BankNarrator: parser for messy bank narrations

Turn chaotic Indian bank transaction descriptions into structured data

Problem

A HN Show HN presents a zero-dependency parser for chaotic Indian bank narrations. People doing personal bookkeeping or financial analysis export bank statements where transaction descriptions vary wildly and even differ across channels at the same bank, making automatic categorization and reporting painful and manual cleanup tedious.

Solution

An API and web tool that accepts uploaded or pasted bank statements, detects the bank, transaction type, merchant, amount, and date, and outputs structured JSON with category suggestions. Custom rules and feedback correction improve coverage across more bank formats.

Users

Personal finance users, fintech SaaS developers, freelancers handling statements

MVP

CSV/PDF statement upload; parse common bank formats; structured JSON output; basic categorization; custom rules

Revenue

Usage-based API pricing; web subscription at $5/mo; bulk license for fintech SaaS

Why now

India's digital payment growth creates huge statement data with low standardization; big companies avoid this dirty work, and an indie dev can build a moat through rule libraries and community feedback
