Enterprise and API access are quoted separately. Validoe: 有料。Validoe is a paid service with pricing tied to the item type and the turnaround speed you choose; the site publishes a dedicated pricing page.

GPTZero

GPTZero is an AI detection platform for identifying machine-generated text. It combines a text detector with a Chrome extension, a plagiarism checker, writing-process verification, and educator-focused classroom tools.

Sentence-level AI detection

Paste text or upload a document and get an overall AI probability score plus a sentence-by-sentence breakdown of which parts look machine-written.

Multi-model coverage

Flags AI text from major model families including ChatGPT, Gemini, Claude, Llama, and others, rather than training for a single model.

Browser and docs extensions

A Chrome extension and Google Docs add-on bring scanning into Gmail, Docs, Classroom, and other surfaces you already work in.

Plagiarism checking

Checks content for copied passages from outside sources so you can separate AI-generation questions from originality questions.

強み・メリット

+Sentence-level highlighting shows why a passage was flagged instead of only giving a score
+Covers text from many different AI model families, not just one chatbot
+Integrations with Chrome, Google Docs, Canvas, and Google Classroom fit existing school workflows
+Publishes concrete compliance claims (SOC 2 Type II, FERPA, GDPR, CCPA) that institutions can review

Validoe

Validoe is an app that authenticates and pre-grades Pokemon cards, and reviews graded slabs and sealed product, by combining a global team of card specialists with AI assistance. You photograph the item, submit it for verification, and receive a report covering authenticity, grade potential and any signs of tampering - often within minutes.

Expert-backed authenticity verification

Submit a card, slab, booster pack or sealed box for review by a global team of authenticators, supported by AI. You get an Authentic or Replica verdict with the evidence behind it, rather than a score alone.

Pre-grading for raw cards and packs

For raw cards and unopened packs, Validoe assesses condition and grade potential before you commit to an official grading submission, helping you judge whether a card is worth the time and cost.

Re-grading for slabs

Already-slabbed cards can be re-assessed to flag possible mislabeling and to surface grade or value potential you may have missed - useful when evaluating a slab on the secondary market.

Reports in as little as 10 minutes

Capture card images in the app, submit for review, and choose a turnaround. Reports can be returned in as little as ten minutes, with watermarked images and written commentary from the authenticator.

強み・メリット

+Uses human specialists rather than AI alone, which matters for high-value authenticity calls
+Covers the full chain from raw cards and packs to graded slabs and sealed boxes
+Fast turnaround options, with reports possible in around ten minutes
+Reports include images and written authenticator commentary, not just a verdict
+Broad Pokemon set knowledge across modern, vintage, promo and Japanese-exclusive releases

制約・デメリット

–Turnaround and depth depend on the selected service level, so instant answers are not guaranteed
–Currently focused on Pokemon cards; other TCGs and sports cards are still rolling out on a published schedule
–You still need to photograph the card yourself, and poor photos will limit the usefulness of any report
–It is an independent service - it does not replace or speak for the established grading companies
