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.
Sudowrite
Sudowrite is an AI writing assistant designed for novelists, short story writers, and screenwriters who need help developing plot, prose, and characters. It offers specialized tools like Story Engine for structured novel drafting, Describe for sensory scene details, and Brainstorm for unstuck moments. Unlike general-purpose AI writers, it is tuned for creative fiction rather than marketing copy. The tradeoff is that it is narrowly focused, so non-fiction and content creators will find limited utility here.
