## What we know about KittenTTS

KittenTTS is a text-to-speech apis platform: the lightweight/edge option: ONNX inference, sub-100 MB downloads, 8 built-in voices - trades voice cloning and multilinguality for footprint. This profile tracks every KittenTTS fact we have verified, each linked to a primary source and dated.

KittenTTS does not publish a public per-minute rate we have been able to verify, so the price figure here stays blank until we can confirm one. We would rather show nothing than a guessed number; if you have a current KittenTTS quote, it is the fastest way for us to close that gap.

On capabilities, KittenTTS covers self-host / on-prem option, and does not offer instant voice cloning. Each of those is verified against KittenTTS's own docs or dashboard, not marketing copy.

Placed against the 46 text-to-speech tools we track, KittenTTS's strongest showing is the 43rd-widest language coverage - a spread worth weighing against your own priorities.

In total we track 9 verified facts for KittenTTS today, each linking the primary source it came from so you can check our work - and vendor claims we have not measured ourselves are labeled as such on the KittenTTS fact sheet below.
