Keymate.AI GPT (Beta) is the listing name in the GPT Store for Keymate AI Search & Browse with Linked Memory, a third-party tool that adds real-time web search, URL browsing, and a persistent knowledge base to ChatGPT.[1] It was developed by Keymate.AI, a company founded by Ozgur (Oscar) Ozkan and Utku Boratach, and was first distributed as a ChatGPT plugin during OpenAI's plugin program in 2023 before being migrated to a custom GPT and a broader knowledge-management product at keymate.ai.[2][3] The "Beta" suffix dates to the ChatGPT plugin era, when third-party plugins were themselves an OpenAI beta feature; the label persists in the GPT's permalink slug (keymate-ai-gpt-beta).[1]
Keymate.AI Search was created to address a limitation of ChatGPT prior to native browsing: out of the box, the model could not retrieve information from the open web beyond its training cutoff, and could not consult specific URLs supplied by the user. The plugin closed that gap by routing a query through Keymate.AI's own backend, which used Google search to fetch and rank current results and then returned the most relevant content to ChatGPT for synthesis.[4][5] A distinguishing feature relative to OpenAI's own browsing plugin, which was built on the Bing search API, was Keymate.AI's use of Google results.[4][6]
In its plugin form the tool was referred to internally as internetSearch, and it could be invoked either by naming it or through slash commands such as /search, /browse, /fast, and /list.[7] Beyond search it also offered a Personal Knowledge Base for storing and querying user content, an early form of the persistent-memory features that the product later expanded.[7]
Keymate.AI Search launched during the ChatGPT plugins beta in 2023, when OpenAI opened a marketplace of third-party plugins to ChatGPT Plus subscribers.[4] The plugin was among the early entries vetted by OpenAI; its founder described it as the 31st of 60 verified plugins and characterized the tool as "powered by Google's first 10 results and smart web crawlers."[2] Contemporaneous community write-ups treated it as one of the more widely used web-search plugins, with multiple Medium tutorials, a user guide published by the founder on LinkedIn, and an entry in the community-maintained awesome-chatgpt-plugins repository on GitHub.[5][7] During the same period Keymate.AI also shipped an iOS keyboard app that combined Google search with GPT-4.[2]
After OpenAI announced custom GPTs and the GPT Store in late 2023, the Keymate.AI team published the search functionality as a custom GPT. The GPT, titled "Keymate AI Search & Browse with Linked Memory," was added to the store on November 23, 2023 and was still being updated as of February 28, 2025.[1] Third-party GPT directories list it with a rating of roughly 4.1 out of 5 across a reported 100K-plus conversations, figures that are self-reported through those listings rather than published by OpenAI.[1]
The product also expanded beyond simple web search into a broader workspace branded Keymate.AI at keymate.ai, which the company describes as "an AI workspace that remembers, organizes, and answers - using your curated sources."[8] Users can add sources such as PDFs, Google Docs, YouTube videos, and web pages, organize them into collections, and query them in plain language with cited answers.[8] The ChatGPT integration, marketed as "KeymateGPT," remains a documented offering, alongside a Make.com integration, a Chrome extension, and an email-to-collection feature that assigns each collection a unique address for automated ingestion.[9][10]
During its plugin period, Keymate.AI GPT (Beta) was characterized by the following capabilities, as described in the developer's documentation and contemporaneous third-party reviews.
| Capability | Description |
|---|---|
| Real-time web search | Retrieved fresh results from Google and surfaced them to ChatGPT for reading and quoting.[4][5] |
| Result depth controls | The numofpages parameter could be raised to as many as 6 to return more links, while a percentile parameter shortened or lengthened the returned text.[7][11] |
| Filtered search | Results could be narrowed by date, language, and location for current or geographically specific tasks.[11] |
| Browse by URL | The tool could fetch and summarize a specific URL on request, an early analogue of ChatGPT's later native browsing.[5] |
| Personal Knowledge Base | Commands such as /savetopkb, /insert, /upsert, /pdfload, and /pdfsearch let users store and search their own content, including uploaded PDFs.[7] |
According to community documentation, the plugin returned the first five Google results with summarized HTML, and provided the full HTML content of the first three, giving ChatGPT enough material to answer with current context.[5] The percentile and numofpages parameters let users trade off between breadth of sources and length of returned text.[7][11]
The Personal Knowledge Base distinguished Keymate.AI from search-only plugins by letting the model write to and read from a user-specific store. In the later custom GPT, this matured into a command-driven memory layer connecting ChatGPT to a user's saved "memory" and "collections," with documented commands including /save, /recall, /link, /unlink, /list, /search, /browse, and /help.[9] The GPT also advertises the ability to search an academic database of more than 400 million PDF research papers.[1]
Reviewers and tutorial authors described the tool as useful for tasks that benefited from current web information layered on top of ChatGPT's reasoning, including:
The ChatGPT plugins program in which Keymate.AI GPT (Beta) originally launched was retired by OpenAI on April 9, 2024 in favor of the GPT Store and the broader custom GPTs ecosystem.[6] The Keymate.AI brand remains active at keymate.ai, with its current product centered on a structured AI workspace and the "KeymateGPT" ChatGPT integration rather than the original beta plugin form factor.[8][9] The name "Keymate.AI GPT (Beta)" is therefore best understood as a historical label, preserved in the GPT Store listing, that ties the current GPT back to the early ChatGPT plugin era.
