About

AutoFlow — AI Script-to-Image Automation for Google Flow

AutoFlow is a side panel extension for Google Flow (labs.google) that converts a written script into cinematic image prompts and automatically generates and downloads all images — without manual copy-pasting.

HOW IT WORKS

1. Paste your script into AutoFlow.
2. AI (powered by Inworld AI / Mistral) splits it into scenes based on your target duration per scene.
3. Each scene is converted into a styled image prompt matching your chosen visual style (Cinematic, Oil Paint, Ghibli, Watercolor, Digital Art, Film Noir, Fantasy, Cyberpunk, Vintage, or Minimal).
4. AutoFlow submits each prompt to Google Flow automatically, waits for generation to complete, and downloads all output images directly to your computer — named by scene number and prompt content.

KEY FEATURES

• Script-to-scenes AI — paste any script and AutoFlow calculates how many scenes it contains based on your target duration, then generates one cinematic prompt per scene in parallel (up to 10 simultaneous AI requests).
• 10 visual styles — choose from Cinematic, Oil Paint, Ghibli, Watercolor, Digital Art, Film Noir, Fantasy, Cyberpunk, Vintage, or Minimal. Each style adds expert prompt modifiers automatically.
• Batch generation with configurable concurrency — choose 1–5 prompts per batch. Each batch is submitted one prompt at a time (1 second apart), then AutoFlow waits for all images in the batch to finish generating before sending the next batch.
• Smart tile-based download — AutoFlow tracks each generation by its unique tile ID in the Flow interface, ensuring every image is downloaded exactly once with no duplicates or missed files.
• Retry logic — each image gets up to 3 download attempts automatically if the first attempt fails.
• Named downloads — files are saved as scene-001_img01_prompt_text.png, making it easy to match images to script scenes.
• Manual prompt mode — enter any list of prompts manually (one per line) and batch-generate without a script.
• Pause / Resume / Stop controls — full control over generation at any time.
• Console log — live generation and download log visible in the side panel.
• Configurable download folder — images are saved into a named subfolder inside your Downloads folder.

WHO IS IT FOR

AutoFlow is built for content creators, filmmakers, video producers, social media teams, educators, and anyone who uses Google Flow to generate images at scale. Instead of manually typing each prompt and clicking download for every image, AutoFlow handles the entire workflow automatically.

PRIVACY & DATA

AutoFlow does not collect, store, or transmit any personal data. Your scripts and prompts are processed locally and sent only to the Inworld AI API for prompt generation (no identifying information is included). Images are downloaded directly from Google's servers to your own computer. The extension requires a one-time account registration (name only) stored in Appwrite to manage access tiers.

PERMISSIONS USED

• activeTab — to interact with the Google Flow tab you have open.
• scripting — to inject the automation script into the Flow page.
• downloads — to save generated images to your computer.
• storage — to remember your settings and prompts between sessions.
• debugger — to dispatch reliable mouse click events on the Flow interface (required for submit button interaction).
• sidePanel — to display the AutoFlow panel alongside the Flow page.
• tabs — to detect which tab is the active Flow project.

AutoFlow only operates on labs.google/fx/tools/flow pages. It does not access any other websites or browser tabs.
