Note
Latest stable release: 0.11.0 (Windows x64). It adds an explicit, per-campaign choice between local assistant processing and a compatible sharing server; local remains the default. The installer is signed for the in-app updater, but not with Windows Authenticode. The 0.10.1 pre-release remains available for macOS and Linux. Those packages do not contain the 0.11.0 changes.
Important
Chronexus is entirely vibecoded. Its code, tests and documentation were written by AI coding agents (OpenAI Codex and Claude Code) following my instructions, not by hand. I made it purely for a personal need, as a player who wanted this tool, and out of curiosity about how far AI agents can be pushed in real software development. There is no company and no commercial goal behind it. If you prefer to avoid AI-generated software, consider this a fair heads-up. The in-app assistant is a separate, optional feature: it is off by default and the app works fully without it.
Chronexus is a desktop app for people who play a role-playing campaign, not for the game master. It keeps session notes, pages about characters, places and factions, the character sheet, inventory and spells in one local archive, linked with stable references. The interface defaults to English and offers 10 languages. Italian remains available, and existing language choices are preserved.
- The player’s point of view. What your character knows, suspects or was told: no GM secrets, no invented facts.
- A mention is not a fact. Naming two characters in one note does not make them allies: you declare relationships yourself, with source and certainty (confirmed, suspected, disproven, unknown).
- Your data stays yours. Local database, full
.nodexbackups, no account, no telemetry. - Built for the table. Autosave, keyboard shortcuts, dice roller and sheet one click away during play.
| Feature | In short | |
|---|---|---|
 |
Session journal | Visual and Markdown editor, autosave, [[Name]] mentions whose links survive renames |

| Method | For | How |
|---|---|---|
| Windows x64 installer | Everyone | Download Chronexus_<version>_x64-setup.exe from the latest release and run it |
| macOS, Linux (pre-release 0.10.1) | Testers | 0.10.1: DMG for Apple Silicon and Intel, .deb for ARM64 and x64, AppImage for ARM64, plus a Windows x64 installer; checksums in SHA256SUMS.txt |
| In-app update | Users of 0.4.0 or later | App settings → App updates |
| From source | Developers | See docs/DEVELOPMENT.md |
Requirements: Windows 10/11 x64 with WebView2 (already present on recent versions). The optional assistant needs an NVIDIA GPU; App settings → Local AI: components installs Ollama and the model without using a terminal.
First run: create a campaign, open a session and write. Type [[ to link a
character or place, then explore Codex and Graph.
Warning
The installer has no Windows Authenticode signature, so SmartScreen may ask for confirmation. In-app updates are still verified with a dedicated cryptographic signature. The 0.10.1 pre-release has no signatures at all (no Authenticode, no notarization, no updater signature) and is not offered by the in-app updater: on first launch use More info → Run anyway on Windows and right-click → Open on macOS. See the wiki.
- Backup and restore writes a
.nodexfile with every campaign and image, verified with SHA-256; restoring shows a preview and keeps a safety copy of the current data. - Periodic backups (App settings → Backup, off until you enable them): daily,
weekly or every N hours, only while the app is open and idle, into
Documents/Chronexus/Backup periodicior a folder you pick. Chronexus keeps the number of copies you choose and deletes only periodic copies it created and registered. - Before every update Chronexus creates and verifies a full backup in
Documents/Chronexus/Backup aggiornamenti(or the data folder, with a notice, when Documents is unusable): if it fails, the installation stops. - The herald announces new versions after a light startup check you can turn off. Installation starts only after you confirm.
Important
.nodex backups are not encrypted. Keep them somewhere safe, especially if the
folder is synced to a cloud service.
Optional and off until you enable it for a campaign. It answers using only that campaign’s notes and the wiki entries you approve, with citations you can reopen. It runs on the GPU through Ollama with cloud disabled and never changes notes, relationships or the sheet.
Note
Qwen3.8-27B and Gemma 4 12B are multilingual models, not trained on D&D: a valid citation does not guarantee a correct answer. Details in docs/AI_MODELS.md.
Chronexus is complete on its own. When your group wants more, the companion Chronexus Server is a small service that you host (a home server, a NAS or a cheap VPS, with Docker Compose):
- Your campaign on every device. Turn on synchronization for a campaign and each autosave also reaches your server. Offline edits wait and resume later.
- Share only what you choose. Every page, session, relationship, party member, sheet section or image stays private until you share it. Your party sees it read-only, with your name, its source and its certainty: a shared claim never becomes a campaign fact.
- Real conflicts, no silent overwrites. If two people edit the same item, both versions stay visible and you decide.
- Invitation-only accounts on your own infrastructure. Roles (owner, player, reader), revocable devices, verified server backups and recovery.
Connect from App settings → Campaign sharing, then pick what to share from each campaign's Sharing view. Without a server nothing changes: no account, no network, everything stays local.
Note
The server is in active development: its features are implemented and tested in source. Server 0.1.1 is available on GitHub; container deployment currently builds locally with Docker Compose, following the installation guide. Data is protected by HTTPS but is not end-to-end encrypted: the server operator can read what you upload. Android access is planned.
- No account, no telemetry, no campaign uploads, unless you connect your own Chronexus Server and choose what to send to it.
- Network requests start from your click (wiki, SRD catalog, updates, AI components) or from the startup update check, which only contacts the release channel and can be turned off.
- Wiki requests contain only the term or page you look up.
Delivered and open milestones, plus limits still to verify, are in ROADMAP.md; detailed status and the checks actually run in docs/STATUS.md.
The wiki explains every area of the app for players and has a developer section (architecture, data, sync, i18n, builds, QA, releases); its sources are in docs/wiki.
Chronexus is built with Tauri 2, Rust, React and TypeScript on local SQLite. Prerequisites, commands and checks are in docs/DEVELOPMENT.md; project rules in AGENTS.md. Reports and ideas are welcome in the issues.
