Hi everyone!

I'm Julien, the founder of Chronos Lab, and I wanted to share what we've been building and get your feedback.

Like many founders and developers, I rely on AI every day.
But I kept running into the same problem: every important project eventually outgrew a single chat.

I found myself constantly re-explaining:

Most people are learning more than ever and retaining less than ever. AI makes information frictionless. You can ask anything, get a clear explanation instantly, move on. It feels like learning. But there's a difference between understanding something in the moment and actually building knowledge that compounds and that difference is showing up everywhere. Developers who can prompt but can't debug. Students who can summarise but can't reason. Professionals who consume endlessly but feel no more capable. The problem isn't access to information. It's that nobody taught us how to structure it. I am currently building an e-learning platform in the AI era, so I went looking for what the research actually says about this. It's older than AI and more precise than most people expect. Every complex field has an underlying structure a directed graph where concepts have prerequisites. Skip a node and the downstream idea has nowhere to land. Your brain isn't being slow; the foundation just isn't there. John Sweller's Cognitive Load Theory explains the mechanism: working memory is genuinely small, and when you encounter a high-complexity idea without the right scaffolding in place, the load exceeds capacity. It's not a motivation problem. It's a sequencing problem. Jerome Bruner argued you don't need to master something in one pass you introduce it simply, let it settle, then return deeper. Benjamin Bloom's mastery research adds that you shouldn't advance until the current rung is solid, because higher-order thinking is unprocesseable without it. Robert Bjork showed that spacing and revisiting feel harder but compound far better than cramming. What this all points to: in a world where AI handles recall and explanation on demand, the scarce thing is structured understanding. The kind that's yours. The kind you can reason from, not just retrieve.

The product I am working on is built around this idea that the structure of a subject should drive how you learn it, not the availability of content. The curriculum follows the knowledge graph. The experience adapts to you. The goal is understanding that actually sticks. If you're trying to learn something deeply right now and feel like you're spinning you probably are. Not because the material is too hard, but because nobody handed you the map.

Few days into launch and the pattern's clear ATS Integration (Greenhouse + Lever) is the feature people keep coming back to. Makes sense: nobody wants a great screening tool that still means exporting CSVs and living in two systems at once.

Alongside that: AI resume screening that actually reads every resume, clean hiring reports, dual-currency pricing, and a live dashboard tying it all together.

Also shoutout to everyone pushing back on default scoring rubrics (you know who you are ). That's now genuinely on our radar. This is exactly the kind of thing that makes launching here worth it.

Curious to hear: if you're dealing with ATS chaos right now, what's the one part of that mess you'd fix first if you could wave a wand? Screening speed? Ranking accuracy? Something else entirely?

We ve all been there: planning a trip with friends starts with excitement and quickly turns into a chaotic mess of endless group chats filled with 100+ photos, unanswered questions, lost links, and budget disagreements.

That is why I built HolidayHub Elite a real-time, collaborative web app designed to centralize everything in one beautiful place, from trip planning and photo sharing to easy budget splitters.

(Please note: the application is currently fully in French, making it the perfect tool for francophone friend groups planning their next getaway!)

I've been building this solo and wanted to get some honest eyes on it before I get too attached to my own assumptions.

The problem I kept running into: when a subscription payment fails, almost every tool sends the same generic "your payment failed, please update your card" email. But the reason it failed is usually very different an expired or lost card, insufficient funds, or a bank 3-D Secure/SCA verification challenge. Telling someone to "update your card" when their bank just needs them to confirm the charge is not only useless, it makes the whole thing read as impersonal and a bit spammy. Industry-wide, a meaningful chunk of subscription churn is just failed payments that never get recovered, and a lot of that is these avoidable mismatches.

Namaste Traders,

Hum ek AI-powered trading platform VedKuber bana rahe hain jo traders ko market analysis, portfolio tracking, paper trading aur smart trading tools ek hi jagah provide karta hai.

Abhi hum beta phase mein hain aur kuch active traders ko invite kar rahe hain jo platform ko use karke apna genuine feedback de sakein.

After months of building, testing, refining, and overcoming more than a few unexpected challenges, we're finally here.

Kognis is ready.

Fully tested
Approved by Apple
Approved for Android

We were all set to launch... and then life had other plans. I ended up having my appendix removed just days before release.

Hi Product Hunt Pioneers,

I'm a B&B manager who accidentally built a SaaS product. Let me explain.

I run Filiato, a small education brand for digital entrepreneurs. Instead of selling e-books and templates, I made the library free.

Some resources even come with rights to modify and resell them.

People ask me why.
