What it does

Written by AI from the README

Reads selected PDF text aloud with the Kokoro text-to-speech model running inside Zotero, with a player bar, speed and voice choices. It can keep reading from the selected sentence to the end of the paper.

Lets you listen to papers instead of reading on screen. It skips citations and repairs hyphenated words. The voice model, 163 MB by default, downloads on first use; after that it works offline.

Your rating of Kokoro Reader v0.3.1

Your review is public, under the name you give, and published with the directory's data under CC BY 4.0. Links are removed. We never store your IP address: a scrambled code made from it is kept for 30 days to catch fake reviews. Every review is checked before it's published; how fake ones are spotted isn't published, so it can't be gamed.
