What is a cross-LLM agent marketplace?
Plain answers to the questions professionals ask before installing their first AI agent — no jargon, no sales pitch.
What is an AI agent?
An AI agent is a configured, tool-using system built on top of a large language model (LLM) that can take multi-step actions to complete a real task — reading a spreadsheet, drafting a reply, updating a record — not just generate text. Unlike a raw LLM session, an agent has a defined role, a set of connected tools, and instructions that persist across the whole task. On FindAgent, every listed agent has been built and tested for a specific professional workflow, so the scope of what it can and cannot do is explicit before you install it.
What is the difference between an AI agent and a prompt?
A prompt is a single instruction you type into a chat window; it produces one response and stops. An AI agent is a durable, reusable configuration that wraps an LLM with a persistent role, tool access (APIs, file readers, web search), and structured logic that runs across many steps without you re-explaining the task each time. The practical difference is repeatability: a well-crafted prompt might produce a good invoice summary once, but a bookkeeping agent on FindAgent does the same job reliably every time, every week, with no re-prompting.
What is a cross-LLM agent marketplace?
A cross-LLM agent marketplace is a platform where you can discover, evaluate, and install AI agents that are compatible with more than one large language model runtime — so the same agent works whether you run it inside Claude, ChatGPT, Gemini, or Cursor. Most agent stores today are locked to a single platform: GPTs only run in ChatGPT, Claude Projects only run in Claude. FindAgent is designed specifically to break that lock — an agent listed here carries compatibility metadata so you install it into whichever LLM you already have open, without rebuilding anything. Learn more on the FindAgent homepage or in what an AI agent marketplace is.
Can I use the same AI agent in Claude and ChatGPT?
Yes — if the agent has been built to the cross-LLM standard that FindAgent enforces. Each agent in the marketplace declares which runtimes it supports, and the install flow gives you a version matched to your chosen LLM. The underlying logic, instructions, and tool connections are the same; only the thin integration layer differs between platforms. This means you can run a customer-support agent in Claude at your desk and the same agent in ChatGPT on your phone, with no duplicate setup.
How do I install an AI agent without coding?
On FindAgent, installing an agent is a guided process that requires no code: browse the marketplace, choose an agent, and follow the install flow that connects the agent configuration to your chosen LLM in the correct format. The agent creator has already handled the technical setup — tool permissions, system prompt structure, runtime-specific formatting — so you only make decisions about your own data and preferences. A solo accountant with no development background can have a working bookkeeping agent running inside Claude in minutes.
What is the difference between an AI agent and a chatbot?
A chatbot is reactive: it waits for a message, generates a reply, and stops. An AI agent is proactive and action-oriented: it can read inputs from external sources, make decisions, call tools, and complete multi-step workflows without a human steering every exchange. The distinction matters in practice — a chatbot can tell you how to reconcile a bank statement, but a bookkeeping agent on FindAgent can actually do the reconciliation, flag discrepancies, and draft a summary report as a single, automated task.
How do I find an AI agent for my specific job or industry?
FindAgent organises its marketplace by job function rather than by technology, so you search by what you need to get done — not by model name or API type. Browse by vertical to see agents built specifically for your role: bookkeeping and accounting, ecommerce operations, customer support, and more. Each listing includes a plain-language description of exactly what the agent does, which LLMs it supports, and what access it needs — so you can make an informed decision before you install anything.
