Most social teams brainstorm content ideas from memory or a generic AI prompt, then wonder why nothing sounds different from a competitor’s post. Christopher Penn, Chief Data Scientist at TrustInsights.ai, pulls real audience questions straight out of Reddit and turns them into a ranked list of 100 video topics.

In this episode:

A model on par with Claude Sonnet 5 can run for about 1/40th the cost through a smart-and-cheap provider pick.

Reddit’s questions, not its answers, make the safest source material, with a human still filtering trolls and skipping competitor mentions.

One Gemini Notebook prompt turns a raw Reddit export into 100 ranked questions.

Recording on an iPhone in a kitchen can beat a polished studio setup on platforms downranking synthetic-looking video.

Turning on YouTube’s third-party training permission gets a creator’s expertise cited by AI agents.
