User-generated content consistently outperforms brand-produced creative across every major platform. The reasons are well-established:
The problem has always been scale. Finding creators, negotiating rates, briefing, waiting on deliverables, reviewing, revising — a single UGC campaign can take weeks and cost thousands. AI UGC collapses that timeline to minutes.
AI UGC is a talking-head video generated entirely from:
The AI synthesises the voice from your script, then uses lip-sync technology to animate the avatar's mouth and facial expressions to match the audio. The result is a video that looks and sounds like a real person talking directly to the camera about your product.
A brand selling a skincare serum can generate a 30-second "creator review" video where a smiling person says:
*"I've been using this serum for two weeks and honestly? My skin has never looked better. The texture is incredible and it actually absorbs — unlike everything else I've tried. I got mine from Sellable's sample — link in bio."*
The voice is realistic. The lip movement matches. The framing looks like a creator video. The whole thing took 4 minutes to generate.
Step 1 — Write your script
Keep it conversational. Use contractions ("I've been", "it's actually"). Add emotion tags like `[excited]`, `[laughs]`, or `[whispers]` for natural delivery variation. Aim for 30–60 seconds (150–300 words).
Sellable's platform turns a single product photo into studio-quality images, cinematic video, and on-brand campaigns — generated, refined on the canvas, and published straight to your store.
Step 2 — Choose a voice
Select a voice that matches your target demographic and brand tone. Voices are available in multiple languages and regional accents. You can preview before generating.
Step 3 — Select your avatar
Upload a clean, well-lit photo of a person looking slightly toward the camera. The better the input photo, the more realistic the output animation. Sellable's library includes pre-cleared stock avatars if you don't have your own.
Step 4 — Generate
The AI runs two processes simultaneously: voice synthesis (ElevenLabs) and lip-sync animation (LatentSync). A 30-second video typically completes in 60–90 seconds.
Step 5 — Review and iterate
Watch the output and check lip-sync accuracy, voice naturalness, and pacing. If needed, regenerate — small prompt adjustments can significantly improve delivery.
AI-generated content is becoming increasingly regulated. A few principles to follow:
When used transparently, AI UGC is simply a more efficient form of brand storytelling. The message is yours; the medium is AI.
