ThumbFlow AI

Hey everyone! I recently built ThumbFlow AI, an AI-powered tool that creates viral YouTube thumbnails in seconds. I'd like to share it with the HN community. *How it started:* As a solo maker, I kept seeing creators struggling with thumbnail creation - either spending hours learning design tools or paying $50+ for each thumbnail from freelancers. Most existing AI tools produce mediocre results that don't actually drive clicks.

ThumbFlow AI launched on August 14, 2025 with 13 votes, #983 of 8,530 launches that month and more than 75% of that year's launches.

    Hey HN! Software engineer here. As an amateur youtuber, I've been struggling with thumbnails, especially since I don't have any design or editing skills.
