Powerful Plugins

Audience Builder

The newsletter swap manager for authors. It finds the swaps, scores them for your list, signs you up with your approval, writes the emails in your voice, and remembers who actually reciprocated.

Newsletter swaps grow your list. Managing them eats your week.

Audience Builder is a Claude Cowork plugin that runs the whole swap lifecycle across BookFunnel, StoryOrigin, and BookClicker: finding the swaps and group promos that fit your list, ranking them with reasons, signing you up with your approval on every submission, writing the swap emails in your voice with the partner's cover already in place, and tracking who held up their end.

It works on your own logged-in accounts through the free Claude in Chrome extension, shows you everything before it goes, and never sends an email for you.

Sound familiar?

Your swap spreadsheet fell behind in March and never caught up.
It's 11pm the night before a share date and you're hunting for the partner's cover image.
You just swapped with the same author who ghosted you last quarter, because who can remember?
A promo banned AI-assisted books in paragraph four and you didn't see it until after you joined.

How Audience Builder works

Set up once

Each pen name's genres, list size, platforms, and weekly send budget. Sixty seconds per pen name.

Find and rank

It scans the live listings on all three platforms, filters out anything that bans AI-assisted books, and ranks what's left by genre fit, list parity, partner reliability, and expected subscribers, with the reason on every row.

It fills each sign-up and waits for your approval before anything is submitted. Partner covers get captured at sign-up, so they're never missing later.

Fulfill and learn

Swap emails written in your voice with tracking links wired, deadlines on one calendar, results logged, and partners remembered. After a few swaps it runs on your real numbers, not guesses.

What's in the system

Three platforms, one system
BookFunnel, StoryOrigin, and BookClicker, worked from one hit-list instead of three open tabs.
The AI-restriction filter, always on
Listings that prohibit AI-assisted books are excluded automatically and shown with their exact wording, so you never accidentally break a promo's rules.
Swap emails in your voice
The partner's book pitched on its real hooks, your pen name's voice, the cover embedded, the tracking link wired. Paste-ready, or drafted right in your email platform.
A partner memory
Who reciprocated, who confirmed their shares, who ghosted twice. Plain facts, remembered forever, factored into every future ranking.
The confirmation loop, closed
BookClicker requires confirming your share after the email goes out. Audience Builder tracks every confirmation until it's done, protecting your reliability score.
Multiple pen names
Separate profiles, partners, calendars, and voices, all on one system.

Questions, answered

Does it send things without me?

Never. Every platform submission is shown to you and waits for your yes, one at a time. And it never sends an email; it drafts, you send from your own platform.

Which platforms does it work with?

BookFunnel, StoryOrigin, and BookClicker, on your own logged-in accounts through the free Claude in Chrome extension. Use one, two, or all three.

For email, it drafts paste-ready copy for any platform, and can draft directly inside MailerLite, Kit, Mailchimp, ActiveCampaign, or Flodesk.

How does it know which swaps are worth it?

Genre fit, list-size parity, partner reliability, and timing, scored with the reason shown on every row. Subscriber estimates start as clearly labeled ballparks and switch to your own tracked results after a few swaps.

Do I need anything special to run it?

Claude Cowork on a Claude Pro or higher plan, plus the free Claude in Chrome extension signed in to your promo platforms.
