What made me work on my extension?
I had to do online marketing with 0 budget. That is why I worked as a guerrilla online marketer. I inserted the url of the tool I wanted to advertise into blogpost comments and posts on Reddit and X etc. It worked well, but after a short while I had to realize that I could not remember of the sites where I left my comments.
2 problems
And forgetting site names and usrls was only one of the problems. The other is that my spelling was not perfect. So I needed a free tool that solves both of the problems. As I had no money, I had to build it myself.
How does it work?
- You save urls you want to log.
- You insert the comment into proofreading text area.
- The extension checks spelling.
- You correct the mistakes and save your comment on the clipboard.
- You paste your comment on a blog.
- The extension logs this movement.
- You can see where you pasted your urls.
- You can download your logs in json an csv format (and you can clear the log when you want).
How I built it
I vibe-coded the extension. I know some of javascript and I also know the structure of a chrome extension, but I need to be fast. So I was a human in the loop, but don't think it is simple. I used claude, chatgpt, grock and agent-zero. One corrects the error of the other. And you should know how to make different phases of the vibe-coding process.
Challenges I ran into
If you want to vibe-code a complex Chrome extension it is not a good strategy to tell everything to the tool to code. You must work as if you were real coder. If your extension is like a "bus", first you have to build a "bicycle", then a "car" and then a "bus". It is often said that vibe-coders can correct themselves. My experience is that vibe-coders can correct errors made by other coders.
Accomplishments that I am proud of
I did it as a sole founder. I could do it fast. It was like playing a game.
What I learned
The best way to use vibe-coders is using more than 1.
What's next for Tool for Guerrilla Online Marketers: Remembers & Proofreads
I hope that other guerrilla online marketing specialists will be able to use my tool soon. There are other guerrilla marketing task that can be automated. For this I should build a flask app. I can do it, but if once I do, I should build a SaaS so I could make money from subscription fees.
