Liso is a text-to-speech tool that converts any highlighted web content into audio you can listen to on demand. Users can select text from articles, newsletters, Substack posts, social media threads, or any webpage, then send it to their Liso library via a Chrome extension or by pasting directly into the app. Liso reads the content back using high-quality AI voices with adjustable playback speed and cross-device resume support. A Pro tier unlocks unlimited listens, premium voices, and offline downloads.
