Whether you’re creating YouTube videos, TikToks, Instagram Reels, or training content, writing a video script from scratch can take hours. AI tools like ChatGPT, Claude, and Gemini can help you generate solid first drafts in minutes—complete with hooks, structure, and calls to action.
Here’s how to use AI to write video scripts quickly, along with prompts and tips that actually work.
Step 1: Choose Your AI Tool and Set the Context
All three major AI assistants—ChatGPT, Claude, and Google Gemini—can write video scripts. Each has strengths:
- ChatGPT (GPT-4): Great for conversational, punchy scripts and social media content.
- Claude: Excels at longer-form content and nuanced tone control.
- Gemini: Strong at research-heavy scripts and pulling in current information.
Start by giving the AI context about your video. Instead of asking for “a video script,” tell it the platform, length, audience, and goal.
Example prompt: “Write a 90-second YouTube script for small business owners explaining how to use AI to automate customer service emails. Use a friendly, approachable tone. Include a hook in the first 5 seconds and a call to action at the end.”
Step 2: Specify the Format and Structure
Video scripts need visual and audio cues. Ask the AI to format the script with separate columns or sections for dialogue, on-screen text, and B-roll suggestions.
Example prompt: “Format the script in two columns: the left column should have the narration, and the right column should suggest visuals or B-roll for each section.”
You can also request timestamps, especially for longer videos. This helps during editing and keeps your pacing tight.
If you’re writing for short-form video (TikTok, Reels, YouTube Shorts), ask for a hook in the first 3 seconds and keep the total length under 60 seconds. AI tends to overwrite—be explicit about brevity.
Step 3: Refine Tone, Style, and Specific Phrases
AI-generated scripts can sound generic. To fix this, give examples of your style or specify phrases to avoid.
Useful follow-up prompts:
- “Rewrite this in a more casual tone, like I’m talking to a friend.”
- “Remove any jargon and make it sound natural when read aloud.”
- “Add a personal anecdote in the intro to make it more relatable.”
- “Make the call to action stronger and more specific.”
Read the script out loud. If it sounds stiff or robotic, paste it back into the AI and say, “Make this sound more conversational and less formal.”
Step 4: Generate Variations for A/B Testing
If you’re creating content for social media, try multiple versions of your script—especially the hook. Ask the AI to generate three different openings, then test which one performs best.
Example prompt: “Give me five different hook options for the first 5 seconds of this video script. Make them punchy and curiosity-driven.”
You can also ask for different lengths. For example, request a 60-second version and a 3-minute version of the same concept, then choose based on your platform and audience.
Pro Tips for Better AI Video Scripts
Here are a few tricks that improve results every time:
- Specify the narrator: If you’re writing for yourself, say “Write this as if I’m speaking directly to the camera.” If it’s a voiceover, mention that.
- Include transitions: Ask for smooth transitions between sections, especially in how-to or listicle videos.
- Request on-screen text suggestions: AI can suggest captions, titles, or key phrases to display as text overlays.
- Iterate fast: Don’t expect perfection on the first try. Use follow-up prompts to tweak tone, pacing, and structure.
AI won’t replace your creative voice, but it will eliminate the blank-page problem and give you a strong foundation to edit and personalize.
