Replit's coding agent, the tool many people now use to build a small app or online business by describing it, can now run Google ad campaigns and buy supplies from inside the same chat. In both cases it prepares everything and then waits for the owner to approve the spend. Ads are open to Replit's Pro plan worldwide; buying is limited to the United States.
The agent that built the app can measure the ad
A common place for a small business to get stuck with online ads is the gap between clicks and customers. The owner can see how many people clicked, but not whether any of them signed up or bought. Without that, the second month of ads is a guess.
The agent closes that gap because it wrote the app. Tracking a sign-up means adding a few lines in the right place in the product, and the agent knows where that place is. It reads the website, drafts the headlines and images, and suggests a daily budget. The campaign can be created paused, and nothing runs until the owner approves it. Google then mixes the headlines and images into ads across Search, YouTube and its other channels.
Take a founder who built a booking app for dog groomers and sets $40 a day for 30 days. That is $1,200 at most. If a groomer is worth $300 a year, four new customers pay it back. The tracking is what tells the founder whether the month brought four or one, and that answer decides the next month's budget.
Google already has its own assistant, Ask Advisor, that can generate campaigns and creative inside Google's tools. What changes here is where the work happens: in the chat of the tool that made the product, which already knows what the product does and where a customer signs up.
Buying needs the owner, and that is on purpose
The buying side works the way a careful assistant would. Ask for 50 shipping boxes under $75 delivered, and the agent opens the store's website in its own browser, picks the options and fills the cart. Because it uses the ordinary website, it needs no deal with each shop. If the store wants a login, the owner takes over and hands back control.
Then it stops. The owner sees the merchant and the final total in the Link wallet, Stripe's payment app, and approves or declines there. The approval checks are enforced in code, not left to the AI model. If the price changes during checkout, the agent has to ask again.
The wallet itself is not new; Stripe launched Link for agents in April 2026. What is new is a small business owner having it inside the tool that already holds their product and their customers. For a one-person shop, the saving is less the 20 minutes of clicking and more the comparison: the agent can lay out three box suppliers with delivery costs side by side before the owner decides.
What follows when everyone can launch an ad in minutes
When AdWords went self-service, the difficulty moved from getting into the system to doing well in it. The same thing is likely to happen here. If a founder can launch a campaign in minutes, so can every competitor in the same niche, and many will end up with similar-sounding ads. The advantage then moves to what is behind the click: a clear page, a product that does what it says, and a founder who reads the sign-up numbers and changes something.
That is also why the approval step matters beyond safety. The owner who sets the budget, reads the results and decides to continue is the only part of the loop that cannot be copied by a competitor with the same agent. The founders who gain most will be the ones who treat the agent as a fast junior marketer, and check its numbers every week.
