Quick Answer
You can produce 3-5 Instagram Reels per day using AI by scripting in ChatGPT, voicing with ElevenLabs, editing in CapCut AI, and using Metricool to find trending audio.
- Script → voiceover → edit → caption → post in 4 steps
- Use 3-second hooks to beat the 8-second attention span
- Match trending audio within 24-48 hours for reach spikes
What You'll Need
- Instagram Creator/Business account
- Assisters or ChatGPT for scripts
- ElevenLabs (free tier) for voiceovers
- CapCut mobile app (free) for editing
- Metricool or Trendpop for trending audio discovery
Step 1: Research Trending Hooks in Your Niche
Open Instagram Explore → search your niche keyword → note the top 5 Reels with >100k views. Copy their first 3 seconds (the hook structure), not the content.
Step 2: Generate 5 Scripts With AI
Prompt: "Write 5 Instagram Reel scripts about [topic] for [audience]. Each 30 seconds, with a 3-second hook, 4 value points, and a CTA. Format: Hook | Body | CTA." Pick the top 2.
Step 3: Create Voiceover in ElevenLabs
Sign in at elevenlabs.io → Voice Lab → pick "Rachel" or clone your own voice (paid). Paste script → generate → download MP3. Free tier = 10,000 chars/month.
Step 4: Edit in CapCut
Open CapCut → New Project → import clips + MP3 → auto-captions (Text → Auto Captions) → add trending audio at 15% volume under voiceover. Export at 1080x1920, 30fps.
Step 5: Write Captions + Hashtags With AI
Prompt: "Write an Instagram caption for a Reel about [topic]. 125 chars, hook line break, 5 niche hashtags + 5 broad hashtags." Post at 11am-1pm or 7-9pm local time.
Step 6: Analyze and Iterate
After 48 hours, check Insights → note retention graph. If <50% watched past 3 seconds, rewrite the hook. Double down on what hits 65%+.
Common Mistakes to Avoid
- Using stock AI voices that sound robotic — clone your own voice instead
- Ignoring trending audio (kills reach by 60%+)
- Captions longer than 125 characters (truncates in feed)
- Posting raw AI scripts without rewriting for your voice
- Uploading in wrong aspect ratio (must be 9:16)
