Smart, colorful, offline, and designed to make your content go viral.
1. ViralSim: The Offline Virality Simulator
Simulate how viral your idea could be.
This score is calculated by multiplying the length of your idea by 2, capped at 100. Longer, engaging ideas are considered more viral.
2. HookForge: The Hook Strength Calculator
Test the strength of your hook line.
The hook score is calculated as 50 plus the number of characters in your hook, maxing at 100. Stronger, longer hooks get higher scores.
3. Thumbnail Impact Estimator
Estimate the impact of your thumbnail.
Thumbnail impact is calculated by counting the words in your description and multiplying by 10, capped at 100. More descriptive thumbnails score higher.
4. Attention Momentum Calculator
Predict how well your content retains attention.
Retention is estimated by subtracting 5% for each shot from 100%. Fewer shots generally keep the audience more engaged.
