Every option in the catalog for when you need to turn text into a natural-sounding voice — 36 AI voice and text-to-speech tools, 34 of them free or freemium, with the pricing tier printed on every row.
Flocci AI Tools lists 36 of them, ordered free tiers first: Copilot Audio Expressions, Kokoro Web, Zonos, Chatterbox (Resemble AI) and CosyVoice. 34 of the 36 are free or have a free tier. Each entry states what it uniquely does rather than a score.
24 on this page are marked fully free with no paid plan at all: Copilot Audio Expressions, Kokoro Web, Zonos, Chatterbox (Resemble AI) and CosyVoice. The remaining 12 are freemium, trial or paid, and each is labelled with its exact tier so nothing surprises you at sign-up.
Free tools first, then freemium, then trial, then paid, and alphabetically inside each tier. Nobody pays to appear higher: Flocci AI Tools carries no ads, no sponsored slots and no paid listings, so the order reflects price and nothing else.
Copilot Audio Expressions, Kokoro Web, Zonos, CAMB.AI and Cartesia all work in a browser tab with no install needed — just open the site and go. 12 of the 34 free AI voice and text-to-speech tools listed here are browser-based.
Speechify and Krisp have an iOS or Android app. 2 of the 34 free AI voice and text-to-speech tools here can run on your phone.
