DisputePress is a free, open-source web application that helps you dispute a debt you believe is fraudulent. It reads the collection notice, shows you what it found, and prepares dispute letters for Equifax, Experian, TransUnion, and the creditor or debt collector. It runs entirely in your browser. ### How much does it cost? Nothing. DisputePress is free and open source under the AGPL license. There is no paid tier and no account. It is funded by donations. ### Is my personal information uploaded anywhere? No. Your documents, identity details and letters stay in your browser on your own computer. There is no server, no account, no analytics and no AI service. After the first visit the app works offline. ### Which letters can it write? Credit bureau dispute letters under the Fair Credit Reporting Act (FCRA), debt validation requests to debt collectors, an identity-theft declaration, and FCRA §605B identity-theft block requests. Output is a printable PDF or email-ready text. ### What kinds of notices can it read? Digital PDFs, scanned PDFs, `.eml` email files, and email text pasted in. Paper letters need to be scanned to PDF first. Password-protected PDFs and handwriting are not supported; you can enter values by hand instead. ### Does it use AI to write the letters? No. Values are found by deterministic pattern matching, and letters are fixed templates filled only with values you confirmed. Nothing is invented, and nothing unconfirmed reaches a letter. ### Is this legal advice? No. DisputePress is a document preparation tool. You are the sender of the letters and responsible for what they say. Deadlines it shows are general timeframes based on the dates you enter.
