"I post 3x per day on TikTok using EchoAI. Went from 5K to 250K followers in 6 months. The AI captions are indistinguishable from my manual captions."
"EchoAI lets me focus on creating content, not editing. I repurpose every YouTube video into 30+ Reels. My Instagram grew 10x in 4 months."
"The viral moment detection is scary good. AI found a clip that got 2M views that I would have never picked manually. Worth every penny."
EchoAI analyzes your previous captions, word choice, punctuation style, and tone patterns. The more clips you create, the better it gets at mimicking YOUR unique voice. By clip 10-20, the AI-generated captions will be nearly indistinguishable from your manual ones.
We support all major video formats (MP4, MOV, AVI, MKV, WebM) and can handle files up to 5GB. Upload your long-form content in any format, and we'll automatically create vertical 9:16 clips optimized for TikTok and Instagram Reels.
Unlimited! From a 30-minute video, you can typically get 20-50 high-quality viral moment clips. From a 2-hour podcast or livestream, you can easily generate 100+ clips. There's no limit to how many clips you can create per video.
Yes! Choose from multiple caption styles: Bold (centered, word-by-word pop), Modern (clean, eye-catching), Classic (traditional, readable), Minimal (simple, distraction-free), and Neon (large, attention-grabbing). Customize fonts, colors, positioning, and animation timing.
Viral moment detection automatically finds the most engaging moments using AI analysis. Prompt-based clipping lets you tell the AI what to find (e.g., "funny moments", "controversial takes", "inspirational quotes"). Use both together for maximum clip variety and output.
Most videos are processed in 2-5 minutes. A 30-minute video typically takes 3 minutes to analyze and generate clip suggestions. You can then review and export clips immediately. Batch exporting 100 clips takes an additional 5-10 minutes.
