OpenAI launches ChatGPT sign-in for 16 partner tools
Fri, 2nd Oct 2026 (Today)
OpenAI has introduced "Sign in with ChatGPT" for external software tools, launching with 16 partners.
The new sign-in option lets ChatGPT Plus and Pro subscribers use their existing accounts and subscription allowances in participating third-party products without creating an API key.
Initial partners include Cognition, Notion, Lovable, Vercel, OpenClaw, T3 and Dactyl. Eligible usage in those tools will count toward a user's existing plan limits, and users will be able to decide how much of their allowance each tool can consume.
The move extends ChatGPT accounts beyond OpenAI's own products by linking identity and model access to a consumer subscription. It also gives software providers a way to offer access to OpenAI models through a familiar login instead of requiring separate developer setup.
Identity access through the sign-in system is available globally. The plan-based usage model is available to Plus and Pro subscribers in participating tools.
The launch points to a closer link between OpenAI's consumer subscription business and the broader ecosystem of software products built around its models. For users, the system reduces the number of passwords they need to manage and shortens the process of connecting tools and plugins that rely on OpenAI services.
For partner companies, the arrangement could reduce friction when onboarding customers who already pay for ChatGPT. Instead of asking users to open a developer account and generate an API key, participating tools can rely on an existing ChatGPT subscription for model access within agreed limits.
OpenAI described the system as a way for subscribers to "do more" with an existing ChatGPT plan across a wider range of applications. The initial partner list spans coding, productivity and developer tools, suggesting the programme is aimed at users who want to apply OpenAI models in day-to-day software workflows rather than only inside the ChatGPT interface.
Partner rollout
The named partners include a mix of start-ups and established software platforms. Cognition is known for Devin, its coding assistant, while Notion has added artificial intelligence features to its workplace software. Vercel serves developers building and deploying web applications, and other early participants include OpenClaw and Dactyl.
The inclusion of usage controls suggests OpenAI wants to give subscribers more oversight as model consumption spreads across multiple products. That may help users avoid unexpectedly exhausting plan limits when several connected tools draw on the same subscription allowance.
Broader strategy
The launch also reflects growing competition among artificial intelligence providers to make model access easier for end users who are not traditional developers. By embedding account-based access into partner software, OpenAI is trying to expand the practical use of paid ChatGPT subscriptions beyond its own website and apps.
Users can sign in to a range of tools with their ChatGPT account to connect plugins more quickly and manage fewer passwords.
