So this started out of pure annoyance. I'd copy something, copy two more things, and the first one was gone. Win+V helps a bit, but it only holds 25 items and wipes them when you restart.

I m Luca, a developer from Bucharest, and I just spent two months building an app that nobody asked for. :))))

Here s how it started. Every time I planned a trip I had Skyscanner, Booking, Airbnb, Sixt and Instagram open at once. I ended up with 30 tabs, no idea which flight I d picked, and zero energy left for the actual vacation. So I did what any reasonable person would do: I built my own app instead of just closing a few tabs.

Travel Force has flights, stays, car rentals, visas and events in one place. It s free, because I can t in good conscience charge for something this early.

I've noticed something.

AI is everywhere, but running it privately on your own laptop is still way too complicated.

Hi, I'm Mesmer Lord, the solo founder of AdMakeAI. I started it because the bigger brands a small business competes with on Meta aren't smarter. They have a creative team and test far more ads.

What it does: you upload a product photo and it makes finished ads in every Meta placement size, plus UGC-style 9:16 video ads with AI avatars. It also tracks competitors' live ads in the Meta Ad Library and shows which ones they keep running, so you can remake a format that's working with your own product. Finished ads go to your ad account as a draft campaign through Meta's Marketing API, and there's an MCP server if you'd rather work from Claude or ChatGPT.

A question for anyone running ads: when you start testing a new product, how do you choose the first formats? Copy what competitors keep running, start from proven templates (product-in-hand, before/after, testimonial), or something else?

New accounts get 30 free credits with no card. If you'd like to test it properly and tell me what's missing, I'll give you a free month of Starter (500 credits): sign up, then email support@admakeai.com with your account email.

We re building Solous (Solous.net), a place to keep the things you don t tell anyone. Before we launch, we want to get the trust part right.

So, honestly: what would it take for you to write something truly private in an app? End-to-end encryption? No account required? Knowing who s behind it? Or is it something you d never do?

Hi everyone!

I m an independent iOS developer, and I created Optima Dash to make crypto market monitoring more visual, intuitive and accessible.

Instead of switching between multiple screens, you get a customizable crypto dashboard that brings your essential market information together in one place.

What makes Optima Dash different?

I lost a potentially valuable professional connection because of one business card

In 2021, I attended a peace conference in Washington, D.C. After one of the sessions, I had a great conversation with a USAID representative. He gave me his business card and asked me to email him because he would soon be visiting New York, where I was living at the time.

Hi PH, I'm building Prepd, an interview practice site for software engineers.

Something I keep seeing: producing code and architecture diagrams is getting cheap, because an assistant gives you a decent first draft in seconds. What's getting more valuable is the review. Spotting the off-by-one, the shared state with no lock, the API that doesn't exist, or the design with Kafka and five services for 50 writes a second, and then saying "this is wrong, here's why" clearly.

AI-assisted interview rounds test exactly that. So Prepd now has: AI-written code with planted bugs to find and fix, system design drills with written feedback on your trade-offs, and a free animated learning path that shows what each scaling step fixes and what it breaks.

I also wrote up a free checklist for reviewing AI-generated code and designs, with phrases for pushing back and two worked examples: https://prepd.tech/guides/review...

Hi PH, I'm David, a solo developer. I've spent about the last year building apps on my own, and most of my code now gets written with AI coding agents. The thing that kept breaking my focus was checking how much usage I had left and when it would reset, which meant switching over to a terminal.

TokenWatch Usage Monitor is what I built for that. It shows usage and reset times for your AI agents on one phone screen (Claude, Codex, Copilot, Cursor and others are supported). I leave my phone in a dock beside the monitor with it open.

What it does:

• A notification when a limit resets

• The gauge changes color when you're using it up faster than the time that has passed

• Pixel monsters show up on the gauges. Tap to catch them, and there's a collection book and a ranking

We're opening the Synesis OS Private Beta waitlist.

Your AI knows how to answer questions.

But does it actually know you?

Your goals, commitments, decisions, and conversations are scattered across dozens of apps. Every day, you spend time reconnecting information that should already work together.
