BankFight: Fraud Dispute Letter Generator & Tracker

fraud disputeconsumer financebankinglegal letters

The Problem

A viral r/personalfinance post (2,255 upvotes) detailed how a traveler had a $1,500 Wells Fargo fraud claim denied and had to fight back manually — a process most people don't know how to navigate. BankFight generates legally-informed dispute letters tailored to the specific bank and fraud type, tracks deadlines (Reg E, FCBA), and sends escalation reminders so users don't miss the window to appeal. It turns a confusing, high-stakes process into a guided workflow.

Target Audience

US consumers who have experienced bank fraud or unauthorized charges and received a denial or partial resolution from their bank

Monetization Angle

$4.99 one-time per dispute case; optional $2.99/mo for unlimited cases and deadline tracking across multiple accounts

Evidence & Source Signal

Reddit: Contactless payment fraud is rising sharply post-pandemic, and banks are increasingly denying first-round claims — the r/personalfinance post hit 2k+ upvotes because this is a universal, recurring pain.

Why Now

Contactless payment fraud is rising sharply post-pandemic, and banks are increasingly denying first-round claims — the r/personalfinance post hit 2k+ upvotes because this is a universal, recurring pain.

MVP Scope

A 5-step form collecting fraud details and bank name, outputting a formatted Regulation E dispute letter as a PDF with a deadline calendar reminder.

AI Angle

AI personalizes the dispute letter using the specific fraud scenario, bank name, and transaction details, referencing the correct federal regulation (Reg E for debit, FCBA for credit) automatically.

Primary Risk

Not legal advice disclaimers must be prominent; risk of users expecting guaranteed outcomes — must set expectations clearly to avoid chargebacks on the product itself.
