AI Content Generation
Generate captions, hooks, scripts, titles, and thumbnail ideas tailored to each platform's algorithm — no copywriting experience needed.

Generate captions, hooks, scripts, titles, and thumbnail ideas tailored to each platform's algorithm — no copywriting experience needed.
Every output is rated 1–100 across Hook, Clarity, Engagement, Platform Fit, and SEO — so you know how likely it is to go viral before you post.
Each platform gets its own AI model context. TikTok hooks aren't YouTube hooks — and ViralSpark knows the difference.

Everything you need to know about ViralSpark.
ViralSpark is an AI-powered content generator for TikTok, Instagram, YouTube, and Facebook. It creates viral captions, hooks, and video scripts in seconds — and rates every output with an AI Viral Score so you know what's worth posting.
Yes. You get 2 free content generations per platform — no account needed. Upgrade to Pro for unlimited generation across all platforms at $9.99/month or $64.99/year (save 46%).
No account is required for free or iOS use. The web app only asks for your email if you subscribe to Pro — and that's used solely to manage your Stripe subscription. No password, no profile.
ViralSpark supports TikTok, Instagram, YouTube, and Facebook. Each platform has its own AI context — YouTube can generate Titles and Thumbnail text, while TikTok, Instagram, and Facebook focus on captions, hooks, and scripts.
ViralSpark generates Captions, Hooks, and full Scripts for all platforms. For YouTube, it also generates Titles and Thumbnail copy. You can choose from 6 tones: Professional, Inspirational, Storytelling, Casual, Educational, and Funny.
Every generated output is rated out of 100 by AI across five dimensions: Hook Strength, Clarity, Engagement Potential, Platform Fit, and SEO/Keywords. You also get improvement tips and a label — from Weak to Viral — so you know exactly what to fix before posting.
Yes. AI-generated content from ViralSpark is yours to use for personal and commercial social media purposes. We don't retain ownership over outputs. Always review content before publishing to ensure it meets platform guidelines.
After generating content, you'll see an Improve Content button. The AI re-writes the output targeting the specific weak areas from your viral score — lifting Hook Strength, tightening Clarity, or adding better keywords — and scores it again so you can see the difference.
Your inputs (topics, keywords) are sent to our AI backend for processing only — they are not stored after your content is generated. Generation history is saved locally on your device, not on our servers. See our Privacy Policy for full details.
iOS: Go to your Apple ID → Subscriptions → ViralSpark and cancel anytime. Web: Open the Account panel in the web app, tap Manage Billing, and cancel via the Stripe portal. Your Pro access stays active until the end of the billing period.
Both offer the same AI generation and scoring. The iOS app stores everything locally with no account needed. The web app runs in your browser and uses Stripe for Pro subscriptions (instead of Apple IAP). The web app also requires your email to restore Pro access across devices.
Free to download. No account needed. Just open it and create viral content.
