What they are
Playground AI
Playground AI is a web-based image generation and graphic design platform that combines text-to-image generation with a canvas-style editor, templates, background removal, and upscaling. It runs multiple AI models including GPT Image 2, Nano Banana Pro, and Seedream, making it useful for social media graphics, merch designs, logos, and product mockups. Creators in the print-on-demand and crafting space are among its most active users. Unlike pure generators, it leans toward practical design output over artistic experimentation.
Substack
Substack is a publishing platform where writers host email newsletters and charge subscribers a recurring fee. Independent journalists, essayists, and niche experts use it to build direct audiences without relying on ad revenue. The platform handles payments, delivery, and a basic website automatically. Substack takes a 10% cut of paid subscription revenue on top of stripe fees, which becomes a real cost as an audience grows.
