OpenAI Codex adds plugins for non-developers

OpenAI brings plugins to Codex

On 2 June 2026, OpenAI announced a significant expansion of Codex. The product started as a coding assistant. It is now positioning itself as a workplace tool for analysts, marketers, operators, designers, and finance teams.

Six role-specific plugins launched today: data analytics, creative production, sales, product design, public equity investing, and investment banking. Each plugin bundles relevant apps, skills, and workflows. Together they cover 62 popular applications and 110 skills, all accessible without writing a line of code.

OpenAI also introduced Sites, a feature that lets teams create and share interactive web pages from inside Codex. And annotations now let users point at a specific part of a document, chart, or slide and ask Codex to refine just that section.

What is actually new here

Codex already had strong developer tools. The shift this week is explicit: non-developers now make up roughly 20% of weekly Codex users and are growing more than three times faster than the developer base.

The plugins signal OpenAI’s intention to compete for the broader knowledge worker market. A marketing team using the creative production plugin can take a brief and turn it into display ad variations via Figma, Canva, and other connected tools. A sales team can pull customer context from Salesforce and HubSpot to prepare for a meeting.

This is a meaningful move. But it is worth noting what it is not. These plugins live in Codex, not in ChatGPT. That distinction matters for how you evaluate the product.

Codex versus ChatGPT: the platform gap

Claude’s Cowork feature moved in the opposite direction this week. Claude extended its tools to work across the browser, desktop, and chat interfaces simultaneously. That means a UK business running Claude has one consistent experience wherever staff are working.

Codex remains a separate product from ChatGPT. A business on ChatGPT Business or Enterprise does not automatically get the Codex plugins. They are a distinct subscription and a distinct interface.

At gecco, we have seen this matter in practice. Several clients evaluated Codex alongside Claude Cowork in recent months. The single-billing model of Claude’s subscription was a consistent factor in their decision. ChatGPT usage through Codex is billed by consumption, which creates unpredictable costs at scale. That is not a reason to dismiss Codex. It is a reason to evaluate it carefully against your actual usage patterns.

A more focused OpenAI

The broader context here is positive. OpenAI has spent the last few months moving away from consumer novelty features and towards practical business tools. This Codex expansion, the deeper enterprise integrations, and the sharper focus on real problem-solving reflect a company finding its footing in the workplace market.

That is good for the sector. Competition between Anthropic, OpenAI, Google, and Microsoft produces better tools for UK businesses. Each platform is genuinely improving.

What has not changed is the 80/20 principle that governs successful AI adoption. The technology is moving fast. The harder work remains helping teams understand what these tools actually do, building the workflows that make them useful, and ensuring people have the confidence to use them every day.

What to watch

Sites is interesting. The ability to generate and host lightweight interactive web pages from inside an AI tool has practical applications for client reporting, project dashboards, and internal briefings. It is in preview for Business and Enterprise customers and worth keeping an eye on.

The open plugin ecosystem OpenAI is building toward is also significant. If partners can deploy their own plugins directly in Codex and ChatGPT, the range of connected workflows will grow quickly. That changes the evaluation question from what can this tool do today to how quickly can we build what we need.

Practical considerations for UK SMEs

• If your team is on ChatGPT Business or Enterprise, Codex is a separate product. Check whether the plugin you need requires an additional subscription before building a workflow around it.
• If you are evaluating AI platforms now, compare billing models directly. Consumption-based pricing can work well for low-frequency tasks and less well for high-volume daily use.
• The role-specific plugins reduce setup time. If your sales team has been reluctant to adopt AI tools, a Codex plugin pre-connected to Salesforce and HubSpot lowers the barrier significantly.
• Sites could replace some of your current reporting and dashboard tools. It is worth a short trial if your team produces regular client-facing materials.

Next step

Platform decisions like this one are easier when you know where your business sits with AI adoption. Take the AI readiness assessment to see where your team stands and which tools are most likely to deliver value for your specific workflows.
