A python tool to check style errors in subtitles and captions. Guidelines are taken from (https://translationjournal.net/journal/04stndrd.htm) and (https://www.bbc.co.uk/accessibility/forproducts/guides/subtitles).
The checks this tool makes are aimed at English language captions and subtitles. Best practices for other languages may vary.
Automated checks can only catch so many issues.
