About Open AI Chat GPT features

I would appreciate if you could add the following features.

I would like to be able to summarize the contents of PDF and word files in other languages.

I would like to be able to summarize the contents of audio files in other languages.
Also, please support iphone file formats. (m4a)

Please maintain the ability to summarize long sentences. I don’t want the summarizing power to drop.

When summarizing URLs, the answers are not very detailed. I want ChatGPT to summarize in detail.
