Introduce TutDub — upload once, speak to the world

Every tutorial creator knows this comment section.

You spend a weekend recording a lesson you're genuinely proud of. You edit, export, hit publish. And within a day or two the requests start rolling in: "Any chance of a Spanish version?" "Please do this in German." "Would buy a course in Japanese."

Each request is flattering. Each one is also completely unreasonable, because re-recording a forty-minute screencast in five languages isn't a task, it's a second job. Nobody does it. That's why most great tutorials stay stuck in one language forever.

We built TutDub because we were tired of the answer being "sorry, no."

Upload once. Speak to the world.

So what does it actually do?

TutDub is an AI dubbing tool made for screencast tutorials specifically. Coding walkthroughs, software demos, how-to lessons. The stuff people publish on YouTube, Udemy, Teachable, and Skillshare.

On your end the process is embarrassingly simple: you pick a video and upload it. Then TutDub gets to work.

1. It transcribes everything you said.
2. It cleans the transcript, cutting out the "um"s, "uh"s and "you know"s. (Fair warning: the first time you see the count, it stings a little.)
3. It clones your voice, so the result sounds like an actual person. Like you, ideally.
4. It dubs the translated script into whichever languages you chose, in that cloned voice.
5. It exports a finished, publish-ready video for each one.

You get back a set of localized tutorials that still sound like the person who recorded the original. Same pacing, same personality, different words.

Fourteen languages, one voice

Right now TutDub speaks Chinese, English, Japanese, Korean, German, French, Spanish, Indonesian, Italian, Thai, Portuguese, Russian, Malay, and Vietnamese.

Think about what that means for a single upload. Your Python course suddenly exists for Latin America. Your Figma tutorial has a German edition. Your dev tooling walkthrough reaches the enormous Japanese community that most Western creators never touch. All of it narrated by the one voice your existing viewers already trust: yours.

No black box

If you're a technical creator, you've earned the right to be skeptical of AI products that won't say what's running inside them. Fair enough.

TutDub's speech and voice technology is built on open-source foundations, not a closed service we refuse to talk about. Your voice recording and your content are the raw material for all of this, and you deserve to know what happens to them. That transparency matters doubly for dev-ed creators, because many of you work with this exact stack yourselves.

Pricing that doesn't punish you for starting

TutDub works on credits, and the math is refreshingly boring: one credit dubs one minute of video. That's it. No processing fees, no "premium voice" upsells hiding in the checkout. Dub your ten-minute lesson into Spanish and it costs ten credits. Want German too? That's ten more, so twenty credits gets you both versions. Every language runs at the same flat rate, and you only pay for the versions you actually order.

You don't even need to pull out a card to see how it sounds: every new account starts with three welcome credits, enough to dub a few minutes and hear your own voice speak another language. From there you have two ways to buy: grab a credit pack in whatever size fits your current project, or pick a subscription if you know you'll be dubbing regularly.

The subscription is where regulars win. Credits cost less the more volume you commit to, your jobs jump ahead in a priority processing queue, and higher plans add features on top, like the adaptive timeline, which adjusts the pacing of each dubbed version so it fits its language naturally (available starting with Pro). Pay-as-you-go packs stay available for everyone else; nothing is locked behind a plan you don't want.

The choice roughly follows the people buying. A course creator with one or three lessons on Udemy or YouTube usually grabs a pack and is set for months. Dev-ed channels tend to pick TutDub because of the transparency, not despite it. And teams localizing client training at volume go straight to Business, because their libraries are bigger.

And if budget is tight at the beginning (we remember those days), there's a community deal built right in: tweet about TutDub and get 15 free credits on top, a bonus you can claim again every month. Creators telling other creators is honestly the best marketing we could ask for, so we'd rather pay for it in credits than in ad spend.

The short version

You already made the hard part: a good video. It deserves more than one audience.

Upload it once. TutDub cleans it up, keeps your voice, and sends it out in fourteen languages. No second takes required.

What's next

This post is the opening chapter of a short series on going multilingual, and the next few are already in the works.

Coming up this week: a step-by-step walkthrough of uploading your first video, a closer look at automatic filler removal (why those "um"s hurt more than you think), the full story of translating your video into 14 languages in your own voice, and a screen-recorded demo where you can watch an actual translation happen in real time.

After that we'll slow down and answer the questions we hear most from course creators: how voice cloning really works and why it's nothing to be nervous about, whether subtitles or dubbing grows your audience faster, and a behind-the-scenes tour of the open-source AI that powers all of it.

FAQ

1. What is TutDub?

   An AI dubbing tool for screencast tutorials. You upload one video, it removes the filler words, clones your voice, and translates the lesson into 14 languages, narrated in that cloned voice.

2. How many languages does TutDub support?

   Fourteen: Chinese, English, Japanese, Korean, German, French, Spanish, Indonesian, Italian, Thai, Portuguese, Russian, Malay, and Vietnamese.

3. Does TutDub put an AI avatar on my video?

   No, and that's deliberate. Tutorials live on the screen, not on a face. You get your original footage back with a new voice track, nothing pasted over it.

4. Will the dubbed video still sound like me?

   Yes. TutDub clones your real voice from the recording and uses it for every language, so it sounds like you rather than a generic narrator.

5. What happens to my "um"s and "uh"s?

   They get removed automatically during cleanup. Every localized version comes out tighter than the original recording, which regular viewers tend to notice and appreciate.

6. Which AI models does TutDub use?

   Transcription runs on NVIDIA Parakeet, an open-source speech recognition model, and the voice cloning uses Confucius4-TTS. Both are open source, which is exactly why we picked them.

7. Is there a free plan?

   Yes. Every new account gets three welcome credits, which is enough to dub your first minutes of video before paying anything. After that you buy credit packs in whatever size you need, or take a subscription if you dub regularly: cheaper per-minute rates, priority processing, and extra features like the adaptive timeline from Pro up.

8. How does the tweet-for-credits thing work?

   Tweet about TutDub and we'll add 15 bonus credits to your account. The bonus repeats every month, so a fresh tweet keeps topping you up. No spam tricks needed, just share your real experience.

9. Which platforms is it meant for?

   YouTube, Udemy, Teachable, and Skillshare are what we designed around, but the exported videos are standard files that work anywhere.

10. Do I need a good microphone or a studio?

    No. If viewers can understand your original recording, TutDub can work with it. Everything else happens in the cloud.
