What This Workflow Does

This automation solves the time-consuming process of creating Instagram carousels by connecting AI research tools with design automation and publishing platforms. It eliminates the manual work of compiling research, formatting slides, and scheduling posts—reducing what typically takes 3-5 hours to a fully automated process.

The workflow begins with AI-powered topic research, structures the content into carousel slides, formats the design using Nano Banana Pro, then publishes through Slack integration with Instagram. It ensures brand consistency while adapting content based on performance data and audience engagement patterns.

How It Works

1. AI Research Phase

The workflow starts by analyzing your topic using AI research tools that scan multiple sources. It identifies key points, statistics, and visual concepts that perform well in your niche, structuring this into a content outline automatically.

2. Content Structuring

AI transforms the research into carousel-friendly content chunks, determining optimal slide count and information distribution. It creates natural transitions between slides and formats text for maximum readability on mobile devices.

Pro tip: Configure the AI to analyze your past high-performing carousels and replicate their successful structural patterns.

3. Design Automation

Nano Banana Pro takes the structured content and applies your brand templates automatically. It ensures consistent typography, color schemes, and layout across all slides while optimizing image sizes for Instagram's specifications.

4. Slack Approval & Publishing

The completed carousel gets sent to a designated Slack channel for team review. Once approved (or after a set timeout period), the workflow publishes directly to Instagram with optimized captions and hashtags based on your preset rules.
