Typestamp - Human content verification tool for social media

Published Mar 23, 2026

🔴 Problem Identified

Social media platforms like Reddit are increasingly flooded with AI-generated content, making it difficult to find authentic human-written posts and comments. Users want to distinguish genuine human discourse from automated content, but currently have no reliable way to verify authorship.

💡 Proposed Solution

A browser tool that tracks keystrokes with timestamps while users write content, encrypts this data with the final text, and generates a verification link. The proof shows writing patterns like cadence, pauses, and hesitations that are characteristic of human writing, making it difficult to fake cost-effectively.
