Comparison
Junco Reader vs Kokoro Web
Both are free, ad-free, browser-based readers built on the same open-source Kokoro-82M voice model. The difference is mostly in how you get text in, and how fast you hear anything at all.

Where Kokoro Web is ahead
It runs in more languages beyond English on its site, and its blog covers the technical side of browser TTS in more depth. If you just want to paste a short passage and are happy to wait out the model download once, it's a clean, focused tool.
Where Junco Reader is ahead
You can drop in a PDF or Markdown file, not just paste text -- and if you don't want to wait on the model download, Junco Reader's Instant tier plays your browser's built-in voice with zero download, no gate to clear first. Junco Reader is also installable as an app, and it's built by the team behind Junco, an iPhone app that reads your email newsletters aloud every morning with the same voice family.
Try it yourself -- drop in a PDF or paste an article, and switch to the Instant tier if you don't want to wait on a download.
