We do have that in Exa search:

* Extraction of main content from HTMLs, the index stores markdown representations (free of headers/footers/sidebars/menus etc)

* Serving highlights picking the most relevant part for each result to reduce token usage downstream

* Also serving dynamic highlights where we summarize all the sources at once reducing the token counts even further

see here: https://exa.ai/docs/search/highlights and https://exa.ai/docs/contents/quickstart
