@YvesDC0 This is the future of making demos in short time

[le con @le_con82546]

That's huge progress

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?

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?

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 👇

[le con @le_con82546]

@YvesDC0 Yeah, AI voice would better when i want to move faster. But it would be evn better if I would also add own voice or music too

Phone-recorded this while testing Castfy.

Gave it a GitHub URL + prompt → watch the AI automatically navigate and fill login details in real time (stopped before submitting for safety).

No manual screen recording. No editing. Just URL + prompt = realistic demo flow.

This is exactly what Castfy does: turns any web app into a polished product demo video in minutes.
