Academic proofreading, plagiarism checking and AI-powered writing tools in one place
A vetted academic editor reviews your paper within hours and returns tracked changes, comments and an explanation letter.
Scans your document against a large web and publication database to surface potentially unoriginal passages before submission.
Flags text likely generated by large language models and offers a rewriting mode aimed at making AI-assisted drafts sound more natural.
Creates and verifies references in APA, MLA, Chicago, AMA, IEEE and ACS styles from a URL, DOI or title search.
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.
