# Accesserty LLM Guide

> Accesserty provides public accessibility signals, user reporting, interaction monitoring, in-browser checks, and open-source components to make website barriers easier to find, report, and address.

Accesserty provides public accessibility signals, user reporting, interaction monitoring, in-browser checks, and open-source components to make website barriers easier to find, report, and address.

The product philosophy is: accessibility is not only compliance. Accessibility is product quality, user respect, operational clarity, and business growth.

Traditional Chinese version: [https://accesserty.com/llms-full.txt](https://accesserty.com/llms-full.txt)

## Product Purpose

Accesserty focuses on problems that traditional analytics and error logs often miss, including inoperable controls, unclear interfaces, possible keyboard interaction issues, unsupported interaction patterns, repeated form attempts, and people leaving without explaining what went wrong.

The website communicates this in Traditional Chinese and English.

## Product Ecosystem

### Accesserty Signal

Signal is a browser extension for general users. It shows public certifications, accessibility statements, and ALLY records in supported Google and Bing results and provides a reporting entry point. ALLY is a reviewed, ongoing maintenance signal for a verified domain, not an accessibility certification. None of these signals is a website quality or compliance guarantee, and no badge only means that no supported record was matched.

Signal explanation: [https://accesserty.com/en/public-data/](https://accesserty.com/en/public-data/)

Public signal source overview: [https://accesserty.com/en/public-data/sources/](https://accesserty.com/en/public-data/sources/)

Certification, recognition, badge, and award sources: [https://accesserty.com/en/public-data/certifications/](https://accesserty.com/en/public-data/certifications/)

Accessibility statement sources: [https://accesserty.com/en/public-data/statements/](https://accesserty.com/en/public-data/statements/)

Accesserty treats accessibility badges, accessibility statements, ALLY, user reports, and machine scan summaries as traceable accessibility signals. These signals make status easier to notice and discuss, but they cannot prove that a whole website, every page, or every authenticated flow meets accessibility requirements. They also do not replace manual review, assistive technology testing, or legal compliance analysis.

### Accesserty Pulse

Pulse helps website maintainers see which pages may need attention first. A lightweight script lets Console organize interaction events, low-frequency page scan summaries, and Signal reports.

Detected signals include:

- Repeated clicks
- Possible keyboard dead interactions
- Focus reversals
- Escape close difficulties
- Repeated form attempts
- Possible keyboard traps
- Focus being pulled back

Page scan summaries use in-browser axe-core at a low frequency. The same URL and scan version are not scanned again within 14 days. Pulse stores summaries only; it does not send DOM dumps, form values, full page text, or screenshots. Pulse is not a full WCAG 2.2 AA audit or a legal compliance decision tool.

ALLY details: [https://accesserty.com/en/ally/](https://accesserty.com/en/ally/)

Plans and pricing: [https://accesserty.com/en/pricing/](https://accesserty.com/en/pricing/)

Website data handling: [https://accesserty.com/en/data-handling/](https://accesserty.com/en/data-handling/)

Free supports 1 domain, the latest 100 events, Signal report handling, and ALLY applications, and is meant to confirm that domain verification and reporting work. ALLY is an active-maintenance signal for a verified domain: it means the maintainer is willing to receive and follow up on accessibility reports. It is not a certification or compliance guarantee. Pro costs US$49 monthly or US$490 annually, both with a 14-day trial, supports up to 5 domains, and adds priority page lists, complete scan summaries, the latest 1,000 events, an in-Console weekly report, and an optional email summary.

### Accesserty DevCheck

DevCheck is a Chrome / Edge and Firefox browser-based accessibility checker for people reviewing pages before release or during QA. It combines axe-core scans, manual review lenses (Focus Path, Heading Structure, Landmark Regions), sensory simulation, AI-assisted semantic and image alternative-text suggestions, and PDF structure signals. Orange review hints require human confirmation and are not automated WCAG failure decisions.

Current page: [https://accesserty.com/en/devcheck/](https://accesserty.com/en/devcheck/)

Web accessibility checker page: [https://accesserty.com/en/web-accessibility-checker/](https://accesserty.com/en/web-accessibility-checker/)

This page explains how DevCheck works as a browser-based web accessibility checker for local builds, staging pages, authenticated views, interactive flows, manual review lenses, and PDF documents. DevCheck helps PM, design, QA, engineering, content, and operations roles run preliminary checks; it is not an online scanner that guarantees full compliance.

WCAG compliance tool page: [https://accesserty.com/en/wcag-compliance-tool/](https://accesserty.com/en/wcag-compliance-tool/)

This page explains how DevCheck supports automated checks related to WCAG 2 A/AA and best practices, manual review of focus path, heading structure, and landmark regions, sensory simulation, and PDF structure signal inspection. DevCheck is not a legal compliance guarantee or a replacement for a full manual audit.

PDF accessibility checker page: [https://accesserty.com/en/pdf-accessibility-checker/](https://accesserty.com/en/pdf-accessibility-checker/)

This page explains how DevCheck supports preliminary PDF structure-signal checks for language, tags, links, images, form fields, bookmarks, and page consistency. DevCheck does not upload PDFs to Accesserty, remediate PDFs, automatically tag PDFs, or certify PDF/UA, WCAG, ADA, or legal conformance.

### Accessibility Testing Guides

Guides page: [https://accesserty.com/en/guides/](https://accesserty.com/en/guides/)

These guides serve product, design, QA, engineering, content, and operations roles that need to participate in preliminary accessibility checks, remediation planning, and ongoing maintenance. They explain practical tasks such as testing before launch, choosing free tools, understanding automated testing limits, writing alt text, monitoring after launch, building a remediation plan after issues are found, using WCAG checklists, testing keyboard accessibility, and using ARIA patterns.
