What is an AI product explainer?

An AI product explainer is a short video—usually 30–90 seconds—generated or heavily assisted by AI that shows how your product works using screen capture, avatar narration, and automatic captions.

Featured snippet: An AI product explainer is software that converts a script or product walk-through into a polished demo video using synthetic voice, templated visuals, and auto-editing—no camera or editing suite required.

How to use it (step-by-step)

Execute this workflow before Friday:

1. Clarify goal
   One sentence: “After watching, the viewer will ____.”Pick a single metric: sign-up, book-a-call, or feature adoption.
2. Outline & script
   Hook (problem) ≤ 3 secondsSolution (your product) ≤ 20 secondsProof (screen capture) ≤ 30 secondsCTA ≤ 7 secondsKeep total word count ≤ 120 (≈45–60 seconds).
3. Choose tool
   Need interactive clickable demo? → Storylane.Need avatar + multi-language? → Synthesia.Repurposing long demo or webinar? → Vidyo.ai.
4. Record/import assets
   Capture only the exact clicks that solve the pain point; skip settings pages.1080p minimum; mute system audio to avoid background noise.
5. Create voiceover
   Use built-in synthetic voices for speed; upload own only if you have a quiet room + good mic.
6. Edit for clarity
   Zoom on clicks; highlight cursor.Delete “ums” and pauses—AI tools auto-detect.
7. Add captions & branding
   Upload logo hex colors; enable open captions (85 % of social plays are silent).Check contrast ratio for accessibility.
8. Export & host
   MP4 for website; GIF for email.Host on Wistia or Vimeo so you can swap video without changing URL.
9. Measure
   Aim for 70 % retention at 15 seconds; <50 % means hook is weak.Track CTA clicks via UTM or event pixel.

Founders often miss this — viewers decide to keep watching or bounce in the first 3 seconds, so spend 50 % of your time crafting the opening hook, not the closing logo.
