You can automate up to 80% of YouTube video creation using AI — covering scripting, voiceover, video assembly, thumbnail generation, title/description writing, and uploading. The stack: Topic research → AI script (assisters.dev) → ElevenLabs voiceover → Remotion/HeyGen video → DALL-E thumbnail → YouTube Data API upload. A fully automated faceless YouTube video can go from idea to published in under 30 minutes.
Use Make to run weekly topic research:
POST https://assisters.dev/api/v1/chat/completions
Authorization: Bearer ${ASSISTERS_API_KEY}
{
"model": "assisters-chat-v1",
"messages": [
{
"role": "system",
"content": "You are a YouTube content strategist. Identify 5 high-potential video topics for the given niche based on search demand and low competition signals. Return JSON: [{ title, keyword, estimated_search_volume, angle, hook }]"
},
{
"role": "user",
"content": "Niche: AI productivity tools for freelancers. Current month: April 2026. Focus on how-to and comparison content."
}
]
}
Add to a Notion content calendar database for weekly review.
For each approved topic, trigger script generation:
{
"role": "system",
"content": "Write a YouTube video script with: Hook (30 sec), Intro with credibility (60 sec), Main content in 5 chapters with timestamps, CTA (30 sec), Outro (20 sec). Total length: 1200-1500 words. Format with [CHAPTER X: Title] markers. Include B-roll notes in [B-ROLL: description] format."
}
{
"role": "user",
"content": "Script for: ${videoTitle}
Keyword: ${primaryKeyword}
Target audience: Freelancers who want to save time with AI tools
Tone: Practical, no hype, direct"
}
Pass the script (without B-roll notes) to ElevenLabs:
POST https://api.elevenlabs.io/v1/text-to-speech/${voiceId}
xi-api-key: ${ELEVENLABS_API_KEY}
{
"text": "${scriptText}",
"model_id": "eleven_multilingual_v2",
"voice_settings": { "stability": 0.5, "similarity_boost": 0.75 }
}
The response is an MP3 file. Save to cloud storage (R2, S3, or Supabase Storage).
Option A — Remotion (code-based, most control): Remotion is a React-based video generation library. Write a template once, render programmatically:
// In your Remotion composition
<Sequence from={0} durationInFrames={audioDuration * fps}>
<Audio src={voiceoverUrl} />
<BackgroundVideo src={`${brollUrl}`} />
<Subtitles captions={whisperCaptions} />
</Sequence>
Trigger renders via: npx remotion render --props='${JSON.stringify(videoProps)}'
Option B — Pictory AI or InVideo AI (no-code): Use their APIs or automations to assemble stock footage videos from scripts automatically. Both have native Make integrations.
Option C — HeyGen (AI avatar videos): For talking-head style videos without recording yourself:
POST https://api.heygen.com/v2/video/generate
X-Api-Key: ${HEYGEN_API_KEY}
{
"video_inputs": [{
"character": { "type": "avatar", "avatar_id": "${avatarId}" },
"voice": { "type": "elevenlabs", "voice_id": "${voiceId}", "input_text": "${script}" }
}],
"dimension": { "width": 1920, "height": 1080 }
}
POST https://api.openai.com/v1/images/generations // or assisters.dev endpoint
{
"model": "dall-e-3",
"prompt": "YouTube thumbnail: ${thumbnailConcept}. Bold text: '${shortTitle}'. High contrast, eye-catching, professional.",
"size": "1792x1024"
}
Add text overlay via Canva API or Sharp (Node.js image processing library).
{
"role": "user",
"content": "Write YouTube metadata for this video:
Primary keyword: ${keyword}
Script summary: ${excerpt}
Provide: 3 title options (under 60 chars), description (250 words, keyword in first line, chapters included), 15 tags."
}
POST https://www.googleapis.com/upload/youtube/v3/videos?uploadType=resumable&part=snippet,status
Authorization: Bearer ${YOUTUBE_ACCESS_TOKEN}
{
"snippet": {
"title": "${selectedTitle}",
"description": "${description}",
"tags": ${tags},
"categoryId": "26"
},
"status": {
"privacyStatus": "scheduled",
"publishAt": "${scheduledPublishTime}"
}
}

Template 1 — Faceless AI YouTube channel (full auto) Weekly cron → AI generates 5 topics → Approved topic webhook → Script → ElevenLabs voiceover → Pictory video → DALL-E thumbnail → AI metadata → YouTube upload scheduled for Tuesday 9am
Template 2 — Human-narrated channel (semi-auto) Blogger publishes article → Webhook → AI generates YouTube script from article → Save to Notion for recording → After recording upload trigger → AI generates thumbnail and metadata → Upload to YouTube
Template 3 — Shorts factory Daily cron → AI generates 3 short-form (60-second) scripts from top blog posts → ElevenLabs VO → Remotion renders vertical 9:16 video → Upload to YouTube Shorts
Manual video production per video:
Automated (faceless, AI-driven):
For a channel publishing 4 videos/week: 20–32 hours saved per week.
Automating YouTube video creation is no longer experimental — it is a legitimate production strategy used by thousands of channels. Start with scripting and metadata automation, add voiceover next, and build toward full video assembly as your workflow matures.
