ReadAloud Studio: Listen & Summarize with Your AI de Mani

Listen to the web — powered by your own TTS server
Kokoro TTS web page reader turns articles, documentation, and long-form pages into natural speech using a Kokoro TTS API server you control. Point the extension at your local machine or a remote server, pick a voice, and listen while you browse, commute, or rest your eyes.

No subscription. No cloud TTS lock-in. Your audio is generated by your Kokoro instance.
