We collect first the links and dates of each post before extracting the newest ones.\n\nThe result is sent to a SQL database, in this case a NocoDB database.\n\nThis process happens each week thru a cron job.\n\n**Requirements**:\n- Basic understanding of CSS selectors and how to get them via browser (usually: right click → inspect)\n- ChatGPT API account - normal account is not sufficient\n- A NocoDB database - of course you may choose any type of output target\n\n**Assumptions**:\n- CSS selectors work on the news site\n- The post has a date with own CSS selector - meaning date is not part of the news content\n\n**\"Warnings\"**\n- Not every site likes to be scraped, especially not in high frequency\n- Each website is structured in different ways, the workflow may then need several adaptations.\n\n\nHappy about any suggestion to improve. You may contact me on **Mastodon**: https://bonn.social/@askans"
