Anonymous Post Identity Exposure Risk Scanner

Step 1 Large-scale LLM-based de-anonymization technology

Step 2 Identity protection needs of online anonymous activists/whistleblowers
→
Step 3 Pre-publication identity exposure risk assessment for anonymous posts

Problem

Freelancers, corporate whistleblowers, and side-business operators who post anonymously on blogs and forums face rapidly growing risks of being identified through LLM-based writing pattern analysis. There is no way to self-assess how similar an anonymous post's writing style is to one's other accounts before publishing, leading to identity exposure followed by legal and social consequences (termination, lawsuits) discovered only after the fact. A single de-anonymization incident can threaten an entire career, making preventive measures highly valuable.

Solution

Before posting, users paste their text to receive: (1) writing fingerprint analysis (vocabulary frequency, sentence structure, distinctive expressions), (2) similarity score against their registered 'public account' writings, and (3) high-risk expression highlighting with paraphrasing suggestions. The key differentiator is deployment as a local browser extension where data never leaves the user's device.

Target: IT industry workers (ages 20-40) who are active users of anonymous communities (Blind, Clien, etc.), freelancers running side businesses
Revenue Model: Premium browser extension at $3.65/month per account, free tier limited to 5 analyses per month, 20% discount for annual billing
Ecosystem Role: Infrastructure
MVP Estimate: 2_weeks
