GPT Shop Keeper is a Custom GPT for ChatGPT published in the GPT Store. The GPT presents itself as a fantasy tavern shopkeeper that helps users browse, discover, and select other Custom GPTs based on the task they want to accomplish. It is one of the most well known third party Custom GPT discovery tools, predating the official OpenAI Custom GPT search experience that launched alongside the GPT Store on January 10, 2024.
GPT Shop Keeper is built by Mind Goblin Studios, the creative studio run by developer Nick Dobos. It is part of the GPTavern collection, a themed family of Custom GPTs that share a fantasy tavern setting and a common set of hotkey commands. Other GPTs in the same collection include Grimoire (a coding wizard), Researchoor (a research and learning copilot), Cauldron (an image blending and editing tool), and Fortune Teller. The Shop Keeper acts as the in fiction merchant who guides visitors to the rest of the tavern.
The role of GPT Shop Keeper is recommendation rather than direct task completion. When a user describes a problem, the GPT does not try to solve it itself. Instead, it brainstorms several search queries, runs them through its browsing tool against the public ChatGPT GPT URL space, and surfaces a set of Custom GPTs that look like good matches. Each result is presented with a name, a short description, a direct link, and a pair of suggested conversation starter prompts the user can copy into the recommended GPT.
The shopkeeper persona is described in the assistant's instructions as "more than a simple apothecary merchant; a confidant to the townsfolk and travelers from distant lands." Greetings, hotkey labels, and error messages are framed in tavern language. Users can ignore the framing and treat the assistant as a plain search interface, or lean into it and use the "have a drink at the tavern" hotkey to meet the other GPTavern characters.
The GPT is free to use and is available to any ChatGPT account that can access Custom GPTs. Like other Custom GPTs in the GPT Store, it runs on the GPT-4 family of models. The infobox lists v1.6 as the published version, while the system prompt published by users in early 2024 still labels itself as v1.0; the version string has been updated as the developer tuned the instructions over time.
When OpenAI introduced Custom GPTs at DevDay on November 6, 2023, there was no built in way to search the growing catalog of GPTs that creators were publishing. Discovery happened mostly through Twitter, Reddit, and a handful of independent directory websites. Several builders responded by making Custom GPTs whose only job was to recommend other Custom GPTs.
GPT Shop Keeper is one of the earliest and most widely shared examples of that pattern. It was published in the weeks between the November 2023 announcement and the official launch of the GPT Store on January 10, 2024. By the time the official store opened, the Shop Keeper had already accumulated thousands of conversations and was being passed around online as a workaround for OpenAI's missing search feature.
The broader GPTavern project is the work of Nick Dobos, an iOS developer who previously worked at Twitter. Dobos is also the creator of Grimoire, a coding focused Custom GPT that he has described as one of the most used GPTs in the store. Mind Goblin Studios is the umbrella under which he ships his AI projects, including the GPTavern web directory at gptavern.mindgoblinstudios.com.
The Shop Keeper follows a fairly opinionated workflow encoded in its system prompt. The flow follows the same pattern on every new request:
site:chat.openai.com/g, restricting results to the public ChatGPT Custom GPT URL space.The instructions are explicit that the model should never invent GPT URLs or descriptions and should only display details returned by the browsing tool. If a user reports a broken or hallucinated link, the assistant is told to regenerate rather than fabricate a replacement. The design intent is grounded retrieval rather than freeform generation.
The four hotkeys are part of the Shop Keeper's core interaction model. They are rewritten into shopkeeper voice in each reply, but the underlying behaviors are fixed:
| Hotkey | Action |
|---|---|
| W | Browse the web for more GPTs using a query similar to the previous one |
| A | Explore related and complementary GPTs by writing new queries that branch out into adjacent categories |
| S | Generate more sample conversation starters for the GPTs already recommended |
| T | Open the tavern. Read the bundled GPTavern.md knowledge file and recommend each of the listed GPTavern members in turn |
The T hotkey is the one that ties Shop Keeper into the rest of the GPTavern collection. When the user presses T, the assistant pulls up the knowledge file, displays its full contents, and walks through each tavern member with a short pitch and a link.
The first reply in a new conversation follows a strict template. The assistant prints a stocking shelves animation, a short ASCII art string, the line "Inventory: loaded" with two emoji, and "Shop v1.0 is now open." It warns the user that links can occasionally break and asks them to regenerate if a result returns an error. After the introduction, the assistant immediately moves into the brainstorm and search loop. Subsequent turns skip the introduction.
GPT Shop Keeper advertises the standard set of Custom GPT capabilities exposed by the GPT Builder. According to its store listing and system prompt, the following tools are enabled:
| Capability | Enabled | Notes |
|---|---|---|
| Web browsing | Yes | Primary tool. Used on almost every turn to search site:chat.openai.com/g |
| DALL-E image generation | Yes | Rarely used in normal flow. Some users invoke it for tavern themed avatars |
| Code interpreter | Yes | Available for users who ask the GPT to run scripts or compute statistics on results |
| Knowledge files | Yes | Ships with GPTavern.md, which lists the other GPTs in the collection |
| Custom actions | No | The GPT does not call any external API beyond browsing |
Because the recommendation flow depends on live web search, the GPT cannot meaningfully be used in environments where browsing is disabled.
The GPTavern.md knowledge file is the source of truth for the T hotkey. It contains a hand maintained list of GPTs in the GPTavern family along with one line summaries. Members documented on the GPTavern website include featured patrons (Grimoire, Gifpt, Researchoor, Cauldron, Fortune Teller), CognoEmo Tools (Emotion Shaman, Soothe Sayer, Exec f(x)n), Agents and Tech Experiments (Tricycle, AgiDotZip, BabyAGiTxt, BabyAGiSQL), Custom GPT building tools (Evolution Chamber, Spellbook: Hotkeys, Carrier Pigeon), Psychonaut tools (Meditation, Walking Meditation, Hypnotist), and Perpetual Stew. The file is updated by Mind Goblin Studios as the collection grows.
The four conversation starters surfaced on the Shop Keeper's profile in the GPT Store map onto common ways users engage with the GPT.
| Starter | Intent |
|---|---|
| Lets have a drink at the tavern, introduce GPTavern.md members | Triggers the T hotkey. The assistant reads the knowledge file and walks through each GPTavern member |
| Featured: Who is visiting the tavern today? | Asks for a curated rotation of recently popular or featured GPTs from the collection |
| Coding | Keyword starter. The assistant brainstorms coding queries and searches for matching Custom GPTs, typically including Grimoire |
| Art & design | Keyword starter focused on creative tooling. The assistant searches for image, design, and illustration GPTs |
Users are not limited to these starters. Any natural language request describing a workflow or task is a valid prompt; the starters exist mostly as an onboarding aid.
The full system prompt for GPT Shop Keeper has been published openly by users who reverse engineered Custom GPTs from the GPT Store in early 2024. It is mirrored in two community repositories: LouisShark's chatgpt_system_prompt GitHub project and linexjlin's GPTs GitHub project. Both copies match and reflect the v1.0 instructions.
Key directives in the prompt include:
site:chat.openai.com/g combined with the brainstormed keywords.The Shop Keeper is most useful when a user knows roughly what they want to do but does not know which Custom GPT, if any, exists for that purpose. Common use cases include:
| Use case | What the user asks | What the Shop Keeper does |
|---|---|---|
| Find a coding helper | "I need help refactoring TypeScript" | Searches for coding focused GPTs, usually surfaces Grimoire and a handful of language specific assistants |
| Find an image generator | "I want to generate fantasy character art" | Searches for image and design GPTs, returns a mix of DALL-E wrappers and stylized illustration GPTs |
| Discover writing tools | "Help me find a GPT that edits academic papers" | Brainstorms academic writing keywords, returns editor and proofreading GPTs |
| Browse the GPTavern | "Lets have a drink at the tavern" | Reads the bundled knowledge file and recommends each GPTavern member with their tagline |
Because the GPT is fundamentally a search wrapper, its quality depends on what is publicly indexable in the ChatGPT GPT URL space at any given time.
GPT Shop Keeper has the same limitations as any Custom GPT that depends on browsing for its core functionality. Issues users have reported in community discussions include:
site:chat.openai.com/g search depends on Bing indexing public GPT URLs. GPTs that are unlisted, recently published, or behind region locks may not appear at all.Despite these limits, GPT Shop Keeper appeared on most early lists of "useful Custom GPTs" that circulated on Twitter, Reddit, and AI newsletter sites in late 2023 and early 2024. The infobox figure of roughly 18,000 chats reflects an early 2024 snapshot taken by third party trackers. Reviews on catalog sites such as gptstore.ai and AIPRM are generally positive, highlighting the structured recommendation format, the included starter prompts, and the tavern theme.
