What they are
Captions
AI-first video editor focused on short-form content for TikTok, Reels, and Shorts. Automatic captions, eye-contact correction, AI avatars, and one-tap video creation from a script.
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.
