Getting Started
What is CustomCast?
CustomCast turns any YouTube video into a conversation. Instead of just watching, you can talk to your video out loud — ask questions, get instant explanations, and have topics summarized for you in real time. It's like having a brilliant, patient companion sitting next to you who has already watched everything and is happy to break it down however you like.
Do I need to download or install anything?
Nope. CustomCast runs right in your web browser — on your computer, phone, or even your smart TV's browser. There's nothing to install, no app store, and no setup headaches. Just sign in and start.
How do I get started?
It takes about ten seconds. Sign in, paste a YouTube link (or pick one of our suggested videos), and start talking. The moment you ask your first question, CustomCast is right there with you — no menus to dig through, no manuals to read.
Can I try it before I pay?
Absolutely. Every new account starts with a 3-day free trial so you can experience the magic for yourself. You can also try our live demo right on the home page in seconds. We're confident that once you talk to a video, you'll never want to go back to just watching.
Using CustomCast
How do I actually "talk" to a video?
Just speak naturally — the same way you'd ask a friend. You can interrupt at any point to ask "wait, what does that mean?", request a quick recap, or dig deeper into something that caught your interest. It's completely hands-free, so you can keep watching, taking notes, or relaxing while you learn.
Can I type instead of talking?
Yes! If you're in a quiet room, on a noisy train, or just prefer typing, you can chat by text instead of using your voice. You get the same smart answers either way — use whatever feels right in the moment.
What kinds of things can I ask?
Anything you'd want to know about what you're watching. Popular favorites include "Summarize this video," "Explain the main concept," "Just give me the answer," and "Explain it like I'm five." You can ask follow-ups, request real-world examples, or have a complicated idea broken down step by step until it finally clicks.
What are Custom YouTube Feeds?
Custom Feeds let you build your own curated lineup of videos — your favorite channels, a study playlist, or a hand-picked set of safe content for your kids. It's your space, organized your way, so the good stuff is always one tap away and the noise stays out.
Can I use CustomCast on my TV?
Yes — and it's one of the best ways to use it. Open CustomCast in your smart TV's browser to watch on the big screen, and use your phone as the microphone so you can talk to your video from the couch. Movie night just became interactive.
Is it safe for kids? What's the Parental Sandbox?
The Parental Sandbox creates a safe, guardrailed space where children talk directly with a patient, supportive voice tutor instead of wandering the open internet. You stay in control of what they can watch, and they get a calm, encouraging learning companion that meets them at their level. It's screen time you can actually feel good about.
Plans, Credits & Billing
How much does CustomCast cost?
CustomCast is refreshingly simple: start with a 3-day free trial, then a one-time $20 unlock. That's it — no monthly subscription and no surprise renewals creeping onto your card every month. Pay once, and it's yours.
What are credits and how long do they last?
Credits are simply your minutes of conversation time. Your unlock includes 100 credits — about 100 minutes of talking with your videos (roughly one credit per minute). Watching the video itself is always free; credits are only used while you're actively chatting with your companion.
Is this a monthly subscription?
No. We deliberately built CustomCast around a one-time unlock instead of a subscription, because nobody likes forgotten charges piling up month after month. You pay once and you're in.
What happens when my free trial ends?
After your 3-day trial, your one-time $20 unlock activates so you can keep talking to your videos without interruption. If CustomCast isn't for you, simply cancel before the trial ends and you won't be charged anything at all.
Can I cancel during the trial?
Yes — and it's completely painless. Cancel any time during your 3-day trial and you pay nothing. No hoops, no guilt trips. We'd rather earn your trust than trap you.
Do you accept promo codes?
We do! If you have a promo code, just enter it at checkout and your discount will be applied automatically. Keep an eye out — we love rewarding our early supporters.
