I'm an indie developer from Japan, and I just launched Kaikoku.

The short version: I found a notebook I wrote in junior high full of an entire "magic system" I invented (twelve zodiac spells, solar arts, seal-curses). Pure chuuni, that fantasy-prone teenage phase. Instead of cringing, I decided to actually build it.

Kaikoku is an antique pocket watch that lives in your palm. The chain swings on real physics. Snap the hunter lid shut and magic charges; open it and the day unseals. By night you wind the dial to cast one of twelve arcana; by day the sun answers with solar arts. Every hour it checks its keeper via Face ID.

Underneath all that staging, it's a genuinely functional clock app: alarms with six bells, a timer, a chronograph with Live Activities, an Apple Watch companion, widgets, and StandBy. The fantasy is the skin; the timekeeping is real.

Hey PH! I'm Uzma, a solo maker from Pakistan. On Oct 15, I launched The CLEAR Funnel Playbook a system that helps software companies discover hidden AI tools (Shadow AI) their teams use without approval.

My starting position: zero audience, zero ad budget, zero team. Just me and a playbook I wrote.

Results: #417, 0 points, 2 comments. No sales from PH directly.

But here's what I actually got:

Ever had a fast internet connection that somehow still feels terrible?

Video calls freeze, games lag, websites take forever to load yet your speed test says everything is fine.

After nearly 20 years working in the ISP industry, I've seen this frustration from both sides: customers struggling to explain their problems and support teams trying to identify what's actually wrong.

That's what inspired me to build Diagnostix360, a free Android app designed to make internet troubleshooting easier to understand.

Small business operators and founders often find themselves juggling marketing, SEO, reporting, hiring, and day-to-day operations without a dedicated specialist for each function.

We're building Revent AI Lab around that problem: a workspace of specialized AI agents designed to help with different business jobs while keeping humans in control of important decisions.

We're preparing for our Product Hunt launch on Tuesday, October 20.

Before opening the beta more broadly, we'd like to hear from other makers and operators:

I work on Mugen3D at SumeruAI, where we generate rotatable 3D previews from a single product photo.

A small exploratory test across six product categories left us with a harder question: how do you validate a view that the input photo never showed?

What we observed

• Robots, plush toys and collectible figures: shapes and material appearance held up better in these examples.

• Shoes: promising from some angles, but hidden structures and side views still needed review.

• Cosmetic bottles and watches: transparency, reflections, labels and fine details were harder to reproduce reliably.

Hi Product Hunt community!

As an engineer stepping into the software world, I ve spent a lot of time analyzing why field adoption fails so hard in the construction industry. Most traditional ERPs and project management tools feel like an administrative chore. Forcing a superintendent or project manager to fight complex web forms to log a daily diary after a 10-hour shift usually results in bad data entry or team frustration.

I believe the problem isn t the users, it s the interface. Field teams don't want another database tool; they want to communicate naturally with their technology.

To solve this, my team and I have been building LeanAIOS. Instead of rigid dashboards, we structured it as a Conversational OS. Powered by an AI squad (named Lea) that specializes across different construction disciplines, a site manager can literally just text or send a voice note like a standard chat to handle lookaheads, concrete conformity, and official daily PDF logs.

I'm Tabi, the maker of Storyvalo. It launched today, and I'd like feedback from people who turn business content into short videos.

The workflow starts with a webpage or PDF. Storyvalo drafts an editable script and scenes, shows source excerpts beside factual claims, and lets you review the narration and visuals before exporting a captioned video.

Here's a 60-second demo you can watch without signing up: https://storyvalo.com/examples

The consulting business in the demo is fictional; it isn't a customer testimonial.

A text-to-image AI where you see what prompts actually produce before you spend anythingA close friend of mine runs a small online shop. Last month she tried an AI image tool, spent $15 in two weeks, and quit. When I asked why, her answer hit me hard: I got maybe 3 images I could actually use. Every failed generation felt like watching money burn.

That one sentence made me question the whole economics of AI image generation.

Here s what I realized: The real cost of an AI image isn t the price per generation it s how many generations it takes to get one you actually love. Beginners don t fail because AI can t make good images. They fail because prompt-writing is a skill nobody is born with, and every trial-and-error costs real money.

So I built something to test this theory (I m the maker, being fully transparent here):
