## 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.

**料金とプラン:** Freemium plus paid plans. A free tier provides core detection with character limits per scan, while paid individual and institutional plans unlock advanced scan modes, higher limits, writing reports, and classroom integrations. Enterprise and API access are quoted separately.

- **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.
- **Writing process verification:** Writing replay and advanced reports offer evidence about how a document was produced, useful for academic integrity workflows.

**強み:** 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

**制約・デメリット:** Detection is probabilistic and can flag polished human writing or miss lightly edited AI text; Free scans are capped by character count, and useful reporting features require payment; Lean heavily on a single score without human judgment can lead to unfair accusations

## 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.

**料金とプラン:** 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. Because fees scale with turnaround and submission type, check that page for current rates rather than relying on an estimate.

- **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.
- **Deep Pokemon set coverage:** Coverage starts with Pokemon across modern and vintage eras, including promo sets, Japanese-exclusive releases and anniversary collections, with additional TCG and sports card categories scheduled for future release.

**強み:** 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

**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
