Marketers Saw These 5 AI Agents and Said: “Link Please?”

Yes, I built them. No, I didn’t expect this many DMs.

I didn’t plan to turn this into a full post.

But after getting more DMs, “link please?” replies, and good feedback, I decided to put everything here.

Especially for those who don’t follow me on LinkedIn.

These are 5 AI agents that I built myself.

They’ve saved me over 20 hours a week and helped one SME cut $1,000/month in manual ops.

Each one takes less than 20 minutes to set up.

Just a Little Social Proof…

So that you will read more :)

Enough proof? Let’s get into the agents.

AI Agent #1: AI News Summary

What it does:
Auto-scrapes the latest “AI marketing” news every morning
→ summarizes with Gemini
→ emails it to you

Why I built it:
I don’t have time to check the latest AI marketing news every day. And when I try, I miss important updates.

This agent pulls the latest news, summarises them, and sends them to my email in an easily digestible format.

Other use cases:
• Search “viral TikTok trends” on Google → summarise the latest news articles
→ Recreate the trend within 24 hours before it fades

• Search “B2B SaaS funding news” → summarise who raised and why
→ Identify and qualify new buyers based on funding stage and growth signals

AI Agent #2: New YouTube Video Summary

What it does:
Checks for new uploads from YouTube channels you follow
→ pulls the transcript
→ summarises the key points using GPT
→ sends a concise summary to your inbox

Why I built it:
Most YouTube videos are 45 minutes long. I don’t have time to sit through all that just to find one good insight. This agent gives me the takeaways without the watch time.

AI Agent #3 - Competitor Messaging Radar

What it does:
Monitors up to 7 competitor LinkedIn pages
→ pulls their latest posts
→ summarises weekly messaging trends into a bullet-style report

Also highlights 1–2 positioning gaps or narrative opportunities your brand can act on

Why I built it:
I wanted a faster way to see how our competitors are shifting their messaging without reading 35 posts.

This agent gives me a clear summary of what each brand is saying, how they’re positioning, and what we should watch out for.

Other use cases:
• Monitor emerging startups in your space to spot narrative shifts early
• Summarise your own company’s posts weekly for internal brand consistency
• Feed summaries into your sales team so they can adjust pitches or objection handling

AI Agent #4: Reddit RSS to Replies

What it does:
Monitors targeted subreddits via RSS
→ pulls the latest threads
→ filters for the top 5 posts you can meaningfully contribute to
→ writes short, relevant replies based on your expertise and bio

Each post comes with the title, link, and a draft response sent daily to your email, ready to copy and paste.

Why I built it:
Reddit is full of high-intent conversations but staying on top of them takes too much time.

This agent helps me show up early, add value, and build visibility… without checking Reddit every day.

Other use cases:
• Join founder, SaaS, or B2B subreddits to build authority and visibility
• Source questions from your ICP as potential content for your email, blog, or LinkedIn content
• Identify new pain points your ICP is talking about to test them as angles in your ads or landing pages

AI Agent #5: Reddit AI Marketing Agents Miner

What it does:
Scans r/AI_Agents and related subreddits for new threads about AI agents used in marketing
→ tags each one by category (ads, email, SEO, etc.)
→ summarises the core use case in under 100 words → updates everything into a Google Sheet.

Why I built it:
Reddit is one of the few places where AI builders share what they’re actually shipping.

I wanted a way to track high-signal marketing agent ideas without spending hours a day trying to keep up.

Template:

Other use cases:

Wrap Up: Start Small

Most people don’t need more tools. They need working systems.

If you’ve been on the sidelines, start small.

One useful agent is all it takes to change how you work.

I test AI workflows on real marketing problems.

And turn the useful ones into 10x Playbooks.

So business owners and solo marketers doing it all themselves can skip the guesswork… and copy what actually works.

→ I drop one of these 10xPlaybooks 🚀 every week, don’t miss the next.
