I'm excited to share OpenAnyFile a free web app that helps you open and preview hundreds of file formats directly in your browser.
The idea came from a simple frustration: every time I received an unfamiliar file, I had to search for software just to see what was inside. I wanted one place where anyone could quickly open common file types without installing multiple applications.
Running Movies47 a streaming subscription with 32,000+ channels and VOD, works globally. The product sells itself once someone tries the free trial. The hard part is getting in front of people before they just renew their cable out of habit.
Curious what's worked for other founders in subscription or media products for organic discovery. Paid social gets expensive fast as a solo operator.
I recently launched a free ATS Resume Checker designed to help job seekers understand how well their resume may perform with Applicant Tracking Systems (ATS).
The tool analyzes important resume elements such as keywords, formatting, skills, sections, readability, and ATS-friendly structure. It provides practical insights that can help users identify areas for improvement before applying for jobs.
I built this as part of Global Tools Box, a collection of free online tools designed to make everyday tasks easier and more accessible.
Hey everyone! I've been working on Turborechner, a free online calculator hub, and wanted to share one of the tools: a percentage calculator.
Here's a weird thing percentages are everywhere in daily life, but most of us just trust the number on the receipt/app without actually knowing how it's calculated. That 20% off tag, your loan's interest rate, the battery percentage on your phone, even your exam grade it's all percentages, and yet almost nobody checks the math behind them.
So I built a calculator that doesn't just give you an answer it shows the actual formula and step-by-step working behind every result.
It handles 7 different percentage problems in one tool:
Hey Product Hunt, I m building InteliAds, a tool for KDP authors and self-publishers who run Amazon Ads for their books. Here s the thing. Amazon Ads can work, but managing them every day is painful. You have keywords spending money.
You have search terms getting clicks but no sales.
You have ACOS going too high.
You have good keywords that should be scaled, but they get forgotten.
And then you still need to check CPC, CTR, ROAS, bids, spend, orders, and campaign performance. So the real problem is not only running ads. The real problem is knowing what to do next. Should this keyword get a lower bid?
Should this search term be negated?
Should this target be paused?
Should this winner be scaled? That s why I built InteliAds. It helps monitor Amazon Ads 24/7 using simple IF/THEN rules, so authors can reduce wasted clicks, control bids, pause weak targets, find winning search terms, and protect their book margins. Right now, it is rule-based, not full AI yet. I wanted the first version to be simple, controlled, and safe, because authors should not feel like a black box is spending their money. I d really love feedback from KDP authors, self-publishers, Amazon Ads users, or anyone who has managed PPC campaigns for books. What would you need to see before trusting a tool like this with your campaigns?
Everyone tells you to contribute to open source, but nobody teaches the non-code parts.
Forking is easy. The real hurdles are keeping branches updated, resolving git conflicts, understanding licenses, handling PR feedback gracefully, and picking projects that actually merge your work.
Hi everyone! I'm Roland. For a while now I've been stuck on a problem that won't leave me alone: the web was built for human eyes, but the fastest-growing "visitor" to most sites is now an AI agent that can't actually read them.
Agents scrape HTML, guess at forms, and render a whole page just to find one price or one button. And every assistant wants a different integration. It started to feel like the early mobile web all over again: rebuild everything, once per platform.
So I started AI2Web - an open interoperability layer. You describe your site once, in a single manifest at /ai2w, and it projects to whatever an assistant actually speaks: MCP, ACP, AP2, REST, feeds. No scraping, no per-vendor rebuild.
It's fully open (CC-BY spec, MIT SDKs). So far I've shipped reference SDKs in 6 languages, a WordPress/WooCommerce plugin that makes a store buyable by AI agents (ChatGPT checkout, Google AP2), a Chrome "AI readiness" checker, and a discovery network so agents can find AI-ready sites.
