# Should I Use it > Public crawl-based fit checks at https://shouldiuse.io Should I Use it reviews a product from a public URL. The output is a buy or don't-buy fit check from a product advisor. The advisor names what the product is, who it is for, who it is not for, its purpose, when it is overkill, and what to use instead. Crawlers, bots, and LLMs may fetch every public page. robots.txt allows all user-agents. ## Crawl - [Home](https://shouldiuse.io/): paste a product URL to start a Check - [Robots](https://shouldiuse.io/robots.txt): User-agent * / Allow / - [Sitemap](https://shouldiuse.io/sitemap.xml): public pages, reports, and vs. pages - [About](https://shouldiuse.io/about): what the site does ## Reports Public reports live at `/r/:slug`. Example: https://shouldiuse.io/r/notion Use the sitemap to list report URLs. Old paths such as `/:slug` redirect to `/r/:slug`. ## Comparisons Vs. pages live at `/vs/:product/:alternative`. Example: https://shouldiuse.io/vs/notion/obsidian ## Optional `/admin` is a password dashboard. It is not in the public catalog. GET on public pages does not challenge bots. Do not POST `/api/analyze` unless a human asked for a Check.
