The Story

Why I Built This

Summer 2025. I'm interning at Stotan Industrial, and stretched with a lot of work. Live deals, memo preparations, market research and my most tedious tasks: data input.

Since Q2 Broker reports were coming out in a few weeks, I was motivated to find a way to automate this tedious task of transposing each data point into our internal spreadsheets.

I thought: What if I could leverage AI to structure an output that was just like our internal files? Something that preserved our exact template and column structure, not just raw JSON.

So I built it myself – nights and weekends. Three weeks later, I had an MVP. Six more weeks of iterations, and Claro Comps was running smoothly.

How It Works

Upload your template once, and your excel format is automated forever.

The insight: AI already reads PDFs well. The bottleneck was structure.

I built a template engine that learns your exact column structure once, then applies it forever, with any document you upload.

I saw a problem consuming hours of valuable time. Three weeks later, I had an MVP. A few more weeks of iterations, and I had a solid solution.

Not perfect, but functional. Not a company, but proof that when you see inefficiency, you can just build a solution.
