Trovifact

An evidence-first collector copilot

Know what
you’re holding.

Photograph both sides of a coin or banknote. Trovifact helps you read the clues, compare catalogue candidates, and save what you know—without pretending uncertainty does not exist.

Trovifact on your phone

See a coin become
a discovery.

Follow the mobile pilot from two photographs to a possible catalogue match, an indicative value guide, and your own decision about what to save.

60 seconds · Illustrated pilot walkthrough · English synthetic narration. Screens are condensed for clarity; the mobile demo focuses on coins. Read the transcript.

The value guide displays Numista’s indicative estimates by issue and condition, drawing on user evaluations and online sales. It does not grade or appraise your item.

Evidence before answers.

Alternatives before overconfidence.

Your confirmation before identity.

The approach

From two photographs
to a record you can trust.

  1. 01

    Capture both sides

    Guided front-and-back photography helps keep rims, corners, legends, dates, and other useful details visible.

  2. 02

    Read the evidence

    Trovifact separates what is visible in your images from catalogue facts and model inferences.

  3. 03

    Compare candidates

    See supporting clues, conflicts, and missing details across up to three possible catalogue matches.

  4. 04

    Confirm—or leave unresolved

    You decide what becomes part of your collection record. Uncertainty remains a valid, visible outcome.

Clear by design

A candidate is not a verdict.

Identification should show its work. Trovifact is designed to explain why a candidate may fit, where it conflicts, and what would help distinguish it.

  • 01 What the photographs visibly show
  • 02 What the catalogue states
  • 03 What the model infers
  • 04 What you confirm or correct

Deliberately focused

A small pilot,
built to learn carefully.

Trovifact is currently in private development. The first pilot will be invitation-only, free to testers, and focused on a dependable capture-to-collection experience.
