What it does
Newsletter & Substack Writer is a free Grok bot template. Free Grok Bot for newsletter writers: finds ideas, drafts issues in your voice and preps them for Substack or beehiiv. Publishes only when you approve.
Once you add it to Grok Bot, it runs as your own AI agent: it asks a few setup questions, connects the services it needs, and then works through its routines on a schedule, logging every action in an activity tracker so you can always see what it did and what is waiting on you.
Who it's for
Substack, beehiiv, Kit, Ghost and Mailchimp writers, creators, local newsletter operators, coaches and small businesses that send a regular email newsletter.
No coding is required. If you can chat with Grok, you can run this bot: describe your goals in plain English, review what it drafts, and adjust the instructions any time.

- Give me ideas for Thursday's issue".
- You get: 6 ideas with angles and sources, e.g. 'Why three local diners added Sunday suppers' (2 news links + county restaurant license data) and 'The $14 burger math' (USDA beef price data).

- Ask: "Can you post it for me?".
- You get: I can put it in your Substack editor as a draft while you're signed in, with formatting, buttons and preview text filled in.
- You give it a final read and press schedule or publish.
- I never send to your list myself.

- Ask: "How did last week's issue do?".

FAQ
Can it post my newsletter for me?
Only with your approval. It can fill in a draft in your platform's editor while you're signed in, or schedule an issue you've approved, but it never sends to your list or publishes on its own. Substack doesn't offer an official posting API, so on Substack you get paste-ready text or a draft you review in the editor.
Will it sound like me?
It studies 3-5 of your past issues for structure, sentence length, humor and words you avoid, and marks spots for your own stories with [ADD YOUR STORY] instead of inventing them.
Which platforms does it work with?
Substack, beehiiv, Kit (ConvertKit), Ghost, Mailchimp and most others. It formats the issue for your platform and you sign in to your own account.
Does it make up facts or quotes?
No. Every fact and number gets a source link, quotes are checked, and it never invents testimonials, statistics or personal experiences. Sponsored content is labeled.
Will it act without asking me?
No. It drafts and proposes; nothing is sent, posted, filed, bought, booked, cancelled or deleted until you approve it.
Is my data shared anywhere?
No. Files stay in the bot's own workspace, you sign in to your own accounts, and it never stores passwords.
