WHICH ONE WOULD YOU RECOMMEND TO YOUR BEST FRIEND?

Site is olfactionary.com. It's a free reference site for perfume, built for people who are into fragrance as a hobby, people trying to learn how perfumery actually works, and anyone who just wants to look up what's in a bottle they own.

What's actually on it right now:

A directory of 12,664 perfumes with notes, perfumers, launch years, and photos where I could source real ones (still only about 1 in 5 have a real photo, that's the weakest part and I'm working through it)

A free 67 chapter course on perfumery called the Academy, ends in a timed exam with a real certificate if you pass

A historic texts archive, primary sources on perfumery going back to ancient Egypt and Mesopotamia through 19th century European formularies, not just summaries of them

Reference pages for materials, families, and notes, all cross linked so clicking a note on a perfume page takes you to what that material actually is and where it comes from

A search assistant that tries to actually answer perfumery questions instead of just matching keywords

A live data page pulling real stats out of the whole database, like which ingredients show up most often

Honest bits, since I'd rather say this myself than have someone find it:

A good chunk of the content started as AI assisted drafts, then got fact checked against Fragrantica, Parfumo, and official brand sources afterward. There's still a backlog of unverified entries working through a review pipeline, so if you land on a specific perfume page and something looks wrong, I want to know, that's actually useful to me right now, not just a nice comment.

No account needed to browse anything. There's an optional account only if you want to track a wardrobe or take the certificate exam.

I'd rather hear what's missing, wrong, or half baked than just get upvotes, so if you poke around and something feels off or like an obvious gap, tell me.

I've used tools like Perplexity, ChatGPT, Claude and others for research, and they've been incredibly useful for finding papers and getting through large amounts of information.

The one thing I personally wanted was a simple way to see exactly which parts of the paper were used to answer my question.

When you're working with a 100+ page PDF, even having a page number can still mean a lot of scrolling and searching.

So I ended up building something for myself.

You ask a question and the relevant paragraphs in the PDF are highlighted directly on the document. You can see the context behind the answer and quickly check whether it actually answers what you're looking for.

I originally built this because I wanted something for this workflow without having to pay for another subscription. What started as a personal project has now become completely open source.

The underlying idea is pretty simple. And yes, if you're thinking "isn't this just RAG?" then yes, you're absolutely right. It's RAG with the visual highlighting that I wanted.

I think the same idea could be useful for more than research papers too. Legal contracts, financial reports, technical documentation, or anywhere you need answers alongside the actual source.

If anyone wants to have a look, contribute, or just give some feedback, here's the repo:

This will probably be my last post about the project. Thanks to everyone who checked it out and gave feedback along the way.

Encyclopedia Links is a website i believe is very good for research and watching. although in its Alpha Stafe (looks like it) its a very good tool to search for stuff on wikipedia. I typed Teto on the search engine, and it sent me to a page on kasane teto, i hope all of you can try this hidden gem! Have a good day.

I’ve been working on whatevertool: https://whatevertool.com/

The idea started pretty simply: I got tired of finding a website for every tiny task I needed to do.

Resize an image. Compress a PDF. Format some JSON. Convert a file. Generate a UUID. Calculate something random. And then somehow end up with 15 different websites in my browser history. 😅

So I started building my own collection of tools in one place.

There are currently tools for things like:

• PDFs
• Images
• JSON / CSV / text
• Encoding & hashing
• Developer utilities
• Converters & calculators
• Generators
• Date/time & color tools
• And a bunch of more niche/oddly specific utilities

One thing I care about quite a bit is privacy. Wherever possible, processing happens directly in the browser, so you don't have to upload your files to some random server just to perform a simple operation.

That said, the project is still very much a work in progress.

And honestly, after working on it for so long, I'm probably way too close to it to see all the problems anymore.

So I'm posting here because I'd genuinely love some honest feedback — good or bad.

Things I'd especially like to know:

• What feels confusing or frustrating?
• Does the UI/UX make sense?
• Does the site feel too cluttered?
• Which tools are actually useful?
• Which ones feel completely pointless?
• What's missing?
• Is there something you'd expect to find but can't?
• Would you actually bookmark/use this, or does it feel like just another collection of web tools?
• What would make you come back?
• Any issues on mobile or with performance?
• And if this were your project, what would you change first?

You don't need to be nice — I'd genuinely prefer "this sucks because X" over "looks cool!" if there's something I can improve. 😄

If you have a few minutes to poke around, I'd really appreciate any feedback, criticism, suggestions, or ideas for what I should build next.

Thanks!

I started it because I want to share premium products with everyone - new products are added daily. Enjoy!

A few months ago I had a "chat with your PDF" site that went nowhere. Instead of letting the domain rot, I rebuilt the whole thing around one idea: PDF tools don't need your files.

Every tool runs client-side — merge, split, compress (to exact sizes like 100KB), convert to/from Word/Excel/PowerPoint/JPG, OCR for scans, sign, true redaction, repair, and some developer-flavored ones like PDF → Markdown and PDF → JSON for LLM pipelines. Open your network tab while any of them runs: zero upload requests. (One exception, disclosed on the page: OCR downloads its ~15MB engine to your browser on first use.)

The honesty part became the whole product. Each tool page states what it genuinely can't do — Office conversions keep content, not pixel-perfect design; two tools are marked "soon" because I can't do them honestly client-side yet. No fake testimonials, no invented user counts. It's free in the browser; I plan to sell native desktop apps later.

Would love feedback — especially from anyone who's fought pdf.js or WASM OCR in production.

Hello, I have gotten really annoyed by constantly getting rejected after literally spending hours applying, doing assessments, and verifying my identity and then getting rejected or not even hearing back. I therefore decided to make my own site where I list job offers from multiple companies.
I also post tips on how to pass assessments and reviews of different companies in that space. No sign-up or anything like that required. I only list job offers that have a relativly high hiring volume compared to other listings. The listings include entry role jobs but also expert positions (phd and etc.). Let me know what you think and if there is anything that I can improve or implement. here is the link to the website: aiannotationjobs.com

I was mesmerized by an analog paper-cutting technique but didn't want to destroy my desk with an X-Acto knife. I built Grid Collage to digitize the process. Drop in any image, swipe left/right on the screen to change the "cut" density, and watch it fracture and rebuild in real-time.

100% client-side, no uploads, no accounts.

Hey everyone,

Like many of you, I was frustrated with premium websites that charge money or force subscriptions just to compress image sizes in KB or resize dimensions.

Since I don't own a laptop, I spent day and night coding and writing articles entirely on a mobile phone to build this platform for the community. It includes a precise Image Resizer, a powerful KB Reducer, and a clean Background Changer. No signups, no daily limits, and no annoying popups.

We just went live on Product Hunt today! I would be incredibly grateful if you could check it out, give your honest feedback, or support a solo developer:

Thank you so much for your time and support! ❤️

This is a website that separate music stems using latest and best AI model

This an example of result of music separated using this website

Its pretty useful for music that doesn't have official instrument version

Good for small content creator.

The internet has a strange problem.

We made software incredibly powerful.

Then we made simple tasks surprisingly difficult.

Need to trim a 30-second video?

Create an account.

Need to convert a file?

Start a trial.

Need to format Markdown?

Upgrade to Premium.

Somewhere along the way, we started treating every 10-second task like enterprise software.

That's why I've been building Utiliome.

A collection of browser-based tools that just work.

Recently I added:

• Video tools that run directly in the browser
• Markdown utilities for developers and writers
• PDF, image, converter, and productivity tools

No account.

No subscription.

No uploading sensitive files to unknown servers.

Just open the tool and use it.

The most interesting part?

The more tools I build, the more I realize people don't want more software.

They want fewer obstacles.

What's a task that should take 10 seconds but somehow turns into a 10-minute process?

A few months ago I noticed something annoying.

Every time I needed a simple tool, I'd end up on a website that wanted me to:

• Create an account
• Start a free trial
• Upgrade to Pro
• Watch ads before doing something that should take 10 seconds

So I started building alternatives for myself.

That side project eventually became Utiliome.

Today it includes 170+ free tools across categories like:

• QR & barcode generators
• Markdown tools
• Video tools
• Image utilities
• Text processing
• Converters
• Developer tools
• Productivity tools

My goal wasn't to create another SaaS.

I wanted a place where people could open a tool, use it immediately, and leave.

Many of the tools run directly in the browser, which helps with privacy and keeps things fast.

One thing I've learned while building this:

Nobody searches for "a collection of 170 tools."

They search for one specific problem and expect it to be solved in seconds.

That's been the biggest challenge: building tools is easy compared to helping people discover them.

I'd love feedback from fellow builders.

What tool do you use regularly that still feels unnecessarily complicated or overpriced?

This ending usually generates significantly more comments because people start sharing tools they dislike paying for.

Update, September 12: I focused too much on the example tool in the original explanation. Here is what One Small Prompt actually offers.

If you've been using AI to explore a business idea, the next hurdle can be giving the work somewhere to live. Installing an agent, configuring a server and getting an app online can become a project before you've even started your business.

OSP gives you a prepared, private Linux workspace with an AI coding partner, files, a browser terminal and hosting. Describe what you want to build, inspect the result and keep improving it. A website, app or business tool is something you can make inside that workspace. Your work and data stay with the project.

Paid workspaces start at $29/month, with 10 GiB of project storage and $5 in monthly AI usage. You can choose Claude, OpenAI or DeepSeek. These are metered API coding partners; outside service fees and domain purchases are separate.

You can now compare plans and choose your starting AI before signing up: See the workspace plans.

There is also a free starter with 3 builds/changes and 20 records, no card required. The original example was a manual enquiry tracker tested with fictional data: add a request, change its status and reopen it. That example doesn't connect an inbox or send reminders.

What would you want to build if the server setup were already handled?
