The Problem
The internet is a chaotic, noisy place. For founders, creators, marketers, and investors, keeping up with emerging trends across industries like AI, health tech, or the creator economy takes hours of skimming blogs, newsletters, Substacks, Twitter, and podcasts.
Even then, you risk missing critical shifts or wasting time on shallow content. There’s no simple way to stay informed, organized, and proactive—without burning out.
The Solution: TrendSage
TrendSage is an AI agent that browses the web for you, discovers the latest trends in your chosen domain, and compiles them into shareable, organized content across multiple platforms.
It’s like having your own AI-powered market research assistant that delivers clarity without the noise.
What I Built
TrendSage is a Runner H agent that automates the entire market trend discovery and delivery workflow:
Web Research – It browses the internet and finds 3–5 real emerging trends in your chosen category.
Google Doc Report – It generates a structured, professional market brief with summaries and examples.
Google Sheets Table – It creates a table of key takeaways for quick scanning or internal use.
Gmail Digest – It sends a summary of the findings to your inbox.
Slack Message – It posts a quick summary into your Slack workspace for async team awareness.
PDF Recap – It wraps it all up in a downloadable PDF for sharing or archiving.

➤ `TrendSage Report – [Today's Date]`
Format it professionally using:
* A clear headline for each trend
* Bullet points for “What it is” and “Why it matters”
* Hyperlinked sources
* Optional intro paragraph: “This week’s trend roundup...”
4. **Create a Summary Sheet**
Create a **Google Sheet** titled:
