Real 9:16 vertical render from a one-line prompt.
Not a clip. A finished TikTok.
One prompt. A finished TikTok, not a stitch project.
Most AI TikTok tools hand you a single 6-second clip and stop, so you still have to write the script, record the voice, cut the captions, and stitch it in another editor. MakeAIVideo runs the whole pipeline: hook-first script, AI voiceover, multiple scenes, word-by-word captions, ducking music, vertical 1080p render.
Hook-first scripts
Every draft opens with a line built to survive the first three seconds of the For You feed.
Vertical from the start
Pick 9:16 before generating; captions and framing tune to the safe area, no re-crop after the fact.
Captions burned in
Word-by-word captions time to the voiceover and bake into the export, ready to post without sound.
How it works
How the TikTok video generator works
- 01
Drop in your topic and aspect ratio
Type a one-line idea (the topic, the angle, the format) and choose 9:16 vertical for TikTok. Specific prompts produce specific output; if the angle is sharp, the script will be too. The pipeline reads it and starts working immediately.
- 02
AI writes a hook-first script and picks a voice
Your line becomes a paced short-form script that opens with a hook in the first three seconds, then carries through body and close. A natural AI narrator is chosen to match the tone, and you can re-roll the voice later if you want a different read.
- 03
AI generates scenes, captions, and music
Every beat of the script becomes a scene in the visual style you pick (cinematic, anime, claymation, more), and word-by-word captions are timed to the voiceover so the video lands silently in the feed. Background music ducks under the narration automatically; nothing to mix.
- 04
Render vertical 1080p and download
Most short TikToks render in about 90 seconds end to end. A clean 9:16 1080p MP4 lands in your library, watermark-free on a paid plan, ready to upload to TikTok directly or open in the editor to tweak a scene first.

All included
Everything you get in a TikTok render
Voice, captions, music, and 1080p export bundled into every clip.
Native 9:16 vertical
Built vertical from the prompt, not letterboxed from a wide source.
14 visual styles
Cinematic, anime, claymation, and more, applied across every scene.
Word-by-word captions
Eight caption presets, timed to the voiceover and burned into the export.
Studio AI voices
A curated library of natural narrators to match the niche.

Auto-matched tracks that sit under the narration without burying the voice.
Watermark-free 1080p
Clean exports ready to upload directly to TikTok.
What you can ship
A finished vertical clip per prompt, paced for the For You feed.
Faceless content
Build a posting habit without filming yourself. One prompt becomes a fully voiced, captioned, paced vertical video you can publish to TikTok the same day.
Hook-first explainers
Turn 'why X works' or 'how Y is built' into a paced 30 to 60 second vertical explainer. The hook lands in the first three seconds, then the body delivers the payoff before the scroll.
Product POV clips
Frame a feature or launch as a POV-style short, the format that wins on TikTok product discovery. The script writes itself from a one-line brief; the visuals match the feel.
Tutorial shorts
Compress a how-to into 60 seconds of paced narration and matching scenes. Each beat gets its own visual so nothing drags and the steps stay easy to follow.
Trend-responsive content
When a topic spikes, the pipeline turns it into a finished vertical clip in about 90 seconds, fast enough to ride a trend instead of catching it on the way down.
Niche brand voice
Build a recognisable look and voice across every clip in your niche. The visual style, voice, and caption preset stay consistent so the channel reads as one creator, not a grab bag.
If you want to clip up an existing long video, a repurposing tool fits better. This is for TikToks built from scratch.
Best practices
Tips for For-You-feed survival
- Write the prompt around the hook
- Lead with the angle, not the topic. 'A 30-second POV about why TikTok pays less than YouTube' beats 'a video about creator pay' every time; the script inherits the angle from your line.
- Pick 9:16 before generating
- Captions and framing are tuned to the safe area for the ratio you choose; re-cropping a 16:9 render to vertical costs another generation and clips visuals that mattered.
- Aim for 30 to 60 seconds
- Retention drops sharply past 60 seconds on TikTok for most niches. Tight, paced clips outperform longer ones; the pipeline will pace your prompt to fit if you say 'short' in the brief.
- Burn captions in for sound-off viewing
- Most of the feed plays muted in the first second. Word-by-word captions are baked into the export by default; pick a high-contrast preset so they read on busy backgrounds.
- Re-roll one scene, not the whole clip
- If a single scene misses, regenerate just that scene in the editor instead of re-rendering the whole video. Faster and cheaper than starting over.
- Name the format in your prompt
- Say 'faceless explainer', 'POV', or 'tutorial short' in the brief. The pipeline tunes pacing, tone, and visual style to the format you name.

Frequently asked questions
How does the TikTok video generator work?
You type a one-line prompt and MakeAIVideo writes a hook-first script, records an AI voiceover, generates a scene for each beat, times word-by-word captions to the voice, and renders a 9:16 vertical 1080p MP4 ready to upload to TikTok. A short clip is typically ready in about 90 seconds.
How much does it cost?
Plans start at $29/month, with a 7-day free trial on every plan and $0 due today. Cancel any time during the trial and you won't be billed. See pricing.
How long does a TikTok render take?
Most short vertical clips render in about 90 seconds end to end. Longer videos, higher-fidelity styles, and re-rolls add to that, but a typical 30 to 60 second TikTok is ready while you make a coffee.
What aspect ratios and resolution does it export?
9:16 vertical for TikTok, Reels, and Shorts; 16:9 landscape for YouTube; 1:1 square for feeds. Every export is 1080p MP4 with captions baked into the safe area for the ratio you pick.
Is there a watermark on the videos?
No. Every export from a paid plan is watermark-free 1080p MP4, yours to upload to TikTok or anywhere else. Watermark removal isn't gated behind a higher tier.
Can I monetise the videos on TikTok and the Creator Fund?
Yes. Videos generated on a paid plan are yours to use commercially: TikTok Creator Fund, ads, brand deals, monetised channels. The AI scenes are generated, not pulled from a stock library, so there's no third-party licensing question. See the full terms.
Can I edit the TikTok after it generates?
Yes. Every render opens in the built-in editor where you can rewrite captions word by word, swap the voice, re-roll a single scene, or restyle the captions. The default export is built to post as-is if you don't want to tweak.
How is this different from a generic AI TikTok generator?
Most TikTok generators hand you a single short AI clip and stop, so you still write the script, record the voice, cut captions, and stitch it elsewhere. MakeAIVideo runs the whole pipeline (script, voiceover, multi-scene visuals, captions, music) and outputs the finished vertical video you can upload directly.
Can I bring my own script instead of a prompt?
Yes. Script to video narrates your script verbatim over AI scenes, with the same captions and 9:16 export. Use prompt mode if you want the AI to write the words, script mode if you've already written them.
Are captions and music included?
Yes. Word-by-word captions are timed to the voiceover and burned into the export, and background music is auto-matched and ducks under the narration. Nothing to add in post; the clip is ready for the feed.
How long can a generated TikTok be?
Most TikTok-style clips work best in the 30 to 60 second range, where retention is strongest. Longer videos are supported (up to 10 minutes for AI-generated scenes), but for the platform the shorter, paced format tends to outperform.
What happens after my 7-day trial?
Your plan starts billing at its monthly rate at the end of the trial. Cancel any time during the trial for no charge and you won't be billed.
