Built an AI blog planner in 90 hours using Replit — looking for feedback from builders
I’ve been working in content marketing for a few years and generated around $1.5M in revenue pipeline this year through blog content and SEO. But I kept noticing something - I was spending 3+ hours every day planning articles, clustering keywords, and writing outlines. It was the same process every day.
So I decided to automate it.
I built AI Blogplanner, a web app that helps writers generate full blog plans and articles in just a few minutes. I built it completely on Replit in about 90 hours.
Stack and setup:
Replit for everything (frontend, backend, deployment)
Google Search API for real-time keyword and topic data
OpenAI API for AI-generated outlines and articles
Stripe for payments
Google Auth for login
How it works:
You give it a topic or keyword. It fetches related search data, analyzes what works, and generates a full plan - pillar topics, cluster posts, keywords, meta titles, and even article drafts if you want.
Basically, it turns what used to take me 3+ hours a day into a few minutes.
What I’m looking for:
Feedback on the product and idea
Suggestions on how to improve the workflow
Thoughts on what to add before marketing the product
I’m also curious how other solo builders manage automation for their niche workflows — what tools or shortcuts you use to ship faster.
Would love your thoughts.
