## Details

A local keyword research tool built on DataForSEO's API. Fetches keywords by category code across 3,182 categories (classified as digital/physical/both), applies server-side filters to minimize API cost, and surfaces results sorted by estimated cost per conversion (CPC ÷ CVR).

Features a visual drag-and-drop pipeline where filters above the Run bar are sent server-side (cheaper) and filters below run locally in the browser (free). Includes a full category browser, negative keyword management with phrase/word matching, saved searches, monitor list, export CSV, and a landing screen to restore previous sessions.

Built in a single index.html + server.js — no framework, no build step. Ran 368 categories in one session for $8.05 and surfaced 43,000+ qualifying keywords.
