How to use this text tool

  1. Paste text or choose a plain-text file.
  2. Set only the options that apply to your content.
  3. Select Run Accessible Error Message Checker or press Ctrl/Cmd + Enter.
  4. Review every flag or change in its original context before publishing.

What this tool does

This page applies focused, explainable checks or formatting rules to the text you provide. The output is meant to support an accessibility review, not replace testing with disabled people and assistive technology.

The tool uses local pattern matching, text measurement, and the options shown above. It does not send your text to an external language model or silently change the source file.

Treat automatic suggestions as editorial prompts. Preserve meaning, respect self-identification, and follow the accessibility requirements of the platform where the text will appear.

Example

Load the sample to see a realistic input for the accessible error message checker. Run it once with the defaults, then change an option and compare the visible report and downloadable data.

Use cases

  • Review content before a website or app release.
  • Prepare subtitles, documents, forms, or interface copy for an accessibility audit.
  • Give editors a concrete list of passages that need human judgment.
  • Export a small review record for collaboration.

Tips for better output

  • Keep a copy of the original before accepting changes.
  • Read each result in the surrounding paragraph or interface.
  • Test with the assistive technology used by your audience.
  • Prefer specific wording over automatic one-for-one substitutions.
  • Ask affected readers for feedback when a choice is uncertain.

Processing details

All analysis runs in this browser tab. Unicode-aware matching is used where practical, and results can be copied or exported as text, CSV, or JSON when structured findings are available.

No automated checker can understand every cultural, linguistic, technical, or personal context. The built-in rules are intentionally conservative and the final decision remains with the editor.

Frequently asked questions

What makes an error message accessible?

It identifies the affected field or action, explains the requirement in plain language, and gives a practical recovery step.

Can an error message refer to a red border?

Color may support the message but should not be the only locator. Name the field and connect the message programmatically to its input.

Does this checker test ARIA attributes or focus movement?

No. It reviews message wording only. You must separately test labels, aria-describedby connections, live regions, and focus behavior.

Why are technical error codes flagged?

Codes can help support teams, but users also need a plain-language explanation and a next step.

Does a high score prove the form is accessible?

No. The score only reflects patterns in the submitted wording and cannot evaluate the surrounding form or user flow.
