Last week's excitement was the announcement that OpenAI allows you to build custom GPT apps. Now you can create a GPT that supports a narrow use case, and you provide it with detailed instructions, up to 10 documents or API links to give it background information. Then the GPT can produce far better results. These GPT apps can be private - so you can use them for personal productivity - or public so everyone can benefit.  

Already the Salesforce ecosystem has started building and publishing them.  So we built a directory http://SFGPTlist.com to make it easy to find them. But we've also made it so the creators of the GPTs can provide a list of prompts that work well with their GPT app. Not many have yet, but it is still very early days and the potential is HUGE. 

BTW You need to be on the GPT-Plus plan to build and use the custom GPTs.   

Not on the GPT-plus plan?  You can also use http://SFGPTlist.com to store personal prompts that you use regularly with standard OpenAI, Claude or Bard.
