Open Auto Flow on the Chrome Web Store and click Add to Chrome. Chrome keeps it updated automatically. Pin it from the puzzle-piece icon in the toolbar for quick access (optional).
Use this when the newest version is not on the Chrome Web Store yet (still in review). It takes about a minute and works in Chrome and Microsoft Edge.
Show the manual install steps
- Download and unzip. Download
auto-flow-extension_10.8.58.zip, right-click it and choose Extract All…. You get a folder that containsmanifest.json. - Open the Extensions page. Type
chrome://extensions/in the address bar (on Edge:edge://extensions/). - Turn on Developer mode with the switch in the top-right corner of the page.
- Load the extension. Click Load unpacked and select the unzipped folder (the one that contains
manifest.json, not the .zip file). - Done. The extension appears in the list. Pin it from the puzzle-piece icon (optional).
Updating a manual install: download and unzip the new .zip over the old folder, then go to chrome://extensions/ and click the circular Reload icon on the extension's card.
Keep in mind:
- Keep the unzipped folder where it is. Deleting or moving it removes the extension from the browser.
- Developer mode must stay on for an unpacked extension to keep running.
Auto Flow needs two sign-ins:
- Sign in with Google in the extension to load your plan. Nothing can start until the plan has loaded.
- Sign in to Google Flow (
flow.google.com) with your own Google account. The extension opens the Flow tab for you. Images and videos are generated by your Flow account (Gemini Pro / Ultra) and use its credits and quota.
Plans pay for the automation tool only. They do not mean unlimited generation. Plans never auto-renew; when one ends, the extension goes back to Basic and your data in the browser stays as it is.

- How to buy: inside the extension, click the plan badge in the top bar → Upgrade. Pay with PayPal, USDT/Binance, or VietQR bank transfer (Vietnamese banks only). The plan activates on the Google account you signed in with; press Refresh status after 1-3 minutes.
- 6 months cost the same as 5 months, a year the same as 10. Upgrading Plus → Max mid-term charges only the difference for the days left.
- One device at a time: signing in on another device signs the old session out.
- 4K video needs Lite or higher and a Google Flow Ultra account.
- Refunds: within 24 hours of payment, see the Refund Policy. Try the free Basic plan first.
- Click the Auto Flow icon in the toolbar (or the floating button on the Flow page). It opens its own control window.
- Sign in with Google in the extension so your plan loads. The badge in the top bar shows your current plan.
- Sign in to Google Flow in the
flow.google.comtab the extension opens. The top bar shows your Flow sign-in, remaining credits and token expiry. - Choose Flow Image or Flow Video, then the model, aspect ratio and number of images/videos per prompt.
- Paste your prompts or import a
.txtfile: one prompt per line, or separate multi-line prompts with a blank line. - Press Start. Results are saved to your Downloads folder, one subfolder per task. Click a result in the table to open the file.
Keep the Flow tab open while a batch runs. You can close the control window: the batch keeps going and your session comes back when you reopen it.
- Batch prompts - paste or import a
.txt; each prompt becomes a row. Run many rows at once with the number of threads you choose. - Flow Image and Flow Video in one queue - two generators sharing one queue, one image library and one character library.
- Reference images & library - attach up to 10 images per prompt. The library assigns images to rows by keyword or by exact name. Sequential mode uses the previous row's result as the next row's reference to keep characters and scenes consistent.
- Character library - save characters with an image, a personality and a voice (preset or custom, with preview), then call them with
@namein Flow Image and in Flow Video's Ingredients mode. - Randomized video duration - one fixed duration, fully random, by formula (videos per length), or by a tag in the prompt:
[4s],{6s},<8s>. - Upscaling & download resolutions - images at 1K / 2K / 4K, videos at 720p / 1080p / 4K. Only the resolutions you tick are downloaded.
- Gemini watermark removal - removes the Gemini mark from the corner of images in the browser before saving, on every plan.
- Multi-task queue - name tasks, edit their settings, pause / resume / stop / skip. Retry failed rows in one click, run only selected rows, filter by status. Temporary errors are retried automatically.
- Never lose your work - the engine runs inside the Flow tab. Prompts, queue, results and settings are saved continuously and restored when you reopen the panel.
- File naming & folders - save directly or one folder per task. Name files from presets (row number, prompt, timestamp, date, prefix) or your own pattern.
- Detailed log with plain-language explanations of Flow errors.
- 11 languages: English, Tiếng Việt, 中文, हिन्दी, Español, Português (BR), Русский, বাংলা, اردو, Türkçe, ไทย.
Batch image generation on Google Flow. Pick the model, aspect ratio and up to 4 images per prompt; seed and seed lock are included. Attach reference images per row or from the library, use @name for characters, and tick the download resolutions (1K / 2K / 4K).
Batch Veo video generation in three modes: Text → Video, Ingredients (video from reference images and characters) and Start / End frames. Start/end images can be distributed automatically: 1 start - N ends, N starts - 1 end, chain 1:2 → 2:3, or pairs 1:2 → 3:4. With the Omni Flash model, each row can also take a reference video (or one video for every row). Choose a fixed or randomized duration and the download resolutions (720p / 1080p / 4K).
Lists your tasks so you can rename them, change their settings, and pause, resume, stop or skip them. Basic holds 1 task, Lite and Plus 10, Max unlimited.

Auto Flow runs no AI models itself. It submits your prompts to Google Flow through your own signed-in session and never collects passwords. Prompts, images, videos, the queue and settings stay in your browser and go straight to Google Flow. The license server only receives your Google email, a sign-in token and a random install ID. See the Privacy Policy.
| What | Where |
|---|---|
| Images | Downloads/AutoFlow/Image by default, with a Task_<timestamp> subfolder per task (or saved directly, if you choose) |
| Videos | Downloads/AutoFlow/Veo by default, same per-task subfolders |
| Prompts, queue, results, settings, image and character library | The extension's local browser storage (chrome.storage.local) |
Removing the extension deletes its browser storage; files already in Downloads stay.
Nothing starts / "Sign in with Google to load data from the server" - sign in with Google in the extension, or press Refresh status so your plan limits load.
"Could not open a Google Flow tab" - open https://flow.google.com/ in the same browser, sign in to Google, then press Start again.
"You are not signed in to Google Flow" - sign in on the flow.google.com tab. The extension picks it up automatically.
"Flow tab not responding" - reload (F5) the flow.google.com tab and try again.
"Your licence is being used on another device" - one account runs on one device at a time. Sign in again to continue here.
4K is ticked but the run won't start - 4K needs a Google Flow Ultra account. Untick 4K or sign in to Flow with an Ultra account.
Flow returns 403 / "requesting too fast" - a temporary rate limit from Flow. Lower the thread count, wait a few minutes (or change IP with a VPN/proxy) and retry.
"Daily image/video quota exhausted" - your Flow account's quota for the day is used up. This comes from your Google plan, not from Auto Flow.
A mode is locked and the plan table opens - that feature is not in your current plan. Upgrade from the plan badge in the top bar.
The manually installed extension disappeared or stopped - the unzipped folder was moved or deleted, or Developer mode was turned off. Restore the folder, turn Developer mode back on and reload the extension.
