()Text inside square brackets

Toggle each option on or off as needed.
AI Filter (PDF)
This tool uses layout-based AI to identify and optionally skip structural elements within uploaded documents:
Header/Footer/Footnotes – skip running headers, footnotes, and repeated footers
Figure – skip figures or images
Figure Caption – skip captions related to images or figures
Table – skip tables, charts, and graphs
Table Caption – skip captions for tables, charts, or graphs
Formula – skip mathematical formulas
These filters are especially useful for academic papers, research articles, or slides.
Margins (PDF)
If you’re still getting unwanted text read aloud, you can manually define reading margins.
Set custom margins (top, bottom, left, right) as percentages.
Text outside the defined margins will not be read.
If adjusting margins alone doesn't work, click Try margins with OCR (requires subscription). This will:
Use OCR to capture a snapshot of the page.
Let you choose a page range (up to 50 pages).
Re-convert only the content within your specified margins.
This method helps exclude decorative content or complex layouts that regular detection might miss.
