Why Chatref
A better prompt is just the start – why not let AI answer for you?
This tool sharpens one prompt at a time. Chatref takes the next step: it reads your whole site and help docs, then answers every visitor with grounded, cited replies – no prompt engineering needed. It says "I don't know" instead of guessing and hands off to a human when a conversation needs one. Live in about a minute.

Is the AI Prompt Optimizer free?
Yes. It's completely free and needs no sign up or credit card. Paste a prompt, add an optional goal, and get a tighter version back with a list of the changes.
What does it actually change?
It removes vague wording, adds the missing context and constraints, and structures the request so a model knows exactly what to return. Every change is listed so you can see the reasoning, not just the result.
Why does prompt quality matter for a support chatbot?
A clear prompt is the difference between a guessy answer and a grounded one. Chatref applies that same discipline on your site – it answers only from your content, cites the source, and says "I don't know" instead of inventing facts.
Can Chatref answer my customers automatically?
Yes – that's what Chatref is. Point it at your site and docs once, and it answers every visitor 24/7 with cited responses and human handoff, pay-as-you-go with $50 in free credit.
