Merchmint — Batch AI Media for Sellers

Queue hundreds of prompts in your own Google Flow account, then auto-upscale and auto-download every result.

Merchmint works with your own Google Flow account. You must be signed in to Google Flow with a project open. Merchmint submits your prompts through that session — exactly as if you clicked Generate yourself — then upscales and saves the results. It does not provide AI generation of its own, and it does not give you access to anything your Google account does not already have. Every generation counts against your own Google quota. What it does • Queue hundreds of prompts and run them unattended • Batch image generation (Nano Banana Pro, Nano Banana 2, Nano Banana 2 Lite) • Batch video generation (Veo 3.1 Lite / Fast / Quality, Omni Flash) • Assign a different reference image or start frame to each prompt • Chain generations so each result feeds the next • Automatic 2K upscaling and downloading with numbered filenames • ZIP export, regenerate, and turn any image into a video Free and Pro The free tier includes 30 prompts per day, no card required. Merchmint Pro removes the daily cap for $3/month or $29/year. Some options need a Google AI Ultra subscription 4K upscaling, the lower-priority Veo models, and 4-second and 6-second durations are provided by Google to Google AI Ultra subscribers. Merchmint cannot unlock them; where they are unavailable they are shown as locked with the reason. Independence Merchmint is an independent tool. It is not affiliated with, endorsed by, or sponsored by Google. Google Flow, Veo and related marks belong to Google.
