Detect, humanize and verify AI content in one place
Scans up to 5,000 words at a time and highlights the specific sentences most likely to be flagged as machine-written, so you can see your text the way a detector sees it.
Rewrites AI-flagged passages with different sentence rhythms, vocabulary and tone, keeping your meaning while making the prose read like human writing.
Detectors for AI images, voice recordings, video and deepfakes, plus specialty document tools for checking whether a PDF or screenshot has been manipulated.
Detect and humanize directly inside Gmail, Google Docs or any web page without switching tabs.
AI-assisted Pokemon card authentication, pre-grading and re-grading
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.
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.
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.
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.
