The Flow agent and Flow Tools are Google Flow's way past one prompt at a time. The agent takes multi-step requests: several variations of a clip, batch edits, sorting assets into collections and renaming them. Its queries cost no credits, but every Google AI plan carries a daily query limit that Google does not publish per plan, and any media the agent generates spends Flow credits. Google-made Tools such as Type Overlays, Video Resizer and Storyboard Studio are open to everyone; building or remixing your own Tool needs Google AI Plus or higher. **Both work on the web only.** Scenebuilder then stitches the clips together.


**30 credits** — One 10-second 720p Omni Flash 1.2 clip generated through the agent, by our arithmetic (November 2026).



- **0 credits** — Per agent query, within a daily limit per plan
- **Google AI Plus** — Lowest plan that can build or remix Flow Tools
- **Web only** — Agent and Tools are not in the Flow mobile apps


## Before you start: browser, project and plan

Open Flow on a computer. Flow Help says the agent and Tools run on the web and PC only, and Google recommends a Chromium browser; the Android and iPhone apps are for creating on the go, not for this workflow. Next, open the project you want to work in before you ask for anything. Everything the agent or a Tool generates is saved automatically to the open project, so starting in the wrong one means sorting files later. Google announced the agent for all Flow users in May 2026, and it is available globally wherever Flow itself is.

Your plan decides two things here: how many agent queries you get a day, and whether you can build Tools. The rest is the same for everyone. Every account, paid or not, gets 50 Flow credits a day, and paid plans add a monthly allowance on top. Whatever the agent or a Tool generates draws on that same pool, at the same per-clip cost as a prompt you type yourself.

| What you want to do | No subscription | Google AI Plus, Pro or Ultra |
|---|---|---|
| Ask the agent for multi-step tasks | Yes, within a daily query limit | Yes, with higher access (highest on Ultra) |
| Use Google-made Tools | Yes | Yes |
| Build or remix your own Tools | No | Yes, within a daily quota |
| Arrange clips in Scenebuilder | Yes | Yes |
| Media from the agent or a Tool spends Flow credits | Yes | Yes |

## Handing the agent a multi-step job

Until Google added the agent, Flow could run only one prompt at a time [1]. Google describes the agent as a creative partner built with Gemini that understands your project. In practice that covers four kinds of work. It can produce several variations of a video from a single request. It can apply one edit across a batch of clips. It can organize assets into collections and rename them. For images, Flow Help says it routes your request to whichever image model fits your inputs, so you do not pick between the Nano Banana models yourself.

The useful habit is to write the request the way you would brief an assistant. Say which clips you mean, how many variations you want, and what should change between them: camera angle, lighting, a line of dialogue. Ask for the collection names you will actually search for later. **One clear request beats five vague ones.** Vague requests still produce generations, and every generation counts against your credits, so precision is the cheapest setting you have.


> 💡 **Plan with the agent at peak hours:** Without a plan, Flow may block video generation roughly 2 PM to 5 PM UTC, but the agent and images still work, so use that window to organize and brief.


## What the agent spends, and the confirm switch

Talking to the agent is free. Flow Help says agent queries do not currently cost Flow credits; instead, each Google AI plan has a daily limit on queries, higher on the higher Ultra plans [2]. Google does not publish the number for any plan. Flow's own plan list only says Plus brings higher access to the agent and Ultra the highest. Free accounts get a useful bonus: during peak hours, roughly 2 PM to 5 PM UTC, video generation may be unavailable without a plan, but images and the agent still work.

Media is a different story. Credits are charged per generation, not per request, and one request can create several generations. Ask for five variations and you pay for five clips. As of November 2026, Flow's video models are Omni Flash 1.2 and Veo 3.1 Lite. One 10-second Omni Flash 1.2 clip at 720p costs 30 credits by our arithmetic; a Veo 3.1 Lite clip costs 10 credits, or 5 on Ultra. The free 50 credits a day cover about 16 seconds of 720p Omni video, or five Veo 3.1 Lite clips. Google retires Veo 3.1 Fast, Veo 3.1 Quality and Omni Flash 1.1 in Flow on December 5, 2026.

By default, the agent asks your permission before any action that uses credits. You can switch that to never confirm. Leave it on until you know what your typical request costs. The latest credit costs also show in the prompt-box settings, so check there before a large batch. Failed or safety-blocked generations return their credits within an hour. Unused credits never roll over, daily or monthly, as our [Google Flow credits guide](/articles/google-flow-credits) explains.


> ⚠ **Never confirm drains credits fast:** The agent asks before spending Flow credits by default; switching it to never confirm lets a request for several variations charge every generation without a pause.


## Google's ready-made Tools, and when to reach for each

Flow ships with a preset of Tools supplied by Google, and anyone can use them, with or without a plan. Flow's site lists Type Overlays for animated text, Video Resizer for converting a video into any aspect ratio, Image Editor, Storyboard Studio, Shader Effects and Mockup, among others. Storyboard Studio is the one to open first on a new piece: Google describes it as a place to write a script, create the cast and visualize a storyboard before you spend anything on video. Type Overlays and Video Resizer belong at the other end, once the clips exist. A sensible order for a short promo looks like this:

1. Draft the script and cast in Storyboard Studio.
2. Generate the clips, directly or through the agent.
3. Add titles or captions with Type Overlays.
4. Assemble the cut in Scenebuilder, covered below.
5. Run Video Resizer when one master needs a second aspect ratio.

Tools are not free in disguise. Media a Tool generates spends Flow credits like any other generation, and Flow always shows a warning banner when running a Tool might use credits. Whatever a Tool produces is saved to the open project. **Read the banner every time.** It is the only cost signal a Tool gives you before it runs.

## Building or remixing your own Tool

Custom Tools are where the plan matters. Flow Help says building them needs Google AI Plus, Pro or Ultra; without a subscription you can only use the pre-built ones [3]. The cheapest way in is Google AI Plus at $4.99 a month, which also adds 200 Flow credits a month. Google AI Pro at $19.99 a month adds 1,000. You describe the Tool in plain language, and Google's plans page calls the result vibe-coded. You can also remix an existing Tool instead of starting from nothing. There is a daily quota on Tools created, and Google does not publish its size.

Sharing needs care. A shared Tool link carries only the version that existed when you created the link; later edits need a fresh link. Anyone holding the link can see the Tool's code, name and thumbnail. Treat that code as public. Keep client names, private instructions and anything sensitive out of a Tool you plan to share. Avatar data cannot travel through Tools or public project links at all, for safety and policy reasons. If you later delete your Tool data in Flow's settings, Flow Help warns the deletion cannot be undone.


> 💡 **Strip secrets from shared Tools:** Anyone with a shared Tool link can see its code, name and thumbnail, so keep client details and private instructions out of any Tool you share.


## Finishing the cut in Scenebuilder

Each generation is short. Omni Flash 1.2 clips run up to 10 seconds without a plan and up to 15 seconds on a paid plan; Veo 3.1 Lite stops at 8 seconds. Anything longer is built from pieces. Veo Extend was retired on November 5, 2026, so extending a clip now needs a paid plan and Omni Flash 1.2, in steps of 3 to 10 seconds, on the web. Scenebuilder, open to every user, is where those pieces become one video.

Inside Scenebuilder you arrange clips in a sequence, change their order, trim the start and end of each with the handles, and preview and download the whole scene [4]. One gap matters for publishing. Flow's direct YouTube upload works only for single clips, so a full Scenebuilder sequence has to be downloaded first and uploaded through YouTube Studio. For the basics of projects, prompts and downloads that sit underneath all of this, see [how to use Google Flow](/articles/how-to-use-google-flow).


## FAQ

**Do family members share the agent limit and Flow credits?**

Yes. Flow usage limits and AI credits are shared by the whole Google One family group, not counted per member, and only the plan manager can buy credits or change the plan.

**Is media from the agent or a Tool watermarked?**

Every Flow output carries an invisible SynthID watermark. A visible watermark is an optional setting, applied automatically in India, South Korea and Vietnam unless you are on Google AI Ultra 20x.

**Can I buy more credits if the agent uses mine up?**

Only on Google AI Pro or Ultra, through Google One; Google AI Plus cannot buy AI credits, and purchases are unavailable in Japan. Google does not publish pack prices; they show at checkout.

**Can I delete what the agent and Tools have stored?**

Yes. Flow lets you delete projects one by one or all at once, and delete your Tool and Agent data; deleting Tool data cannot be undone.


## The bottom line

The agent is worth using from day one, because asking costs nothing and it turns a string of single prompts into one brief. Watch what it generates, not what it says: every clip it produces draws on the same credits as a manual prompt, so keep the confirmation on. Google's Tools cover titles, resizing and storyboarding for everyone. Building your own is a paid feature from Google AI Plus, and a shared Tool link exposes its code. Both stay on the web, and Scenebuilder finishes the job.
