Need to make a complaint, write an appeal, request a refund, or explain a problem clearly? Untangle is an AI-powered letter writer and document writing tool that helps you turn what happened into a clear, professional response. Whether you need to contact customer support, write a complaint letter, request a refund, appeal a decision, send a professional email, or simply don't know what to say, Untangle helps you work through the situation step by step and create the document or letter you need. Explain your situation Tell Untangle what happened in your own words. A guided interview helps you work through the important details and organizes your answers into a structured case. Organize the important details Untangle brings together your story, the people involved, important events, timeline, evidence, and other relevant information so you can understand your situation more clearly. Review your evidence Upload supporting documents and images related to your situation. Untangle uses AI to analyze your evidence and identify important information, including: • Key facts • People and parties involved • Important dates and timeline events • Financial information • Impacts and consequences • Supporting evidence • Uncertainties • Potential contradictions Instead of working through scattered information on your own, you can review the important details of your situation in one organized view. Create the letter or document you need Once your situation and evidence are organized, Untangle can generate a professional document based on the information you've provided. Depending on your situation, you can create: • Complaint letters • Appeal letters • Refund requests • Professional emails • Customer support responses • Other professional requests The AI writing assistant uses your case information and supporting evidence to help create a clear, structured response that explains what happened. An AI letter writer built around your situation Unlike a basic letter writer where you start with a blank page, Untangle first helps you organize the situation behind the letter or document. You can explain what happened, review your evidence, understand the important findings, and then create a professional response based on the information you've provided. From problem to response Untangle takes you from explaining what happened, to organizing the details, reviewing your evidence, understanding key findings, and creating the letter or document you need. When you're staring at a blank page and don't know where to start, Untangle gives you a structured way to work through the problem and turn your situation into a clear response. Organize your situation. Understand your evidence. Create a clear response. Untangle provides AI-powered organization, evidence analysis, and document generation. It does not replace professional legal, financial, medical, or other specialized advice.
