Google Flow Explained, and Whether Those "Product Ad Commands" Are Real

Lists of “Google Flow commands” for product videos circulate: /product reveal ad, /unboxing ad, /lifestyle ad, /macro detail ad, /360 product spin. Here is what Flow is, and whether those commands exist. Everything below comes from Google’s own pages, read in September 2026. AI tools change monthly, so check the app before relying on a detail.

What Flow is

Google launched Flow, an AI filmmaking tool, on 20 May 2025. Google called it “the evolution of VideoFX, a Google Labs experiment that launched last year”, and at launch it was for “subscribers of our Google AI Pro and Google AI Ultra plans in the U.S.” Its own title now reads “AI Creative Studio for Video, Images & Custom Tools”, and the help centre describes it as a way to “create cinematic clips, scenes, and stories with consistency”.

Models, now. Flow is “powered by various Veo models, in addition to Gemini Omni (available in standard 720p and draft 360p) and Gemini”. Its model page lists Veo 3.1 in Lite, Fast and Quality versions, Gemini Omni Flash 1.1, and Nano Banana models for images. At launch Google named Veo, Imagen and Gemini, with Veo 3 in the headline, so older guides describe a different tool.

Who can use it, and what it costs

• Age and place. You must be 18 or over and in a supported country. The list is long and includes the US, the UK, India and the Philippines. “VPNs will not enable access in unsupported regions.”
• Regional limits. “Editing of uploaded videos is currently not supported” in the European Economic Area, Switzerland and the UK, and extra AI credits cannot be bought in Japan (“AI credits are currently unavailable in Japan”, under “Purchase AI credits”).
• Subscription or not: Google’s pages disagree. The “Get started” page says to “be subscribed to Google AI Plus, Google AI Pro, or Google AI Ultra”. The credits page says: “With or without a subscription, you receive 50 Google Flow credits per day”, and that without one you may not be able to generate videos “during peak hours, roughly 2 PM to 5 PM UTC”. Flow’s own product page sides with the credits page: “Try Google Flow free of charge”, with a tier “Without a Google AI Subscription”. Two of the three pages say you can start free, so the “Get started” line looks out of date, but check the app.
• Credits. On top of the daily 50, “Google AI Pro subscribers receive an extra 1,000 Google Flow credits each month”, and “Google AI Ultra $200 subscribers receive an extra 25,000”. A short clip in the cheapest mode costs a handful of credits, and Google warns that “model costs are evolving fast”. Flow’s own page lists Google AI Plus at $4.99, Pro at $19.99 and Ultra at $99.99 or $199.99 a month, and adds that “Prices may vary by market”.
• Watermarks. Outputs “include invisible SynthID watermarks”, and “a visible watermark will be applied automatically if you reside in India, South Korea, or Vietnam.”

What Flow offers

• Frames to video: set a start frame, or a start and an end frame, to “create transitions, animate images, or generate a video that starts and ends with specific images”.
• Ingredients: reference images reused across clips, so you can “consistently use the same images for your character and key objects from one clip to the next”.
• @ references: “In the prompt box, type @ followed by your character’s name”, and the @ sign followed by “Voice” for a chosen voice. This is the only special prompt-box syntax Google documents for Flow’s video tools.
• Scenebuilder, to “arrange multiple clips in a sequence”, plus extend for Veo clips (“You can currently only extend Veo generated videos”).
• Flow Agent, a chat assistant for planning and generating; “by default, the Agent asks for your permission before taking any actions that use your AI credits.”
• Tools: you can “build custom, reusable tools and mini-apps using natural language”, share them by link, and “Google Flow also comes with a preset of Tools supplied by Google”.

Are the “product ad commands” real?

We read all 23 articles in Google’s Flow help centre (15 on Flow, 8 on the separate Flow Music), Flow’s own product page and the launch post, and searched them for slash commands and for each command’s words.

Myth that these are built-in Flow commands. Flow’s video help pages document no slash commands. On the keyboard-shortcuts page, ”/” is only the key that “opens the search” in the grid. The one slash feature in the help centre belongs to Flow Music, Google’s music app, where you can “set up custom slash commands” of your own; none is supplied for product videos. “Unboxing”, “lifestyle” and “macro” appear nowhere in the help centre, and “360” appears only as a video resolution (“Generate videos at lower cost with Omni 360p”), not a turntable shot.

True that they can be used as prompt ideas. Nothing in Flow’s video help pages gives a slash a special meaning in the prompt box, so “/unboxing ad” is read as a very short description, and Google asks for more: “Be specific about the subject, action, environment, lighting, and style.” Google’s own tip for product shots is practical: “For the best results, provide subject or product references on a plain or segmented background.”

Unverified whether any Tool inside the app carries names like these, but the six Tools that Flow’s own page lists as created by Google do not: Type Overlays, Video Resizer, Image Editor, Storyboard Studio, Shader Effects and Mockup. A Tool is also opened from the Tools panel, not typed into the prompt box, so even a Tool with such a name would not be a slash command.

Our reading

The commands are good recipes for product videos, written to look like built-in features. What makes Flow work is the real set of controls: a clear prompt, a clean product image as an ingredient, start and end frames for a spin or a reveal, and Scenebuilder to put the clips together.
