Give your AI assistant something only you know about your buyer
Add one verifiable fact and a real customer story, choose a tone, and this writes the prompt to paste into your AI assistant, with your banned words ruled out. Check what comes back before it goes live.
Insight Injector: why what you know about the buyer beats how well you phrase it
A sentence can be well built and still miss, if it only describes the product and never touches what the reader needs from it. Insight Injector takes a fact you hold about the buyer and a real customer story, and writes the prompt that tells an AI assistant to argue from that reality. This guide is for anyone who has the facts about a product but wants the copy itself to argue from the reader's position.
-
Tell it what you know about the buyer
Enter one verifiable fact and a real customer story, and the words you never want used.
-
Take the prompt it writes
Insight Injector assembles those details into a prompt to paste into your AI assistant.
-
Check it before you publish
Read the result against what you actually know about the buyer, and keep only what holds up.
Insight Injector
Fill in your business name, one fact a stranger could check, and one real customer story. Pick a tone and edit the banned word list below. The box at the bottom rebuilds itself into a ready-to-paste instruction block every time you change something, telling an AI assistant to write your site copy without the usual AI padding.
Turn a vague line into one only your product could say
Insight Injector takes a flat sentence and asks what detail is missing: a number, a name, a specific outcome. Add what you know about your buyer, and it rebuilds the line around that. It's built for anyone drafting their own copy who can tell a sentence is dull but can't work out why, and the tool can misjudge the fix, so the final wording stays with you.
