It goed to show how negative HN is

Built an HTML wiki based on ideas from: The Unreasonable Effectiveness of HTML (@trq212)

Which way do they face?

- this is version 2 - you can now chat with the knowledge base - you can browse/view the wiki's - there's a nice graph/diagram

I built this for a security KB with a limited number of sources... But creating the Wiki's was fully automated, and it's easy to add/edit them with AI or manually.

On what topics would you like to see a Wiki LLM + knowledge base?

not open source, and early days yet... it's hosted online and not locally.

will work on a version 2 now.

I built a system to create a Wiki LLM (see tweets from Karpathy). Here's a public view of the results.

This is just based on 4 PDFs related to security (NIST CSF, security by design). It works on any input given (via PDF, web pages, etc.).

I implemented Live Chat, it works nicely. I didn't use my knowledge base for it yet... If I do it slows the whole thing down. So now it's just a limited prompt.

I built a "Both sides AI" inspired by Karpathy (https://x.com/karpathy/status/2037921699824607591).

- Will AI help the global economy? - Is Messi the best footballer ever? - Will we have AGI by 2030?

This tool does 3 passes of analysis for both sides of the argument.

- multiple models at once - rich content - retrieve web pages (for additional chat context)

You mean, how much would this cost for Enterprise?

It can be competitive, it's basically just the base model cost plus some markup.

Try AI chat with Rich Output (maps, locations, follow up questions, check lists, etc.)

Get rich content (output) instead of just text output in AI chat.

I built an AI chat that shows helpful Rich Content along with the typical chat.

It supports the following: - Gemini Flash - Gemini Flas lite - Grok 4.1

More models to come!

What other Rich Content types should I add?

Now at version 4... I've added some more features to my analysis of "Is my job safe from AI?"

- Treepmap of all occupations - Guage of risk per occupation - Sharing options - AI analysis from 3 scenarios - AI analysis from first, second & third order impact - Data from BLS

Each occupation gets a 1–10 risk score. You can search by job title or browse by category. There's also an interactive treemap where cell size = employment count and color = risk level, which makes it easy to see where the exposure is concentrated by volume.

The part I found most interesting to think through: I didn't want to pretend there's one answer, so I built three scenarios: pessimistic (AI displaces without replacement), moderate (net-stable, winners and losers), and optimistic (AI expands economic activity faster than it destroys roles). The treemap switches between all three.

Inspired by Andrej Karpathy's US Job Market Visualizer. Built on top of 99helpers.com, my AI customer support tool — the job risk checker is a free standalone tool.

Is my job safe from AI?

Inspired by Karpathy, I analyzed jobs to determine whether they're at risk from AI.

The interesting part:

I used 3 different scenarios:

Scenario 1 — AI Eliminates Jobs AI takes jobs; few replacements created

Scenario 2 — AI Transforms Jobs Some jobs lost; new ones created

Scenario 3 — AI Creates Opportunity AI generates new demand and job types

And I added first, second & third order effects: First, Second & Third Order Effects How AI disruption cascades through this occupation, the broader industry, and society at large.
