The visual builder for ChatGPT

Your API.
A useful app
in ChatGPT.

Turn a status lookup, a product search or a service request into a useful conversation. Connect OpenAPI or MCP tools. Build and test the experience visually.

From source to conversation

One useful task.
A clear path to build it.

Explore the stages below. This demonstration uses sample data and makes no external calls.

Illustration · Source review

Showing Connect your source example.

Start with a real task

Less searching.
More getting things done.

Your API brings the information. Your app gives people a useful way to act on it.

Support teams

Give every request a clear next step.

“Where is my access request?”

REQ-2048

In review · Team approval next

Operations teams

Find the record. Keep the context.

“Find the delivery for order 1082.”

Order 1082

Dispatch date · Delivery details

Product teams

Help people choose with confidence.

“Which plan fits a team of five?”

A guided comparison

Requirements · Options · Next step

Illustrative ideas, using sample data. Available actions depend on the tools you connect.

Made for the whole workflow

Go beyond the first prototype.

Connect, design, test and prepare a release in one workspace. Keep control of what your app can do at each step.

Visual builder

Give the task a useful interface.

Drag, drop and arrange thirteen component types. Start from five featured templates or review an AI-generated plan.

OpenAPI import

Start with an API you already have.

Inspect OpenAPI 3.0 or 3.1 JSON. Test a supported public GET operation and review its tool contract before creating a draft.

OpenAPI guide

Existing MCP servers

Bring your existing tools along.

Inspect an HTTPS MCP server and explicitly test selected tools. Saved connection credentials are encrypted.

MCP guide

Preview and replay

See the conversation before release.

Review simulated actions locally. Record and replay sessions without executing external actions during playback.

Testing guide

Release history

Keep a version you can return to.

Compare immutable releases and roll back from a compatible saved bundle while preserving your current draft.

Release guide

Export and submission

Prepare the next step with clarity.

Export a portable Plugin package and prepare a submission dossier. Track distribution evidence separately from deployment.

Before you build

A few things
worth knowing.

A clear starting point, from your first connection to your first release.

Who is DraftYourApp for?

Teams with an API, an MCP server or a workflow they want to make useful inside ChatGPT. Start with one focused task, such as looking up a request or finding a product, then design the experience around it.

Do I need to write code?

You can arrange the interface visually and start from templates. Connecting a real service still requires a working API or MCP server, access to its documentation and permission to use it. DraftYourApp helps you review the contract and test supported tools.

What can I connect?

Import OpenAPI 3.0 or 3.1 JSON and test a supported public GET operation, or inspect an existing HTTPS MCP server and explicitly test selected tools. Review each tool’s inputs and outputs before creating your draft.

Will the demo or replay change real data?

The walkthrough on this page uses sample data only. In the builder, preview and replay use simulated or recorded results. Remote tool tests are separate and require your explicit confirmation; review the selected tool before running one.

Does deploying publish my app in ChatGPT?

Deployment creates a technical release. OpenAI submission, approval and publication are separate steps. DraftYourApp helps you prepare a submission dossier and track evidence, but deployment does not guarantee approval or publication.

Can I start for free?

Yes. The Free plan includes one application, two saved connections and ten AI generations per day. Move to Pro when you need higher limits; the current available price is shown in the pricing section.

Build the task your users keep asking for.

Bring a useful API. Shape a focused experience. Give your users a better way to get things done in ChatGPT.
