CreditFix AI: Democratizing Credit JusticeInspirationIn 2026, credit report errors remain the #1 consumer complaint in the US. Most people can't afford a lawyer to fix a simple $100$ point drop caused by a clerical error.

I was inspired to build a tool that puts the power of the Fair Credit Reporting Act (FCRA) directly into the hands of the consumer, making credit repair as easy as taking a photo.How I Built ItThe project was built on a 15-day sprint using a lean, high-impact stack:Frontend/Backend: Next.js for a seamless, secure user experience.

The Brain (AI): I leveraged MeDo to architect a specialized legal reasoning engine. Instead of complex API integrations, the system uses OCR (Optical Character Recognition) to read user-uploaded PDFs or screenshots.

Logic: The AI acts as a digital paralegal, scanning for discrepancies such as:Incorrect late paymentsIdentity theft indicatorsExpired debts (Statute of Limitations)The Math of Credit ImpactCredit scores aren't just numbers; they are calculated through complex algorithms.

Correcting a single "Charge-off" error can impact a score significantly. If $S$ is the current score and $\Delta$ is the weight of the error, our goal is to maximize:$$S_{new} = S_{current} + \sum_{i=1}^{n} \Delta_{i}$$ Where $n$ is the number of successfully disputed items.Challenges I FacedData Privacy: Handling sensitive financial data required a "privacy-first" approach.

I implemented in-memory processing to ensure no SSNs are stored permanently on the server.

Legal Precision: Prompt engineering was the hardest part. I had to ensure the AI didn't just "chat," but cited specific sections like FCRA § 611 to ensure the credit bureaus take the dispute letters seriously.What I LearnedI learned that speed-to-market is better than feature bloat.

By focusing on a "Document-In, Letter-Out" flow, I created a functional MVP that solves a real-world problem without the bureaucracy of 3rd party credit integrations.

MeDo was essential in pivoting from a complex idea to a 15-day executable reality.
