I shipped 14 free tools in 3 days with AI. What worked, what did not, and the numbers.
I run ARLing s. r. o. out of Bratislava. It's a one-person company: I'm 22, I can't write code, and most of what gets built is written by AI. Three days ago I decided to test how far that setup could go if I pushed it hard: pick real problems, ship free tools that fix them, and see what happens. This is not a growth story. After 48 hours the tools have a few dozen visitors each, no email signups,…
In a three-day span, entrepreneur ARLing (22) built 14 web tools using AI assistance. These tools address common errors in software development, including Expo and Supabase redirect problems, Flutter deep link issues, and SEPA payment file problems. Each tool was live within hours of conception, with the redirect checker for Expo and Supabase apps completing the build process in around 4 hours.
The tools were designed with a light, typographic layout featuring real screenshots and plain sentences, replacing the initial dark, generic AI output design which was deemed "AI slop." The entrepreneur observed that tools fixing one-time errors attract visitors but do not sustain traffic, as users have no reason to return once their issues are resolved.
The entrepreneur will focus on recurring problems, such as helping accountants with SEPA payment files and photographers with culling apps. The tools are hosted on the website arling.sk, with AI-generated code and pages built by AI agents, while the entrepreneur oversees distribution, analytics, and content creation.
