FlowBatch

Batch-generate images and videos in Google Flow: prompt queue, reference mapping, auto upscale and auto-download.

🚀 FlowBatch turns Google Flow into a batch machine. Paste a list of prompts, press Start, and walk away. FlowBatch generates every prompt inside your own Flow tab, downloads each result to your computer and upscales it, while you do something else. 📖 Full guide with screenshots: https://flowbatch-server.flowbatch-server.workers.dev/guide ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ⚡ HOW IT WORKS (about one minute) ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 1️⃣ Open flow.google.com and open a project. 2️⃣ Click the FlowBatch icon.

Your prompts, reference images and results go only to Google, exactly as when you use Flow by hand. They are never sent to us. Our server only sees your Google sign-in (name, email), how many prompts you ran, and your plan. Payments are handled by Payment Gateway, so we never see card details. FlowBatch never sees your Google password. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 💳 PLANS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🎁 NOW: unlimited and free for everyone during the launch period. After launch: 24 hours unlimited when you first sign in, then 30 prompts a day free. The Unlimited plan (monthly or yearly) removes the daily limit. Cancel any time. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ❓ QUESTIONS PEOPLE ASK ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Q: Do I need a paid Google account? A: You need a Google account that can use Google Flow. Video generation spends your own Flow credits, and 4K needs Google AI Ultra. Those come from Google, not from us. Q: Can I close the tab while it runs? A: The Flow tab must stay open, because the work happens inside it. You can switch to other tabs and use your computer normally. Q: Where do my files go? A: Your normal Downloads folder, inside the sub-folder you name in the panel. Q: What if a prompt fails? A: It is marked failed, the log shows why, it is refunded to your count, and you can retry only the failed ones. Q: Is this allowed? A: FlowBatch does the same actions you would do by hand, in your own browser. It is an independent tool, not affiliated with or endorsed by Google, and you are responsible for following Google's terms. Use Balanced or Slow speed if Google throttles you. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 💬 SUPPORT ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ If something does not work as expected, please email us BEFORE leaving a review: flowbatch267@gmail.com Open the Logs tab, press Copy, and paste the log into your message.
