## What is UNIUN?

UNIUN is an offline-first decentralized social and AI platform built on Nostr.

Connect with communities, create and share notes, participate in channels, exchange direct messages, and organize knowledge in a privacy-focused environment where users own their identity and data.


## Version history (last 3 releases)

### 2.3.0 — 2026-08-15

What’s New

This update brings a more reliable and seamless AI experience to UNIUN.

 New Features

- QR Sign-In: Sign in to UNIUN Web by scanning a QR code from your phone—no password or key required.
- Ganas Cloud Models: Pin a UNIUN Cloud model specifically to Ganas, independently of the model used elsewhere in the app.
- Automatic Model Cleanup: Detect and remove incomplete or leftover model files to reclaim previously unused storage.

 Improvements

- Unified Model Selection: Shiv, Nataraj, and Ganas now use one consistent model picker.
- Onboarding: Interest suggestions are now loaded from the UNIUN backend, with loading and retry states.
- On-Device AI: Updated the AI engine for improved reliability during extended use.
- Model Switching: Changing models now takes effect immediately and safely, even during active generation.
- Ganas: Agents without a pinned model now automatically follow the app's currently active AI backend.

 Bug Fixes

- Fixed model pickers displaying internal routing IDs instead of model names.
- Fixed Nataraj showing an incorrect device compatibility error when no idea could be generated.
- Fixed cloud AI generation occasionally hanging or failing when requests overlapped.
- Fixed errors when switching or deleting models during active AI generation.
- Fixed Shiv responses becoming blank when leaving a chat while the AI was still responding.
- Fixed empty Shiv conversations appearing in chat history.
- Fixed duplicate connections occasionally being counted in Nataraj's knowledge-graph search.

### 2.0 — 2026-08-14

This release expands UNIUN's inference, identity, and offline networking capabilities.

### Added
- **UNIUN cloud inference.** Use hosted AI models from Shiv with built-in model selection,
  credit usage, and mobile payment support alongside on-device inference.
- **QR identity recovery.** Sign in on another device by scanning a secure QR code instead of
  manually transferring identity credentials.
- **Offline mesh sync.** Nearby devices can discover each other over local transports and securely
  synchronize notes, follows, groups, Manas collections, Ganas, and other user-owned data.
- **Surrounding notes.** Discover notes shared by nearby mesh peers in a dedicated feed.

### Changed
- Onboarding interest recommendations are now loaded from UNIUN's service so suggested accounts
  can be updated without an app release.
- Expanded repository, gateway, mesh, and integration test coverage.

### Fixed
- Improved cloud-model selection, credit accounting, inference UI, login, and sync reliability.

### 1.0 — 2026-07-03
