Use Harmony Publishing inside ChatGPT and Claude
The Harmony Publishing Assistant brings our packages, prices and printing calculator into your AI chat. Ask in your own words, compare options, and send us an enquiry when you are ready. It is free, and it works for authors anywhere.
What it does
Show packages and prices
Lists Harmony Publishing's current self-publishing packages, what each includes and its price in $ (USD), from the same catalogue as our packages page.
Recommend a package
Suggests the package that fits your book type, page count, format, manuscript stage, the services you want and your budget, and explains why.
Estimate printing
Gives a printing-only estimate from our calculator for 1 to 1,000 copies by page count, trim size, interior, paper and binding. Larger runs and special specifications get "request a quote".
Send an enquiry, only when you say so
Shows you the details first. Nothing is sent unless you confirm and agree to be contacted; then our team follows up by email.
Printing figures are estimates; our team confirms the final quote. Prices are shown in $ (USD). You can check the same figures yourself on our packages page and the book printing cost calculator.
Try these prompts
- “Show me your self-publishing packages”
- “Estimate printing 100 copies of a 200-page 6x9 paperback”
- “Recommend a package for my first novel on a $1,000 budget”
Use it in ChatGPT
Open the Harmony Publishing Assistant in ChatGPT, add it, then ask one of the prompts above.
Use it in Claude
Our Claude directory listing is on its way. Until then, add the assistant to Claude as a custom connector:
- In Claude, open Settings → Connectors.
- Choose Add custom connector.
- Name it “Harmony Publishing Assistant” and paste this address:
https://assistant-api.harmonypublishing.net/mcp
No sign-in is needed. Then start a new chat and ask one of the prompts above.
Your details stay with you until you confirm
Browsing packages, recommendations and printing estimates sends nothing to us. The assistant only sends an enquiry when you have reviewed your details and agreed to be contacted. Read our privacy policy for how we handle an enquiry and how to ask us to delete it.
