What it is

HeyNews is an AI newsletter writer for Substack writers. It imports your public Substack archive, trains a Voice Profile from the issues you have already published, watches the sources you trust (RSS feeds, sites, X, Reddit, saved articles), and drafts your next issue in your voice for you to review and publish. Plans start at $39/mo with a 14-day free trial.

HeyNews does not replace Substack. Substack stays where your subscribers, payments, comments, and publishing live. HeyNews is the production layer that turns your archive plus your sources into a draft that already sounds like the writer your audience subscribed to.

How HeyNews works with Substack

Paste your Substack URL: No login to Substack, no setup, no browser extension. HeyNews fetches the public issues at your Substack URL and uses them as the starting point for your Voice Profile.
Build your Voice Profile from the archive readers know: HeyNews studies the tone, structure, signature phrases, and the way you handle weekly essays vs link letters vs Q&As. Real published issues beat any prompt-engineered "style guide".
Add the sources behind your next issue: RSS feeds, blogs, X profiles, Reddit threads, and saved articles. HeyNews scans them and surfaces a ranked shortlist of stories that match what your readers already engage with.
Review the draft, then publish from Substack: HeyNews drafts the issue with subject line and preview text options. Edit until it sounds right, copy the finished version into Substack's editor, and publish it yourself.
Run a Substack and a second newsletter side by side: On Pro and Team plans, a Substack and a Kit or beehiiv newsletter can both live in one HeyNews account, each with its own Voice Profile, sources, and draft history.

What to expect today

HeyNews creates the draft. It does not publish to Substack for you. Today you review inside HeyNews, copy the finished version into Substack, and publish it yourself. Voice training works best with public posts; if your archive is mostly behind a paywall, HeyNews will have less to learn from at first. See the FAQ for details.

Why it feels different for Substack operators

Trained on the archive your readers already know: Substack does not give Substack writers a strong AI drafting workflow. HeyNews learns from the public issues you have already published, so the first draft starts in the voice your audience actually subscribed for.
A shortlist of stories before you start writing: Substack is where you write and publish. HeyNews helps before that by scanning your sources overnight and surfacing a ranked shortlist of stories worth your time, so Sunday is not "what should I write about?".
Separate Voice Profiles for separate cadences: Your weekly essay and your monthly link letter read differently. HeyNews keeps separate Voice Profiles, sources, and draft histories for each, so the wrong tone never bleeds into the wrong issue.
Subject lines, preview text, and sharper takes included: Each draft includes subject line and preview text options plus opinionated commentary on the stories, so the issue is closer to ready by the time you open Substack.
No more pasting into ChatGPT every week: You stop copying three best issues into a system prompt every Sunday. HeyNews trains on your full archive once and uses it as voice memory for every future draft.

Pricing

Plan	Plan details	Price
Starter	15 issues / month · 2 Substack publications	$99/mo
Pro	45 issues / month · 4 publications	$299/mo
Team	90 issues / month · 10 publications · 100 AI revisions per draft	$499/mo

Your Substack subscription stays separate (free or paid; HeyNews works with both). HeyNews plans start at $39/mo and include a 14-day or 5-issue free trial, whichever ends first.

Use cases

The Substack writer who got tired of pasting into ChatGPT

ChatGPT did not know your archive. Custom Instructions helped a little. Pasting your three best issues into the system prompt helped more. The drafts still sounded off. HeyNews trains on your full archive automatically and the difference shows up on the first draft.

The 10k-subscriber Substack with a Tuesday essay

You publish every Tuesday. The essay takes a full Monday to write. HeyNews drafts it Sunday night so Monday is a one-hour review instead of a six-hour write, and the essay still sounds like you, not like an AI rewrite of you.

The Substack-to-beehiiv migrator mid-move

You are moving to beehiiv but have not switched yet. HeyNews works with both. Start with your Substack archive today, then layer in your beehiiv history once the migration finishes, without retraining the Voice Profile from scratch.

The Substack writer with a second newsletter elsewhere

You run a Substack and a Kit (or beehiiv) newsletter for a different audience. HeyNews keeps both inside one account with separate voices, sources, and draft histories. Switching between them is one click.

FAQ

Does HeyNews replace Substack?

No. Substack stays where your subscribers, payments, comments, and publishing live. HeyNews is the production layer that drafts each issue from your archive plus your sources, so the page you copy into Substack is already written in your voice.

Why does HeyNews use my public Substack archive?

Substack keeps more of its publishing workflow closed than beehiiv or Kit, so HeyNews works with what is publicly visible. Your published issues are enough to learn your tone, structure, and recurring patterns. No extra setup required.

How does HeyNews import my Substack archive?

Paste your Substack URL into HeyNews. It fetches the public issues you have published and trains a Voice Profile from them. No login to Substack, no setup, no browser extension to install.

Does HeyNews push drafts to Substack?

Not today. Drafts live inside HeyNews until you decide they are ready. When you finalize one, copy it into Substack's editor and publish it yourself. That keeps you in editorial control and means a misclick never publishes to your list.

Can I use HeyNews if my Substack archive is paywalled?

HeyNews trains on what is publicly visible: free posts and the public preview portions of paid posts. If your entire archive sits behind the paywall, HeyNews has less to learn from at first. Start with your free posts and supplement with example issues during onboarding.

Does HeyNews work for new Substack writers without an archive?

HeyNews works best with at least three published issues. With fewer, the first draft leans on the briefs you write during onboarding. Publish two or three issues first, then connect. The Voice Profile sharpens with every issue you add.

Will Substack subscriber and reader data show up in HeyNews?

Not directly today. Substack keeps subscriber-level open and click data inside Substack. HeyNews still learns from your public issues, but it cannot read engagement signals the way it can on beehiiv or Kit.

What is the free trial?

14 days or 5 generated issues, whichever ends first. A payment method is required so accounts cannot be recycled. Cancel any time during the trial and you are not charged.
