Create a specialized GPT for brand-consistent content creation that automatically saves drafts to Notion and notifies your team via Slack when ready for review.

Workflow Steps

1

ChatGPT (Custom GPT)

Build brand voice content assistant

Create a custom GPT trained on your brand guidelines, tone of voice examples, and content templates. Include specific instructions for different content types (blog posts, social media, newsletters) with consistent formatting, calls-to-action, and brand messaging requirements.

2

Zapier

Capture and format GPT output

Set up a Zapier webhook to receive the custom GPT's content output. Configure parsing rules to extract the content type, headline, body text, suggested tags, and publication date. Add a formatter step to ensure consistent structure before sending to Notion.

3

Notion

Create content database entry

Build a Notion database with properties for Content Type, Title, Status (Draft/Review/Approved), Body Content, Tags, Created Date, and Assigned Reviewer. Configure Zapier to create new database entries with the GPT-generated content and set initial status to 'Draft'.

4

Slack

Notify team of new content

Set up Slack integration to automatically post in your content review channel when new drafts are added to Notion. Include the content title, type, and a direct link to the Notion page for easy review access. Tag relevant team members based on content type.
