Show HN: Mersel.ai – batch AI tool for product photo and video generation

[wujosephjw]

I’ve been building an GenAI project called Mersel. It helps people create or edit photos and videos in batches, so they can make a full set in one click instead of repeating the same steps.

I’m using Nano Banana and Veo 3.1 APIs. Nothing new technically, but I’ve been focusing on making them work faster and more efficiently for batch creation, which feels more practical for workflows that deal with a lot of visuals.

I’m building it with ecommerce sellers in mind since they often need to produce a large amount of product content quickly. I have a few paying users, still early, and I’m trying to learn what actually matters in their workflow and where current AI tools fall short.

Would love any feedback, thoughts, or ideas from others who have worked on GenAI pipelines or bulk generation tools.

Cheers

Nice work! Batch generation is underserved for sure.

One question: how do you handle consistency across generations? With Veo's non-deterministic nature, keeping 50 product photos stylistically coherent seems tricky.

thanks mate! Consistency is indeed a problem. The only way in my head to solve it atm is to include similar style image input if you are doing image-to-image, image-to-video gen.
