Proofread with your ears.
Listening to what you have written is the best proofreading there is: a sentence you cannot say out loud does not hold up in writing either. Yappy reads .docx, .odt, .rtf, .txt and Markdown, with their headings and their rhythm.
In three steps.
1 Open the document Drag it into the desktop window or share it from your phone.
2 Listen paragraph by paragraph The text lights up as it is spoken; tap anywhere to jump.
3 Fix what grates Then listen again. On the computer, each paragraph can have its own voice and speed.

Spreadsheets and slides too
It reads .pptx, .xlsx and .csv. On the computer, if you have pandoc installed, the list grows to LaTeX, reStructuredText, Org and a few more.
Questions about this
Which text formats does it read exactly?
.docx, .odt, .rtf, .txt and Markdown, plus .pptx, .xlsx and .csv. On the computer, if you have pandoc installed, the list grows to LaTeX, reStructuredText, Org and a few more.
Does it read footnotes and tables too?
It reads the body of the document with its headings and its order. Tables are read row by row, which is the only thing anyone can do with a table out loud, and notes land at the end of their section rather than interrupting a sentence halfway.
Can I give each paragraph a different voice?
On the computer, yes: the paragraph editor lets you assign a voice, a speed and a pause to each one. It is what makes a dialogue, an interview or a bilingual document listenable.
Is it actually useful for proofreading?
It is the best proofreading there is. Listening exposes what the eye forgives: the word repeated three lines down, the clause that never closes, the aside that has swallowed the verb. Drop to 0.9×, listen to the chapter, and note down whatever grates.
