Decentralized · offline-first · on-device AI

Your decentralized
second brain.

Capture notes, connect them into a knowledge graph, share on an open network, and ask an AI that runs on your phone — not in someone else’s cloud.

UNIUN feed — notes from the people you follow, in time order

One primitive

It all starts with a note.

A note is the atom of UNIUN. The same note becomes a feed post, a thread, a node in your graph, a channel message, a DM, or context for your AI — and it’s never lost.

Create. Reflect. Transform.

Three surfaces, one mind — named for the trinity that creates, sustains, and transforms.

Brahma · Create

Write & connect

Author notes and build your knowledge graph on an interactive canvas. Every reference you draw is an edge.

Vishnu · Reflect

Feed & messages

Follow people in a time-ordered feed, join channels, and message end-to-end encrypted — the social side.

Shiv · Transform

Your on-device AI

Chat with your own notes, fuse ideas with Nataraj, and run autonomous Gana agents — all on your phone.

How UNIUN works

Three ways to build your Brahman.

Your knowledge graph grows three ways — named for the trinity that creates, sustains, and transforms.

UNIUN knowledge graph — notes and the connections you draw between them

01Brahma · create

Create your own thoughts.

Brahma is the act of creation. You author notes and, in authoring them, build the graph — every reference an edge, every note a node in your Brahman.

Write notes — the atomic unit of UNIUN — plain thoughts, captured permanently.
Draw connections — reference notes as you write; every reference is a graph edge.
See the graph — an interactive canvas of your Brahman — compose new notes right over it.
Manas — curate named subsets of notes into focused lenses for your AI.
Drafts — work in progress that lives only on your device until you publish.

02Vishnu · share

Take in and share the thoughts of others.

Vishnu is the preserver — the social membrane where your Brahman meets everyone else's. Absorb thoughts worth keeping, and offer your own.

The Feed — a chronological stream from the people you follow. Time, not an algorithm.
Threads — follow any conversation as a tree of replies — and ask the thread itself.
Channels — public rooms, plus invite-only private channels with admin-controlled membership.
Direct messages — end-to-end encrypted; only the recipient is ever visible on the relay.
Saved & followed — keep a thought forever, or subscribe to a note's reference graph.

03Shiv · transform

Churn your thoughts into new ones.

Shiv is the transformer — the falling apple. It looks at the Brahman you already have and draws the connections latent in it all along. All of it runs on your device; none of it calls the cloud.

Shiv chat — talk to your notes or a single Manas, grounded by GraphRAG — branch into a tree.
Nataraj — a swipe-deck that fuses two or three of your notes into a brand-new idea.
Ganas — autonomous agents that watch a surface, reason over a Manas, and act on a schedule.
Composer-chat — the same on-device intelligence, inline in every conversation.

Sovereignty by default

Notes are forever. You hold the keys.

UNIUN never publishes a deletion — nothing erases a note from the network. No company sits between you and your data, and your identity is a keypair only you control.

Start with one note

Build your network. Grow your knowledge.

Write a note, connect the context, and ask Shiv. UNIUN is live on iPhone — Android and desktop are coming.
