DeepL and Google Translate impose hard limits on the size of the pptx files that they accept, even in their paying plans. This makes pptx translation effectively impossible for office-like usage.
I developed slidelang to remove this limit, but most importantly to take advantage of gpt-based translation and build a modern service : enabling the user to control the style of the translation.
For instance, translating to "Spanish" or "French" is too vague, when these 2 languages have tons of regional variations. Now users can instruct the translator to adapt to these variations, with additional stylistic instructions if they want ("formal", "business like", "for a young audience"... you freely type it).
Try this app and let me know what features would be useful to you?
NB: the app is entirely built with Java, back and front.
