AI TikTok Video Generator
made for the algorithm.

Write one line of intent. Shortlify produces a viral-ready 9:16 TikTok: hook, script, AI voice, cinematic visuals and beat-synced captions.

TikTok-style vertical ad generated from a single product photo + one-line prompt.
What you get
  • Native 9:16 1080×1920 for TikTok (no cropping, no letterboxing).
  • Hook-first scripts tuned for the first 1.5 seconds of watch time.
  • AI voiceover in 30+ voices, tuned for TikTok pacing and energy.
  • Beat-synced captions with animated styles that match TikTok trends.
  • Built-in music library — swap to any trending audio after download.
  • Batch generate 10 variations of the same idea to A/B test hooks.
How it works
  1. 01
    Step 1

    Describe the TikTok in one line

    Tell Shortlify what the TikTok should be about — a story, a tip, a mystery, a product pitch. The AI writes a hook-first script tuned for vertical consumption.

  2. 02
    Step 2

    Pick voice + style

    Match your brand with a voice (energetic, calm, narrator, creator-like) and a visual style (cinematic, illustrated, meme, POV). The AI locks your character across scenes so the TikTok feels made, not assembled.

    Step 3

    Render and post

    Export the finished 9:16 MP4 with captions burned in. Replace the soundtrack with any trending TikTok audio in-app, then post directly. Total time: under 15 minutes from idea to live.

FAQ
Will my TikTok look AI-generated?
Only if you pick that aesthetic. Shortlify supports cinematic, photoreal, illustrated, meme-style and UGC-style visuals. Most of our viral clips pass for "made in CapCut" — the AI layer is invisible in the final output.
Can I use trending TikTok audio?
Our built-in music library is fully licensed for posting. If you want a specific trending sound, render the MP4 and swap the audio in TikTok's own editor — the captions and visuals stay synced.
Does TikTok's algorithm penalize AI content?
TikTok recently added AI-content labels (self-applied) but does not deprioritize AI videos in the For You feed. Hook quality, completion rate, and shares matter 100x more than "was this AI."
How do I keep a consistent character across a series?
Upload a reference photo once. Shortlify's character-lock system keeps the face, outfit and vibe consistent across episodes — essential for building a recognizable AI creator persona.
Can I post directly to TikTok from Shortlify?
Currently you export the MP4 and upload via TikTok's app (takes 10 seconds). Direct publishing is on the roadmap for Q2 2026.
Is the watermark removed on free plans?
No watermark on any plan — even the free tier exports clean MP4s. You own every video you generate and can monetize them however you like.
