Free tools for Google Docs, Slides, and Sheets.


Make yourself at home in
Google DocsGoogle SlidesGoogle SheetsReading tools
A long document. A new idea. A passage you want to hear again. Give yourself another way to read it.
Hear your selected text with your browser’s voices. Choose a voice, set the pace, and listen. You can also edit the text box or highlight just the words you want to hear.
Open selected text in Microsoft’s Immersive Reader for read aloud, line focus, and reading preferences.
Up to 1,200 characters per selection free. Pro supports longer selections.

Writing tools
Hear how a draft sounds, explore a translation, and check the shape of your writing before you share it.
Compare the original and translated text in a preview. Replace your selection when you’re ready, or use Translate & replace in one step. Review the result and formatting afterward.
Check word count, estimated reading time, and other useful measures. Change your selection and choose Recheck to take another look.
Use Text to speech as a fresh way to review your writing. Listen for a missing word or a sentence you’d like to change.


Accessibility tools
Make text comfortable for yourself, and review details that can make your document easier for someone else to read.
Choose fonts including Lexend and Atkinson Hyperlegible. Adjust text size and spacing in Docs and Slides, or cell layout and wrapping in Sheets.
Review your whole document, across all tabs, for small text, vague links, extended capitals, and long paragraphs. See suggestions with locations, then decide what to change.
These four checks are reading suggestions, not a complete accessibility audit. Review image descriptions, contrast, and reading order separately.

A few useful details
Find your tools, choose your settings, and get back to your words.
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.
