Everything you need to know about Proven Ink authentication services
Proven Ink uses trained artificial intelligence and machine learning to analyze signatures with incredible accuracy, comparing patterns, stroke consistency, and pressure variation to provide you with a confident analysis and detailed guidance.
Proven Ink is designed as a fast, affordable authentication analysis—giving you a reliable confidence guidance before you invest time and money in official grading. While we don't replace PSA or JSA's formal certification, we help you screen items upfront, avoid obvious fakes, and make smarter decisions about which autographs to authenticate officially.
PSA and others are gold standards in formal authentication, and we respect their expertise. The average person spends $40 and weeks to see if their autograph is real. Proven Ink is not meant to replace official certification but to complement it by offering quick, unbiased analysis that can save you money and time. Think of it as a first line of defense—helping you identify high-confidence signatures or spot potential issues before committing to full authentication.
No digital tool or organization can guarantee 100% authenticity, and we are transparent about that. Proven Ink app provides a data-driven confidence score and detailed analysis to help guide your decisions. For official authentication, we always recommend using trusted legacy authenticators like PSA, JSA, or Beckett that can back up their authentication with an insurance claim.
Proven Ink's AI is trained on thousands of verified authentic and forged signatures and continuously improves with new data. It's designed to match expert-level pattern recognition and highlight subtle signature traits, but it's a tool to assist—not replace—human experts. It provides a reliable confidence score and highlights areas for closer inspection.
Full authentication with PSA or others often costs hundreds of dollars and weeks of your time, especially if you have valuable autographs. Proven Ink helps you prioritize and filter so you only pay for official grading on autographs with strong confidence scores, saving you money and effort.
Use it as a trusted preliminary tool to: quickly evaluate multiple autographs, spot potential fakes before investing in full grading, gain detailed insights into signature patterns, and support buying, selling, and collection decisions. It's especially valuable for experienced collectors and resellers who want to streamline their workflow and reduce risk.
Yes! Proven Ink's Free Plan offers 3 scans per month with basic confidence ratings and analysis summaries so you can try the service risk-free.
If you occasionally authenticate a few signatures, start with the Free or Signature Plan. If you regularly scan items or run a small business, the Collector Plan offers more volume and features.
Yes! Paid plans provide downloadable AI-generated reports you can save or share with buyers, sellers, or fellow collectors.
Currently, official authenticators do not accept Proven Ink's reports in lieu of physical examination. Proven Ink's reports are intended as pre-authentication guides for your personal use or to share with buyers to increase trust but do not replace formal certification.
Absolutely. Instead of paying a premium to authenticate high value autographs, get an analysis to make sure grading will be worth something. Not all objects and celebrity autographs are worth the same so make sure to do research regarding the value of your item.
