Overzicht
AccessFill checks the document, presentation or spreadsheet you have open against common accessibility guidelines such as WCAG 2.1, lists every issue it finds, and lets you fix most of them from the sidebar.

WHAT IT CHECKS
- Images without alt text, or with a file name such as IMG_2041 as their alt text.
- Headings: skipped levels, empty headings, and bold lines that look like headings but aren't.
- Link text such as "click here", and web addresses used as link text.
- Text colour contrast against its real background, including theme colours and table cells.
- Docs: typed bullets and numbers that should be a real list, very small text, an untitled document.
- Slides: missing, empty or repeated slide titles, and a title read after other items on the slide.
- Sheets: unfrozen header rows, merged cells, sheets still named Sheet1.

FIX IN PLACE
Go to jumps to each issue. Type the alt text or the new link text, pick the heading level, or take the nearest colour with enough contrast; AccessFill changes only that. With AccessFill unlocked, Fix all applies every fix that needs no typing in one go.

WHAT YOU CHECK BY HAND
Some things Google's editors don't let add-ons read or set, such as a Docs table's header row, alt text on wrapped images and on Sheets charts. AccessFill lists them for you to check yourself.

FREE CHECK, THEN $9 ONCE
The whole check is free, as often as you like. Five fixes are free in total per Google account, one at a time; then $9 once for unlimited fixes and Fix all, with no subscription. Refunds within 14 days.

AccessFill reaches only the file you open it in. It doesn't use AI and doesn't send your content anywhere.

AccessFill checks against common guidelines such as WCAG. It doesn't certify ADA or any other legal compliance, and passing its checks doesn't mean a file is fully accessible; a person still reviews the result.
