An AI YouTube video maker can take you from a script to a finished video, but the tool is only one step. The result depends on your idea, your script and how you finish the video. This guide walks through the whole workflow, with prompts and a checklist, so your videos feel original and follow YouTube’s rules.
Step 1: Choose an idea and an angle
Pick one topic and one point of view. “How to budget in your first year of work” is stronger than “money tips”. Ask yourself what your video says that the top results don’t. If you can’t answer, change the angle.
Give me 10 video ideas about [niche] for [audience]. For each one, explain what makes the angle different from the most common videos on the topic.
Step 2: Write the script yourself, then improve it with AI
Write your own outline, then use AI to tighten it. Keep one idea per video, open with the point of the video and end with a clear next step.
Here is my outline for a [length]-minute YouTube video: [outline]. Write a script in a friendly, clear voice. Start with a hook that states what viewers will learn, and keep sentences short.
Check every fact in the script before you generate anything, because errors are costly to fix after rendering.
Step 3: Choose the voice
Pick a voice that suits your audience and keep it consistent. Fliki has a large library of AI voices in many languages, and HeyGen and Synthesia pair voices with an AI presenter. Voice cloning is available on some plans, but only clone your own voice, never someone else’s. See our reviews for each tool’s plans.
Step 4: Generate the video
Choose the tool that matches your format.
Stock footage and voiceover: Pictory or Fliki.
Prompt to draft video: InVideo AI, keeping an eye on credits.
AI presenter: HeyGen or Synthesia.
Original B-roll clips: Runway.

Step 5: Edit it so it feels like your channel
Replace generic scenes, fix awkward lines, add your own examples and make sure the visuals match what you say. A short intro works better than a long one, and most script-to-video tools can build one from a single line of text. Add captions and keep the pacing tight.
Step 6: Make the thumbnail
A custom thumbnail should be 1280 × 720 pixels in a 16:9 ratio and under 2 MB, as a JPG or PNG. Custom thumbnails require a verified channel. Use a clear image and a few words, and make sure the thumbnail and title promise the same thing.
Step 7: Write the title, description and tags
Titles can be up to 100 characters, but search results show about 70, so put the main keyword first. Descriptions can be up to 5,000 characters, and the first lines matter most. Tags have a combined limit of 500 characters and carry little ranking weight, so use a few focused ones. Our guide to AI title and description prompts has templates for all three.
Step 8: Check the disclosure, then upload
If your video includes realistic synthetic content, such as an AI voice or AI visuals presented as real, use the altered or synthetic content setting in YouTube Studio when you upload. Disclosure doesn’t by itself limit your video’s eligibility to earn.
A final checklist
Before you publish, check that the video:
- has an original idea or angle
- has been fact-checked line by line
- sounds like your channel, not a template
- has a thumbnail and title that match
- has the right disclosure setting
- is different from your last video
What to avoid
Mass-producing near-identical videos. YouTube’s rules target mass-produced, repetitive content.
Publishing raw tool output. Edit every video.
Cloning real people’s voices or faces. Don’t impersonate anyone.
Giving health, legal or financial advice through an AI persona. One 2026 guide reports this isn’t monetizable at all. Read our guide to monetizing AI-generated YouTube videos for the details.
