How It Works

Our process keeps submission simple while giving the AI enough time and context to produce a useful confidence-based assessment.

1. Upload

Submit listing photos or autograph images with the context our system needs to review the signature properly.

2. AI analysis

The autograph is compared against reference patterns, signature features, and consistency signals across the item.

3. Receive report

Get a clear result with supporting notes so you can decide whether to buy, hold, sell, or investigate further.

Why AI autograph authentication takes 24 to 48 hours

The review window is part of the quality process. Our system compares signature shape, stroke flow, pressure patterns, reference consistency, and image-level details before returning a confidence-based result. That extra time helps reduce shallow or rushed conclusions and turns turnaround into a trust signal rather than a delay.

What happens during review

  • Deep comparison against visible signature features
  • Reference matching across likely signature patterns
  • Confidence scoring based on visual consistency
  • AI-assisted review process designed for collector decisions

Frequently Asked Questions

How accurate is AI autograph authentication?

AI autograph authentication can highlight visual patterns, inconsistencies, and reference matches that help collectors make better decisions. It should be treated as a strong decision-support tool rather than a guarantee, which is why Signatrue focuses on clear confidence-based reporting.

Why does AI autograph authentication take 24 to 48 hours?

The turnaround allows time for deeper comparison, reference matching, confidence scoring, and an AI-assisted review process. We use that window to avoid rushing the analysis and to return a more useful result.

Can I use eBay images for AI autograph authentication?

Yes, if the listing images are clear enough to show the autograph well. Better photos usually improve the quality of the analysis, so close-up images and multiple angles are always helpful when they are available.

Can I verify an autograph online before I buy it?

Yes. Online verification is designed for that exact use case. Collectors often use Signatrue before bidding or purchasing so they can reduce risk before committing money to a signed item.

Does AI autograph authentication work for signed memorabilia?

Yes. Signed memorabilia is one of the main use cases for this process, including jerseys, balls, photos, gloves, cards, posters, and similar collectible items.
