StackContacts Press for Substack writers who want Claude to schedule Notes and posts
If your Substack habit is already starting in Claude—brainstorming a Note, tightening a newsletter paragraph, asking for a better hook—the annoying part is the handoff. You finish the writing in chat, then open Substack, paste it, schedule it, maybe add an image, and repeat for every post. StackContacts Press tries to remove that handoff by giving Claude Desktop a publishing toolkit for Substack Notes, article posts, and DMs. At $49 as a one-time purchase, it is priced like a serious utility rather than a subscription add-on. If you want your Claude chat to be the place where the post actually gets scheduled, it is worth a close look.

What you’re actually buying
At $49, StackContacts Press is not a content calendar or a prompt library. It is a publishing bridge: a native Model Context Protocol extension for Claude Desktop plus a local helper app that keeps your Substack session on your machine. Once installed, Claude can stop being a drafting buddy and become the hand that files the work: drafting Substack Notes, scheduling them for specific times, attaching images and link previews, and @mentioning the right profiles. That is the first reason it is interesting—Notes are where a lot of Substack momentum happens, and doing that from chat removes the copy-paste tax.
The second reason is scope. You can create and edit article drafts, schedule posts with a publish time, control whether Substack sends the email, upload images, and list drafts or scheduled posts. For a writer running a weekly newsletter plus daily Notes, that is a meaningful stack: one chat can hold the idea, the edit, the image, and the publish decision. The DM layer adds a relationship-management angle—list threads, read conversations, compose messages, and mark threads read—useful for thanking subscribers, onboarding new readers, or coordinating with a small team.
The final piece is account handling. Up to five Substack logins on one Mac or PC means a personal publication, a client account, and a brand newsletter can live in the same local setup, with Claude asked to use a specific actorHandle. The local-first setup is also part of the pitch: the session stays on your computer, encrypted with an auto-generated key, and the purchase is a download rather than a hosted account. If your bottleneck is moving finished writing into Substack, this is a compact, one-time-price way to close that loop.
Why it’s on our radar
There are 5 ratings at 5.0 and about 14 sales. That is a small sample, but it is enough to show StackContacts Press Gumroad ratings are not empty. A clean early record like that is a reasonable reason to inspect the workflow before deciding.
What actually matters
- Your Claude habit has to be real. If most of your writing starts elsewhere, the value of a Claude Desktop workflow drops quickly. This tool is strongest when the idea, edit, and publish step all happen in the same chat.
- Check the local setup. It runs on Mac or PC and uses a local helper app; DMs need the helper app open while sending. If your machine setup is unusual, confirm the current install requirements first.
- Account count matters. It supports up to five Substack logins on one machine, which is useful for personal, client, and brand accounts. If you need more than that, this is not the right fit.
- Make sure the output fits your cadence. If you need a hosted scheduler, a team dashboard, or a multi-seat workflow beyond the local account model, look at alternatives before paying.

FAQ
What does StackContacts Press do? It gives Claude Desktop a Substack publishing toolkit for Notes, article posts, and DMs, with local account handling.

Is there a subscription? It is a one-time purchase with no subscription fees.
Bottom line
If your main friction is the gap between a good Claude draft and a scheduled Substack post, StackContacts Press is a sharp fit. It is not a substitute for editorial judgment, but it can make the mechanical part—Notes, article drafts, scheduling, and DMs—feel like one conversational step. For a $49 one-time tool that stays local and supports multiple Substack accounts, it is a reasonable upgrade for Claude-native writers. View on Gumroad
