- people are harping on bias, but I think they miss the point. Use the tool, get the tool result, and let god sort them out.
- Multilingual sources are core to the value proposition. Make it a community list with tags, e.g: a user from india add their favourite local UP political news source with tags [india] [politics]. then you can taylor the reports by interests (yes, like all news aggregation websites before. they do it because it's needed I think)
- likewise,store the summaries, then enable users to ask for a rewighing with their interests in the prompt, e.g: "I am a well educated, religious Emirati interested mainly in news about the wars and tensions in the middlke east, as well as car racing"
- get news by actual news, not by news source. E.g: get the embeddings of the news, cluster, get summarization of "best" sources of cluster with added info like likely primary source, histograms of reputation vs sentiment vs political leaning
- todays news give you also access to the comments, both on the site and e.g: on reddit and twitter. add maybe a comment summarization / sentiment analysis (e.g: 90% of comments on this new york post article were racist one-liners. Dicscusion on this Korean article revolve around effects on workforce mental health, etc)
- you mention cost: make accounts able to add their ChatGPT API keys, with an estimation of how much you'll use, ang keep these accounts free. For the others, warn that in time you'll add a small charge maybe?
