Budget Cells

A friend runs a construction company and I watched him painfully copying line items from architect PDFs to his invoicing system (with a 256 character limit per field).

5 years ago I built text-to-cells to help. He's been using it ever since, and it's saved hundreds of hours. But it crashes sometimes and I saw many ways to improve it.

Now with more experience, I decided to rebuild it properly. Budget Cells uses AI to automatically extract budget line items from PDFs and lets you copy any piece of data with one click.

What it does

• Upload construction budget PDFs
• AI extracts all line items (descriptions, quantities, prices, totals)
• Smart text chunking that respects sentence structure
• One-click copying to clipboard
• Tracks AI costs so you know what you're spending
• Works offline and everything is stored locally

Tech Stack

• SvelteKit 5 with TypeScript
• Tailwind CSS + shadcn-inspired design
• Google Gemini AI for text extraction
• PDF.js for client-side PDF processing
• IndexedDB for local storage

Setup

# Install
pnpm install
pnpm run dev

# Get a Gemini API key from https://makersuite.google.com/app/apikey
# Add it in the app settings

Why rebuild?

The original text-to-cells worked but had issues:

• Manual PDF copy/paste
• Basic UI

Budget Cells fixes all of this with AI automation, better architecture, and a professional interface.

Interface

The app is in Spanish since it's built for Spanish construction professionals, but the code and documentation are in English.
