Why I built it

One AI video in Flow can mean 30+ scenes. Every scene was the same routine, so I automated the routine and kept the creative part.

Before: per scene, by hand

  1. Paste the prompt
  2. Pick the character and the voice
  3. Choose model, ratio and length
  4. Click Generate and wait
  5. Download, then rename the file to its timecode

× 30 scenes, with mistakes when the files get out of order.

With AutoFlow

Paste or import all scenes, press Start, come back to a folder of clips named 0-00.mp4, 0-08.mp4, 0-16.mp4… plus a report of anything that needs a retry.

1 click

instead of ~150 clicks for a 30-scene video

What it does

Built for creators who make long videos and image series in Google Flow.

🎬

Prompt queue

Text to video, frames to video, ingredients, text to image and image editing, with Veo 3.1, Omni and Nano Banana models.

📋

Import from Sheets

Paste a table with tag, prompt, character and voice columns. Templates like {character} {action}, cinematic fill the rest.

🗂️

Files in order

Start a prompt with #0:04 and the clip saves as 0-04.mp4, in a folder per project, with an optional caption file.

🎭

Characters & voices

Picks @Character and the voice by name. Set a voice, model or ratio for just one prompt with a short line on top.

⏯️

Pause, resume, recover

Pause after the current scene. If Chrome closes mid-batch, continue from where it stopped instead of starting over.

📊

Run report

Done, failed and time per scene, “Retry failed only”, and a CSV shot list for your editor. Live time-left estimate while it runs.

🔔

Walk away

A desktop notification and a chime when the batch is finished.

🩺

Self-check

After a Flow update, one button shows which controls AutoFlow can still find, and where to fix them.

🇮🇳

English or Hinglish

Switch the panel to Hinglish (Roman Hindi) in Settings.

Install in 2 minutes

AutoFlow isn't on the Chrome Web Store yet, so it's installed from the ZIP.

  1. Download the ZIP and unzip it (right-click → Extract All).
  2. Open chrome://extensions and turn on Developer mode (top right).
  3. Click Load unpacked and choose the folder that contains manifest.json.
  4. Pin Ajay AutoFlow from the puzzle-piece menu, open flow.google.com and click the icon.
  5. In Chrome Settings → Downloads, turn off “Ask where to save each file”, then paste your prompts and press Start.

While it runs, Chrome shows “started debugging this browser”. That's how the extension clicks and types for you inside your own tab.

Responsible use. AutoFlow only does what you could do by hand in your own Flow account. Your videos keep Google's watermarks and SynthID, and Google Flow's terms and usage limits still apply.
