On https://kagi.com/summarizer, and when using the browser extension to summarize a needlessly wordy article or blog post, it would be nice if the summary also included a button to start TTS narration, similar to the implementation on news.kagi.com. 
While the existing implementation on news.kagi.com works fine, I would also prefer it to work like Kindle's "Immersion Reading," where the currently spoken word is highlighted in the article text. This allows for a more focused reading experience.
I use this regularly in the Readwise Reader app:
The Summarizer probably wouldn't need that audio playback UI, because the summaries should already be short enough, but highlighting the currently spoken word (blue in the screenshot) is really helpful for cases where I want to actively consume the content.
