So many complicated audio editor apps and softwares, so we made the simplest one

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

Here's why generic Gen AI tools make everyone sound the same on LinkedIn:

Have you also noticed that LinkedIn posts all have the same voice now?

If you scroll the app for 2 minutes, a big part of your feed will be filled with posts that have:

  • Short sentences.

  • One-liners.

  • "Not X. Not Y. But Z."

I built a Mac app that finds duplicate videos other tools miss

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?

LearnBite — AI-powered retention for YouTube learning

Hi, I am building LearnBite, a tool designed to make learning from YouTube more effective. LearnBite turns YouTube videos into structured learning sessions by breaking them into chapters and pausing after each section with simple AI-generated questions to help reinforce what you just watched. Instead of passively watching long videos, you can actively engage with the content and improve retention. We re getting ready to launch soon, and you ll be among the first to try it. Stay tuned for the launch announcement. Best, Ragav LearnBite

Why do sports fans still need 5 apps in 2026?

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.

How to Launch Products That Sell Before You Spend a Dollar on Inventory

The old way of selling online is broken. You design a product, order hundreds of units, pay for inventory, rent warehouse space, run ads and then hope people buy.

Most don't. 82% of small businesses fail because of cash flow problems.

What if you could flip that entire process? What if customers committed their money first, and you only produced what was already sold?
