AdCreator AI

When the November 10 China tariff cliff hits, every e-commerce seller importing through Vietnam/Mexico is going to see their margins evaporate. We shipped a free HTS-code-stacking calculator inside AdCreator this week — paste any HTS code + origin country, get the real US duty rate stacked (base + Section 301 + IEEPA fentanyl + reciprocal) with the projected post-cliff rate. The technical bit: we pulled all 19,856 HTS codes from the USITC API (`?from=0&to=99&format=JSON&styles=true` — the `styles=true` part is required, took an hour to figure out from their docs) into Postgres. Frontend uses pg_trgm for autocomplete on the chapter labels. AI explanations for what each stacked rate means come from our existing 11-provider LLM fallback chain (Claude → GPT → DeepSeek → Llama → ...). It's live at adcreator-ai.com/tariffs/calculator. Free with every tier. We're the only AI ad platform that has this — every other tool does ads OR SEO; we do both PLUS the tariff exposure layer no one else builds. Trade-off we made: the calculator math is current rates only; the Nov 10 projected stack is a fixed lookup, not a daily Federal Register parse (that's Phase 2, deferred until we see waitlist intent). Phase-by-phase is the only way a solo dev ships this kind of compliance tool without writing legal-grade code on day one. Builder Q: anyone else here doing dual-purpose tools where the second feature is the moat? I'm curious what categories you'd add this kind of layer to. 🔗 adcreator-ai.com · /tariffs/calculator *Why this works: real technical detail + a number (19,856) + an honest trade-off + audience-fit question. The "we found `styles=true` in the docs" is the kind of war-story builders engage with.*
