ABOUT ZEROGPT

ZeroGPT's plan tiers are confirmed from the vendor pricing page, but the prices themselves render client-side after load and were not present in the fetched markup, so no figures are recorded rather than repeating third-party numbers. This record is flagged needs_review until the tier prices are confirmed. The free tier is verified as free forever with no card required.

OVERVIEW

Who is it for?
Students, writers and small teams who want a no-cost AI check, plus developers embedding detection through an API.
Problem
Most detectors either cap free usage hard or hide sentence-level detail behind a subscription, which makes a quick sanity check awkward.
Solution
ZeroGPT offers a free forever tier with no card required and reports detection at document, paragraph and sentence level alongside probabilities and statistics. Paid Personal, Business/EDU and Enterprise tiers exist, and the API bills pay-as-you-go from a prepaid balance.
What makes it unique
A genuinely free entry point paired with a broader toolkit - plagiarism, paraphrasing, summarising, grammar and translation - rather than detection alone.
