Hey - I've been playing with LLMs since GPT-2 and recently experimented with fully generative UIs where the HTML/Canvas are generated just-in-time.

Every post on the feed( on slop/duck/storytime) you see is streamed and generated just-in-time with HTML and into a Canvas with Gemini 3 Flash.

Comments and DMs are bidirectionally linked with a Cloudflare Workers Durable Object which is why they feel so fast. Every generated post is saved into a DO SQLite which is then served into the "Following" feed so it can be served quicker.

This was inspired by Wikitok, a VSCode Extension I made around brainrot, and another fully generative UI site I made.

Sounds like WikTok (2023, https://news.ycombinator.com/item?id=42936723) or WikiTok (early 2025, https://news.ycombinator.com/item?id=42936723).

"This was inspired by Wikitok, a VSCode Extension I made around brainrot, and another fully generative UI site I made."

I saw that but got the submitter and commenter names mixed up, so I didn't realize it was the same person.
aizk•9h ago

mellosouls•7h ago
I also thought immediately of WikiTok and was confused by this exchange and the grammar in the quote here; I thought they were claiming to have made a VSCode extension called Wikitok. I understand now!

for clarification :)

personjerry•10h ago
The animations + audio are great. I feel like these meaningfully differentiate from some other similar projects. There's a lot of potential here.
furyofantares•10h ago
Reading it with sound off is really hard because of the way the words come up one at a time, rather than the whole sentence at once.

emsign•10h ago
Nice tech demo but in practice utterly annoying and without purpose. I mean don't you think enshitifying Wiki knowledge kind of beats the purpose of acquiring knowledge?
odie5533•9h ago
It's a proof of concept to pave the way. I could see benefit in having series which deep dive into material. This felt too shallow to me.
Edmond•9h ago
Work related versions of this, expense report:

https://youtu.be/h0Bg-lqNlkU

In general Just-In-Time app generation is a bad idea. The right approach is to create human-in-loop tools that a bot would recognize and invoke as needed, of course the human-in-loop tool would itself be AI generated.

Example of human-in-loop tool in use:

Honestly, pretty cool.
kerisi•9h ago
you can use LTX to generate the videos, this video took 15s on a 4090

nice did you make this just for the comment? haha
kerisi•4h ago
yep haha
gregjw•4h ago
we live in an era of frictionless slop creation. yay.
vedmakk•9h ago
This is really cool. I'm interested in the GenUI part. Is the web app itself static and the stories are generated on-demand?

Do you give gemini some UI components/templates to build with or is it just prompting to get consistent results across multiple stories?

pests•8h ago
Google AI Studio has a Gallery[0] with some similar apps. It's an editor so you can view the code, they are usually react apps with gemini integration via genai package. Like this one here[1] is similar. It generates interesting stories to share about a route you are driving / walking / biking along. This is one of the pre-made examples I believe, I didn't make it or anything. Just to show some how some of this might work.

sdan•7h ago
Yes I have base css/js that I inject on top of whatever codegen gemini 3 comes back with -- It runs via ai-sdk so the specific function is streamObject which is prompted to generate inner HTML elements

sdan•7h ago
thanks
aizk•9h ago
Hi there, creator of Wikitok here! Very happy to hear that my random little project inspired you :) The attention to detail in the UI is good - I'm so over every default AI generated UI being rounded corners, centered divs, blue and purple gradients, etc. Nice work.
sdan•7h ago
Thanks! Half of the work here was getting gemini to generate reasonable canvas animations within the window. I'm still experimenting which "style" I should keep/add
cons0le•8h ago
This is amazing! I think this could actually catch on!

Plz give an easy way to follow some tags so it's not showing me football stuff. If it was just topics I was interested in, I could scroll this for hours.

sdan•7h ago
Huge- good to hear will see if I can add a way to type in what you want or to go dig further into just certain hashtags.
bstsb•8h ago
wow, my attention span is terrible - the first time i tried watching a generated video, i instinctively held the right side of the screen to speed it up to 2x…

is there scope for allowing users to search for / ask about specific topics? although then you do have to think about security issues with prompt injection

cornonthecobra•7h ago
The caption highlight timing is very inaccurate. It looks like it just steps through each word on a fixed timer, rather than using timing information from the TTS engine?
sdan•7h ago
Yes just fixed timer, and using browser TTS nothing fancy here on purpose - when I did some research on tiktok videos generally simpler/worse quality seemed to be better XD

oceansky•4h ago

jaredsohn•4h ago
Next step is allow viewing TikTok like wikipedia. Take a bunch of popular tiktok posts, use an LLM to describe what's happening via text/screenshots (with references to memes, etc), and link them to other relevant tiktoks.

Some meme sites might be somewhat similar to this.

NoteyComplexity•1h ago
Instead of LLM and just like Wikipedia, there should be users to submit the descriptions of the videos, and see people fighting for getting the most “correct” description.

It will be hilarious to see what people will come up with when they see brain rot content.

maxbond•4h ago
Having a generated voice tell me about some historical massacre in a chipper tone with a generated infographic and set to TikTok music was. Especially dystopian.

As an experience I found it nauseating and am never doing it again, but as an art piece I give it high marks. Good job.

gregjw•4h ago
Indeed.
tylervigen•4h ago
Hilarious. The one AI voice is a little too grating for me, but with a little variation I might actually scroll it for a while.
Imustaskforhelp•4h ago
Yea I didn't like the voice as well, it felt very coarse to me and not very enjoyable

To be really honest, I still occasionally browse shorts sometimes because of some youtubers/niche content (there is this really good etymology shorts guy and a fun fact guy I watch usually)

So like the other day I was asking fun fact about niche legal laws just out of curiosity if anyone of them might be interesting/genuinely helpful to me lol to chatgpt about different countries

There were lot of niche things but one which I found interesting was that its possible in finland and other norweigian countries to browse even private land / private forests etc. and finland even has a digital right to internet

> Finland was the first country in the world to make access to high-speed internet a legal right, establishing this policy in July 2010. The law requires all service providers to offer a minimum internet speed of one megabit per second to every household, with a goal of providing access to 100 megabits per second by 2015. PBS edri.org (from Duckduckgo AI)

sdan•3h ago
A few months ago I made a (theoretically) infinitely learning geo-guessing model that updated the policy with each user guess: https://geospot.sdan.io/

Hoping to implement a simple RL loop here and optimize whats generated by the LLM to create the perfect slop machine :)

grugagag•3h ago
Good. However, on a smaller phone such as Iphone SE the viewport gets cropped all around and I don’t see around 20% of the content.
sdan•3h ago
Note there's a rate limit on generated content for the time being, why you're unable to see any new content on the rest of the feeds. LLMs are expensive!
mappum•3h ago
Missed an opportunity to name it WikWok or Tikipedia.
raleighm•2h ago

sdan•2h ago
great suggestion ! i might change it to wikwok, so good
asciii•2h ago
This is so awesome - i wish I could modify that annoying voice :)
alexpadula•2h ago
It’s a cool idea but the content needs to be more useful imo.
sdan•2h ago
how could i make it more useful? different formats? would you want to keep you engaged for longer? entertained for longer?
garyfirestorm•2h ago
Relevant content - what is relevant to me may not be relevant to you.

anotherpaul•1h ago
Oh I hate it it's so brain rotty. Well done. Well done indeed.
omegabravo•18m ago
I was confused why someone would possibly configure the voice to be quiet and raspy.

Seems like there's an issue with Firefox that was causing it. Chrome voice sounds "normal" - like TikTok.
