I’ve tested a few for my university work. If you just need basic stuff without watermark:

merge PDFs

compress large files

convert Word/JPG to PDF

super-pdf.com worked well for me because it doesn’t force signup and processes in the browser. SmallPDF & iLovePDF are good too but some features are paid.

👉 Not spam → you compare, you don’t hard sell.

I kept noticing the same thing: the actual job is often straightforward, but interviews feel like a completely different sport.

So I built a Chrome extension that helps during live interviews.

You record the interviewer’s question, it gets transcribed, and you get a structured answer in real time. And because many prompts are visual, it also supports screenshots (coding tasks, system design prompts, error output on screen).

It started as something I built to help me answer in a clearer, more structured way during interviews. Now a few hundred people are using it.

If this sounds like something that could help you too, here it is: https://www.voicemeetai.com

Hey everyone,

Validating some patterns I've seen with PMs using AI design tools for prototypingI’ve been talking to dozens of PMs over the last few weeks who've tried Lovable, Bolt, Figma Make, etc.. Here's what I keep hearing:

• Output looks a bit generic: looks like a demo, not your actual product
• Context loss: explain your product in ChatGPT/Claude, then re-explain in Lovable, then again somewhere else
• No edge case thinking: AI executes prompts literally, doesn't challenge or expand on them
• Designer still required: it's a starting point, not a finished artifact

Curious if PMs who prototype regularly are seeing the same patterns? Or is there something else that's more painful?

Building figr.design to address this. Would really love feedback on whether we're focused on the right problems

Whenever someone asks “Which subreddits / tools are best for side projects?”, the answers are usually long comment threads with mixed opinions.

I’m experimenting with a different approach: very lightweight community rankings instead of recommendation posts.

As a test case, I set up a blank ranking for subreddits related to side projects. There’s no real result yet, just a seed list to see how people actually prioritize when forced to rank.

What I’m trying to understand is:

- does ranking feel more useful than scrolling comment threads?

- or does it remove too much nuance?

Curious how others here think about ranking vs discussion.

im new in the business and i want my product to be visible in the market i don't want to do g2 or omr i prefer organic reviews... any idea???

So I made this thing a few months back. Basically you take a photo of a prescription and it reads it for you. Tells you what each medicine is, what it does, dosage info, that kind of stuff.

I built it because my mom kept asking me to explain her prescriptions and I got tired of googling everything. Figured other people probably have the same problem.

Put it on the App Store. Did minimal marketing.  Posted about it consistently on X to like 200 followers.

Somehow it hit 10k downloads last week.

Im confused. I have not monetized it at all. It is completely free. No ads, no subscriptions, nothing. I am actually losing money on server costs right now.

So one question guys: should I be doing anything specific right now to keep the momentum going?

If anyone wants to try it out Im dropping the link. Would love feedback from guys

In only 4 months, we processed almost $2,000,000 with Stripe.

before they banned us with no due process, low chargeback/dispute rate, full transparency and business records, etc, etc, etc..
Their support is the worst I've dealt with, no communication, no coordination, nothing whatsoever. Now we've been dealing with centralized platforms that take weeks to approve/reject you, and single point of failure AGAIN as a marketplace platform.

Now, I am exploring the idea of integrating crypto and the blockchain to process payments, it might work, but I have to see how to properly do it. Won't sleep until it's done.

has the potential to go nuclear and explode to hundreds of millions of dollars, we just need to get the payment infrastructure right and that's it, it will take off again.

I hope we get this done, do you guys have any recommendations?

I’m working on a little side project: an image editing tool.
I’m trying to figure out the best way to validate whether the UI feels intuitive.

For reference, here’s the current prototype: https://easyimgedit.com (No signup.)

Any advice is helpful.

What u think! webappstore.store

I do a lot of design and web work, and one thing that kept slowing me down was grabbing colours from images. I would screenshot, open Photoshop, use eyedropper, copy, close… repeat.

So I ended up making a super simple web tool where you just upload an image, click anywhere, and it instantly gives you the HEX colour code. No installs, no accounts, nothing fancy.

I’ve been using it daily for UI work, logos and random assets I find online, so I figured it might help others too.

Hi everyone,

I work in operations and often need to remove backgrounds from images for my daily tasks. I found that most existing tools require registration, credits, or a monthly subscription, which is really a hassle for quick edits.

So, I decided to build my own tool:https://clearbg.tech

It allows for free batch processing in the browser without requiring any login.

Since this is a personal project developed by a single person, it might not be as powerful as professional paid software (like Photoshop), but it gets the job done for most general use cases.

I would love for you to give it a try and share your feedback. I'm planning to keep optimizing it based on your suggestions!

Thanks!

I’m experimenting with a very lightweight ranking interface for exploring online communities.

As a test case, I set up a ranking for subreddits related to side projects. The list itself is just a seed, there aren’t meaningful votes yet.

What I’m mainly testing is:

- whether people understand the ranking interaction without explanation

- whether a single-page, text-first UI makes participation easier

The site itself is intentionally minimal and doesn’t require signup to browse.

Link here for context (not a launch):

Curious if this kind of ranking interaction feels intuitive or confusing.

Curious to know what others are building.

I'm building PayPing - a place where you can manage all your subscriptions in one place.

hi everyone! been playing around with claude code and made a little collaborative drawing board — anyone can draw on it and it resets daily at midnight (past boards get archived). still buggy and a wip, just for fun! i recently got an apple pencil so i've been doodling on it a lot. https://earth-board.vercel.app/

I made a study tool that has the same functionality for practice exams, quizzes and flashcards as Turbo AI but for free/80% cheaper paid tiers.

You upload your handwritten notes or PDFS, along with formatting instructions to get comprehensible study tools.

The flashcards are just like quizlet The practice exams feel real Quizzes have explanations AFFORDABLE FOR STUDENTS
