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 vibe coding a small product around a buying problem I hate: two phones, forty tabs, every review says it depends.

WorthCop s bet is rude on purpose. You pick two phones and a stake (camera / battery / value / etc). It always calls a winner. Never both are great.

I m curious what other makers think:

1. Does forcing a winner feel useful, or does it make people trust the product less?

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.

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

Kognis is ready.

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

I noticed your link is bunched up at the start of the sentence in the screenshot. To make it more clickable and readable for the Product Hunt community, try this formatting:

I just launched a new tool on Free Document Maker (FDM AI) to solve a common frustration: Passport Size Image Resizer.

Most online tools are cluttered with ads or require software downloads. Our browser-native resizer provides professional-grade results instantly...

If you freelance or run an agency, you know the mess: leads coming in from DMs, referrals, and random platforms, proposals in Google Docs, projects in Notion or Trello, follow-ups sitting in your head until they're late. Five tools that don't talk to each other and things quietly slip through.

thinqspace pulls it into one flow, bring in leads (add manually or import from a spreadsheet), keep them in a pipeline so nothing goes cold, send proposals without switching apps and turn a won deal straight into a trackable project.

Still early and building in the open. If you try it, I genuinely want to hear what's missing or what feels off blunt feedback is the most useful kind.

I recently built WhoKnowsMe, a web app where people can create quizzes about themselves and share them with friends.

The main goal was to remove as much friction as possible no sign-ups, no app installs, and no ads. The entire quiz creation process takes less than two minutes, and friends can join directly from a group chat.

I'm building PulseBoard an uptime monitor with an AI assistant (Vigil) that explains why your site broke, not just that it broke.

Here's a real example from a live site recently:

The Incident:

• A 404 error appeared on the site at 04:10:01 UTC

• Average response time: 570ms (consistent with baseline of 583ms)

• Uptime dropped to 93% (from baseline 95.8%)
