About Umbralog

An entertainment archive of UFO / UAP sightings, alien encounters, cryptid reports and large-scale paranormal events, arranged on one timeline (filter by category) and told the way the witnesses described them. Every story links to every source we found and carries a reputability score with a visible breakdown. Some images, all narration and the 3D models are AI-generated; see the Terms of Service.

What is generated, and how we label it

  • Summaries and story text are compiled by an AI investigator from the listed sources, then reviewed by a person before publishing.
  • Images. A story's main image is a real photograph when one exists, otherwise a photorealistic AI recreation of the reported moment. Pictures inside the narrated story are generated the same way: plausible, as if it really happened. Every picture and video carries a source tag in its corner: Found for photos, documents, maps, diagrams and footage we located, Generated for AI pictures, which also carry a small "AI generated" mark.
  • 3D models are approximations built from the written description.
  • Spatial reconstruction placements show, for every parameter, whether it was reported by witnesses or guessed by us.
  • Narrated versions are dramatizations.

Reputability score

A simple, versioned heuristic: independent sources weighted by quality, witness count and credibility, physical or instrument evidence, and official investigations. It gives the benefit of the doubt: only a confirmed hoax costs a few points, and a proposed conventional explanation is noted on the story without lowering its score. Every story shows its own breakdown. The underlying signals are stored so the score can be recomputed when the weights change.
