Debanking complaint and case-tracking tool for consumers

What to build

A web app for individuals and small business owners who've had a bank account abruptly closed: a structured incident-logging form that uses AI to auto-draft a CFPB complaint and a bank demand letter from the user's details, then tracks the case status (filed, acknowledged, resolved) through to resolution.

The CFPB's new investigation into debanking at nine major banks will surface a wave of affected account holders who have no easy way to document their case or file a complaint — a lightweight case-tracking and complaint-drafting tool fills that gap immediately while the story is live.

Demand

Individuals and small business owners who've had accounts closed without explanation want a fast, low-cost way to file a CFPB complaint and press the bank for answers; demand spikes now because the investigation gives their complaints new regulatory weight and media attention.

Solo + AI difficulty

The CRUD form, case tracker, and AI letter-drafting are all straightforward to ship with AI coding assistance — a solo builder could have an MVP live in 1-2 weeks. The hard parts are legal: AI-drafted CFPB complaints and demand letters touch unauthorized-practice-of-law risk, so templates need disclaimers and likely legal review, and any aggregated pattern data raises privacy/liability questions that take real care, not just code.

Entry threshold

No license is needed for a complaint-documentation assistant (not legal advice), so a solo builder can ship an MVP with a form plus AI letter generation in one to two weeks; the real work is building a credible initial database of incidents and trust with affected communities.

Counter-signals & risks

• The CFPB's regulatory authority and enforcement priorities could shift or be curtailed due to leadership changes, litigation, or political pressure, reducing follow-through on the investigation and the urgency driving demand.

• Banks may attribute closures to legitimate compliance obligations (BSA/AML, sanctions screening) rather than discriminatory or arbitrary debanking, which would undermine the premise that there's widespread wrongdoing to document.

• A user-facing tracker aggregating financial dispute data and AI-drafting regulatory/legal complaints raises real data privacy, liability, and unauthorized-practice-of-law concerns that need to be addressed before launch, not after.
