Bulk Root Domain Extractor

Paste hundreds of URLs and instantly get back the unique apex domains. Strips www, subdomains, paths and params, then de-duplicates.

Bulk URL Opener

Open dozens of URLs at once in new browser tabs. Configurable delay so popup blockers stay happy.

Cross-multiply two or more keyword lists into every PPC combination (broad, phrase, exact) for Google Ads, Microsoft Ads, and Amazon Ads in one paste.

LLMs.txt Generator

Generate an llms.txt file (the AI-era robots.txt) from a sitemap URL or raw URL list. Gives ChatGPT, Claude, and Perplexity a clean map of your content.

Logo Finder

Find any company’s logo by domain, stock/ETF ticker, or ISIN. Returns the brand’s primary logo via a public CDN.
