Say More with Less: How Captionizer Makes Visuals Work Harder in Confluence
Adding images to Confluence pages is second nature for many of us, but captioning them? That’s usually an afterthought. It takes time, breaks your flow, and let’s be honest, it’s often skipped altogether.
That’s where Captionizer, a free AI-powered app from our partners at AppFox, steps in.
Captionizer automatically generates smart, consistent captions for images on your Confluence Cloud pages using Atlassian’s Rovo AI. It’s lightweight, free to try, and designed to make your content clearer, more accessible, and easier to navigate, without any manual effort.
🧠 What It Does
Once installed, Captionizer lives inside the Rovo chat panel in Confluence. Just open the agent, ask it to caption your images, and you’ll get a set of AI-generated suggestions you can review, edit, or approve before publishing.
✨ Why It’s Worth Checking Out
Time-saving: No more manually writing captions for every screenshot, diagram, or chart
Clarity first: Adds helpful context that boosts readability and understanding
Global-ready: Built-in multilingual support means captions can reach wider audiences
Consistent formatting: Keeps your documentation polished and on-brand
Accessibility bonus: A big step forward in supporting users who rely on screen readers or accessible content
And the best part? You get 100 free captions per user, per month, so there’s zero risk in giving it a try.
🔍 What to Watch Out For
Every tool has its limits, and Captionizer is no exception. Some things to note:
There’s a 100-caption limit per user each month, which might be a blocker for heavy users
Works best with up to 6 images per captioning request
It requires Rovo to be enabled in your Confluence instance (now included free in Premium and Enterprise Cloud plans since April 2025)
As it’s a relatively new app, there aren’t many public reviews yet, so real-world feedback is still emerging
✅ Best Use Cases
Technical documentation, process guides, architecture diagrams
Knowledge base articles that support multilingual or cross-team collaboration
Teams working toward accessibility compliance (e.g. WCAG standards)
Anyone who wants clean, descriptive visuals without the admin burden
🎯 Final Thoughts
If you regularly publish visual content in Confluence, Captionizer is a clever, no-fuss way to improve the quality of your pages. It takes the chore out of captioning, helps your content land better, and supports accessibility, all while working quietly behind the scenes via Rovo.
We’re excited to see how this evolves, especially as more teams start experimenting with what Rovo can do. Big thanks to the team at AppFox for another thoughtful addition to the ecosystem, and keep your eyes peeled 👀 for an upcoming webinar where we’ll explore this and more together.
