How I Automated a Weekly AI News Blog Using RSS, Gemini, GitHub Actions, and Blogger with $0 cost

I wanted a simple, low-cost way to publish a weekly AI and platform engineering brief. The goal was clear: collect interesting updates from trusted RSS feeds, summarize them with Gemini, publish the result to Blogger, and generate a LinkedIn-ready share post.

The result is AI News in 10: Weekend Brief, an automated weekly blog pipeline that runs every Thursday at 5 PM Central time.

The idea

Instead of building a full newsletter platform or custom CMS, I used tools that are either free or already available:

  • RSS feeds for source discovery
  • Gemini API for summarization and blog generation
  • GitHub Actions for weekly automation
  • Blogger API for publishing to Blogspot
  • GitHub Actions Summary for the final blog link and LinkedIn copy

End-to-end flow

RSS sources

The feed list covers AI model vendors, agentic development, cloud-native engineering, CI/CD, and security. Some examples include:

  • OpenAI Blog
  • Anthropic Blog
  • Google AI Blog
  • xAI Blog
  • Hugging Face Blog
  • Kubernetes Blog
  • CNCF Blog
  • GitHub Blog
  • Simon Willison
  • The New Stack
  • InfoQ AI/ML
  • Snyk Blog

What Gemini does

Gemini does not browse the web directly in this workflow. Instead, the script gives Gemini a curated list of recent RSS items with titles, links, summaries, categories, and source names.

Gemini then creates a compact post using this structure:

  • This week’s AI pulse
  • Know this
  • Try this
  • Watch this
  • Bottom line
  • Sources

This keeps the post short, useful, and grounded in source links.

API integrations

The automation uses three main integrations:

  • Gemini API: turns selected source notes into a clean weekly blog post.
  • Blogger API: publishes the generated HTML directly to Blogspot.
  • GitHub Actions: runs the workflow on schedule and stores secrets securely.

The workflow uses GitHub Secrets for sensitive values like:

  • Gemini API key
  • Blogger Blog ID
  • Blogger OAuth Client ID
  • Blogger OAuth Client Secret
  • Blogger Refresh Token

Publishing flow

GitHub Actions
   |
   |-- GEMINI_API_KEY
   |-- BLOGGER_CLIENT_ID
   |-- BLOGGER_CLIENT_SECRET

   |
   v
Generate post
   |
   v
Publish to Blogger
   |
   v
Generate LinkedIn copy
   |
   v
Show everything in GitHub run summary

Why this approach works

  • Cheap: It runs on free or low-cost tools.
  • Simple: No custom server or CMS needed.
  • Repeatable: It runs every Thursday automatically.
  • Human-friendly: It creates short, actionable posts instead of long summaries.
  • Shareable: It also generates LinkedIn-ready text.

Final result

The system now produces a weekly AI brief automatically, publishes it to Blogspot, and gives me a ready-to-share LinkedIn post.

It is a small automation, but a useful one: a tiny publishing engine powered by RSS, Gemini, GitHub Actions, and Blogger.

I Built an AI That Reads 400 Repos and 22 RSS Feeds So I Don’t Have To

How a knowledge graph, two cron jobs, and an LLM replaced my morning routine Surya Jayanti · April 2026 I manage a platform with 400+ repositories across multiple GitHub orgs. Every morning used to mean: 30+ merged PRs releases I didn’t track wiki updates I missed 22 blogs worth of industry noise So I built three AI systems that read everything for me, analyze it against my codebase, and send a briefing before my first coffee. This is how it works. 1. The Knowledge Graph: Teaching an LLM Your Codebase LLMs are great generalists, but they don’t understand your platform. Ask them about your services and they’ll confidently hallucinate. I call this the hallucination gap . The fix: build a structured representation of your codebase. Why not just RAG? Chunk-and-embed gives you fragments. But real insights live between files : imports → dependencies Kafka producers → consumers service calls → system wiring So instead of dumping code, I extract relationships. 4-Layer Model ...

My spiritual journey - Dalai Lama

Reflections on Compassion and Commitment: Reading the Dalai Lama This is my second book by the Dalai Lama, and once again, I find myself deeply moved by his philosophy of compassion. It’s one thing to read about compassion — it’s another to live it, to embody it, as he has done throughout his life. His words are simple, but the practice he describes feels like climbing a mountain — difficult, humbling, and profoundly transformative. My first encounter with his writing was The Book of Joy , a beautiful dialogue between the Dalai Lama and Archbishop Desmond Tutu. That book opened my heart to the universality of kindness and joy, beyond religion or nationality. These two readings together have widened my spiritual horizons in ways I didn’t anticipate. The Three Commitments What struck me most in this book was the Dalai Lama’s three lifelong commitments : As a human being , one to promote human values such as compassion, forgiveness, tolerance, and self-discipline. As a Buddhist monk ...
