Practical, zero-cost browser utilities built by ecommerce operators and used daily by our own catalog and SEO teams. No account. No data collection. Always free.
Live word count, character count (with/without spaces), sentence & line counter, keyword density table, reading time & lexical density. Perfect for Amazon title length checks, meta description optimisation, and SEO content audits.
Strip repeated words from Amazon product titles, backend keyword fields, Flipkart descriptions, meta tags, and ad copy with one click. Case-insensitive, per-line or whole-text scope, copy & download.
Score your Amazon product title against A9 algorithm best practices — character limit compliance, focus keyword placement, readability index, and stop-word ratio analysis.
Calculate CGST + SGST / IGST for any product category. Supports all GST slabs. Useful for Meesho, Flipkart, and Amazon India sellers pricing new SKUs and calculating landed cost.
We built these tools because we use them internally — every day. Ecommerce sellers shouldn't need a paid subscription to access the basic utilities that make listings better and content sharper.
Every tool in this hub reflects a real workflow used by X4Cart's catalog operations and SEO content teams — not hypothetical tools designed by engineers who've never listed a product.
All tools run entirely in your browser. Your product catalog data, keyword research, and ad copy never touch our servers. Use them safely with your most sensitive business content.
Unlike generic tools, our utilities are built with Amazon, Flipkart, Meesho, and quick commerce constraints in mind — character limits, indexing rules, and algorithm nuances built right in.
New tools ship regularly — Amazon Title Scorer, GST Calculator, Margin Analyser, and more. Bookmark this page and check back, or follow us for updates.
These utilities give you the data. X4Cart gives you the execution — listing optimisation, PPC architecture, sourcing, and full-stack marketplace operations advisory.
