Make demo videos
from Claude or ChatGPT

Ask the way you’d ask a teammate: "make a demo of our new onboarding." Demosmith opens your product, clicks through it, and sends the finished video back to your chat, with a voiceover and captions.

Example demos of products you know, drawn to show what you get back. Demosmith is not affiliated with these companies, Anthropic, OpenAI or Cursor.

The difference

Can ChatGPT and Claude make videos?
Now they can make yours.

On their own, ChatGPT and Claude can write you a demo script. They can’t open your product and record it. Connect Demosmith and they hand back the finished video instead.

Without Demosmith
Make a demo video of our booking flow
I can’t record your product, but here’s a script you could film:
Scene 1. Open the booking page. Scene 2. Pick a date and a time. Scene 3. Confirm, and show the email…

Still up to you: record your screen, edit the footage, then write and record a voiceover.

With Demosmith
Make a demo video of our booking flow
Your demo video is ready.

Still up to you: nothing. Watch it, then share the link.

How it works

Three steps.
No screen recording.

1

Connect Demosmith once

Add Demosmith to Claude, ChatGPT or your coding agent and sign in. You only do this the first time.

2

Ask for the demo you need

Your assistant already knows your product, so say what to show: "our onboarding", "the feature we shipped today", or "the same demo in Spanish".

3

Get the video in your chat

Demosmith records your product, edits it and adds a voiceover. The finished video comes back with a link to watch or download.

the question everyone asks

What if my product
needs a password?

The demo pauses and your assistant sends you a private link. You type the password on Demosmith’s own page, not in the chat, so your assistant never sees it.

A free check before every demo No passwords in the chat Disconnect any time
What you get

A finished video,
ready to send.

The demo you get from a chat is the same one the Demosmith app makes. Nobody has to edit it afterwards.

A voiceover in 31 languages

Ask for the language, voice and tone in the same message.

Captions and zooms

Captions match the voiceover, and the video zooms in on every click so viewers know where to look.

Ready to share

A link to watch and a download, right in the chat.

Saved in your Demosmith library

Every demo is labelled with the assistant that asked for it. Change the script, voice or language there, share it or download it.

What teams ask for
once it’s connected

Your assistant already knows your product, so a short request is enough. Copy one into your chat.

Launch dayMake a demo video of the feature we shipped today, for the changelog and the launch post.
OnboardingMake a demo of our onboarding, from sign-up to creating the first project.
Sales follow-upMake a short demo of our reporting dashboard I can send to a prospect after today’s call.
Help centreMake how-to videos for inviting a teammate, changing their role and resetting a password.
New marketsMake our onboarding demo again in Spanish, French and German.
In Claude Code, Codex or CursorOnce this branch is on staging, make a demo of the new checkout flow.
Setup

Add the Demosmith MCP
to your AI assistant

You need a paid Demosmith plan. Every assistant connects to the same URL:

https://mcp.demosmith.ai/mcp

Claude

  1. In Claude, go to Customize, then Connectors.
  2. Click + Add, then Add custom connector.
  3. Name it Demosmith, paste https://mcp.demosmith.ai/mcp and click Continue.
  4. Keep the sign-in settings Claude suggests and click Add.
  5. Click Connect, sign in to Demosmith and allow access. Then ask for a demo in any chat.

On a Claude Team or Enterprise plan, an owner adds Demosmith once under Organization settings, then Connectors. Everyone else clicks Connect next to it in Customize, then Connectors.

ChatGPT

  1. In ChatGPT on the web, go to Plugins.
  2. Click the + button, then Add custom MCP server.
  3. Name it Demosmith and paste https://mcp.demosmith.ai/mcp under Connection.
  4. Choose OAuth for authentication, tick the box to confirm the warning, then click Create as a plugin.
  5. Install the plugin, then sign in to Demosmith and allow access. In a new chat, type @Demosmith and ask for a demo.

This works on ChatGPT Business and Enterprise, where an admin or owner adds Demosmith once for the whole workspace. ChatGPT Plus and Pro only allow read-only connections, so they can’t start a demo. Use Claude, Claude Code, Codex or Cursor there instead.

Claude Code

  1. Add Demosmith from your terminal:
    claude mcp add --transport http demosmith https://mcp.demosmith.ai/mcp
  2. In Claude Code, type /mcp, pick demosmith and sign in to Demosmith.
  3. Ask for a demo, or for one after each deploy.

Codex

  1. Add Demosmith to ~/.codex/config.toml:
    [mcp_servers.demosmith]
url = "https://mcp.demosmith.ai/mcp"
  2. Sign in to Demosmith from your terminal:
    codex mcp login demosmith
  3. Ask Codex for a demo, or for one after each deploy.

The Codex app, CLI and IDE extension share this setup, so you only do it once.

Cursor

  1. Create an API key on the Developers page in Demosmith.
  2. Add this to ~/.cursor/mcp.json, with your key in place of YOUR_API_KEY:
    {
  "mcpServers": {
    "demosmith": {
      "url": "https://mcp.demosmith.ai/mcp",
      "headers": { "Authorization": "Bearer YOUR_API_KEY" }
    }
  }
}
  3. Ask Cursor’s agent for a demo.
Questions

Questions people ask

Every paid Demosmith plan includes it, from $40 a month. A demo made from a chat uses the same AI minutes as one made in the app, and the check before it is free. Compare plans

ChatGPT makes images but no longer makes video of its own since OpenAI closed Sora, and it can’t open your product and record a demo of it. Connect Demosmith and it can. Ask for a demo in a chat and you get a narrated video of your real product. This works on ChatGPT Business and Enterprise. More in our guide to whether ChatGPT can make videos.

Not by itself. Add Demosmith as a custom connector and Claude can make a narrated demo video of your product and give you the link in the same chat. Custom connectors work on every Claude plan, and the free plan allows one. Our guide to Claude connectors and MCP walks through it.

MCP, the Model Context Protocol, is the open standard AI assistants use to connect to other apps. The Demosmith MCP server is what lets Claude, ChatGPT, Claude Code, Codex and Cursor ask Demosmith for a demo video. You add it once, sign in, and from then on you ask in plain words.

In Claude Code, run claude mcp add --transport http demosmith https://mcp.demosmith.ai/mcp, then type /mcp to sign in. In Codex, add the URL to ~/.codex/config.toml and run codex mcp login demosmith. In Cursor, add the URL and your Demosmith API key to ~/.cursor/mcp.json. The setup tabs on this page have every step to copy, and our MCP setup guide covers team sharing and fixes.

ChatGPT Business and Enterprise, on the web. An admin or owner adds Demosmith once for the workspace, then everyone can use it. ChatGPT Plus and Pro only allow read-only custom connections, which can’t start a demo.

No. If Demosmith needs a login or a verification code, the demo pauses and your assistant gives you a private link. You type it on Demosmith’s own page. Your assistant never asks for it, and it never appears in the chat.

It comes with every paid Demosmith plan: Starter at $40 a month, Pro, Business and Enterprise. A demo made from a chat uses the same AI minutes as one made in the app, based on the length of the finished video. The check before each demo is free. The 3-day trial doesn’t include it. See pricing.

Yes. The demo keeps going without the chat. Ask about it later, in the same chat or a new one, and your assistant picks it up and gives you the video when it’s ready.

Any of the 31 languages Demosmith narrates and captions in, including Spanish, French, German, Japanese, Portuguese and Arabic. Say the language in your message, along with a voice or tone if you have a preference.

No. From an assistant, Demosmith makes the narrated demo video. Interactive demos, docs, social clips and product films are made in the Demosmith app.

Open the Developers page in Demosmith and disconnect it. You can also remove Demosmith from the assistant itself.
