Custom GPTs: Shareable ChatGPTs Anyone Can Make

Custom GPTs let you package ChatGPT with instructions, files, and tools. Look at whether anyone actually uses them outside of demos.

22 min · Reviewed 2026

Custom GPTs launched in November 2023 as a way to package ChatGPT with custom instructions, knowledge files, and optional actions (API calls). OpenAI opened a GPT Store in 2024 where anyone could publish one. By April 2026 there are millions of Custom GPTs, but the honest reality is most of them are abandoned and the store is dominated by a few dozen popular ones.

What it's genuinely good at

Packaging instructions plus files into a reusable ChatGPT tuned for one task.
Sharing internally — 'use the Legal Review GPT' is easier than pasting a system prompt.
Actions — Custom GPTs can call your API, turning ChatGPT into a light agent.
No-code — built via chat; non-developers can make one in 10 minutes.
Discoverability through the Store for genuinely novel use cases.

What it struggles with

GPT Store is a graveyard — most GPTs have no users and no updates.
System prompt leakage — clever users can extract your instructions, so 'proprietary prompts' aren't really secret.
Monetization is thin — OpenAI's promised revenue-share has been limited and slow.
Version control is manual — no git history for changes.
Custom GPTs often feel worse than default ChatGPT because their instructions constrain the model's flexibility.

Pricing (April 2026)

Creating: Free on any ChatGPT Plus, Pro, Team, or Enterprise plan.
Using: Plus users can use any public GPT, Free users get a smaller quota.
Publishing to the Store: Free.
Revenue share: Still invite-only, minimal payout for most creators.

Who should bother: teams wanting internal reusable assistants, tinkerers exploring agent patterns, educators packaging a tutor for students. Who shouldn't: anyone hoping to build a business on Custom GPTs — the Store economy isn't there. For serious applications, build on the API or use Anthropic's Projects instead.
