Hey everyone!

Tomorrow (Sep 2) I'm launching KnowledgeOS on Product Hunt my solo-built, privacy-first AI that answers employee questions from company documents.

The core idea: while every AI tool sends your docs to the cloud, KnowledgeOS runs 100% on your own machine. Documents never leave your infrastructure.

Quick highlights:

Hi everyone,

I built Translate Workspace to solve a simple but annoying problem: constantly opening new tabs just to translate text.

It lets you translate anything directly on the page you're reading, keeping your workflow intact.

I recently launched it and would love to get your honest feedback, thoughts, or support on my launch page!
Free to try, no credit card.

We are building FounderFlow around a painful founder experience.

I opened an important government-related email.

I completed one portion of the required survey.

We just launched TruthDeck on Product Hunt

AI-powered credibility scores for Indian startups know if the hype is real before you invest or join.

We built Protocall five years ago, used it internally every day since. But when we decided to launch, we knew there were still plenty of things to fix and add. So we had two options:

1. Don't launch and spend another year making it great on our own, going only off internal team and client feedback.

2. Find people who'd actually share their feedback and help us get there much, much faster.

One decision I went back and forth on for a long time: whether to add rewards for testing and feedback, or just ask people nicely.

Since testing a product properly, reporting a bug that's actually reproducible, or writing up an idea that's usable looks like real work. It's literally someone's job internally, our product owner and QA engineers get paid to do exactly this.
Asking strangers to do the same thing for free felt like asking a favor we wouldn't ask of our own team without paying them. So we set up a small pool: $10 to $200 per contribution.

I sell Next.js website templates, and the thing that annoyed me most as a buyer in that market is that you usually cannot see the product before you pay. You get three screenshots and a promise.
So every one of my 20 templates is deployed and browsable, free, right now: https://cenkkurtoglu.com/templates
Every card there has a live demo link to the deployed site. Click through, open the sub-pages, resize the window. If they are not what you want, you have lost two minutes instead of $79.
What they are: 20 multi-page starters, one per niche (SaaS, agency, e-commerce, real estate, restaurant, gym, dental clinic, hotel, law firm, course platform and ten more). Next.js 15.1, React 19, Tailwind 3.4, 5-8 pages each, editable TypeScript source, commercial licence for client work.
What they are not, stated plainly because I would rather lose a sale than an argument later: these are frontend starters, not full-stack SaaS boilerplates. Forms, cart, booking, auth and checkout are demo UI. You replace the placeholder content and wire your own backend. If you need auth and payments already working, buy a boilerplate instead, not this.
One bundle, all 20, $79 one-time. It is on Product Hunt tomorrow morning. I am not going to ask anyone here for anything on launch day, but if you have used template bundles before I would genuinely like to know: what made you regret a purchase? I would rather fix it before someone pays than after.

Hey Product Hunt community!

Here s a situation I kept running into every winter:

I m curled up on the couch or in bed with my Mac. My right hand is comfortably using the trackpad, and my left hand is either tucked under a warm blanket or holding a hot cup of coffee .

Then comes the annoying part: I need to copy & paste a piece of text.

I kept noticing the same problem with Airbnb stays:

Guests constantly ask:

• What s the WiFi password?

• How do I check out?

• Where can I park?

• What are the house rules?

• How do I use the TV/AC?

• What s good to do nearby?

And hosts end up answering the same questions again and again.

I built Vificil because I wanted to use browser-based AI tools like ChatGPT and Claude with real local projects without constantly copying code and files back and forth.

Vificil prepares the project context, then automatically detects, validates, and applies the structured patch ZIP generated by the AI.
