Document Summary & Finance Calculator

I want a browser-based application that lets me upload multiple documents—PDF, Word, or plain text—then automatically produces a concise summary for each one. The text-analysis portion is focused solely on document summarization; I don’t need sentiment or keyword work right now.

Once the summaries are generated, I need to run custom financial calculations. Think of a flexible formula builder where I can enter or select values (totals, averages, growth rates, etc.) and instantly see the results. I should be able to save, edit, and reuse these formulas without touching the code.

Key expectations
• Clean drag-and-drop interface for bulk upload
• Reliable text parsing that handles varied layouts
• NLP-powered summarizer (spaCy, transformers, or similar) with response times in seconds, not minutes
• Formula engine that supports typical financial operators, percentage math, multi-step expressions, and exports to CSV/Excel
• Clear architecture (e.g., Python/Django or Node/Express API with a React/Vue front end—open to your suggestion) and well-commented code

Acceptance criteria
1. Upload 20 mixed-format documents; each summary returns under 200 words with no crashes.
2. Create a multi-line financial formula, save it, and rerun it on new values without editing code.
3. Full project runs locally with a single command and deploys to a cloud host of my choice.

If this sounds within your wheelhouse, let me know what tech stack you’d propose and a rough timeline for an MVP.
