All this in just a few seconds! Yeah, this video sounds interesting, I should probably watch it! 😃
GenAI isn't just about quick analysis; it's about customization.
One of the best things is that it allows you to effortlessly increase or decrease the level of detail of a summary, similar to having zoom-in and zoom-out buttons but for the amount of information!
My favorite instruction when I want to quickly scan something is to say “Make it 5 words at maximum” or "Maximum 5 words per bullet point" and run it again:
msg = aigenerate(:AnalystChaptersInTranscript; transcript=txt, instructions="Maximum 2 bullet points per section or chapter. Maximum 5 words per bullet point.", model="gpt4t")[ Info: Tokens: 3729 @ Cost: \$0.0434 in 21.5 seconds

Of course, use it whenever you can! The benefits of using PromptingTools.jl are:
The full power of Julia REPL at your disposal (eg, chunk long documents, merge answers, scrub sensitive information)
Automate tasks, eg, "Summarize these 20 Youtube videos in my Watch Later list and save it as a nicely formatted Markdown file or a Quarto document"
Leverage intricate templates in PromptingTools.jl and placeholders in them (eg, just provide the transcript and we take care of the rest)
In less than a minute, you've analyzed the key messages and extracted their timestamps - that's ~10x timesaving compared to watching the entire video!
Stay tuned for more GenAI mini-task magic in upcoming posts, where we'll continue to explore practical, time-saving uses of Generative AI for everyday tasks. Happy coding and watching! 🚀📺
