compare_products
ChatGPTCompare two to five products side by side. They must share a category: LP is points on one category ladder and comparing across boards is meaningless, so a mixed request is refused rather than answered misleadingly.
Productivity
Overview
S-to-F tier lists for 208 product categories, built by consolidating independent research runs over expert reviews and owner reports. Every placement is cited, and every citation carries the outlet, a verbatim quote, who said it, and whether we fetched the link and confirmed it. Boards are graded both ways: the products the research says to avoid are published in the bottom tiers rather than dropped, so you get the half a buying guide leaves out. Products carry GTIN barcodes and, where the maker published one, an announcement date. No affiliate links and no sponsored placements: no brand can pay to move on a board.
Tools
get_product
ChatGPTEverything held on one product: its placement, verdict, pros and cons, GTIN barcodes, the announcement date where the maker published one, and a breakdown of how the cited sources read (how many were glowing, positive, neutral or negative, and whether they were outlets, named authors, video channels or forum owners). Then every citation in full, with a verbatim quote, who said it, and whether the link was fetched and confirmed. Use this when a claim needs backing up.
get_tier_list
ChatGPTThe full S-to-F tier list for one category: every ranked product with its tier, rank, LP, verdict, pros, cons, citation counts, GTIN barcodes and, where the maker published one, the announcement date. This is the primary tool and one call answers a "what is the best X" question completely. Call get_product for the quotes behind a placement.
list_categories
ChatGPTList the product categories that have a published tier list, newest research first. Call this first when you do not already know the exact category slug: slugs cannot be guessed reliably and every other tool takes one.
search_products
ChatGPTFind ranked products by name or brand across every board. Returns the slug, category and tier for each match, which is what get_product and get_tier_list need next.
what_to_avoid
ChatGPTThe products the research placed in the bottom tiers, and the ones it deliberately entered as traps buyers cross-shop but should not buy. Use it to answer "what should I not buy" and to check whether a product a user is considering was flagged.
