Software Engineer | Building — Create polished product demos from any web app (URL + prompt)

[Yves @YvesDC0]

Been building the Castfy landing page + waitlist with @le_con82546

Simple, clean, and focused on the core value: URL + prompt → polished product demo video.

Still early — iterating every day.

What do you think of the direction so far? Any feedback welcome 👇

@ihirwart Welcome bruh

SimilarWeb just showed Castfy got 238 visitors from May to June… and I haven’t even set up analytics yet 😂

@AdityaShips looks like I’ll be paying @getsleekio soon 👀

Still building every day.

Crazy how early traction feels when you’re solo.

Just finished the Castfy Playground 🎉

You can now test the tool directly: paste any web URL + prompt, and see the AI generate a polished product demo video in real time.

For now it would be “bring your own AI API key” (you keep full control and no extra cost from me).

Should I open it for early testing?

Reply with Yes / No / or any feedback 👇

Before Castfy: 45 minutes of manual recording + editing a simple Notion budget table demo.

After Castfy: URL + prompt → AI handles navigation, data entry, cuts dead time, adds voice-over.

Here’s the result ↓

Which version would you rather send to customers?

Day 24 of building Castfy in public.

One small milestone I'm excited about:

Castfy can now handle login flows that require manual OTP verification.

It auto-fills the email, waits for the OTP, then continues on its own—navigating the app, completing tasks, and producing a polished demo video.

In today's test, it created and filled a budget table in Notion.

Sensitive information is automatically masked in the exported video.

The goal is simple:
Give Castfy a URL + prompt, and let AI create the demo.
If this saved you hours of recording and editing, would you use it?

@CryoberryWeb Appreciate it!

That's the vision, URL + prompt → polished product demo with minimal manual work.

[Yves @YvesDC0]

@CryoberryWeb Thanks! That's what I'm aiming for—less time editing and more time sharing polished demos.

Day 23 of building Castfy.

Just shipped audio syncing for AI voice-overs.

Now the narration lines up perfectly with on-screen actions, making demos feel much more natural and professional.

MCP records the flow, AI automatically cuts dead time, and the voice-over stays in sync.

Still building every day.

Would AI voice-overs in your product demos be useful?

Yes/No—or share your thoughts 👇

Still waiting for this mn. and i have already joind on https://t.co/wrMhMJ0jeH

[Yves @YvesDC0]

@le_con82546 100% that's what we are building

[Yves @YvesDC0]

@le_con82546 We're launching soon

@le_con82546 Thanks

Day #22 of building Castfy.

Just shipped auto-cut for dead time in recorded videos.

The AI automatically removes loading screens, waiting time, and awkward pauses—so demos feel faster, tighter, and more engaging.

MCP handles the tool selection + recording. Then AI cleans up the final video automatically.

Building in public every day.

What's the most annoying part of recording demo videos for you?
