Key Takeaway: The ChatGPT App Directory gives UK companies a central marketplace to discover and deploy integrations, accelerating productisation in conversational UI.
Why it matters: The SDK turns chatbots into platforms, enabling developers to create interactive experiences that drive retention, upsell and measurable ROI.
OpenAI’s App Directory turns ChatGPT into a platform
The Verge published a detailed report on OpenAI's new App Directory and SDK, describing how developers can surface tools directly inside the ChatGPT UI. The Verge story outlining the App Directory and SDK explains the changes and early examples.

For product teams this is more than another feature release; it is a distribution channel. ChatGPT now hosts discoverable apps, each running interactive workflows inside conversations. That shifts the battleground from standalone apps to in-chat experiences where retention can compound.
Sam Altman, OpenAI CEO, framed the launch as a developer-first play.
"We are planning for a future where AI is augmented by specialised tools built by developers across the web," said Sam Altman, CEO of OpenAI, in coverage of the launch.

The £ and compliance opportunity most are missing
Most commentary focuses on novelty, not the commercial upside. Firms that map core workflows to interactive ChatGPT plugins can convert trial users into paying customers with lower acquisition costs.
In the UK, ChatGPT creates a platform where integration-first businesses can capture service fees, subscription revenue, and transactional margins. In the UK, ChatGPT unlocks packaged automation that previously required bespoke engineering or expensive vendor licences.
Adoption data and regulation shape the route to market. The UK regulator for data protection, the ICO, expects firms to assess AI impacts and data flows before deployment; adherence protects both customers and reputations. ICO guidance on AI and data protection outlines privacy checks firms must run.

Your 5-step roadmap to productise interactive experiences
- Audit current workflows and map 90-day goals to ChatGPT interactive experiences (measure trial-to-paid conversion).
- Prototype an SDK integration and track engagement metrics within 30 days (aim for 20% active-user lift).
- Run a GDPR-aligned data flow review and log vendor controls (complete before public rollout).
- Price a beta offering and test monetisation for 60 days (track ARPU uplift from App Directory installs).
- Scale distribution via the Directory and A/B test feature bundles over a 90-day cycle (target 15% retention gain).
How Anjin’s AI agents for developers delivers measurable results
Anjin's AI agents for developers turn prototypes into production agents designed for conversational marketplaces like the ChatGPT App Directory. The agent templates speed integration and ensure consistent telemetry across experiences.
Consider a mini case: a UK fintech embeds a payments assistant that onboards customers inside chat. Using the developer agent reduces integration time from eight weeks to two, and projected uplift shows a 30% faster time-to-revenue and a 25% reduction in support tickets.
Expert Insight: "Packaging domain logic as agents shortens the path from idea to paying customer, especially inside ecosystems such as ChatGPT's directory," says Angus Gow, Co-founder of Anjin.
To put it in practice, teams can start with the developer agent, link billing events, and test paid journeys in the App Directory. See developer pricing and packages on the Anjin pricing page for clear tiered outcomes. Anjin pricing plans for rapid agent deployment
