ChatGPT Apps vs GPTs: What's the Difference?

ChatGPT exposes a handful of related-but-distinct surfaces — apps, GPTs, connectors, and the underlying chat. People use the terms interchangeably, but they behave very differently in practice. This guide breaks down what each one is, when to reach for which, and why ChatGPTAppsRank ranks one category and not the others.

The short version

A ChatGPT app is a partner integration — a real third-party service (Canva, Figma, Wolfram, Spotify, Google Drive) wired into the chat surface so you can use it without leaving the conversation. You sign in to your real account, grant scopes, and the app then has access to your real data. Apps are stable, partner-vetted, and persist across conversations until you disconnect them.

A GPT is a custom assistant built inside ChatGPT's GPT builder. Anyone can make one. A GPT is essentially a prompt template — sometimes with attached files or a custom action — and it's designed to be focused on one task or persona. GPTs do not require third-party account linking for most use cases. They are great for narrowing scope; they are not how you connect to your Google Drive.

A connector is the underlying link between ChatGPT and a third-party account. Many connectors are surfaced as apps with their own interface inside chat; others operate silently in the background, providing data context to whatever you are asking. The line between a connector and an app is fuzzy — and getting fuzzier as OpenAI consolidates the surfaces.

An AI tool in our vocabulary is anything else — an external SaaS product that happens to use AI, lives on its own website, and is not accessible inside ChatGPT. ChatGPTAppsRank does not rank those.

When to use which: a decision tree

Do you need ChatGPT to read or write to a real account on a real service? If yes — your Google Drive, your Slack workspace, your Canva brand kit — you need an app. A GPT cannot do this for you. A connector might already exist for the service in question, in which case it's the same thing wearing a different label.

Do you need a focused, repeatable assistant for a single well-defined task? A GPT is the right tool. Custom instructions, an attached reference file, and a consistent persona will get you further than trying to coax the default chat into the same behavior over and over.

Are you trying to fire a workflow in another tool you already own? That's still an app — usually an automation app like Zapier or Airtable. See the best ChatGPT apps for automation for the shortlist.

Looking for a tool that lives outside ChatGPT? That's an external AI tool, and outside the scope of this site. We rank apps that work inside ChatGPT — that's the bar.

Concrete examples

"Summarize my Q3 deals from HubSpot." That's an app job — specifically the HubSpot ChatGPT app. See the business category.

"Help me practice German grammar." That's a GPT job. There is no German-grammar SaaS the model needs to log into — it just needs to be a consistent tutor.

"Build me a Canva post about our new product." App — specifically Canva. The model needs to talk to your real Canva account to produce a brand-consistent file.

"Plot the Pareto distribution for these inputs." App — Wolfram, in the research category. Symbolic math is exactly the kind of thing the base model stumbles on.

Frequently asked questions

Frequently asked questions

Is a ChatGPT app the same as a plugin?
No. Plugins were the previous generation. Apps are the successor surface — deeper integrations with their own permissions, persistent connections, and richer capabilities. Most plugins have been retired in favor of apps and connectors.
Should I use an app or a GPT for the same task?
Use an app when you need to read or write to a real third-party service (your Google Drive, your Canva account, your Slack channel). Use a GPT when you need a focused, prompted assistant for a self-contained workflow that doesn't require external accounts.
Are connectors the same as apps?
They overlap. A connector is the underlying account link to a third-party service; some connectors are surfaced as full apps with their own UI inside chat, while others operate silently in the background. We rank connectors only when they behave as user-facing apps.
Why don't you rank GPTs?
GPTs are user-generated, change constantly, and are not gated by a partner agreement. Ranking them would be a fundamentally different exercise — closer to ranking individual prompts than ranking products. We focus on partner apps because they are stable enough to compare meaningfully.
Can I use multiple apps in one conversation?
Yes. You can call apps individually in a single chat, and ChatGPT can also route across them automatically when it makes sense. Each app keeps its own permissions and account context.
What about agents and Custom Agents?
Agents are a broader category that may chain multiple apps, GPTs, and tools together to complete multi-step tasks autonomously. From a ranking perspective, we score the underlying apps; how an agent orchestrates them is a separate question.
Our scope: ChatGPTAppsRank only ranks apps that work inside ChatGPT. We do not rank custom GPTs in the main rankings, and we do not rank generic AI tools. See the ranking methodology for what we score and how.
