SepiaLab
Turn one product photo into UGC video ads you can test
SepiaLab turns a product photo and a short brief into a series of ready-to-post UGC video ads, each built on a different hook. The full pipeline runs end to end: script, voiceover, b-roll, captions, edited 9:16 video. Built for creative testing: generate a batch, keep the winner, go deeper in that direction. Pay as you go, no subscription, no filming.
Hey Product Hunt! I'm Jonathan, solo founder of SepiaLab (Montreal).
I built this because creative testing is broken for small DTC brands. Testing 10 ad angles means hiring creators, shipping products, waiting weeks, and paying hundreds per video. Most small brands just don't test. They run one ad and pray.
SepiaLab flips that: upload a product photo, describe your product, and you get a series of UGC-style video ads, each one built on a different hook. Script, voiceover, b-roll, captions, edited 9:16, the whole pipeline runs end to end. You test the batch, keep the winner, generate more in that direction.
Two things I decided early: pay as you go (no subscription, you pay when you test) and no actor marketplace to manage.
I'd love brutally honest feedback on two points: the realism of the videos (watch one with sound on) and the pricing model. If you run ads for a DTC brand, tell me what would stop you from using this tomorrow.
The hook variety was way better than I expected, each one felt like a different angle instead of just word swaps. Loved that it spits out the captioned vertical cut ready to post, no editing needed.
Love the pay-as-you-go model and the hook variation approach, super practical for testing. One thing that would help me a lot: let me upload a few of my past winners so the system can match the style, pacing, and tone that already works for my brand instead of guessing from scratch.
Really like the batch-and-test approach for hooks. One thing that would save me time: let me upload my own voice sample or pick from a few preset voices so the voiceover matches my brand tone across all variants instead of getting a generic one each run.
A batch of static product photos would be a nice starting point if you don't even have a hero image ready, like pulling lifestyle shots from a URL or pulling the hero image automatically from a Shopify product page.
Love that it generates multiple hooks in one shot, that's exactly what slow creative testing needs. The batch-then-iterate flow feels like it was designed by someone who actually runs ads.
Really cool tool for solo founders trying to test creative without a big team. One thing I'd love to see is the option to plug in a competitor's ad URL so SepiaLab can pull the hook structure and remix it into a batch of variants for your product, that would save a ton of manual research time.
honestly love that it spits out multiple hook variations in one go instead of making you babysit one script. feels like the team actually understands how creative testing works in practice.
the hook variety is genuinely impressive, I got like five pretty different angles from one product shot and the captions actually looked clean on the first pass
