How the Post Optimizer Works
The SlyKiwi Post Optimizer scores your Fansly post captions from 0 to 100 based on what actually drives engagement. It checks caption length, emoji usage, call-to-action strength, and how well your tags match your content. Instead of publishing and hoping for the best, you can see exactly what to improve before hitting post.
The scoring model is built on analysis of over 1 million public Fansly posts. It identifies patterns that separate high-performing captions from ones that get ignored — things like optimal text length, hook placement, and tag relevance. Each suggestion is specific and actionable, not generic advice.
Write your caption, add your tags, and watch the score update in real time. The tool highlights which sections need work and what changes would improve your reach. It's free, works in your browser, and doesn't require Fansly credentials.
FAQ
The score (0-100) reflects how well your caption follows patterns found in high-performing Fansly posts. It factors in text length, emoji balance, hook strength, tag count, and tag-to-content relevance. A score above 70 means your post is well-optimized for discovery and engagement.
Yes. Use the tag search below the caption field to add tags. The optimizer scores your caption and tags together, since tag relevance is a major factor in post performance. You can also use our Tag Generator to find the best tags first, then paste them here.
The scoring and tag suggestions are completely free. Caption rewrites powered by AI are available through early access — create a free account and request access from the tool page.
Top-performing captions on Fansly tend to be 50-200 characters, include 1-3 emojis, start with a hook that grabs attention, and pair well with 8-12 relevant tags. Avoid walls of text, excessive hashtags, or generic phrases that don't match your content niche. The optimizer checks all of these factors automatically.
