AI that sounds like you, not a robot
Most AI copy reads like a marketing department wrote it. Quill, AuthorSend's built-in assistant, is tuned around what actually works for author newsletters — it drafts subject lines and body copy in your voice, rates the variants for engagement, and lets you rewrite until it sounds like a letter to your readers.

Teach it your voice once, hear it everywhere
Build a brand voice profile from tone descriptors, vocabulary preferences, phrases to avoid, and example snippets of your real writing. Every generation — subject lines, body drafts, rewrites — is filtered through that profile, so the output reads like you on a good writing day.
- Tone descriptors and vocabulary preferences shape every draft
- Banned phrases stay banned — “limited time” never sneaks in
- Example snippets from your own emails anchor the style
Describe an audience, get the segment
Type “engaged readers who clicked my last launch but haven't bought yet” and the assistant builds the nested segment rules for you — ready to review, tweak, and target. No boolean puzzles, no guessing which fields to combine.
- Plain-English descriptions become editable segment rules
- Generated segments use the same builder you already know
- Review and adjust every rule before you send a thing
One assistant, every step from blank page to send
Quill shows up wherever the work happens — emails, signup forms, social posts, your website — and it's included on every plan.
Rated subject lines
Generate multiple subject line variants, each with a low, medium, or high engagement rating from the assistant — a second opinion before you pick.
Body drafts in your voice
Full body copy generation that pulls from your brand voice profile — a starting draft, not a soulless template.
Rewrite & tone control
Highlight what you have and refine it — warmer, tighter, more excited — without losing what makes it yours.
Optimal send-time prediction
AuthorSend looks at when your readers have opened before and suggests the hour to send, so your email lands at the right moment.
Segments from plain English
Describe who should get the email and the AI assembles the targeting rules for you to review.
On every plan
A generous monthly quota of AI generations is included on every plan — it resets each month, no add-on required.
The assistant is included on every plan. The allowance is metering, not a paywall.
Every tier gets the same features — brand voice, subject lines, drafts — with a monthly generation allowance that resets on the 1st. Higher tiers buy a bigger allowance, never access.
