What are the best use cases of AI you've found so far, or where has AI made the biggest difference in your daily work?

Improving the productivity and efficiency on software development lifecycle.

I use Gemini in Google Drive to query the last 30 days of meeting notes content for a particular initiative that has weekly meeting. I have Gemini summarize key discussion topics and action items so that I have a centralized list of action items for the recurring meeting and context on progress for the month.

I use microsoft copilot to summarise all my unread emails n suggest what actions to be taken for those urgent ones requiring my attention. Super handy!

The lowest barrier to entry is using AI to help your writing and to remove writer's block.  It is so useful to ensure you don't have "attitude" in your writing and target the tone and voice for the intended audience.  The second easy use case is meeting notes summarized with AI.  The third is loading several doc in and using AI to summarize it.  My next step is to build some automation with an agent. 

Extracting data from faxes and loading the data into the enterprise system, structuring unstructed data, content development, webpage mockups using Lovable for sure, and being able to understand language (act as a medical doctor with 25 years of experience...does this physician note indicate the patient has osteoarthritis?)
