Write product copy from your real specs
List the product's real facts — materials, sizes, what it does. The AI writes copy from those facts only; a missing spec is left out, not made up.
How to use it
- Sign in, then enter the product's real specifications and optional audience.
- Run the task (1 trial).
- Review every claim against your spec sheet, edit inline, then copy.
Limits & formats
Facts up to 4,000 characters. The AI may not invent certifications, awards, measurements or performance numbers — anything absent from your input stays absent. You are responsible for compliance of the final listing text. Output capped at 2,048 tokens.
Privacy
Your specs are sent through YYSI's server to our AI provider (DeepSeek). YYSI stores character counts, token usage and the copy. Results are kept for 24 hours, then become unavailable.
