Mark Flow settings: what each option does
Open the Settings window, understand every page and option in plain words, know which ones to leave at their defaults and save your changes correctly.
Open Settings and save changes
Open the Mark Flow side panel (the panel on the right edge of the browser; press
Alt+Sto open it).Click the gear icon in the top-right corner of the side panel. In the small menu that opens, click Settings.
The gear menu in the top-right corner of the side panel. The Settings window opens on its own. The left menu lists the pages General, Account & plan, Downloads & logo removal, Providers, Mark Bridge & Flow API, AI Agent (MCP), Storage & data and About. Click a page name to open it.
Most options only take effect after you save. When you change something, Unsaved changes and a Save changes button appear in the top-right corner of the page. One click saves every change on every page, and a Saved notice appears. Options in a card labelled Applies instantly (theme, language) take effect as soon as you change them.
If you close the window with unsaved changes, Chrome asks whether you want to leave. Choose to stay and click Save changes if you want to keep them.
Options with a crown icon or an Upgrade label need a paid plan. When you are signed in, your settings are synced to your account so you can use them on another computer.

| Language | Tiếng Việt or English for all of Mark Flow. Applies instantly. | Your choice |

| Play a sound | Plays a sound with the notification. | Your choice (off by default) |
The Advanced card (labelled For experienced users) changes how Mark Flow works on the web pages. Beginners should keep the defaults.
| Option | What it does | For beginners |
|---|---|---|
| Wait for input box | The longest time (in milliseconds) Mark Flow waits for the prompt box on the web page to be ready. Default 1200 ms, that is 1.2 seconds. | Keep the default; raise it only on a slow computer or connection |
| Random pause between prompts | A random pause between two prompts, from the lower to the higher number (seconds). Default 3 → 10 seconds, so sending looks like a real user. | Keep the default |

Providers
A “provider” is a place that generates images and videos: Google Flow, ChatGPT, Gemini, Grok. This page sets the pre-selected values for each one. Beginners can keep the defaults and change things directly in the Gen tab when needed.
| Provider | Options |
|---|---|
| Google Flow | Default type (Image or Video), Image model, Image ratio, Video model, Video ratio, Video length; Flow voices with a Resync button. |
| ChatGPT | Model, Ratio, Fallback prefix, Close the tab when done, Delete the chat after generating. |
| Gemini | Model, Video ratio, Close the tab when done, Delete the chat after generating. |
| Grok | An Image / Video selector at the top of the card; Ratio; for images: Image quality (Fast or Best); for videos: Video length (6s, 10s) and Resolution (480p, 720p); Close the tab when done. |
- Ratio (aspect ratio) is the shape of the picture, for example 16:9 landscape, 9:16 portrait, 1:1 square.
- Fallback prefix: when Mark Flow cannot turn on ChatGPT's image mode, it adds this sentence in front of the prompt so ChatGPT knows to draw an image. Default
Generate an image of:. - Close the tab when done closes the provider's tab when the run ends. Delete the chat after generating deletes the conversation it just used, to keep your chat history tidy.
- Resync (Flow voices) reloads the list of voices from Google Flow for videos with a voice. It needs an open, signed-in Flow tab.
If you see The model list changed and your previous choice is gone. Pick again and save., pick a model again and click Save changes. How to use ChatGPT, Gemini and Grok: see ChatGPT, Gemini, Grok and Muse.
Mark Bridge & Flow API, AI Agent (MCP)

AI Agent (MCP) creates tokens so AI apps such as Claude Desktop or Codex can drive Mark Flow, and lets you choose whether the agent's results are saved to your computer. Requires the Pro plan. Full guide: Control Mark Flow with an AI agent.
Storage & data
This page shows how much space Mark Flow uses on your computer and helps you clean up.
- In use: the total size, split between Chrome storage and IndexedDB (the two places Chrome keeps extension data). Click Rescan in the top-right corner to measure again.
- Clean up extras: removes thumbnails stored inside tasks and old caches. If the history kept on this computer has more than 50 entries, only the 50 newest are kept. Settings, prompts and workflows are not touched.
