What they are
Speechify
Speechify converts text from PDFs, articles, emails, Google Docs, and ebooks into spoken audio using AI-generated voices. It is used by students, professionals, and people with dyslexia or reading difficulties who want to consume written content faster or more comfortably. The voice quality is genuinely good at normal speeds, but at very high playback rates naturalness degrades noticeably. The free tier is limited to one standard voice and a capped speed.
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.
