Hey Product Hunt! I'm the founder of Kinetic Mingle, I've been looking at threads here for a while and figured it's time to say hi!

What I Built

Kinetic Mingle is a video-first dating platform for adults 21+. We focus and lead with the the personal interaction part of online dating. It's front and center of our platform. Instead of static photos, filtered glamor shots and robotic swiping, users connect directly through video chat, video messaging, voice notes, and verified profiles. Our AI coaching assistant is a highlight feature. It uses adaptive learning tailored to individual user activity. You get your own personalized AI agent. Its a real gem!

I kept running into audio editors that were just overwhelming. Too many menus, too many features I didn't need and the installs always took forever.

So we made Brisk Audio, a browser-based tool that s just simple. You can record, edit, remove vocals, reduce echo, adjust speed, and more. All in your browser with nothing to install.

It s really aimed at anyone who just wants to record or edit audio fast. Creators, podcasters, musicians or just someone trying to clean up a quick recording.

Give it a try and see how straightforward it feels: https://briskaudio.com

I m one of the creators of Lingogrind, a small startup we re building to help people learn German and prepare for official exams (Goethe, telc, TestDaF).

We noticed that many learners struggle with two things:
structured exam preparation
consistent practice with real exam-style exercises

So we started building Lingogrind to make exam prep more structured, focused, and a bit more motivating.

Right now we re in early beta and looking for a small group of testers who are learning German or preparing for an exam.

Ask any AI chatbot "why is my user retention dropping?" and you'll get a decent list of suggestions. Organized, readable, and almost entirely useless for hard problems.

Why? Because complex problems don't yield to a single perspective. Charlie Munger spent a lifetime proving this. His answer the one that helped build Berkshire Hathaway into one of the greatest investment machines in history was the Latticework of Mental Models: a cross-disciplinary framework that forces you to triangulate truth through multiple lenses before reaching a conclusion.

FunBlocks AIFlow brings this philosophy into an AI-powered thinking tool. It doesn't just answer your question. It thinks about your question the way Munger would.

Hey PH!
I'm a solo developer, and I've been working on Dup a macOS app that finds duplicate photos and videos using perceptual hashing.
The problem I kept hitting:
I had 200GB of media scattered across folders exported at 4K and 1080p, converted MOV to MP4, shared via AirDrop (which renames files). Every duplicate finder I tried said "no duplicates found." They only match identical files.
What Dup does differently:
Instead of comparing file names or raw bytes, Dup compares what your files actually look like. Same vacation video at 4K and 1080p? Different codec (H.264 vs ProRes)? Renamed after AirDrop? Dup catches all of it.
I tested it against a popular paid tool on the same 200GB folder:
- Other app: 3 duplicates found
- Dup: 47 duplicates found, 38GB recovered
How it works:
- Perceptual video hashing (two-pass with duration verification) built in Rust
- Perceptual image hashing for photos (handles HEIC, RAW, JPEG)
- 100% local processing nothing leaves your Mac
- Free to scan, Pro for unlimited cleanup ($14.99/yr)
I'd love feedback on:
1. Is the video dedup angle compelling enough to stand out in a crowded market?
2. Any features you wish duplicate finders had but don't?
3. Would you pay for this, or expect it to be free?

Hi everyone

I m an indie developer and I recently built an app called Deadlinr.

The idea came from a simple problem: I kept losing money because I forgot about subscriptions and expiry dates.

So I built Deadlinr to track things like:

Sport isn t broken, but the way we experience it is outdated.

It s 2026, and fans still juggle multiple apps to follow one game.

Scores in one place. Conversations somewhere else. Predictions on another. X for everything in between.

Hey PH! Excited to share what we've been building at Super Sense AI.

Here's the problem we kept running into: most AI tools are great at working with documents and static files, but real businesses run on live systems databases, CRMs, APIs, and operational platforms. By the time you export data and feed it into an AI tool, it's already outdated.

Super Sense AI solves this by connecting directly to your live business systems and letting AI query, automate, and act on real-time data. You can set up separate AI environments ("Senses") for each team so everyone gets accurate answers from the data sources they actually use.

I'm a Business Analyst on the team and I use it daily it's completely replaced my old workflow of jumping between dashboards and stitching spreadsheets together.

reading a 40 page document is pain.

so i built something that lets you:

snap any section with Alt + drag and ask AI about it upload multiple PDFs and switch between them
