A little more about the Google add-on.
Text to speech, Translate, Text settings, Text statistics, and the Google Docs Accessibility check work without a Pro key. Immersive Reader supports up to 1,200 characters per selection for free. Connect Helperbird Pro in Settings for longer selections.
The add-on brings selected Helperbird tools into Google Workspace. Page tools such as reading rulers, color overlays, and auto-scroll are in the Helperbird browser extension. Word prediction and grammar support are also extension features; they are not part of this add-on.
It offers reading suggestions in Google Docs and leaves edits to you. Its four checks do not cover every accessibility need. Review image descriptions, contrast, and reading order separately.
Sheets translation replaces only text cells in your selection. Formulas, numbers, dates, checkboxes, and empty cells are skipped. The preview shows a skipped-cell count so you can review it before replacing.
Sheets gives add-ons the selected cells, including all their text. Load the cell into Text to speech, highlight the words you want in its text box, and press Play.
Your administrator may need to approve or install the add-on. Start with the installation guide, or contact Helperbird support for help.
