I use it daily:
1. doc writing/editing: dont expect final polished papers but given a structure bullet points and data, it will quickly get me up and running.
2. automation of repetitive tasks: my team dont need to wait for tech support for smaller tasks anymore. Probably one side effect is, I get several escalations related to security concerns. But we are establishing some guardrails to avoid those.
3. summarising long email threads: this could seem mundane but life saver for me given I need to answer lot of emails often with long threads...
