Instagram Posting

Post product photos, carousels, and custom photos directly to your Instagram Business account — with AI-powered captions.

On the web: Instagram On the app: Profile tab → Instagram

Getting Started

Connect Your Account

  1. Go to Instagram
  2. Click Connect Instagram
  3. Authorise FLUF in the Instagram login screen
  4. You'll be redirected back with a green Connected badge showing your Instagram username

Requirements: You need an Instagram Business or Creator account. Personal accounts are not supported by Instagram's API.


You can add images from two sources:

From Your Listings

  1. Search for products using the search bar on the left — results appear as you type
  2. Each result shows the product title and all its images
  3. Click any image to add it to your post (1 to 10 images per post)

From Your Device

  • On the web: Drag and drop images onto the carousel area, or click the upload icon to browse files
  • On the app: Tap Upload from Device to pick images from your camera roll (you can select multiple at once)
  • Supported formats: JPEG, PNG, WebP (max 8MB per image)

You can mix both — add product photos and your own custom images in the same carousel.


On the web:

  • Preview — Click any thumbnail to preview it full-size
  • Navigate — Use the left/right arrows or dot indicators to browse
  • Remove — Hover over a thumbnail and click the red X
  • Resize — Drag the handle between the carousel and caption area to adjust the split

On the app:

  • Reorder — Use the left/right arrows below each thumbnail to change the order
  • Remove — Tap the red X on any thumbnail
  • Images appear in a horizontal filmstrip you can scroll through

AI Caption Generation

FLUF can write your Instagram captions for you using AI that actually looks at your images.

  1. Choose a tone from the dropdown:
  • Engaging — Upbeat, community-focused
  • Professional — Clean, brand-appropriate
  • Casual — Relaxed, conversational
  • Funny — Light-hearted, witty
  • Minimal — Short, to the point
  1. Optionally add extra instructions (e.g. "mention free shipping" or "include a call to action")
  2. Click Generate

The AI analyses your carousel images and writes a caption that describes what's actually in the photos, with relevant hashtags included.

You can always edit the generated caption before posting.
