Hey Allie,
Good question. Really depends what you're looking to optimise. Here are some of the things we've built/seen our clients build:
Basic 'GPT Projects' (or more advanced agents) that are very nuanced with the messaging & positioning, allowing them to create v1 of content quicker
Fathom.video > Notion integrations to ensure meeting actionable are logged in a database...
Opus.pro as an amazing tool to turn long form video content to short clips with engaging subtitles, identifying the most engaging part of the convo
Enabling team members to 'prompt correctly' with tailored guides for their business, sessions with their teams etc
(Not affiliated with any of the tools mentioned, just things we're using and finding really valuable)
Hope that's helpful, will add more if I think of anything else
