The words inside your product are part of the product.
SparkWren reads every button, prompt, form field, error, and empty state — then rewrites the ones that confuse users, and keeps your product's language consistent as it grows. Small words. Clear actions.
Something went wrong.
Your file couldn't be uploaded because it's over 25 MB. Choose a smaller file and try again.
Vague errors hide the cause and the fix. Rewrite names the limit, the failed operation, and the next click.
Click the words. Watch the product change.
Five product states on one operable screen. Turn the Language Dial or switch locale — the copy re-forms in place. No empty scroll theater; every version is here on click.
Everything your product says, in one place
Approved copy, locked terminology, and every missing state — one connected system your whole team writes from.
Not a writing tool — a product-language check
SparkWren is not a general AI writing tool, not a brand-ad generator, and not full product-design software. It's the layer that keeps the words users actually operate correct and consistent.
