Resemble AI
Resemble AI started as a voice-cloning and text-to-speech platform and has expanded into 'generative AI security' -- it generates voices, watermarks them, and detects deepfakes across audio, image, and video. Pricing is transparent pay-as-you-go (TTS around $0.0005/sec, ~$1.80/hr) with credits that never expire, plus custom enterprise. There's no ongoing free tier, just initial credits to start. It open-sourced its Chatterbox TTS model (popular on Hugging Face), and its real differentiator is provenance and deepfake defense, not the cheapest narration.
Speechify
Speechify is the mainstream 'read anything aloud' assistant, claiming 55M+ users and topping the App Store's text-to-speech charts. The same engine is available as a developer TTS API (1,000+ voices, 60+ languages, instant voice cloning, SSML, streaming), so it spans consumers and builders. The free tier is deliberately thin -- 10 robotic voices, TTS-only -- and consumer Premium is $29/mo, while API pricing is signup-gated rather than public. Its edge is distribution and reach, not raw model novelty.
Resemble AI edges Speechify on aggregate — 82 vs 79.
A TTS-plus-security platform -- best when you need voice cloning AND provenance/deepfake defense, less so if you just want cheap bulk narration. Speechify still wins for buyers who prioritise 1,000+ voices across 60+ languages. Both tools are independently scored — the right pick depends on which dimensions matter most for your workflow.
