The pipeline

Three steps. Researched. Written. Audited.

A pipeline built for scale. Up to 100,000 leads at a time, processed by a research engine that reads the open web and a writer trained to sound like a thoughtful human, not a template.

  1. 01

    AI search across every platform

    Deep research on every name.

    For each contact and the company behind them, we run a live research pass across the open web. News mentions, recent posts, hires, funding rounds, role context, public profiles. The detail a careful human researcher would gather before writing the first word.

    Live research per lead
  2. 02

    Personalized to a recent business event

    An advanced AI handwrites each email.

    Our writer references something specific to that prospect. A recent launch, a hire, a piece they wrote. Every email and subject line is written from scratch for that one person, tied to your offer. No templates. No merge fields.

    Custom subject + body, every time
  3. 03

    Detector aware proprietary engine

    Layered humanizer audit.

    Every draft passes through our humanizer engine. AI tell phrasing stripped, sentence rhythm varied, banned connectives rewritten, subject lines rechecked across multiple passes. The output looks like a person typed it, because by the time you see it, every machine tell has been removed.

    No two emails look alike
Built for scale.
Concurrent research, parallel writing, atomic credit accounting.

Process lists of 100,000 prospects in a single run. Resumable, deduped, and audited at every stage. Push the approved emails straight into Instantly when you're done.

A real first draft

The email you would have written if you had the time.

Every row gets a researched opener, a middle that connects to the opener, and one clear ask. No "I hope this finds you well." No bracketed merge fields visible to a human ever again.

A Tuesday thought on Quill & Loom's pricing page

Hi Avery,

I saw you shipped the new pricing tiers last week. The line about "we charge by the hour, not the seat" is the kind of copy that earns trust before someone has even decided to buy.

We help teams like yours turn a CSV of accounts into 200 first emails in an afternoon, without the AI tells. If a quick walkthrough sounds useful next Tuesday, I'd be glad to send a calendar link.

Either way, the new site is genuinely good.

What customers say
"We replaced three contractors and a Zapier route with one upload box."
Imani O. · VP Marketing, Halftone
"The first email actually sounded like me. The second one sounded like me on a good day."
Soren L. · Founder, Vesper Robotics
"It survived a 47,000 row CSV without flinching. That alone is worth the price."
Priya B. · Head of RevOps, Tideline
