How to Turn a Real MCP Session Into a Demo Video Without Screen Recording

Why AI Chat Demos Are So Hard to Record Well

You built an MCP server, a ChatGPT app, or an agent skill. Someone can ask a question, your tool runs, and something useful appears.

Now you need a video that shows it.

You open a screen recorder, start a fresh conversation, and type your prompt. The assistant thinks. Your tool starts. A spinner turns. Eventually, the answer arrives.

The workflow worked. The video is mostly waiting.

That’s the awkward part of demonstrating products that live inside AI chats: a successful session and a good demo video have very different pacing.

The useful moment needs context
With a conventional app, you can often start a recording on the screen that matters. A dashboard already contains the chart. A search page already contains the results.

In a chat, the result makes sense because of what happened before it.

The viewer needs to see the request, understand that the assistant called your tool, and connect the response to the original question. Skip too much and the result seems disconnected. Include everything and the demo drags.

A screenshot loses that sequence entirely. It can show a useful answer, but it rarely explains how your product helped produce it.
Waiting is part of the product, but it dominates the recording
A real session includes several kinds of delay:

• The assistant deciding what to do.
• A tool fetching or processing data.
• Another tool running afterward.
• The assistant composing the final response. Those pauses might be reasonable while you’re using the product. You asked for something and expect to wait.

A viewer scrolling through a feed hasn’t made that investment. They’re waiting to discover whether the result is interesting.

You can trim the pauses in a video editor, but cuts can make the conversation jump. Speeding up the whole recording makes cursor movement frantic and text difficult to read.

The hard part is compressing the wait while preserving a clear sequence.

Re-recording changes the thing you’re recording
Fixing a conventional software demo is often straightforward: reset the app and repeat the clicks.

Repeating an AI conversation can produce a different session.

The assistant might write a longer introduction, choose a different tool sequence, or format the result differently. A request that worked during rehearsal might hit a timeout during recording.

Now a small correction—perhaps a typo in the prompt—requires another run with a different answer.

This makes recording surprisingly expensive. You’re trying to capture a useful interaction while also depending on that interaction to repeat.
Chat interfaces contain a lot you didn’t intend to show
The conversation is only one part of the screen.

There may also be account details, project names, previous chats, file paths, or notifications. Tool responses can contain information that was useful during development but inappropriate for a public demo.

Using a demo account and fictional data helps. You still need to inspect the entire frame, including expanded tool cards and anything revealed during scrolling.

A recording can be technically successful and still require another take because of something in the sidebar.

The result doesn’t always fit on screen
Chat responses grow downward. A useful answer may push the original request out of view. An expanded tool call can move the result below the fold.

That leaves you making presentation decisions while recording:

When should you scroll? Should the tool details stay open? How long does the viewer need to read the table? Which part deserves a closer look?

Those choices determine whether someone understands the demo. They’re difficult to make smoothly while also operating the product.
Editing needs to preserve what actually happened
Removing dead time is reasonable. Changing the outcome creates a different problem.

If you shorten a prompt, it should retain the original intent. If you compress a wait, viewers should understand that the video is edited. A tool result should reflect what the tool actually returned.

This matters especially when recreating a chat visually. A polished replay can resemble a live recording, so its relationship to the source session needs to be clear.

The editing process should make the real interaction easier to follow.
Why we built chat-replay
We built chat-replay around that distinction.

It takes a transcript from a real session and renders an edited replay using HyperFrames. Typing, tool calls, replies, scrolling, captions, and zooms run on a fixed timeline.

Each beat references its source transcript turns. Before rendering, the skill produces a script explaining what was shortened, cut, or merged for review.

The default disclosure reads “Recreated from a real session.” Waits can be compressed while retaining the original duration in labels such as “Thought for 9s.”

That gives us a repeatable way to present an interaction without running it again for every edit.

The current version has limits: Claude-style and Codex-style light layouts, 16:9 output, image-based widgets, and no built-in narration or music.

It’s free, open source, and available independently of the rest of promotion-agent:

npx skills add apsquared/promotion-agent --skill chat-replay

You’ll need Node.js, an internet connection, and FFmpeg for the final render.

If you’ve recorded a demo of a chat-based product, which part took the most work: getting a good session, keeping private information out of frame, or editing the pacing?
