About SubMan

SubMan is built by Thuc Mai, an IT project manager and product owner based in Ho Chi Minh City, Vietnam.

After years of delivering software for clients, Thuc started building SubMan in February 2026 to solve a problem he had himself: paying for more AI tools than he could keep track of. A chatbot here, an image tool there, a music generator, a voice tool. Each one a small charge, together a real cost.

SubMan brings every AI subscription into one place, shows what each tool actually costs per use, and reminds you before a renewal you meant to cancel. It is now in public beta and free to use.
