Three steps
Upload your catalog
CSV with SKU, brand, features, and target keywords. Use our template — same columns as your export.
Review the flags
Every violation is marked with the exact rule and a suggested fix. Nothing is rewritten silently.
Review and export
Same column structure you imported, plus the cleaned title, a per-SKU score, and every flag. Nothing is uploaded for you.

Before / after
Before
12PCS Silicone Kitchen Utensils Set Best Quality 100% Food Grade Heat Resistant Non-stick Spatula Spoon Whisk Free Shipping
After
12-Piece Silicone Kitchen Utensil Set, Heat-Resistant to 446°F, Non-Stick Spatula & Spoon Set with Wooden Handles, Grey
Three problems, one rewrite: Best and 100% are absolute claims, Free Shipping is a promo term, and the title is over 200 characters. The rewrite keeps the selling points and drops the risk.
Why not just use ChatGPT?
You can — for ten listings. It writes better prose than we do. But a chat window doesn't know your category's character limit, can't process 500 rows, and won't tell you which word got your listing suppressed.

FAQ
Which marketplaces are supported?
Amazon US, UK, and DE at launch. TikTok Shop is in beta.
Do you store my files?
No. Files are processed in memory and deleted within one hour.
What if my category has a shorter title limit?
Pick the category in step 2 — we apply the stricter limit and tell you why.
Can I edit the output?
Yes. The export is a plain CSV; every field is editable.
Is this a replacement for a copywriter?
No. It is a first pass and a rule check. Most sellers still edit 10–20% of lines.
