Built-in AI: The next frontier for web experiences
summary
Miravia moves review summarization from servers to Chrome’s built-in summarizer API, running client-side on product pages to avoid constant server calls and cut costs. Implementation uses summarizer.availability to detect device support, creates a summarizer configured as TLDDR short, feeds client-side JSON reviews into summarize(), and swaps from cloud fallback to on-device model with a staged download. AB tests show a 12.4% product-page conversion lift and 3.3% site-wide increase, then roll out to English pages.
