Gather material from links, videos, and posts
Extract useful material from articles, YouTube, TikTok, Instagram, X, Xiaohongshu, podcasts, or ordinary webpages, then turn long content into swipe-friendly structure.
Instagram Carousel Maker from source material to publish
More than a template picker. Give Kollab a topic, article, YouTube video, competitor post, or product note and it will plan the carousel, generate Instagram-ready slide images, and write the post copy.
Not just slide templatesa full content workflow
Most ranking tools emphasize templates, free starts, quick downloads, and AI drafts. Kollab is built for creators and teams who need source research, generation, review, and publishing in one flow.
Generate Instagram-native slide images
Default to 4:5 1080×1350, or create 1:1 and continuous-style carousels. Kollab can use GPT Image 2 and Nano Banana for still images, plus video models when the carousel needs Reel extensions.
Write captions, hashtags, and publish
Each carousel includes a hook, body copy, CTA, and 8-15 hashtags. After Instagram is connected, Kollab can publish the finished assets and return the public link.

Frequently asked questions
How is Kollab different from a carousel template tool?+
Template tools start with layout. Kollab starts with the content workflow: gather source material, plan the slide structure, generate visuals, write captions and hashtags, and keep everything editable in one task.
Can I start for free?+
Yes, you can open a prepared Kollab task from this page. Image, video, or publishing capacity depends on your plan, model usage, and connector status.
What sources can I use?+
Use topics, product briefs, articles, webpages, YouTube videos, podcasts, TikTok, Instagram, X/Twitter, Xiaohongshu, Bilibili, and other public material.
What size should Instagram carousel slides be?+
Common sizes are 1080×1350 for 4:5 portrait and 1080×1080 for square. Kollab defaults to 4:5 because it takes more feed space, but you can request square, seamless, or panorama output.
How many slides can an Instagram carousel have?+
Instagram supports up to 20 photos or videos in one carousel post. Kollab can plan 3, 5, 7, 10, or more slides while keeping each slide readable.
Can it make seamless Instagram carousels?+
Yes. Ask for a continuous background, panorama, horizontal story, or grid-style carousel. Kollab will plan the visual flow and generate separate uploadable images.
Does it generate captions and hashtags?+
Yes. Kollab creates a first-line hook, caption body, CTA, and 8-15 Instagram hashtags. You can ask for a brand, creator, or sales tone.
Can Kollab publish to Instagram?+
If your workspace has a connected Instagram connector, Kollab can publish after you confirm and return the real permalink. If it is not connected, it will ask you to authorize first.
