I’ve used it to write out 45 minute long lesson plans, help write complicated text message where all I’ve got is a bunch of points to make, I’ve had it correct my Portuguese since I’m not a native speaker, I’ve had it give me a baseline SQL table design to achieve a specific goal, I’ve had it come up with different ways to phrase things since I’m not creative enough, I’ve had it write marketing copy, created design briefs for my graphic design team, and on… I happily pay for it because it’s just nuts how much of a force multiplier it is for me.
