Built For Ghost Publishers

Ghost Chatbot Trained On Your Posts And Pages

Most readers ask the same handful of things — what's in the membership, how to find a specific post, whether you offer a free tier. FastBots reads your Ghost site once and answers those questions in the corner of every page. It can also act as an AI agent when you turn on live internet search or push captured leads into a workflow.

Quick Answers

Really Common Questions About Ghost

What is a Ghost chatbot?

A Ghost chatbot is an AI chat widget you add to a site built on Ghost. FastBots trains on your posts, pages and tag archives, then answers reader questions from that content — things like what's in the membership, where to find a specific essay or how to manage a subscription.

How does FastBots install on Ghost?

You paste a single script into Ghost Admin → Settings → Code Injection → Site Header, then save. The widget appears across every post and page. No theme editing, no Handlebars work and nothing to maintain after install.

Can the chatbot recommend posts from my archive?

Yes. Once the crawl has indexed your posts and tag pages, the bot can point readers to relevant essays based on what they ask. If you publish weekly, turn on auto-retrain so new posts are picked up without you doing anything.

Does it work with Ghost memberships?

The chatbot can answer questions about your tiers, pricing and what's included, and it can link people to your Portal signup. It doesn't manage subscriptions, process payments or read member-only content unless that content is publicly crawlable.

Why FastBots

Why Use FastBots with Ghost

Trained On Your Posts And Pages

Point it at your Ghost domain and it reads your essays, pages and tag archives. Readers get answers grounded in what you've actually published.

Helps Readers Find The Right Essay

Instead of digging through your archive, readers can ask 'do you have anything on tariffs?' and the bot surfaces the relevant posts.

Captures Subscriber Enquiries

When someone asks about the paid tier or wants a reply from you, the lead form collects their email and routes it to your inbox.

Answers Membership Questions 24/7

Pricing, what's included, cancellations, how to log in — answered the moment a curious reader looks at your sidebar, not three days later.

Auto-Retrain As You Publish

On Business plan and above, FastBots can re-crawl your site daily or weekly so the bot always knows about your newest posts.

Speaks Around 95 Languages

Readers can ask in their own language and get a reply in the same language — useful if your newsletter has an international audience.

Acts As An AI Agent Via Workflows

Push captured emails to Mailchimp, ConvertKit or a Google Sheet through Zapier or Make once the chat ends. Pair with live internet search for current-events questions.

Styled To Match Your Theme

Set the widget colour, avatar and welcome message to match Casper, Edition or your custom theme. Remove the FastBots badge on Premium and above.

Real Scenarios

Where It Earns Its Keep

Membership Pricing Questions

Answers what each tier costs, what's included and what the difference is between free and paid — without making the reader hunt for it.

Archive Search By Topic

Readers ask about a topic and the bot recommends the two or three best essays you've written on it, with links.

New-Subscriber Welcome Help

Handles 'where do I log in?', 'how do I update my email?' and 'why didn't I get the newsletter?' so you don't have to.

Press And Sponsorship Enquiries

Captures the name, outlet and what they're after, then emails you the details so you can reply when you're ready.

Podcast And Episode Lookups

If you publish a podcast through Ghost, train the bot on your show notes so listeners can ask 'which episode covered X?'

Book Or Course Questions

Answers questions about a book you've published, a paid course or any landing page on your Ghost site that explains an offer.

Reader Q&A Capture

When someone wants to ask the author directly, the bot collects the question and emails it to you — ready for the next subscriber Q&A.

Refund And Cancellation Triage

Explains your cancellation process and points the reader at the Portal page, while logging the conversation so you can follow up if needed.

Point It At Your Ghost Site

House voice

Sound like the author — thoughtful, calm, no marketing voice. If a reader asks something you don't know from the published posts, say so and offer to pass the question to the author.

Set The Tone And Guardrails

Tell the bot how to sound, what topics to stick to and what to do when it doesn't know. Add a custom fallback for 'email the author' moments.

Paste One Line Into Code Injection

Copy your widget script, open Ghost Admin → Settings → Code Injection, paste it into Site Header and save. The bot appears across every page.

Honest Comparison

Most Ghost publishers pick between a contact form, a third-party search widget, or doing nothing and answering everything by email. Here's how a trained chatbot compares.

Got Questions?

Frequently Asked Questions

The ones we hear most before teams sign up. If yours isn’t here, our support team replies within hours during business days.

Will the chatbot work on the free Ghost plan?

Yes. Ghost's Starter plan supports Code Injection, which is all you need to paste the FastBots script. The widget runs from FastBots' side, so it doesn't add load to your Ghost instance.

Can it read my member-only posts?

Only if those posts are publicly accessible to the crawler. Member-gated content sits behind login, so the bot can't see it. Most publishers train the bot on public posts, the about page and the membership page — that's usually enough to handle reader questions.

Does it work with Casper or my custom theme?

Yes. The widget is installed through Code Injection, so it sits on top of whichever theme you use — Casper, Edition, Source or a custom build. You set the colour and avatar in FastBots to match.

Can it manage subscriptions or process payments?

No. The chatbot can answer questions about your tiers and link readers to your Portal signup, but it doesn't manage subscriptions, take payments or change someone's membership. Those still go through Ghost's Portal and your payment provider.

How does it stay up to date when I publish a new post?

On Business plan and above, you can schedule auto-retrain daily, weekly or monthly so new posts get picked up without you doing anything. On lower plans you can re-crawl manually whenever you've published something you want the bot to know about.

What happens when someone asks something it doesn't know?

You write the fallback message. Most publishers set it to something like 'I'm not sure — want me to pass this to the author?', which triggers the lead form. The question and the reader's email then arrive in your inbox.

Can I send captured emails to my newsletter tool?

Yes, through Zapier or Make. When a lead is captured, the workflow can push the email into Mailchimp, ConvertKit, Beehiiv or a Google Sheet. These are workflow connections, not native integrations — you build them once in Zapier or Make.

Is there a human handover option?

Yes, on Business plan ($89/month) and above. You set availability hours; outside those hours the bot handles everything on its own and captures leads. During your hours, the bot can hand the conversation over to you to reply in real time.

Will it slow my Ghost site down?

The widget loads asynchronously, so it shouldn't affect your Core Web Vitals in any meaningful way. If you're cautious about performance, you can also delay the widget load or scope it to specific pages.

How much does it cost to start?

The free plan gives you one chatbot and 50 messages a month with no credit card required — enough to train it on your posts and try it out. Paid plans start at $39/month for higher message limits and integrations, with Live Chat included from $89/month.
