Going by the example videos, this is nothing like I'd expect a whiteboard video to look like. It fills the slides in erratically, even text. No human does that. It's distracting more than anything. If a human teacher wants to show cause-and-effect, they'll draw the cause, then an arrow, then the effect to emphasize what they're saying. Your videos resemble printing more than drawing.
It seems really strange that you wouldn't farm this kind of thing out to a non-AI function that animates the text properly into the space given using parameters that the AI generated. I mean it's impressive that it does work at all, let alone as well as it does, but are we also going to get an AI to do all the video encoding as well?
Wow, I was skeptical at first, but the result was pretty awesome!
Congrats! Cool product.
Feedback: I tried making a product explainer video for a tree planting rover I’m working on. The rover looked different in every scene. I can imagine this kind of consistency may be more difficult to get right. Maybe if I had uploaded a photo of how the rover looks it may have helped. In one scene the rover looks like an actual rover, in the other it looks like a humanoid robot.
Love this idea! The Whiteboard Gym explainer video seemed really text-heavy (although I did learn enough to guess that that's because text likely beat drawing/adding an image for these abstract concepts for the GRPO agent). I found Shraman's personal story video much more engaging! https://x.com/ShramanKar/status/1955404430943326239
Love it. The tone is just right. A couple of suggestions:
Have you tried a "filled line" approach, rather than "outlined" strokes? Might feel more like individual marker strokes.
I made a demo video on the free tier and it did a great job explaining acoustic delay lines in an accessible fashion, after feeding it a catalog PDF with an overview of the historical artefact and photography of an example unit. Unfortunately the service invented its own idea of what the artefact looked like. Could you offer a storyboard view and let users erase the incorrect parts and sketch their own shapes? Or split the drawing up into logical elements and the user could redraw them as needed, which would then be reused where that element is used in other frames?
I love the concept but the implementation in the demo seem not good enough to me.
I think the black and white demo is quite ugly...
1) Explainer videos are not in black and white
2) the images are not drawn live usually.
3) text being drawn on the go is just a fake animation. In reality most explainer videos show short meaningful sentence appearing all at once so the user has more time for reading me.
I'm also not the biggest fan of the white-on-black style, but there is definitely precedent (at least in science-youtube-space) for explainer videos "drawn live" [1-4]
Feedback on the text: I find the way that the text generates randomly across the line very distracting because I (and I think most people) read from left to right. Having letters appear randomly is much more difficult to follow.
Are there options to have the text appear differently?
I have used AI in the past to learn a topic but by creating a GUI with input sliders and output that I can see how things change when I change parameters, this could work here where people can basically ask "what if x happens" and see the result which also makes them feel in control of the learning
Chalkboards are white on black. You basically have chalkboards or whiteboards to draw from. Not sure either is landing in the Louvre. Both have their aesthetic uses. I'd imagine chalkboards for academic topics, whiteboards for business, but different ages and cultures will feel differently.
This is neat but I wasn’t able to get it to work (server overloaded is what the browser app said)
I’d also recommend registering a custom domain in Supabase so the Google SSO shows the golpo domain - which is a small, but professional-signaling affordance
The generated graphic in the linked demo for "Training materials that captivate" is a sketch of someone looking forlorn while holding a piece of paper. Is there a way to do in-line edits to the generated result to polish out things like this?
I'm sure someone else has mentioned this but your video on the main page correctly has GRPO the first time it's introduced but then every time you mention it after that -- you've swapped it to GPRO.
This is really interesting, definitely going to give it a try! Seems fun but are you seeing people actually needing to make lots of videos like this? What's your vision - how does this become really big?
The way text is appears is so weird, is like rendering a by plotting each letter aschronously. I wonder how it compares to auto generated power point presentations. I suspect it might be worse
Not only the giants. They will face significant threat from open source too[1]. But they just need to carve their own user base and be profitable in that space.
1. For example, I have built http://gitpodcast.com which can be run for free. Can also be self hosted using free tier of gemini and azure speech.
I'll try the 1 free generation soon, but the way the text appears randomly in that landing page demo video is really weird. I keep loosing track of where I'm reading too as the audio sometimes is not perfectly synced. The sync is not that bad however, but it could be better.
I created a video on the free tier, the shareable link didn't work (404), I upgraded to be able to download it, and it seems to have disappeared? It says "Still generating" in my Library.
The video UUID starts with "f5fbd6c7", hopefully that's sufficient to identify me!
Sorry about that! I found your video. Should I link it here or DM it to you (can you do DM in Hacker News?) ? You could also email me at [email protected], and I can send it there
Popup window with "Load Failed" after it had some progress on the bar past 40% or so. Shows up in the library, but won't play. I just deleted it for now.
One of the founders here! No it's not. The max video length is up to 2 min, which is also the case in any non-free tier. We just include a 15-second option for that tier (because people it need for things like FB ads)
Given that the next tier up is "Create longer/more detailed video (up to 4 min long)", I'd guess you are right.
Seems like this is pretty useless unless you pay 200$ per month. Which may be a reasonable number for the clearly commercial / enterprise use case, but I'm just not certain what you can do wtih the lower tiers.
Can confirm, it creates slides though, not whiteboard animations. Although the slides are in color and have graphs, clipart, etc. (but they are static and the whiteboard drawing is cooler!)
It created an 8 minute video explaining my Logo-based coding language using 50 sources and it was free.
My suggestion would be to re-think the demo videos. I have only watched most of the way into the "function pointers in C" example. If I didn't already know C well, I would not be able to follow that. The technical diagrams don't stay on the screen long enough for new learners to process the information. These videos probably look fantastic to the person who wrote the document it summarizes, but to a newbie the information is fleeting and hard to follow. The machine doesn't understand that the screen shouldn't be completely wiped all the time while it follows the narrative. Some visuals should be static for paragraphs, or stay visible while detail marked up around it. For a true master of the art, see 3blue1brown.
I agree. Rather than (what I assume is) E2E text -> video/audio output, it seems like training a model on how to utilize the community fork of manim which 3blue1brown uses for videos would produce a better result.
that seems like excellent product market fit as the AI generated explainer videos won't even need to be correct, and the more incorrect they are the better the troll
Its not that simple, but it would be straight forward to duplicate the outputs of this with a simple LLM + ffmpeg workflow. They did mention a custom model on the landing page, and if they've trained one then you would be spending much more money on each output than they are. Because without a fine-tuned model there would be a lot of inference done for QA and refinement of each prompt | clip | frame .
no, not really. I think they are massively over-valued but in the tech world... what else is new? I view those tools as mostly a convenience. They are integrating things into nice easy packages to use. That's the value.
With this... eh. Most people don't need to make more than one or two explainer videos, so are they going to take on a new monthly fee for that? And then there are power users who do it all the time, but almost surely have their own workflow put together that is customized to exactly what they want.
At any point, one of the big players could introduce this as a feature for their main product.
In the Khan academy videos I remember watching, an instructor would actually write on a tablet; you'd see each letter get hand-written one by one in order. Is there no way to get it to do that? What the AI is doing instead is building-up the strokes of every character on the line of text all at once, which looks completely unnatural. The awkwardness is compounded by the fact that the letters are outlined, so it takes even more steps to create them.
In addition, the line-art style of the illustrations looks like that same cartoonish-AI-slop style I see everywhere now. I just can't take it seriously.
If this tool is widely deployed it's just going to get used to spread more misinformation. I'm sure it will be great for bad actors and spammers to have yet another tool in their toolbox to spread whatever weird content or messages they want. But for the rest of us, that means search engines and YouTube and other places will be filled with a million AI-generated half-baked inferior copies of Khan Academy. It's already hard enough to find good educational resources online if you don't know where to look, and this will only make the problem worse.
You'll just have to forgive me if I'm not really excited about this tool.
I made it 8 seconds into the "function pointers in C" video and immediately stopped. It went too fast to read the code examples and diagrams. (second "slide" appears for 1 second.. and what is that array it is showing?) If you go back and look at the code (a three line swap function) - it's messed up. No opening bracket and where is the closing bracket? It is "swaps first and last", but hard-coded to only length 3 arrays?
I'm sure AI could help make good animations like this, but this looks like slop.
I feel like this is another case of throwing AI in a non-AI-required problem. Khan Academy itself just hired people to make its videos at a very reasonable wage. Why would you need to add AI into the equation? If you wanted to, you could build a platform of basic video / whiteboard content creators at a very reasonable price point.
Edit: I've used. It's amazing. I'm going to be using this a lot.
Congrats! Cool product.

Signed up and waiting on a video :)

> The Al needs to figure out not just what to draw, but precisely when to draw it
;)
But, white on black is really ugly. Even black on white or a simple inversion would be an improvement.
I think it could benefit from the ability to pause and see the transcript, and make edits before the video is generated.
I asked it about pointers in Rust. The transcript and images were great, very approachable!
"Do not let your computer sleep" -> is this using GPU on my machine or something?
What I always wanted to do was to teach what I know but I lack the time commitment to get it out. This might be a way…
Note: Your paywall for downloading the video is easily bypassed by Inspect Element :)
My main concern for you is that y'all will get Sherlocked by OpenAI/Anthropic/Google.
1. For example, I have built http://gitpodcast.com which can be run for free. Can also be self hosted using free tier of gemini and azure speech.
I would love to add a link to my product docs, upload some images and have it generate an onboarding video of the platform.
I’m mostly curious how it fairs with more complex topics and doing actually informative (rather than just “plain background”) illustrations.
Like a video explaining transformer attention in LLMs, to stay on the AI topic?

If I may ask - how do you generate your audio?
What does one do if they want to make a 5-10 minute explainer if the maximum length is 2 minutes?

...also the name is a bit weird. It reminds me of "Gulpo, the fish who eats concepts" from that classic SMBC cartoon. (https://www.smbc-comics.com/comic/2010-12-15)
Straight vector paths?
I'm sure AI could help make good animations like this, but this looks like slop.
