35 Substack notes in one click.

Here's how -> Watch the full demo

Daily substack notes work.

Every piece of data says the same thing: newsletter writers who post Substack notes daily grow faster than those who don’t. The compounding is real. The proof is everywhere.

So why do most of us skip it?

Because scheduling notes manually is friction. Copy the title. Paste the body. Pick the time. Confirm. Repeat 35 times. And it’s not getting easier. Substack is growing. Expectations for consistency are rising. The gap between people who show up daily and people who mean to keeps widening.

The writers winning on Substack right now aren’t doing more. They’ve removed the tasks that were just annoying enough to skip.

Then I connected with Lucija.

Today’s special guest

Lucija Tomcic is non-technical. She works at an AI startup and runs BRISK, a newsletter for people who want to understand AI without becoming a developer.

She had the same problem. 79 notes drafted in Notion. Good ones. She never posted them because scheduling one by one was exactly annoying enough to keep pushing to tomorrow.

So she built the tool that does it for her.

Here’s what she built and what you can take from it.

The “wristband”: scheduling without an API

Substack has no official API for scheduling notes. Lucija worked around it with a session cookie — what she called a “wristband” because it’s what identifies you to the platform. Her tool reads a CSV of notes, authenticates with the cookie, and schedules all 35 in one click.

No developer. No agency. Just Claude Code and the willingness to figure it out.

The 8-agent growth engine

Once scheduling was solved, she built the layer on top. A growth engine to write performing notes.

Five agents running in parallel:

→ One analyzing her latest article for note ideas

→ One tracking when her audience is most active

→ One monitoring what competitors are posting

→ One pulling her best evergreen content

→ One reviewing past note performance

A ‘Synthesizer’ agent takes all of that research and builds a cohesive weekly game plan based on a specific content ratio. He hands it over to the writing agent who drafts the notes for the whole week. Then, the human in the loop, reviewing and editing all notes before scheduling. The retro agent reviews it all.

Not one bloated prompt. Five focused agents running at the same time, three more in a sequence - faster and cheaper than a single long chain.

The retro agent. The part nobody talks about.

Every time Lucija edits a note before publishing, the system logs the change. The retro agent reads those edits. Week after week, the drafts get closer to how she actually writes.

The system gets better the more she uses it. Not because it’s smarter. Because it’s been watching.

The result

She had 10 subscribers when I first connected with her. She’s at 350+ now.

Not from a viral post. Not from a growth hack. From showing up daily because the friction was gone.

Recommend Lucija’s newsletter BRISK to someone.

She’ll add you to the GitHub repo and walk you through the setup herself.

She deserves the subscribers.

Most of us aren’t inconsistent because we’re lazy. We’re inconsistent because the gap between intention and action is just wide enough to fall into.

Close the gap. The habit follows.
