A worker in their 50s subscribes to AI services like ChatGPT Plus, Copilot, Midjourney, and Naver Clova out of curiosity, but on average 1.5 services are used 2-3 times or less per month. Combined with existing digital subscriptions (Netflix, YouTube Premium, cloud storage, etc.), 50,000-150,000 KRW (approximately $37-$112) is auto-charged monthly, but it's hard to track which card is charged how much. AI services are especially difficult to manage because they are billed in dollars and amounts fluctuate with exchange rates.
Enter card payment details (via text or screenshot) to automatically categorize subscription services, calculate each service's 'cost vs. actual usage frequency,' and recommend cancellation priority. Provide free alternatives for each AI service (free tiers, open-source options) and step-by-step cancellation guides.
