Who we are, what we build, and why it is free.
Clever Marketing Tools is a collection of free, single-purpose marketing utilities — UTM builders, ad-spend calculators, SEO checkers, content helpers. Each tool does one job, does it well, and runs entirely in your browser. No accounts, no data collection, no usage limits.
Most marketing work is a series of small, repetitive tasks: tag a URL, check a ROAS number, trim a title to fit the SERP. Opening a full-scale platform for a thirty-second job is friction you pay dozens of times a week. We build the tools that remove that friction — one focused page per task, instant results, nothing to install.
Every tool runs client-side. Your data never leaves your browser — there is nothing for us to store, sell, or leak. The site is static HTML served from Cloudflare's edge network, which is also why pages load instantly.
clemartools is funded by clearly marked affiliate recommendations for marketing software and SaaS products. Affiliate links never change which tools we recommend or how our utilities work. If a tool saves you time, that is the whole transaction.
clemartools is built and maintained by Wojciech Urban Legend SEO, based in Kraków, Poland. Questions, ideas, partnership inquiries — reach out at [email protected] or visit the contact page.
