Google's Connected Apps Platform: Build Once, Live Inside Search and Gemini

Google announced something today that should be on every app developer's radar — and, in the usual Google fashion, it's wrapped in just enough vagueness that you need to read it twice.

The Connected Apps Platform is now in developer preview. The idea: you build your app once, and it can surface inside Google Search and the Gemini app — you choose Search, Gemini, or both. Instead of users leaving the AI conversation to open your app, your app shows up inside the conversation, at the moment they actually need it.

What it actually is

This is a unified platform for building and managing apps across Google's two biggest AI surfaces. The user-facing examples Google gives are concrete: designing a flyer in Canva, putting together a YouTube Music playlist, ordering groceries — all without leaving Search or Gemini.

The part I find most interesting as a developer: it's not a walled garden listing. You integrate, you submit, and you get an operations view afterwards. That's a channel, not a directory entry.

How you integrate

Two routes:

• A cloud-hosted MCP server — expose your app's capabilities through the Model Context Protocol, hosted in your own cloud.
• Android MCP via AppFunctions APIs — the on-device route for Android apps.

Then you register, test, and submit through the Google Connected Console. After launch, the console shows you traffic, latency, and error rates for your app inside Google's surfaces.

That last bit matters more than it looks. A listing you can't measure is a lottery ticket. Traffic, latency, and error rates in one place means you can treat this like any other channel: measure it, compare it against your other acquisition, keep it only if it earns its place.

There's also a brand detail worth noting: developers keep their verified brand identity and authenticated accounts. Your app shows up as yours, not dissolved into a generic Google answer. For anyone who's spent years building a brand, that's a meaningful choice — and one worth verifying in practice once you're inside the preview.

Who can get in right now

Here's the honest part, and it's the part most coverage will bury:

This is a US developer preview, rolling out in phases over the coming months via a waitlist. Google has given no date for broader availability. It has not stated pricing, fees, ranking rules, or data terms. If you read coverage quoting any of those, it's guessing.

There is real activity already, though. More than 50 Connected Apps are already live in Gemini, and Google named the next wave: Adobe, Experian, Localiza, and Peloton are coming to Search in the coming weeks, and Calm is launching on both Gemini and Search. That tells you something about who Google is prioritising first — productivity, finance, travel, fitness, wellness.

What's actually new here

Let me be straight about this, because the headlines won't be: Connected Apps themselves are not brand-new. Consumer integrations already existed in AI Mode earlier in 2026. Users have been reaching apps from inside Google's AI answers for months.

What changed today is the open developer platform: a public preview, a documented integration path, a console, and a waitlist any developer can join — instead of a set of hand-picked partnerships. The question shifts from "does the concept work" to "does the open platform send meaningful traffic, on fair terms, to developers who aren't Adobe or Peloton?"

Why I think this matters

Distribution is the hardest problem most apps have. Getting users to install something new is expensive and getting more so. Appearing inside Search and Gemini, at the moment a user expresses intent, is distribution you can't buy through an app store listing. If this works as described, it's a new acquisition channel — and early channels reward early movers.

MCP is becoming the shared language of AI integrations. A cloud-hosted MCP server isn't a Google-only investment. The same protocol thinking applies across the AI ecosystem, so building the MCP route now is work that transfers even if this particular platform disappoints.

The catches, stated plainly

• Google reviews everything. Submission is not a guarantee of acceptance, and the review criteria are Google's to set. This is distribution inside Google's products, on Google's terms.
• Commercial impact is unproven. No public numbers show what a Connected App listing is worth in users or revenue. The 50+ live apps prove the plumbing works, not the economics.
• Access is phased and US-first. Joining the waitlist is not joining the platform. International developers will wait an unknown amount of time.
• The terms are unstated. Pricing, fees, ranking, data terms — none of it has been announced. Any business case built today rests on assumptions Google hasn't confirmed.

What I'd do now

1. Join the waitlist if your app fits a Search or Gemini moment. Phased rollouts reward being early in the queue.
2. Map your app's MCP surface. Which tasks, in what order, with what inputs, would a user want inside a conversation? That mapping is the real integration work.
3. Watch the named partners. How Adobe, Experian, Localiza, Peloton, and Calm appear in Search and Gemini will show you what "good" looks like on this platform before you build.
4. Don't rebuild around it yet. Until you're in the preview and can see real traffic numbers, treat this as a channel to test — not a strategy to bet the company on.

What we don't know yet

• Broader availability date — only "phases over the coming months" for the US preview.
• Pricing and fees — not stated. Don't assume free, don't assume a revenue share.
• Ranking and surfacing rules — how Google picks which app appears for which query hasn't been explained.
• Data terms — what user data flows to your app, and under what terms, hasn't been stated.
• Real performance — traffic, conversion, retention are Google's claims so far, not independently verified results.

The door is open. Whether it leads anywhere profitable is something only the developers who walk through it will find out.
