The List of ChatGPT Plugins is a comprehensive directory of the third party and first party plugins that operated inside OpenAI's ChatGPT product between March 2023 and April 2024. The plugin system allowed GPT-4 to call out to external services, retrieve fresh information from the live internet, run code in a sandboxed Python environment, search private documents, and trigger actions in third party applications such as travel booking, grocery delivery, productivity automation, and computational engines. At its peak the Plugin Store hosted more than 1,000 published plugins from independent developers and well known consumer brands. OpenAI officially deprecated the entire plugin platform on April 9, 2024 and migrated its developer ecosystem to a successor product called Custom GPTs, which use a similar concept under the new name GPT Actions to call external APIs.
This article preserves the original aiwiki entries for individually documented plugins, supplements them with the launch partners and most cited community plugins, and provides categorical breakdowns drawn from the ChatGPT Plugin Categories index. Because the live store is no longer reachable, every entry below should be read as a historical record of a plugin that existed during the active beta and release period.
ChatGPT Plugins were announced by OpenAI on March 23, 2023, only four months after ChatGPT itself debuted in November 2022. The launch post described plugins as "eyes and ears for language models," because for the first time the model could pull live data from outside its own training set. The feature initially shipped to a small alpha cohort of ChatGPT Plus subscribers and developers from a waitlist.
OpenAI seeded the alpha with a curated group of eleven third party launch partners alongside two first party plugins of its own. The eleven launch partners were Expedia, FiscalNote, Instacart, KAYAK, Klarna, Milo, OpenTable, Shopify, Slack, Speak, and Wolfram, with Zapier added in the same announcement window. The two first party plugins were a Browsing plugin (which used the Bing search index) and a Code Interpreter sandbox (later relaunched as Advanced Data Analysis). OpenAI also published an open source Retrieval Plugin so any developer could host their own private vector database and let ChatGPT query it. The original ChatGPT Retrieval Plugin repository remains on GitHub as a reference implementation.
In May 2023 OpenAI rolled out the plugin store to all ChatGPT Plus subscribers as a Beta feature. Users could toggle plugins on under Settings, then browse a marketplace style interface to enable up to three plugins per chat. By the end of May 2023 the store carried more than 70 plugins from third party developers, and within months that number passed 1,000.
On November 6, 2023 at the OpenAI DevDay keynote, Sam Altman introduced GPTs, a more flexible system where each "GPT" was a custom configured version of ChatGPT that could include instructions, knowledge files, and external API actions. The GPT Store opened in January 2024.
On March 19, 2024 OpenAI disabled the ability to start new conversations with any plugin, locking the plugin platform to legacy chats only. On April 9, 2024 the platform was fully deprecated and existing plugin conversations stopped working. OpenAI directed all plugin developers to port their integrations into GPT Actions, which use the same OpenAPI specification format that plugins used. Several large partners published their own deprecation notices on the same day. For example, Zapier sunset its ChatGPT plugin and migrated users to a Zapier custom GPT.
A ChatGPT plugin was defined by an ai-plugin.json manifest file hosted at a fixed /.well-known/ai-plugin.json path on the developer's domain. The manifest pointed to an OpenAPI specification that described the plugin's HTTP endpoints in machine readable form. When a user enabled a plugin, ChatGPT downloaded the manifest, ingested the OpenAPI schema, and exposed each endpoint to GPT-4 as a callable function. During a chat the model decided when to call the plugin, generated a JSON request body that matched the schema, sent the call, and incorporated the response into its reply.
This design predated the modern function calling and tool use APIs and influenced their later shape. The same OpenAPI based pattern was reused for Custom GPT Actions and was a direct ancestor of the Model Context Protocol that Anthropic released in 2024.
The three plugin types were:
| Plugin type | Provider | Function |
|---|---|---|
| Browsing | OpenAI (first party) | Live web search and page reading via Bing. |
| Code Interpreter | OpenAI (first party) | Sandboxed Python with file upload, later renamed Advanced Data Analysis. |
| Retrieval | OpenAI (open source) | Self hosted vector store for private documents. |
| Third party | External developers | Any service exposing an OpenAPI compliant endpoint. |
The following alphabetical table consolidates plugins documented on aiwiki and the most widely cited launch partner and community plugins from the active 2023 to 2024 era. Categories follow the ChatGPT Plugin Categories taxonomy. All availability is listed as "Deprecated" because the platform shut down on April 9, 2024.

OpenAI launched the plugin program with three of its own tools so that users would have something to try even before third parties shipped. These first party tools were also the most heavily used plugins for the entire life of the platform.
The Browsing plugin gave ChatGPT live access to the internet through Bing search results. The model would issue a query, read a results page, click through to a candidate page, and synthesize an answer with citations. Browsing was paused for a period in 2023 after researchers showed it could be tricked into bypassing paywalls, then reintroduced as the Browse with Bing feature with safety improvements. After plugins were deprecated, browsing was rolled into ChatGPT as a built in tool available to every Plus and Enterprise user.
The Code Interpreter plugin opened a sandboxed Python environment where the model could write and execute code, accept file uploads, and produce charts or processed files for download. Power users adopted it for data analysis, spreadsheet wrangling, image processing, scientific computing, and quick prototyping. OpenAI relaunched it in August 2023 under the name Advanced Data Analysis, then merged it permanently into the default ChatGPT toolkit.
The ChatGPT Retrieval Plugin was published as an open source reference implementation on GitHub rather than as a hosted service. It allowed any developer to spin up a private vector database backed by Pinecone, Weaviate, Milvus, Qdrant, Redis, or several other stores, then connect it to ChatGPT so the model could answer questions grounded in private documents. The repository helped popularize retrieval augmented generation as a standard pattern for grounding language models on proprietary data.

The plugin platform launched a small but rapid developer ecosystem. Within weeks of the May 2023 public rollout, the Plugin Store carried more than 70 plugins, and within months that count crossed 1,000. The relatively low barrier of writing an OpenAPI spec and hosting a manifest meant that solo developers and small teams could ship a plugin in days rather than the months a mobile app store launch would require. Reviews of the time compared the moment to the launch of the iPhone App Store, although the comparison would prove premature when OpenAI pivoted away from the model less than a year later.
Key ecosystem patterns from the era included:
Despite the activity, OpenAI later observed that day to day usage of plugins clustered around a small set of utilities, mostly the first party tools and a handful of third party staples. Most ChatGPT Plus subscribers never installed a plugin, and even those who did rarely cycled through more than four or five favorites. This long tail problem was a major factor in the eventual transition to Custom GPTs, which presented one preconfigured tool per chat rather than a pile of toggles in a settings menu.
In announcing the April 9, 2024 shutdown, OpenAI gave several overlapping reasons for retiring the plugin platform:
Custom GPTs were introduced at OpenAI DevDay on November 6, 2023 and rolled out to ChatGPT Plus and Enterprise customers in the weeks that followed. The GPT Store opened publicly in January 2024 with a similar catalog model to the old Plugin Store, but with each entry representing a fully configured assistant rather than a single API.
GPT Actions replaced the third party plugin mechanism. They use the same OpenAPI specification format that plugins used, so most plugin developers could port their integration with minimal changes. The differences were operational rather than architectural: an Action belongs to a specific GPT rather than to ChatGPT as a whole, the GPT author writes the prompt that decides when to call it, and the user does not have to enable it manually.
Many of the original launch partners shipped Custom GPTs that mirrored their old plugins, including Zapier, Expedia, KAYAK, Klarna, Wolfram, and OpenTable. The Wolfram GPT, for instance, plays the same role as the Wolfram plugin and uses the identical computational backend.
