Tool profile · Publisher documentation
GPTZero is a tool for analyzing text with AI detection scores and sentence by sentence analysis. Its supplier documents a simple flow: paste your text to get an overall AI score and advanced sentence by sentence analysis. LE LABO IA has not tested the product, and this profile relies on the public documentation of its supplier. A score alone does not prove the origin of a text, so treat results as signals to contextualize rather than conclusions. Pricing shown here follows the supplier's pricing page as checked, with Premium at 12.99 USD per month billed annually for 300,000 words per month and Professional at 24.99 USD per month billed annually for 500,000 words per month. Monthly prices outside the annual view are not confirmed, and the announced 45 percent annual saving is part of an annual view that should be checked with the supplier.

Paste a text to review an overall AI score alongside sentence by sentence analysis, per the supplier documentation. Use the sentence level view to see which parts of a text drive the score before making any judgment. Apply the tool as one input in a broader assessment, since a score alone does not prove the origin of a text.
The supplier documents a free entry point and paid tiers: Premium at 12.99 USD per month billed annually for 300,000 words per month, and Professional at 24.99 USD per month billed annually for 500,000 words per month. Monthly prices outside the annual view are not confirmed, and the announced 45 percent annual saving belongs to an annual view. Check current prices, word quotas, availability and terms with the supplier before committing.
LE LABO IA has not tested GPTZero, and this profile relies on the public documentation of its supplier. Quotas, territorial availability and terms of use are not confirmed and should be checked with the supplier on the day you subscribe. An AI detection score is not proof of origin, so contextualize the result and avoid automatic conclusions.
Before committing, paste a text you know well and compare the overall score with the sentence by sentence view on the supplier site. Check whether the free entry point covers your expected volume, and confirm the monthly price if you do not want annual billing. Review the word quota tied to each plan against your real usage. Verify availability and terms directly with the supplier, since these points are not confirmed here.
