Build a Newsletter Writer
Build a Custom AI around your past issues, your format, and your ideas board, so you never re-explain your newsletter to an AI.
You'll end up with a Custom AI that already knows your newsletter's audience, format, and voice. Open Custom AI, click +, pick Build a Custom AI, and @ mention your best past issues.
Build it
- 01
Start the builder
Open Custom AI in the sidebar. Click +, then Build a Custom AI.
- 02
Describe your newsletter
Say who it's for, how an issue is structured, and how long it runs. @ mention 5 to 10 of your best issues.
- 03
Save it
Answer its questions, review the card, click Create Custom AI, then Create.
- 04
Add your ideas board
On the Knowledge tab, click Add from workspace and pick the board where you collect ideas. It stays live, so ideas you add later show up too.
- 05
Set your starters
On Configure, add up to 4 Conversation starters.
What to put in
| Part | What to use |
|---|---|
| Instructions | Your format. For example: "Hook, one core idea, one practical step, soft CTA. 800 to 1,200 words. Propose three angles before drafting." |
| Knowledge | Your best past issues, as documents or one board. |
| Sources | Your ideas board. Optional: one or two newsletter writers you admire, via Add a creator. |
| Starters | "Propose three angles from my ideas board." "Draft the next issue." |
Use it
- Angles first: "Propose three angles from my ideas board that I haven't covered lately."
- Draft: pick one and ask for the full issue.
- Edit: push back like you would with an editor. "The hook is weak. Tighten section two."
Every chat with it stays on its Conversations tab, so last month's decisions are easy to find.
