Two products. One table.
Give it the page for each product. It reads both of them in full and returns one table of what is actually different, with the number of the page beside every cell.
One run, nothing edited.
Look at the rows where one page stayed silent. The cell says so, instead of filling itself in from somewhere else.

Command in, answer out.
The lines in the middle are the agent reading. Each one names a page, what it weighed once the markup was gone, and where it came from.

Two or more URLs, one page per product: the product page, the pricing page or the documentation page that says what it does.

One table, a row per feature and a column per product, each cell in the wording the page used with the source number next to it, and every gap marked as not stated instead of guessed.
The same job by hand is two long pages, a scroll for every row, and a table you end up typing twice.
The command that produced all of this.
Paste it as it is and watch it work, then swap in your own pages. With your Lyrenth key set, it prints the finished prompt and its numbered sources, ready for whichever assistant you already use. Point it at an OpenAI-compatible endpoint and it answers on its own, the way the run above did.
