I added yesterday a simple OpenAI integration to Matcha RSS Reader so it can summarise RSS articles using GPT-3. Apparently, if you end the prompt with Tl;dr, it will summarise given text.

I think it could be a useful feature when you just want to know the gist of something (like in a news article) or help you decide whether to click an article when the title is a bit cryptic.

More details on how to enable this feature are found in the Readme of the project.
