic, the AI provider, in the clear over an encrypted connection. No name, email, or IP travels with it. It is not trained on, and it is deleted under Anthropic's standard retention window of up to 30 days. Your stored copy stays encrypted like everything else.
The short version is at privacy, the whole machine is at the deep overview, and you can watch the lock happen at encryption.
Not therapy. And not four other things.
Not therapy, and not a replacement for it. Not a crisis tool. Not a chatbot friend with a name. Not a mood tracker: no mood grid, no sentiment score, no calendar of coloured days. Not a social anything: no feed, no likes, no followers, and nothing you write is ever visible to another user.
It also doesn't chase you. No streaks, no notifications engineered to pull you back, no gamification. Coming back is your choice.
Not another AI assistant. A different job.
ChatGPT is built to produce answers. Vitni is built to help you hear your own thought. A general assistant treats a feeling like a task and hands you a plan. Reflect hands the thought back to you, slightly less blurry, and lets the journal keep it.
The full comparison, including the same thought fed to both, is at why Vitni.
Vitni means witness. The older kind.
Vitni is Old Norse for witness, the older form of the Norwegian vitne. The name is about witnessing your own thinking, not about giving testimony in court. Watching is what other apps do. Witnessing asks for nothing back, and the witness is you, because everything you keep is encrypted on your device before it leaves.
Vitni was called Mune until July 2026, when another company turned out to hold that word. Same product, same founder, same architecture. Essays published before the rename still say Mune, and each one carries a note saying so.
A web app in public beta. Built by one person.
Vitni runs in the browser at vitni.app and is free while it's in beta. There's an iOS app in beta too, with the same account and the same encryption. It's built by one person, Fredrik Haugen, in Oslo. The longer plan is free at the core, paid for what scales. Never ads, never data sales.
That's Vitni. The rest is trying it.
An email gets you in. The passphrase and your first entry stay between you and your device.
