Hi community, I built PixSathi to help students resize exam photos, merge PDFs, and build resumes without any paywalls. All tools run locally in the browser. Check it out: https://www.pixsathi.in"

Hello everyone!
I'm Atul. I've been a software engineer for the past five years, and I'm currently a graduate student in Computational Sciences at the University of Vienna. As a student, I've tried many note-taking apps, but none of them really cater to the needs of students, especially in the AI era. So I built my own: Pen Buddy.
Pen Buddy has everything a student studying with AI could need. My goal was to recreate the experience of studying with a really smart friend, and to solve one of AI's biggest problems for students: getting answers without actually learning.
That's where Buddy comes in. Buddy is a built-in, AI-powered conversational companion. It can talk with you, give you hints when you're stuck, notice when you're struggling, and adapt to help you through it. When you turn it on, it can see your screen and your PDFs. It can draw out explanations, flowcharts, and graphs, read and write mathematical equations, and work through LeetCode problems, brain teasers, or anything else you throw at it. It also prepares briefs, summaries, and flashcards from your lectures and notes.
I've always heard that you should build something you'd use every day, and now I see why. Pen Buddy has replaced my old note-taking app, and every day I'm working to make it the best experience possible for students.

I am part of the Mugen3D team at Sumeru AI. While writing about Atlas and Genie 3, I kept coming back to a product question: when is exploring a generated world enough, and when does an application need persistent, reusable 3D assets?

The distinction changes the implementation:

• Live world generation: the model produces what comes next as a user moves. This is compelling for exploration and simulation, but consistency, latency and inference cost become product constraints.

• Spatial generation and reconstruction: Atlas supports camera-controlled video, novel views and explicit 3D outputs. The relevant tradeoff depends on the output mode, so I would not treat it as only a video generator.

• Asset-first applications: our Mugen3D work starts with a reusable 3D representation, then adds rendering, animation, dialogue and interaction. This shifts work toward asset quality and runtime engineering, including memory, compression and integration.

There is no universal winner here. Single-image 3D still infers unseen surfaces; small text, reflective materials and complex geometry need review. Reusable assets do not remove rendering or animation costs, and this is not a benchmark comparison with Atlas or Genie 3.

Hey Product Hunt!

Building on the conversations around our Virtual Card feature, we wanted to highlight another practical benefit teams are finding useful lately:

• Every card has a single purpose. No mix-ups, no unclear transactions.

• Unauthorized purchases simply can t happen. If the card isn t approved for the vendor, it won t go through.

• Budgets stay exactly where you set them. Limits are locked in, and alerts tell you the moment a transaction happens.

Hey everyone! I build small free tools for developers under my studio LogicStack, and the latest one is a portfolio builder.

The frustration behind it: every portfolio builder I tried either charged monthly or locked me into rigid templates. And I kept seeing good developers with weak portfolios just because the tools were expensive or ugly.

So I made one that's free, no account needed pick a template, add your work, share your link.

Here's my real question for this community: when you open someone's portfolio, what makes you stay vs leave in 10 seconds? Projects, writing, design, something else? I want the templates to reflect what actually works, not my assumptions.

Makers, we are all too close to our own products. I see so many brilliant tools launching with headlines that are way too tech-heavy or confusing for the average user. Post your current landing page headline below and tell me exactly who your target customer is. I ll reply with 2 or 3 cleaner, high-converting copy alternatives as an English major.

Hello everyone!

My friend s mother lost around $40K on a fraudulent crypto investment. She believed she had found a golden opportunity and risked all her savings, only to be devastated when the scam unfolded. Witnessing her pain and financial loss, I both a coder and a cybersecurity specialist realized something had to change.

That's why I created StopScam: Scam Detector Pro. I built this app to provide a reliable tool for protecting your hard-earned money. With StopScam, you can manually upload screenshots, images, or take photos of digital content, physical letters, and even PDF files. Our advanced AI, machine vision, and OCR technology analyze them for scam signals.

I first installed StopScam for my family and close friends, ensuring they would never face the same hardship. And this is just the beginning! In the near future, I plan to add even more useful features to further safeguard your loved ones from fraud. StopScam is designed to be your comprehensive shield against scams, keeping you one step ahead of fraudsters.

Hey PH!

Hi everyone,

I m Sohail, and I ve spent about 13 years in the corporate world. My path hasn t been a straight line. I ve worked as a crypto developer, in fintech, and in research and business development. Through all of it, one thing kept coming back: email marketing. Every role I had ended up touching it in some way, whether that was campaigns, CRMs, automations, or the servers behind them.

These days I run lifecycle marketing automation and CRM across several products. I ve seen companies sign expensive multi-year contracts for email platforms and still struggle with messy data, slow workflows, and no clear view of which emails actually bring in revenue.

Why email, and why now
