A free web (and forthcoming iOS) text-to-speech app built with open-source TTS, generating audio server-side and offered with no paid tiers or limits.
Problem it solves. Provides a low-cost alternative to expensive TTS subscription apps by offering free, high-quality text-to-speech.
Who pays. People wanting affordable TTS (readers, students, accessibility users)
Market. consumer text-to-speech / accessibility
How it makes money. Currently none (free, no paid tiers); potential future paid tier or ads discussed
Author reports concrete usage and cost metrics (2,000 users, ~$50/month), describes technical choices (server-side generation, optimized TTS models, rate limiting) and answered community questions; commenters corroborate surprise at low hosting cost and discuss caching/limits rather than calling it fake or promotional.
