Grammarly

Grammarly, an AI-powered writing assistant, operates in a massive and growing market, demonstrating high user willingness to pay for its core services. Despite its popularity and strong positive feedback for real-time corrections and ease of use, systemic issues like inaccurate suggestions, billing problems, poor customer support, and integration challenges create significant pain points for users. These weaknesses in a crowded market present opportunities for indie hackers to develop specialized or more user-centric digital solutions.
