The methodical witness's toolkit

VigiSky Sentinel

A desktop app that applies a rigorous observation method: anchor the facts, verify the usual suspects, analyze the evidence, classify cautiously — and share only if you decide to.

Sentinel does not replace your judgment. It helps you not damage the data.

Note: the app interface is currently in French (an English version is planned). The analysis pipeline, charts and exported reports are understandable regardless — and this page tells you exactly what each feature does.

What the app does

🎬Video analysis: the signature is in the motion

Load your sighting video: every moving object becomes a dated event with its trajectory, angular speed and light curve. Aircraft strobe lights, satellite steadiness, meteor brevity — the engine recognizes them, and says so cautiously. It also measures authenticity clues (photon noise, micro-shake, frame cadence) to flag AI-generated or heavily processed videos — without ever crying fake. → The method explained

🔬Astronomy-grade photo analysis

The Deep Sky Engine analyzes your photo like an observatory: local sky background, extraction of every light source (sub-pixel centroid, FWHM, elongation), cautious classification — star, satellite trail, hot pixel, or signal worth a second look. A 24 Mpx photo takes ~0.2 s on an NVIDIA GPU; without one, the CPU takes over.

📁The Vigi-Sky case file

Each observation becomes a numbered, exportable investigation sheet: witness data, checks performed, analysis, verdict — and its limits, stated in plain words. Never "UFO detected".

🌌The Lab (bonus)

A CUDA galaxy simulator — one million stars, dark matter, the Milky Way-Andromeda collision, ring galaxies, live supernovae — to understand what "astronomical unknown" really means.

100% local. Sentinel works without an account and without a connection. Your photos, case files and notes never leave your computer unless you explicitly click "Share". No telemetry, no ads, no subscription.
Windows will show a warning at install time — that's expected. Sentinel is published by an independent developer and is not yet code-signed (a certificate costs several hundred euros a year). Windows SmartScreen will show "unknown publisher". To install:
  1. Click "More info"
  2. Then "Run anyway"
You can verify the file's integrity with the SHA-256 hash shown under the download button.
