See also: ChatGPT Plugins, ChatGPT Plugin Categories and Search Engine
Search engine ChatGPT plugins were a class of third party and first party extensions for ChatGPT that gave the chatbot the ability to query the open web, fetch the contents of a specific URL, and return cited results inside a chat session. They formed one of the most heavily used groupings inside the broader ChatGPT Plugins ecosystem during its short lifespan from March 2023 to April 2024. The category overlapped with the Web Development ChatGPT Plugins and Internet ChatGPT Plugins groupings, since several plugins blurred the line between live search, page reading, and content extraction.
Before plugins, ChatGPT was constrained to data inside its training cutoff and could not look anything up after that date. Search oriented plugins solved this problem by routing user questions to a real search engine, then feeding the page text or snippets back into the model so it could answer with current information and surface direct links to source material. The category included OpenAI's own first party Browse with Bing plugin and a long tail of third party offerings such as WebPilot, Link Reader, BrowserOp, and Scraper.
OpenAI announced ChatGPT plugins on March 23, 2023, describing them as tools that would help ChatGPT "access up-to-date information, run computations, or use third-party services."[1] At launch the company shipped two of its own plugins, a code interpreter and a web browsing tool, alongside partners that included Expedia, FiscalNote, Instacart, KAYAK, Klarna, Milo, OpenTable, Shopify, Slack, Speak, Wolfram, and Zapier.[1][2] Access began in alpha for a small group of developers and Plus subscribers on a waitlist.
On May 12, 2023, OpenAI began rolling out the plugin system more broadly to ChatGPT Plus subscribers and removed the waitlist over the following week. By that point the catalogue had grown to more than 70 third party plugins, several focused on web search and URL reading.[3] The store eventually held more than 1,000 entries before OpenAI announced its end.
At launch ChatGPT could not browse the open web on its own. The model relied on a training snapshot with a cutoff in late 2021 for the original GPT-4 release. Search engine plugins bridged that gap by acting as an intermediary between the chat interface and live web sources. Each plugin exposed a small API described by an OpenAPI specification and a manifest file at /.well-known/ai-plugin.json.[4]
A search engine plugin followed the same pattern as any other plugin. The developer hosted an HTTPS endpoint that handled web search or page retrieval, then published a JSON manifest and an OpenAPI document describing the routes. At runtime ChatGPT decided whether the prompt warranted calling the plugin, issued a request to its API, and incorporated the JSON response into the reply.
For a typical search query, the flow looked like this:
search or fetch endpoint with a query string or URL.Browse with Bing produced inline citations as numbered hyperlinks. Third party plugins like WebPilot and Link Reader returned page summaries with their own formatting, while tools like Scraper extracted raw HTML elements. The browsing tool was deliberately limited to GET requests to reduce safety risk and keep the plugin from performing transactional actions on the user's behalf.[1]
The headline search plugin during the era was OpenAI's own browsing tool. Internally it began as a generic "Browsing" beta and was renamed Browse with Bing on the way to broader release, reflecting the underlying use of the Bing Search API.[5] Microsoft announced at Build 2023 in May that Bing would be the default search engine inside ChatGPT for users with browsing enabled, deepening the partnership that began earlier in the year with Bing Chat.[6]
Browse with Bing rolled out to ChatGPT Plus subscribers as part of the broader May 12, 2023 plugin release.[3] When enabled, the plugin gave ChatGPT a text only browser that could fire searches, click links, and scroll pages. Responses included numbered citations that linked back to the underlying Bing results, which made it easier for users to verify claims and follow source material.
The feature ran into trouble in early July 2023. Users discovered that Browse with Bing could be coaxed into reproducing the full text of paywalled articles, including subscription only news content. On July 3, 2023, OpenAI disabled the plugin "out of an abundance of caution" while it worked on safeguards.[7] The pause lasted nearly three months. Browse with Bing was reactivated for ChatGPT Plus and Enterprise users on September 27, 2023, with stricter handling of restricted content and clearer source citations.[8]
After the relaunch, OpenAI gradually folded the browsing tool into the core ChatGPT product, eventually exposing it to free users and bundling it under the simpler "Browse" label. By the time the plugin platform shut down, web browsing had moved from a discrete plugin to a built in feature, available without any install step.
Beyond the first party offering, dozens of third party plugins competed in the search engine and web reading category. The four most widely cited examples during the plugin era are summarised below.
| plugin | developer | role | notable points |
|---|---|---|---|
| WebPilot | webpilot.ai | URL reader and web search assistant | Submitted in April 2023, listed in the store from May 2023, removed for review and relaunched on July 18, 2023.[9][10] |
| Link Reader | gochitchat.ai | URL summariser supporting many file formats | Popular browsing aid; quietly disappeared from the plugin store around August 2023 without an official explanation.[11] |
| BrowserOp | feednews.com | Real time web search and multi URL reading | Previously named BrowserPilot before rebranding to BrowserOp.[12] |
| Scraper | api.gafo.tech | Static page scraper for text, links, and images | Marketed as a no code alternative to Python scraping libraries; limited handling of JavaScript heavy pages.[13] |
WebPilot was one of the first third party browsing plugins to reach scale. The team submitted the plugin in April 2023 and it appeared publicly soon after the May 2023 plugin store rollout.[9] Users could paste one or more URLs into a chat and ask WebPilot to summarise the page, rewrite the text, translate it, or pull out specific facts. The plugin could also run general web searches, allowing ChatGPT to answer questions about events that happened after its training cutoff.
WebPilot was briefly delisted in July 2023 during an OpenAI plugin review period. The developer later wrote about the impact of that review on its user experience and confirmed that the plugin returned to the store on July 18, 2023.[10] After the plugin platform was deprecated, the team continued the product as a Custom GPT on the GPT Store and as a standalone Chrome and Edge extension.
Link Reader, built by gochitchat.ai, focused on summarising the contents of arbitrary URLs. It supported web pages plus a wide range of file types, including PDFs, presentations, and spreadsheets, which made it useful for research workflows. During the second quarter of 2023 it was a frequent recommendation in lists of top ChatGPT plugins.
In August 2023 the plugin disappeared from the store without notice. Reporting at the time suggested the removal might be linked to OpenAI's wider concerns about plugins reproducing copyrighted material, the same concerns that led to the temporary disabling of Browse with Bing.[11] OpenAI never published an official explanation, and the developer did not return the plugin before the platform shut down.
BrowserOp was launched as BrowserPilot before being renamed.[12] Its developers positioned it as a fast, customisable browsing assistant that could pull real time information from search engines, summarise web pages, and process multiple URLs in a single request. Like WebPilot, it could also handle text rewrites and translations, blurring the line between a search plugin and a general purpose web utility.
Because BrowserOp could open many pages in one call, users sometimes reached for it when comparing reviews, prices, or news coverage across sites. After the plugin platform's shutdown in 2024 the project continued as a Custom GPT on the GPT Store.
Scraper, by api.gafo.tech, was the most data extraction focused plugin in the category. Rather than answering a search query in natural language, Scraper let users provide a URL and ask ChatGPT to pull out specific structured elements: paragraphs of body text, anchor links, images, headings, and so on. Tutorials at the time presented it as a no code alternative to Python libraries such as BeautifulSoup, with prompt engineering replacing CSS selectors.[13]
Scraper's main limitation was that it could only see the static HTML returned by a page. Sites that loaded most of their content through JavaScript or that were guarded by anti bot defences returned little or no useful data. Even with those constraints, the plugin became a popular choice for one off scraping tasks during the plugin era.
OpenAI's plugin store grouped extensions loosely, and several search oriented plugins also appeared under Web Development ChatGPT Plugins and Internet ChatGPT Plugins. WebPilot, BrowserOp, and Link Reader could answer factual queries with web sourced information, which placed them with search engines, but could also fetch a specific URL and pull out structured data, which placed them with web development or internet utilities. Scraper sat closer to the web development end of the spectrum, while Browse with Bing was the clearest pure search tool. Any single category list from this period is therefore incomplete; what each plugin actually did matters more than where the store filed it.
A search engine plugin had three required pieces.[4]
| component | format | purpose |
|---|---|---|
| HTTPS API | any backend stack | Implements the search or fetch endpoints used by the plugin. |
| OpenAPI document | YAML or JSON | Describes the routes, parameters, and response shapes. |
| Plugin manifest | JSON at /.well-known/ai-plugin.json | Lists name, description, logo, auth method, and the URL of the OpenAPI document. |
When a user installed a plugin, ChatGPT downloaded the manifest, read the OpenAPI specification it pointed to, and built an internal description of the available tools. There was no persistent state between calls and no way for a plugin to read or write conversation history beyond what was passed to it directly. For search plugins the most common shape was a single search route that accepted a query string and returned result objects with titles, URLs, and snippets, often paired with a fetch or read route that accepted a URL and returned the cleaned page text.
On November 6, 2023, OpenAI announced Custom GPTs at its first DevDay event. GPTs let users build branded versions of ChatGPT with their own instructions, knowledge files, and tool integrations through a feature called actions. Actions used the same OpenAPI mechanism as plugins, which made GPTs a near drop in replacement for plugin functionality. The GPT Store opened on January 10, 2024.
On March 19, 2024, OpenAI stopped allowing new conversations with plugins, including the search engine category. Existing chats with plugins continued to work for a short window. On April 9, 2024, all plugin chats were shut down and the plugin store was retired.[14] By that point most of the search functionality had migrated either into native ChatGPT features such as the integrated browsing tool, or into Custom GPTs on the GPT Store.
The table below summarises the lifecycle of the search engine plugin category.
| date | event |
|---|---|
| March 23, 2023 | OpenAI announces ChatGPT plugins, including a first party browsing tool. |
| May 12, 2023 | Plugin store opens to ChatGPT Plus subscribers; 70+ plugins available. |
| July 3, 2023 | Browse with Bing temporarily disabled over paywall reproduction concerns. |
| July 18, 2023 | WebPilot returns to the plugin store after a review period. |
| August 2023 | Link Reader disappears from the plugin store. |
| September 27, 2023 | Browse with Bing returns after roughly three months offline. |
| November 6, 2023 | OpenAI announces Custom GPTs at DevDay. |
| January 10, 2024 | GPT Store launches. |
| March 19, 2024 | New conversations with plugins are blocked. |
| April 9, 2024 | Existing plugin conversations end; plugin store retired. |
Many of the plugins continued in some form after the shutdown. WebPilot and BrowserOp both relaunched as GPTs on the GPT Store and as standalone browser extensions or APIs. Browse with Bing was absorbed into ChatGPT itself as a default capability, eventually replaced by OpenAI's own search index in later iterations.
Search engine ChatGPT plugins were the first widely used way to give a large language model live access to the open web inside a consumer product. They demonstrated that retrieval augmented chat could work at scale, and they introduced the design pattern of declaring a tool with an OpenAPI document so that a model could decide when to call it. That pattern became the basis for actions in Custom GPTs, for tool use in the OpenAI Assistants API, and for many of the agent frameworks that followed. The category also exposed practical limits: Browse with Bing reproduced paywalled content, Link Reader disappeared without explanation, and scraper plugins struggled with dynamic pages. Those tensions still shape how today's chat products handle web search, citation, and copyright.
