AIGPTZero is a Claude and Gemini text detector that estimates whether a piece of writing is human-written, AI-generated or mixed. Usage is tracked per account, so past checks are easy to find. Reports can be downloaded as PDF, DOCX or TXT. Editors use it to screen submitted articles and guest posts. Independent tool, not affiliated with GPTZero. Freemium.
Submitted URLs are declarations until checked. Verification inspects published content and does not execute third-party tools.
Format finding: start with one H1 naming the site or project.
Quality suggestion: add a short summary blockquote before the file sections.
No Markdown links
The score measures observable documentation quality. Each component below lists its earned points, exact checks, and source observations. It is not a prediction of AI rankings or citations.

Confidence: high
One project H1 at the beginning: 0/10. Coherent content sections: 0/5. Documentation links organized in lists: 0/5. Non-repeated headings: 5/5.
10 H1 heading(s); starts with H1: yes.
H2 with content: no; no heading-level jumps: yes.
0 valid link occurrence(s) inside Markdown lists.
10 unique heading(s) out of 10; code examples are excluded.
How to improve: Start with one useful # project title. Organize documentation under meaningful ## sections and put relevant [Title](URL) links in Markdown lists. Avoid duplicate headings and skipped heading levels. These are quality checks: only H1 is required by the llms.txt proposal. Code examples do not earn heading points.
Resolvable HTTP(S) link syntax: 0/5. Unique documentation destinations: 0/5. Descriptive link labels: 0/2.5. Context beside file links: 0/2.5. Sampled destination accessibility: 0/10.
0 valid URL occurrence(s), 0 malformed, unsupported or unresolved.
0 unique destination(s) from 0 valid occurrence(s).
0 of 0 unique links have non-placeholder labels. This is a text heuristic, not a semantic guarantee.
0 of 0 unique links have notes beside a Markdown list link.
No documentation links were available to check; no link-health points earned.
How to improve: Use unique HTTP(S) documentation links with descriptive labels and short notes beside list links. Fix confirmed HTTP 404/410 destinations in the sample below. Access-denied, rate-limited or timed-out checks are unknown, not confirmed broken. Request a recheck after changes; more links alone earn no extra points.
Age of last successful verification: 10/10. Latest primary check succeeded: 5/5.
Last success: 2026-11-10T22:27:31.294Z. Full points through day 8 (7-day schedule plus 1-day grace), 60% through day 30, 20% thereafter or for an unknown date.
Latest primary verification succeeded.
Useful summary blockquote: 0/5. Useful introductory context: 5/5.
A blockquote before the first H2 with at least 20 non-whitespace characters and no placeholder-only text.
An introductory paragraph before the first H2 with at least 20 non-whitespace characters and no placeholder-only text. Listing form fields do not earn these points.
How to improve: Add a useful > summary and a separate introductory paragraph before the first ## section in the file itself. Each must contain at least 20 non-whitespace characters and not consist only of placeholder text. Each earns five default points. Editing listing form fields alone does not improve this component.

Only HTTP 404/410 is classified as confirmed broken. HTTP 403/429, timeouts and incomplete checks remain unknown. If all sample outcomes are unknown, the link-health check is excluded from the assessed maximum and the score is marked provisional.
