Listen
Listen reads text aloud with your browser's voice or the Rivul voice. Neither needs an API key.

Listen to a paper, a draft, or text
- Step 1: Open Listen in the sidebar, under Convert (rivul.ai/app/listen).
- Step 2: Paste text, or use Choose a paper or draft to pick a library paper (its extracted text) or one of your drafts (the manuscript without its reference list).
- Step 3: The sentence being read is highlighted. Click any sentence to start there, and change the speed while you listen. Citation markers such as [3] are shown but not read.
Voices and limits
The browser voice is the default. It uses a voice installed on your device, starts instantly, sends nothing anywhere, and has no limit.
On an iPhone or iPad, Safari may pause the browser voice when the screen locks or you switch apps. Listen resumes it, or reads the current sentence again, when you come back to the page.
The Rivul voice is a natural-sounding voice that runs on Rivul AI's own server in Germany: the text is turned into speech there, is not stored or logged, and is never sent to an AI company. It can read 300,000 characters per account a day. Your browser keeps that audio so the same text is not sent twice.
Recording in Transcribe stops Listen, and Listen stops a recording, so the microphone never picks up the voice.
