🎥 How Digen.ai Creates the Best AI TikTok Videos in 2025
Step 1: Input Your Message – 3 Flexible Ways
You’re not locked into one workflow. Choose what fits your style:

→ AI selects the ideal voice (gender, tone, language)
→ Generates perfectly timed lip movements
→ Adds auto-captions in your brand font
✅ Supports 20+ languages, including English, Spanish, Japanese, Korean, French, and Arabic.
🎤 Record Live (Mobile-First)
Open the Digen.ai app → tap mic → speak your script.
