I built a private Mac vault that opens from the notch — losing my own API keys drove me to it 🔑
The problem that broke me: I was constantly losing my own stuff an API key I'd pasted into some chat, my bank account number, an app description I wrote once. All scattered across browser tabs, Notes, and old AI conversations. Every lookup was a 30-second scavenger hunt, ten times a day.
So I built Cubby a native macOS menu-bar app that keeps the little things you look up all day in named compartments you control ("Personal", "API Keys", "Bank").
How it works: hover the notch (or hit Space) a glass island drops from the top type to filter hit return it's copied. About a second, start to finish.
What makes it different:
InvoicePilot — invoicing built for freelancers, agencies, consultants, and small businesses
Just launched InvoicePilot on Product Hunt a simple invoicing platform for anyone who bills clients regularly: freelancers, agencies, consultants, and small businesses.
What it handles:
Professional invoice creation in seconds
Getting traffic but almost no product clicks – what are we missing?
We're getting traffic, but almost nobody clicks on our individual product pages. I can't figure out why.
We've tested different layouts, but visitors still leave after viewing the catalog.
Is it because:
the product names are unclear?
the page doesn't explain what each product actually does?
or the design doesn't build enough trust?
I narrowed PrivMuse to the message you are afraid to send
After 13 days, I learned that "private AI letters" was too broad to create a clear first action.
I did not turn PrivMuse into an AI companion or therapy bot. I narrowed the entry point to one concrete moment: you have a difficult relationship message after silence, conflict, or mixed signals, and you want to know what could go wrong before sending it.
The focused V3 flow is:
1. Describe the situation.
How we cut our proxy costs by 40% (without sacrificing reliability)
Let's talk about something nobody in the proxy industry likes to discuss: how easy it is to blow your budget on proxies without even realizing it.
We've been there. Early on, our proxy bill was growing faster than our actual usage, and we couldn't figure out why. After auditing everything and making some changes, we cut costs by roughly 40% while keeping success rates steady. Here's what actually worked:
1. Pick the right pricing model for your usage pattern
If your traffic is spiky and unpredictable (project-based research, periodic audits), pay-as-you-go will almost always be cheaper than a fixed monthly plan. But if you're running steady 24/7 automation, a committed tier usually wins. We were on monthly plans for everything switching our variable workloads to usage-based pricing saved us the most money by far.
Roast an idea: adding grammar checking via SDK to any app boosts retention
Hey there! I am one of the founders of Linguix - we build AI writing assistant and now we are diving into developing our API and offering an easy way to integrate it via API. My idea, that has some proof via PoC projects by now, is that when you add grammar checking dialogues to your app, people will spend more time within it = improved retention rates. Also, those dialogues can potentially be used to promote core product features, which should improve APRS/ARPU.
What do you think? Would you be open to testing this kind of product (Grammar Check API/SDK) for free?
Launching Torziva on Product Hunt on March 8th — First-Time Founder, No Big Audience, Just Belief
I recently saw someone with 10k+ followers launch and still finish 6th. That hit different.
Now I'm launching Torziva on March 8th.
I built an AI virtual try-on tool for online fashion stores customers upload their photo and instantly see how clothes look on them. Fewer returns, more confident buyers.
I'm not a marketer. No big following. Just a solo founder who believes this solves a real problem.
What I've done so far:
Built Torziva from scratch solo
Set up Coming Soon page on Product Hunt
Started sharing in communities for early feedback
What I'm nervous about:
No big audience or marketing budget
First time launching anything publicly
Don't know if the right people will show up
If you've launched before, I'd love to know:
Did you reach out to strangers or only your network?
How did you get your first real user after PH launch?
Trying to go in prepared, not just hopeful

Beyond Vertical AI: The Case for a Knowledge-Work Harness
Almost every knowledge-work domain now has a decent tool. Harvey and Legora for legal. Rogo for finance. All decent and all narrow and not accessible to everyone.
Coding has something the rest of knowledge work doesn't: harnesses. Cursor CLI, OpenCode, Codex, Claude Code general-purpose agents that turn a model into a real force multiplier.
So where's the equivalent for everyone else? Why is there no publicly available harness that's a genuine upgrade over Claude Code or Codex for the deliverables professionals actually ship Excel models, research reports, decks, PDFs?
That's what we built at Associum.
We manually tested 200+ APIs so you don't have to – Meet Apives.com
Hey Makers!
As builders, we integrate APIs daily. But finding reliable, actively maintained APIs with good documentation feels like searching for a needle in a haystack.
To solve this for myself and the developer community, I built Apives.com. It s a curated platform featuring over 200+ manually verified APIs that you can search and test directly inside the dashboard before adding them to your codebase.
No more broken integrations or zombie endpoints.
