Why ChatGPT drafts still sound like AI (and what to use instead)

ChatGPT is a blank canvas. HeyNews is connected to your newsletter, your sources, and your past issues, so the draft sounds like you the moment it appears.

What it is

HeyNews is a purpose-built AI newsletter writer. It plugs into beehiiv, Kit, Substack, Ghost, Mailchimp, or any newsletter with a public archive, learns your voice from past issues, pulls fresh stories from your sources, scores them against your audience, and drafts your next issue. You review, edit subject line and preview text, and send from your platform. Every step is built around the newsletter loop.

ChatGPT is OpenAI's general-purpose AI assistant. It can write a newsletter draft if you prompt it well, and the rest of the loop is yours to set up. Projects keep shared files and instructions for a body of work, according to OpenAI's Projects help article (checked October 11, 2026), so you build and maintain the voice, sources, and structure for each newsletter yourself.

What ChatGPT actually does for newsletter writers

ChatGPT is good at

Rewording a paragraph you wrote in a tone you describe.
Brainstorming subject lines and hooks.
Drafting a generic version of a story when you paste in source text.
Fixing grammar and pacing on a draft you already have.

ChatGPT is bad at

Sounding like you. Custom instructions and project files help, but drafts still drift toward a generic AI tone unless you keep correcting them.
Picking what to write about. ChatGPT can search the web when you ask, according to ChatGPT's web search docs (checked October 11, 2026). You still tell it which sources matter and what your audience cares about.
Connecting to your newsletter platform. beehiiv offers its own ChatGPT plugin that can save drafts in beehiiv, according to beehiiv's plugin page in ChatGPT (checked October 11, 2026). HeyNews connects to beehiiv and Kit directly and imports public archives from Substack, Ghost, Mailchimp, and Medium.
Learning from performance. HeyNews uses beehiiv and Kit opens and clicks to rank stories and suggest subject lines. ChatGPT only sees the performance data you paste or connect yourself.

When to choose ChatGPT over HeyNews

You write one newsletter every few months and a $39/mo dedicated tool isn't justified.
Your newsletter is brand new and you don't have past issues for HeyNews to train on (and you're not on a platform with archive import).
You enjoy the prompt-engineering process and want full manual control of every step.
You use ChatGPT for many things beyond newsletters and don't want a single-purpose tool.

When to choose HeyNews over ChatGPT

Writing your newsletter eats 6 to 10 hours a week and you want most of that back.
You are tired of the result sounding like AI no matter how carefully you prompt.
You want the tool to find the stories, not just polish the ones you already pasted in.
You want the next draft to be informed by what worked in the last issue.
You are on beehiiv, Kit, Substack, Ghost, Mailchimp, or Medium and want a tool that connects directly to beehiiv and Kit and imports public archives.

Use cases

The "ChatGPT drafts still sound like AI" operator

You have tried custom instructions, you have uploaded a style guide, you have pasted three of your best issues into a project. The drafts are better than the default but still off. HeyNews learns from your most recent public issues automatically, and the Voice Profile keeps adjusting as your style evolves.

The "spending Sunday afternoon picking stories" operator

You scan 30 RSS feeds, your saved articles, three subreddits, and four X accounts. ChatGPT can summarize stories you paste in or search for, and a scheduled task can repeat that search. HeyNews checks all of your sources automatically and ranks the stories for your audience.

The multi-edition operator

You write a Monday deep dive and a Friday link letter. They have completely different voices. With ChatGPT, you keep a separate project with its own instructions for each edition. With HeyNews, you have two writers and switch by clicking once.

The data-driven operator

You want to know which stories drive opens. ChatGPT only sees the numbers you paste or connect yourself. HeyNews reads beehiiv or Kit opens and clicks and uses them to rank stories in the next draft.

FAQ

Why is ChatGPT not enough?

ChatGPT is a powerful general tool. The newsletter workflow is sourcing, voice, drafting, scheduling, and performance learning, looped weekly. ChatGPT does the drafting step well if you prompt it well, and scheduled tasks can rerun a prompt. Sourcing, voice, and performance learning are still yours to set up and check every issue.

Can I just use ChatGPT with a custom GPT trained on my issues?

OpenAI is moving away from custom GPTs. New GPT creation is not available on personal ChatGPT plans, and OpenAI plans to retire custom GPTs, according to OpenAI's GPTs help article (checked October 11, 2026). A project with your past issues as files is the closest option, but it still leaves sourcing, story scoring, and performance feedback to you.

Does HeyNews use GPT under the hood?

HeyNews uses multiple language models for different tasks. The model layer is abstracted; the value is in the workflow built around it (voice training on your archive, source ingestion, relevance scoring, performance feedback).

How long does voice training take?

A few minutes after your platform is connected. The Voice Profile is ready before your first draft.

Will HeyNews work if I am just starting and have no archive?

Voice training needs at least a few past issues to be useful. If you are brand new, you can either start with ChatGPT for the first few issues to build an archive, then switch, or you can connect a public-archive newsletter you have written elsewhere (a personal Substack, for example).

Is HeyNews worth $39/mo if I am already paying $20 for ChatGPT?

Depends on how much time the newsletter takes you. If the newsletter is 1 hour a week, no. If it is 6 to 10 hours a week, the math works out fast. Try the 14-day trial and see how much time the first three issues actually take.
