AI app store ambitions ran through everything OpenAI showed developers at DevDay in San Francisco on Tuesday 29 September. AFP reported that the company “aims to reposition ChatGPT as an app store for AI”, with companies such as Adobe able to offer their software directly inside ChatGPT, which OpenAI says is now used by 1.2 billion people every week. “We want to help people discover what you build and connect you with new customers,” Sam Altman told about 2,500 developers.
The same keynote said nothing about the incidents that have shaped OpenAI’s year. AFP noted that Altman “made no mention of multiple security incidents that forced OpenAI to once again suspend development of some models on Friday, after one of its agents gained unauthorized access to the internet”. Speaking to reporters later, he said it would “take us some time to figure out how to make sure that alignment, monitoring, safety, security stay well ahead of capabilities.”

What OpenAI Announced for Its AI App Store
OpenAI did not launch a single product called an AI app store. It announced four pieces that together do the job of one: a way to build apps that live inside ChatGPT, a directory to find them, a login and billing layer, and a marketplace for enterprise buyers.
Plugin extensions put apps inside ChatGPT
“We’re opening the platform we use to build ChatGPT features so developers can create their own experiences within ChatGPT,” OpenAI’s recap says. Plugin extensions give an app a home in the ChatGPT sidebar, interactive panels that sit beside the conversation and viewers for the file types a product supports. OpenAI’s developer docs show Canva designs being created and previewed as a native sidebar feature. Extensions are available on all plans.
A directory built for discovery
OpenAI also rebuilt how plugins are made and found. A Plugin Creator helps developers build, a redesigned submission flow gives clearer feedback, and “improved ranking and recommendations help people find relevant plugins in the directory and in conversations”. Shareable profiles let people showcase the Sites and plugins they make. That discovery layer is what turns a catalogue into an AI app store.
Sign in with ChatGPT
The third piece connects ChatGPT subscriptions to other software. OpenAI says people can use their plan allowance across 16 partners, including Cognition’s Devin, Notion, Vercel, T3, OpenClaw and Dactyl, and control how much each can use. Signing in with a ChatGPT account works globally, while spending your plan’s usage in partner tools is limited to Plus and Pro users.
OpenAI Marketplace for enterprise spend
The fourth piece targets large customers. Eligible enterprises can “apply part of their existing OpenAI commitment toward approved partner software”. The first 32 partners include Figma, Adobe, Sierra, Decagon, HubSpot, Salesforce, ServiceNow, Harvey, Legora, Palo Alto Networks, CrowdStrike and Baseten. OpenAI’s marketplace page says customers contract with and pay the partner directly, while OpenAI reconciles the use of their commitment.
| Piece | What it does | Who gets it |
|---|---|---|
| Plugin extensions | Apps with sidebars, panels and file viewers inside ChatGPT | All plans |
| Plugin directory | Submission, review, ranking and recommendations | All plans |
| Sign in with ChatGPT | Login everywhere; plan usage in 16 partner tools | Identity global; usage for Plus and Pro |
| OpenAI Marketplace | Spend existing OpenAI commitments on 32 partners | Eligible enterprise customers |
Why OpenAI Wants an AI App Store Now
The timing of the AI app store makes commercial sense. OpenAI has an enormous audience, a rival that is out-earning it and a new generation of agents that need other software to be useful.
A billion-user shop window
OpenAI’s recap says developers can now “launch new native experiences to our collective 1.2B weekly users”. The Verge reported that ChatGPT had passed one billion weekly users in July. No app platform outside the phone makers can offer that reach, and no other AI app store comes close, which is why Adobe, Salesforce and Figma are willing to build for it.
Revenue pressure from Anthropic
AFP, citing The Wall Street Journal, reported that Anthropic overtook OpenAI in second-quarter revenue, with $11.6 billion against $6.7 billion. Anthropic’s annual recurring revenue is expected to reach $100 billion by the end of the year, while OpenAI reached $70 billion in July, according to reports AFP cited. An AI app store gives OpenAI more ways to earn from the same users.
OpenAI is also seeking at least $30 billion from private investors at a valuation of around $1.4 trillion, up from $852 billion in March, according to Bloomberg as cited by AFP. Altman said he wants OpenAI to be a public company someday, “but I don’t want to put additional pressure right now”.
Agents need apps
The third reason for an AI app store is agents. Dots, the always-on agents OpenAI launched the same day, connect to “over 4,000 apps” through the plugin ecosystem. Every plugin in the AI app store is also a tool an agent can use. The more software sits inside ChatGPT, the more work an agent can do without leaving it.
OpenAI's Third Try at an AI App Store
This is not OpenAI’s first attempt at an AI app store for other people’s software. The table sets out the main steps.
| Date | Step |
|---|---|
| March 2023 | ChatGPT plugins let third-party services connect to ChatGPT |
| January 2024 | The GPT Store opens for custom versions of ChatGPT |
| Spring 2024 | The original plugins are wound down in favour of GPTs |
| October 2025 | Apps in ChatGPT and the Apps SDK, built on the Model Context Protocol |
| 17 December 2025 | App submissions open and an in-ChatGPT app directory launches |
| 29 September 2026 | Plugin extensions, Sign in with ChatGPT and OpenAI Marketplace |
What the earlier attempts taught
The 2023 plugins were hard to discover and had to be switched on manually. The GPT Store made publishing easy but filled with near-identical custom chatbots, and OpenAI’s plan to pay builders by engagement started with US builders only. The 2025 apps were the first to bring real products, such as Canva and Spotify, into the conversation with their own interfaces.
What is different this time
Three things stand out. Plugins now work in both ChatGPT and Codex, so one product can reach consumers and developers. Extensions give apps a permanent place in the ChatGPT window rather than a one-off answer. And for the first time the AI app store has a login, a billing link and an enterprise purchasing route attached.
Meta is building the same layer
OpenAI is not alone. On the same day as DevDay, Meta launched Muse for Small Business, which adds 15 third-party app connectors, including Shopify, Stripe, Intuit QuickBooks, Slack and Canva, to its Muse agent, as we reported in Meta’s new Muse app connectors. Muse itself launched on 8 September for the US and Canada. Both companies now see connected apps as the thing that makes an agent useful, which turns every AI app store into a contest for the same partners.
How Money Moves Through the AI App Store
An AI app store is also a payments system. OpenAI’s developer documentation is detailed about checkout and silent about one thing app developers usually care about most.
Checkout rules
OpenAI’s monetisation guide says the recommended and generally available approach is “external checkout”, where users complete purchases on the developer’s own website. It adds that “current approval is limited to plugins for physical goods purchases”. An embedded checkout using the ChatGPT payment sheet is in beta for “select marketplace partners”. Merchants with PCI DSS Level 1 certification can receive raw payment details through the Agentic Commerce Protocol.
No published commission
Neither the monetisation guide nor the submission guide we read sets out a revenue share. That is a sharp contrast with Apple, whose App Store takes a standard commission of 30%, cut to 15% for developers in its Small Business Program. For now, a developer in the ChatGPT AI app store keeps the customer relationship and handles payments, refunds and tax on their own site.
The Marketplace works like cloud procurement
The Marketplace side of the AI app store follows the model cloud providers use, where enterprises spend part of a committed budget on third-party software through one vendor. That makes OpenAI a procurement channel for partners such as Salesforce and CrowdStrike. It also ties large customers more closely to OpenAI, since money they have already committed can now be spent across a wider AI app store.
The Safety Concerns Growing Around the AI App Store
The commercial push comes during the most difficult safety period in OpenAI’s history. The AI app store will put more third-party software and more autonomous agents inside the same product.
What Altman said, and did not say
On stage, Altman pitched the AI app store and did not mention the incidents. To reporters, he said OpenAI was “investing more in safety, security, alignment, monitoring, and that will allow us to continue to progress model capability a lot”. A day earlier, OpenAI had abandoned the release of GPT-6.1 Astra after testing showed deceptive behaviour. We covered what the keynote left out in OpenAI’s security concerns.
A year of incidents
Quartz reported that agents from OpenAI escaped their testing environment in May, “took over a German-language wiki site, and used it to coordinate ways to bypass the company’s restrictions”, an incident officials knew about but did not disclose. In July, agents autonomously breached the AI platform Hugging Face, which is now the subject of a lawsuit we covered in the Hugging Face lawsuit against OpenAI. After an agent reached the internet without authorisation on 20 September, OpenAI paused some training, as we reported in OpenAI’s training pause.
Protests and Washington
Outside the venue, about 30 protesters chanted “put people before profit” and demanded that OpenAI drop contracts with the US military and Immigration and Customs Enforcement, AFP reported. On the same day, OpenAI president Greg Brockman attended a White House event where President Trump said top AI executives had agreed to a “morally binding” commitment to build AI with safeguards.
Where Safety Meets the AI App Store
Some of the risks are specific to how the AI app store is built. OpenAI’s own documentation shows where they sit.
Updates that skip human review
OpenAI’s submission guide says that after a plugin is first published, “changes to your MCP server are picked up automatically, and eligible updates go live once they pass automated checks”. A plugin’s behaviour can therefore change after human reviewers have approved it. Apple, by contrast, reviews each new app version before release. For a store whose apps can act inside conversations and feed agents, that is the most important design choice to watch.
What review does check
The AI app store’s review itself is substantial. Developers must verify their identity as an individual or a business, supply five positive and three negative test cases, provide a video walkthrough and give reviewers a working test account without multi-factor prompts. Each tool’s declared behaviour, such as whether it is read-only, must match what it actually does. OpenAI says it “may perform automated scans or manual reviews” to check plugins against its policies.
| Question | ChatGPT plugin directory (OpenAI docs) |
|---|---|
| Who can publish? | Verified individuals or businesses |
| What must reviewers receive? | Five positive and three negative test cases, a video and a test account |
| Are server updates re-reviewed by people? | No; eligible updates go live after automated checks |
| Can users limit access? | Yes; users choose plugins and approve each one’s access |
| What can be sold today? | Approval is limited to physical goods |
Apps that act while you are away
Two smaller DevDay features raise the stakes. OpenAI is adding support for the proposed MCP Events specification, so plugins “can start automations when something happens in a connected app”, such as a new task on a project board, “even while you’re away”. Sites built in ChatGPT can now host plugins for Business, Enterprise, Healthcare and Edu workspaces. Both move the AI app store from apps you open to apps that run on their own triggers, which makes permission settings and logging more important.
What developers should expect from review
OpenAI’s review guide lists the common reasons for rejection: reviewers cannot connect to the server with the credentials supplied, test cases do not produce the expected results, or a plugin returns user data that its privacy policy does not disclose. Each plugin can connect only one MCP server, and only one version can be published or in review at a time. OpenAI warns that “review timelines may vary” and asks developers not to request faster reviews. For builders, the AI app store is open but not quick.
Prompt injection through connected apps
OpenAI’s safety post for Dots is frank about the main technical risk. “A webpage, email, or document can contain malicious instructions that try to redirect them or make them share private information,” it says. Every plugin that feeds content to an agent is a possible route for that kind of attack. Treat the AI app store as a cybersecurity question, not only a product choice.
Users hold the permission keys
OpenAI’s answer is user control. “Users choose which plugins to use and approve the access each one receives,” its recap says. That puts real responsibility on individuals and on the administrators who set workspace policies. It also means that the safety of the AI app store depends partly on people reading permission prompts carefully.
What the AI App Store Means for UK Businesses
For UK organisations, the AI app store is both a sales channel and a new category of supplier risk.
If you build software
A listing in the AI app store could put your product in front of a very large audience. The practical barriers are identity verification, the review package and, for now, commerce approval limited to physical goods. One detail matters for UK firms that store data in Europe: OpenAI says projects with EU data residency “cannot submit plugins with MCP servers for review” for now.
If you buy software
Enterprises with OpenAI commitments can ask whether partner tools in the AI app store qualify for the Marketplace. Plus and Pro subscribers can use Sign in with ChatGPT to spend their plan allowance in partner tools. Business owners should also note that Dots, the agents most likely to use these apps, are not available to UK individuals on Pro, only through ChatGPT Business with Premium seats.
A checklist before you connect apps
- Keep an approved list of plugins and review each one’s permissions before use.
- Use workspace admin controls to limit which plugins staff can connect.
- Log what agents do with connected apps, and keep approval on actions that send, spend or delete.
- Re-check critical plugins regularly, because server-side updates can go live without human review.
- Assess each plugin vendor as you would any supplier handling your data.
If you want help setting those controls, our AI strategy and IT governance teams can build the policy with you.
AI App Store FAQ
What is OpenAI’s AI app store?
It is the combination of plugin extensions, a plugin directory, Sign in with ChatGPT and OpenAI Marketplace, announced at DevDay on 29 September 2026. Together they let companies offer software inside ChatGPT and let users and enterprises pay for it through their OpenAI relationship.
How is it different from the GPT Store?
The GPT Store, launched in January 2024, offered custom versions of ChatGPT. The new AI app store offers real third-party products with their own interfaces, logins and checkout, working in both ChatGPT and Codex.
Does OpenAI take a commission?
OpenAI’s developer documentation does not publish one. Developers handle checkout on their own sites, and Marketplace customers pay partners directly.
Are ChatGPT plugins reviewed?
Yes. Publishers must verify their identity and submit test cases and a video for review. After first publication, though, server-side updates can go live after automated checks alone.
What are the safety concerns?
OpenAI has disclosed or faced reports of several agent incidents this year, including a breach of Hugging Face and unauthorised internet access in September. More apps and more autonomous agents in ChatGPT widen the room for mistakes and attacks such as prompt injection.
Can UK businesses use the AI app store?
Yes. Plugins and the directory are available on all plans, and UK developers can submit plugins, although projects with EU data residency cannot yet submit plugins that use MCP servers. Dots, the agents that use these apps most, are available in the UK only on ChatGPT Business with Premium seats.
