SEO + AI citation, Polish-language tool hub (PL first)
Why + sources
Importer searches 'kalkulator cla z Chin' / 'transport z Chin cena' -> runs the tool on his shipment -> saves the result by e-mail -> asks for quotes; AI answers cite the tool pages.
Certainty: Free tools still win search (Stratabeat: +20.7% vs +11.5% organic growth; Ahrefs: single tools 17.8k-54.7k visits/mo). But the PL results page is crowded: at least 6 free PL calculators (nazysk.pl, kalkulatorrentownosci.pl, shiphub.pl, chinskiraport.pl, kontener.pl, dobrykalkulator.pl) and forwarder blogs (itscargo, spnlogistics, peko, fullbax, kolejchiny, importix) already rank; ShipHub.pl keeps a monthly 'stan na pazdziernik 2026' cost page; Google started building calculators inside AI Overviews on 19 Aug 2026 (English first).
Cash: Estimate: domain + hosting + e-mail service ~$80/mo; native Polish proofreading of 4 tools ~$200; TARIC/VAT data free. AI build cost ~0. To first result = setup + ~4 months running.
Result: Estimate. Keyword volumes for 'import z Chin', 'transport z Chin', 'clo z Chin kalkulator' are NOT published (Senuto/Ahrefs paywalled). Quote requests = visits x ~30% real business shipments x 2-4% form rate -> ~10 (low) to ~70 (high) per month.
