A private Windows desktop studio for reflection, decisions, and creative play with traceable randomness. Sortilune combines daily constellations, card draws, decision receipts, writing prompts, generative artwork, live planetary sound, small practices, multi-step projects, and a searchable local archive in one portable app.
The name Sortilune (sortilege + lune) means “moon-cast lots”: the lots are drawn from public scientific signals when available, with their source recorded beside the result.
| Area | Feature | What it does |
|---|---|---|
| Home | Today | Builds one replayable daily constellation from a verified NIST pulse, with Oracle, Constraint, Diary, Symphony, and practice cues. |
| Consult | Oracle | Draws from Tarot, I-Ching, Runes, or the original Cosmic deck and creates a deterministic illustration. |
| Consult | Constraint | Draws a small creative or observational discipline to accept, pass, or save. |
| Decide | Decider | Chooses between weighted options and creates a portable result receipt. |
| Decide | Lottery | Provides coin, dice, wheel, name, number, and shuffle tools with optional receipts. |
| Create | Diary | Saves locally editable Markdown entries anchored to reflective prompts. |
| Create | Canvas | Produces six kinds of entropy-seeded SVG artwork, PNG exports, and an optional wallpaper action. |
| Observe | Symphony | Turns earthquakes, weather, and beacon pulses into a live score that can be replayed and exported as WAV or MIDI. |
| Verify | Beacon | Creates and rechecks a reproducible checksum bound to a public NIST pulse. It is not a trusted timestamp. |
| Workspace | Projects | Guides three built-in multi-step creative workflows and keeps every saved result connected. |
| Workspace | Practices | Offers gentle recurring activities with pause, rest-day, skip, and private reflection support. |
| Memory | Archive | Searches, filters, annotates, groups, and inspects local records without rewriting their source files. |
| Memory | Journal Export | Turns selected Archive, Today, and Project material into self-contained HTML or Windows Print-to-PDF output. |
| Settings | Content packs | Imports, enables, disables, updates, exports, and removes validated local content packs. |
The adaptive navigation rail, command palette (Ctrl+K), three themes, compact layouts, keyboard focus states, and reduced-motion support are shared across the app.
- Download
Sortilune-0.2.0-windows-x64.exefrom the Releases page, or build it from source. - Double-click the executable. No installer, account, admin rights, Python, Docker, or GPU is required.
- Start on Today, or use the navigation rail to open another feature.
Requirements: Windows 10 version 1803 or newer, or Windows 11, with Microsoft WebView2 Runtime. The portable executable expects WebView2 to be installed; supported Windows versions normally include it.
There are no accounts, analytics, telemetry, crash uploads, background services, autostart hooks, or automatic update checks. Sortilune runs only while its window is open.
User data stays under %APPDATA%\com.sortilune.desktop\:
archive\contains readable JSON, Markdown, and artwork files;- Projects, Practices, pack state, annotations, and derived Archive cache data use versioned local files;
- deleting or replacing the portable executable does not delete this app-data directory.
The app contacts only five allowlisted public-service hosts: NIST Beacon, USGS Earthquake, Open-Meteo, random.org, and ANU Quantum. Requests do not contain prompts, decisions, diary text, project notes, or Archive content. Most tools fall back to clearly labeled on-device cryptographic randomness when offline; features that explicitly require live NIST or live planetary data fail visibly instead.
See Privacy and network behavior and Data and export formats for the exact release contract.
| Source | Use |
|---|---|
| NIST Randomness Beacon 2.0 | Verified public pulses for Today, Beacon, strict Decider, and the preferred entropy chain |
| USGS Earthquake feed | Seismic entropy and Symphony events |
| Open-Meteo | Weather entropy and Symphony wind state |
| random.org | Atmospheric-noise entropy |
| ANU Quantum | Quantum-number entropy when its public endpoint is available |
crypto.getRandomValues() |
Clearly labeled local fallback |
Source metadata is part of saved results. A matching Beacon checksum proves internal consistency with the referenced public pulse; it does not prove authorship or creation time.
The supported release target is the portable Windows executable:
npm ci
npm run tauri:build:portableThe artifact is src-tauri\target\release\sortilune.exe. Full prerequisites, quality commands, and smoke-test instructions are in BUILD.md.
Sortilune uses TypeScript and JavaScript modules in a Vite WebView2 frontend, with a small Rust/Tauri boundary for scoped HTTP, local persistence, native dialogs, filesystem observation, and wallpaper application. Runtime modules are lazy-loaded by route; imported content is data-only and cannot execute code.
- This release is built and certified as a personal, single-user Windows portable app. macOS and Linux are not release-certified targets.
- It has no cloud sync, account system, collaboration service, in-app encryption, or auto-updater.
- Journal PDF output uses the installed Windows print dialog; HTML is the durable self-contained export.
- Imported packs customize content, not executable code or entropy sources.
Sortilune depends on public services and datasets from NIST, USGS, Open-Meteo, random.org, ANU, and Natural Earth. Full attributions and third-party notices are in CREDITS.md.
