- Phone number sign-up means instant delete. Absolute no-go.by blazarquasar
- Sorry about that. We wanted to implement more social features on the app to let users learn with their friends which we figured letting users find friends from their contacts/phone number. Understand that isn't for everyone and we might make some changes to make those social features opt-out.by zackashen
- That logo for „introduction to topology“ feels incredibly off. The Möbius Loop doesn’t connect to itself in the back
- Yea we generate the course icons with a quick image generation model so total accuracy in representations is not guaranteed. But the actual courses themselves use research to construct the outlines and videos. Feel free to email us (founders@trykeet.com) if you end up taking that course and have any other thoughts.by zackashen
- The demo videos look pretty engaging. Is the main aim to create bite sized content or longer videos as well ?by ashu1461
- Thanks! We might end up doing longer videos, but we just found that there was a happy-medium for our attention span with the videos and making them bite sized kept us the most engaged. However, this decision was made before we made some significant improvements to our video generation workflow and so we definitely have been talking about whether longer videos could make more sense now. Our goal is to just deliver the content in whatever format helps people learn and stay engaged the best, so if that ends up being longer videos or some variety of short-form and long form than that works for us.by zackashen
- Building educational content to teach users how to use your software is extremely challenging. Would be interesting to position this against startups.
Most of those subject matters - to me - are fun to chat with LLMs with to learn (Gemini hooked to web research works nicely).
But the expectations of easy-to-use software is rising. A solution to this problem would be extremely valuable.
Sorry, this comment feels a bit like https://www.youtube.com/shorts/61ZqBW30LLA but just rambling
by kerryritter - Haha, no that makes sense. I think we've seen a few other people building toward what you are describing, but it definitely would be interesting to see if people end up generating courses in this direction. I think there was a company in a recent YC batch called Clicky (https://www.heyclicky.com/) that built something adjacent to what you are describing (https://x.com/FarzaTV/status/2041314633978659092).by zackashen
- Interesting!
I get blocked on the phone number screen on sign up.
This has two issues:
1) It seems to require a US phone number (555-555-5555)? 2) Ideally I don't want to share my phone number at all. It says it is for finding friends, but I think many people don't want to share their phone number this lightly.
The app also tries to get access to my contact list - not ideal for just trying something out :)
by jaldert - Thanks! We are currently working on enabling international sign ups. Regarding the contact list and sharing your phone number, we wanted to make the app so you could interact with your friends courses as well. Sharing your contacts is also skippable. If it seems like users aren't using any features that would make interacting with users helpful, then we'll definitely remove requesting phone numbers in onboarding.by zackashen
- Are the courses meant only for personal consumption or can/will they be offered to other people? (for ex I have a Linux/DevOps training & assessment platform)by fduran
- Courses are publicly available. When you generate a course anyone on the app can enroll in it.by zackashen
- Super cool!
Would you mind giving more insight into how you make the videos (sourcing clips or generating them for Remotion videos, agentic?, and how you handle rendering issues and QA for the Manim videos) and costs?
by iamcoder18 - Both workflows follow the same broad pattern. First, break the video into a set of scenes, then plan the scene, write the code, render it, and iteratively refine the result.
For Remotion, the AI determines what resources the scene will need, whether that be images, generated assets, or prebuilt visual components. This part doesn't happen in Manim because its more for math based visualizations.
Re costs, both workflows have a series of presets that make the implementation less expensive and more consistent. The reduction in price for the Terra model series has been particularly helpful for us.
by zackashen - Isn't video generation expensive? Are you letting/making users generate series of videos without any plan? I think content depth and breadth would be good to check pre-generation at a minimum.
- We are generating the videos using Remotion via React so its not as expensive as using a AI video model like Veo. There are three places where you can customize the course before you generate:
1) The initial prompt where you type what you want to learn
2) There are a couple universal follow up questions that ask the depth and breadth you want to learn at
3) There are then some course specific intent questions we ask that ask content specific questions. For example if you type "History of NYC" we might ask "What time period do you want to focus on?"
by zackashen - The QR code that shows on hovering the "Download" button is very cool! Kudos to the person who came up with that.by rubymamis
- Thanks! I can't take credit though I first saw it on the landing page for Halo (halohabits.app).by zackashen
- Very cool, congrats on the launch. Are there any licensing issues with customers releasing generated courses with copyleft or public domain licensing?by toomuchtodo
- Thanks! Right now, any course you generate is freely accessible to anyone on the app. Sharing the course requires other users to sign up for Keet. In the future, we could build in some features to allow users to extract the course outlines and videos, but we haven't seen that requested so we don't have any licensing in place for that.by zackashen
- I'm excited to try this.
I installed it on an iPad Air (M2). On launch, I am given two options:
- Get started (primary CTA). Tapping this takes me to a blank screen.
- Sign in (secondary CTA). Tapping this and choosing 'Continue with email' gives me a login screen. I tried entering my email and choosing a password but it says "Couldn't find your account"
- Really sorry about that. We are looking into what happened. Do you mind sending us an email at founders@trykeet.com, so we can help you get signed up.by zackashen
- I tested it and the videos look great, congrats on that.
That said, I’m struggling to see a thriving business here, for two reasons. First, the moat looks shallow. Anthropic and OpenAI are already building in this space, and it’s hard to see what stops them from shipping something better and cheaper fully integrated with their ecosystem soon.
Second, I don’t think customer behavior around AI-generated content (and especially in your case) is settled yet and this affects many similar business across the board. The videos are good, but perception is a separate question from quality. If your buyers are content creators, schools, and e-learning platforms, they’re ultimately selling to their own customers, and they’ll need confidence that the content won’t read as cheap, low-effort or similar to everyone else.
This might be the golden era for starting a company, but building a wrapper around an LLM is risky unless something outside the software holds it up (proprietary data, distribution, a regulated position, real switching costs or any external component). Otherwise the model providers or a well-funded copycat can rebuild it.
Wishing you guys good luck! All the best!
