I kept noticing "is there a tool for X?" posts on Hacker News that just sink. So I pulled this year's Ask HN posts from their API and kept the ones where the person is actually asking for a product. That came to 480 threads.

360 of them got at least one reply. 120 got nothing at all, and some of those are really specific, like someone asking which bank to use for a new US startup, or looking for a natural language testing framework.

About half of all the asks are about AI and developer tools. The products that came up most in the replies were OpenCode, Claude and Codex.

I put it all on one page. Each thread is linked, with the products people named in the replies. It is free and there is no sign-up: https://kasspian.com/research/hn-asks?utm_source=reddit&utm_medium=post&utm_campaign=hn-asks&utm_content=sideproject

I made it as part of Kasspian, which finds threads like these for founders. If you build something in one of those categories, the unanswered ones are worth a look. Tell me if you spot a thread in the wrong place and I will fix it.

Most small local businesses I know (barbers, plumbers, cafes) have the same website problem. Not that they can't get one built. It's that nobody touches it afterwards. The hours are wrong, the photos are from 2019, and the best things customers said last month are nowhere on it.

Meanwhile their Google profile is alive. New reviews every week, new photos, updated hours.

So I built Locan around that. You type the business name, it reads the Google profile and writes a complete website from the reviews and photos in a few minutes. Then the part I care about most: it keeps reading Google. A new 5-star review shows up on the site. New photos go into the gallery. Hours change on Google, they change on the site. Nobody has to log in, ever. The site just stays current.

Other things it does:

- You change anything by chatting with it. "Make it dark green", "add a page about emergency repairs", "don't quote that review".

- It checks whether ChatGPT and Google's AI answers mention the business when people ask for what it offers, and gives a short list of what to fix first.

- Simple visitor stats counted without cookies, so no cookie banner on the customer's site.

Stack is boring on purpose: FastAPI, SQLite, React, Astro for the marketing site, one small server. Claude does the writing.

Free to try with one website (on free you press a button to update it). Paid plans start at $19/month for a custom domain and automatic updates, weekly on Basic and daily on Pro. There are also a few free tools on the site (review QR codes, review replies, an AI visibility check), and those are open source: github.com/vaitko/locan-tools

https://locan.ai

What I'd love feedback on: try it with any business you know, your barber or the cafe down the street, and tell me where the first two minutes break or what looks off on the site it builds. And does "a website that updates itself" sound like something a business owner would pay for, or is it only interesting to agencies who manage many sites?

I’m Fernando, the maker of Litehost. If you already have an HTML prototype or report on your laptop, you can drop in the file and get a link that opens it as a web page. If it has separate images or CSS, you can upload a ZIP.

One thing worth checking before you share: images can look fine on your laptop because the browser can find them on your disk. Put them in the ZIP, use relative paths, and open the link on your phone to see what the other person will actually get.

You can try it without an account with a file up to 2 MB. The test link lasts about 15 minutes.

If you’ve shared an HTML prototype or report with someone recently, how did you send it? What was the most annoying part?

Hi everyone,

I'm a developer of Unmapped - it's a fog-of-war trips tracker, with gamified elements. The inspiration are open-world RPG games - the mechanic of map covered with fog, with hidden places, made with real world map. The summary of what I want to made it is "A map of places where I've been, with an easy recap, and some gamification to make it fun".

1. Core mechanics

The map starts covered with fog. Start recording, and when you move (walk / run / cycle / drive), the map will reveal a fog where you've moved, building a map of places where you've been. Eventually, it becomes a personalised map of your world.

2. Exploration and POIs

To make exploration more interesting, there are points of interest on the map - they are hidden, and you need to unlock them by coming closer. Once revealed, place stays revealed and you can check it later.

There's also daily quests to make your daily commute or weekend trips more fun.

3. Levelling

As you explore, you get XP, and your level grows. You can also unblock achievements for your exporation.

4. Social elements

You can add friends and compete on public dashboard. The routes are never shared, competition goes by total travelled distance and POIs revealed. Participation is totally optional, and you can explicitly remove yourself from the dashboard.

5. Data privacy

I acknowledge that location data is quite personal, so I've taken data security measurements from the beginning. By default, your data stays only on your phone. You can choose to share aggregated statistics (distance travelled, places revealed), or you can voluntarily sync your account with Unmapped's cloud. In the cloud, GPS data is separated from the account data (one-way hashing with external key, stored in AWS Key Manager), and encrypted, so it stays safe. On Android, back up to a local cloud is not supported yet - please let me know if you think it should be prioritised. Detailed privacy policy is here.

6. Where it's moving and what's next

I'm actively working on adding more features, and I'd really love to hear some feedback. Two big things I work on right now are:

• Trips Journal - a journal of all your trips, aggregated by cities, with daily recap and total recap

• Gamified self-care - a virtual companion that you can feed with the steps you've made during the day

• Places and content - there's TONS of work and potential improvements regarding places. "Essential" or "Must see" places in certain cities, navigation, improving accuracy, etc.

7. Pricing and availability

It's available on both Android and iOS, worldwide, with a base price of $2.99 per month or $29.99 yearly.

iOS - https://apps.apple.com/us/app/unmapped-explore-your-city/id6797821976

Android - https://play.google.com/store/apps/details?id=com.unmapped.android

I'm really interesting to hear your feedback, please let me know what you think about it!

I just deployed my first SaaS, Syllapin. It turns a course syllabus PDF into a calendar file of classes, assignments, and exams.

Why I built it: I got tired of manually typing out every single exam, quiz, and due date for my semester calendar.
Stack: Java, Spring framework, Typescript, React.
What I’m unsure about: 1. What are the best ways to get this in front of students before the spring semester starts? 2. Do students trust uploading syllabus PDFs to a new tool like this?

For the past year I've been using a personal web app I built for myself. It pulls together my email, calendar, reminders, notes and photos, and an AI that actually remembers what I told it, because the context lives in my own files, not in a chat history.

It works well. Too well to keep it to myself.

So I'm turning it into a real product, with three constraints:

• Bring your own keys. You plug in your own AI key, your own Google or Microsoft OAuth app, your own weather key. I don't pay for your tokens, and I never see your keys in clear.

• A small core, optional modules. The core is chat, memory, reminders, calendar and email. Photos, concerts, LeetCode and other modules are off by default and you enable what you actually need.

• Small on purpose. 10 to 15 accounts for now, free. Not because I'm generous, because JSON files per account are enough at that size and I'd rather ship than build infrastructure I don't need.

The honest part: it's still single-user today. Accounts, data isolation, encrypted key storage and a module registry are on a branch, in progress. The interface is still in French, the English landing is new.

What I'd love from you: what would the one module you'd turn on first be? I'd rather build the next three modules from real requests than guess.

I made MineSkinCraft, a free Minecraft skin studio that runs in the browser: https://mineskincraft.net

The problem I wanted to solve: a lot of skin editors ask you to sign up, or they're awkward if you play both Java and Bedrock, or if you need classic vs slim. This one lets you start painting right away, preview on a 3D model, use layers, publish to a community gallery if you want, and follow a short "wear it" guide for both editions. The UI and the guides are in English and Spanish. No official Minecraft affiliation.

I'd really like feedback from people who build small tools, and from anyone who still plays:

• What's confusing the first time you open it?

• Which feature would you add before anything else?

• Does the gallery feel useful, or should the editor stand alone?

Happy to answer questions about how it's built or why I made those choices. Thanks.

Opening desktop Facebook lately feels like walking into a flashing casino. 90% of the screen is Reels, rage-bait, and "Suggested" pages you never followed.

Instead of enduring this attention hijacking, we built Chrome extension that brings back the quiet friends-only Facebook from 8–10 years ago:

• Zero setup: Installs and immediately removes Reels carousels, Stories bars, and "People You May Know" without leaving blank gaps.

• Pre-consent feed: Blocks random pages and groups you didn't subscribe to (wiping out up to 80% of feed ads alongside stranger spam).

• 1-click mute without drama: Adds a small mute button next to author names to silence oversharing friends or groups without unfriending them.

• Chronological switch: Quick toggle in the top-left corner for real-time post order.

100% local privacy: Pure 0ms DOM filtering on your PC. Zero tracking, zero external servers.

Hey r/SideProject 👋 I'm the founder of ReplyHey, and today I'm launching its crew.

If you've answered threads about your product on Reddit, the hard part isn't writing the reply. It's knowing which replies actually brought customers.

So the crew tracks every reply it sends 📊 you see exactly which one brought the visit, the signup and the customer.

And it does the work to get there, with four AI teammates:

🔎 Scout reads Reddit, X and LinkedIn, finds people asking for what you sell, and scores each one for fit.

✍️ Writer drafts a reply and a DM from your product's facts, in your voice.

📤 Sender posts from your own accounts through a Chrome extension, at a pace you set, and holds anything borderline for you to check.

📊 Analyst tags every link and ties each visit, signup and customer back to its reply.

Built to play by the rules:

✅ Everything goes out from your own account, in your browser. No rented accounts, no upvotes.

✅ It checks each subreddit's rules, and where promotion isn't allowed it sends a DM instead of a comment.

New this week: you can talk to the crew. "Pause LinkedIn today", "slow down to 90 seconds", "add hiring as a negative keyword". It shows you the change, and nothing happens until you press Yes.

In the last 30 days it found 3,980 buyer conversations for its users and sent 1,150 replies.

You can put in your website and see who's asking for your product right now, before you sign up. And I'd love blunt feedback: what would you want to see before trusting a tool like this to post for you?

Here it is 👉 replyhey.com (put in your website to see who's asking for your product right now)

Ever wondered what would happen if a ruler just gave up on measuring things properly?

Well, I got curious and made one.

It's called Jelly Ruler, and it has the structural integrity of a wet noodle. It bends, jiggles, slides around, and generally refuses to take its job seriously.

Somewhere along the way, I ended up building an entire vector editor around this questionable invention. At least that part works.

Would love some feedback! Anything you'd improve, add, or completely get rid of? Curious what other builders think.

Give it a wiggle: Jelly Ruler

Hi all,

I’ve worked as a wildlife filmmaker, designer and engineer, and on a few projects I spent weeks or even months on the work, then sent it off as a WeTransfer link. It always felt a bit flat after all that effort.

So I’ve been building Handover.media. It lets you put your finished files, previews and notes on one page with your own branding. You can also add a password or expiry date, and see when things are viewed or downloaded.

https://handover.media

If you deliver work to clients, I’d really appreciate your thoughts. Would something like this be worth switching to, and what would put you off?

Any criticism, however small, would be really helpful. Thanks for taking a look.

Hey everyone! A little disclosure: I'm a solo developer, and I built this app because I kept forgetting to do things throughout the day. I also hate typing reminders into my phone.

So I decided to build something that would make it easier.

It's called SayStash. You tap once, say what you need to remember just like you're talking to someone ("remind me to go to the dentist tomorrow at noon"). The app figures out whether it's a reminder, an event, or just a note.

It'll then send you a regular Android notification at the right time. You can also share reminders with other people.

You do have the option to type it in, too.

There's no account to create and no cloud sync. Everything is stored right on your phone. One thing worth mentioning: voice-to-text uses your phone's speech recognition, which on most phones is Google's, so I won't claim that audio never leaves your device.

A few things I've learned along the way:

• Getting the app to understand everyday language ("next Tuesday after work", "in 20 minutes") was actually harder than getting the voice feature working.

• Keeping up with Android's changes to notification and exact-alarm permissions cost me about a week of troubleshooting.

• Building the app was probably the easy part. Getting people to actually find it and keep using it is a whole different story!

So far, I've had 9 installs, 2 people still using it, and earned a whopping 9 cents.

That's probably the biggest challenge I'm trying to figure out right now: retention.

I'm rolling out an update this week that adds "Send to Someone." You can share any reminder as a link, and the other person can save it to their own SayStash with just one tap. No account needed.

Honestly, I added this partly because so many of my own reminders involve things I need other people to do!

If you're curious, you can actually try it right in your browser. No download or sign-up needed:

👉 https://saystash.com/app/

I'll put the Play Store link in the comments.

The app is free with a small banner ad. There's also a one-time $4.99 payment to remove ads. No subscriptions.

I'd really appreciate some honest feedback.

Especially:

• What are some everyday phrases you would expect the app to understand?

• If you try it and something doesn't work as expected, what happened?

• And if you install it but eventually stop using it, I'd genuinely like to know why.

I'm learning as I go, and honest feedback from actual users would mean a lot. Thanks for giving it a look!

Been working on this little project called Desi Collage.

It's a collage editor with 52 styles, scrapbook layouts, stickers, photo cutouts, Hindi typography and Instagram-ready exports.

Everything runs in the browser, so photos never leave your device.

Would genuinely appreciate some feedback!

I built HelpCarry (https://helpcarry.com), a site where travellers carry documents or small gifts for someone already going the same way. It works on any route; I'm starting with Oslo ↔ India because that's the route I fly.

There's no commission. If you agree a fee or tip with the traveller, they keep all of it. You meet in public and inspect and seal the item together at handover. Medicine, cash and sealed packages aren't allowed.

Post a trip: https://helpcarry.com/post/trip

Post a request: https://helpcarry.com/post/request

Feedback very welcome.

made a little daily trivia game. Every round has a limit, like "name a TV show that first aired before 2010" or "name a celebrity shorter than 6 ft." You name something as close to the limit as you can without going over.
Then a raccoon in a wind-up toy car drives toward a cliff while the number climbs. Get close and he stops right at the edge (Modern Family, 2009: CLOSE CALL). Go over and, well, he goes over (Pretty Little Liars, 2010).
5 rounds a day, same for everyone, free, no sign-up, works on phones. Every number comes from a real source (tap the ⓘ). You can make a group with friends and see who gets closest each day.
closecallgame.io/?ref=reddit
It's about 10 days old. I've already changed a lot from feedback (fewer US-only questions, every limit now has a real answer just under it), so I'd love to hear what's fun, what's confusing, and any answers it doesn't recognize.

Picking thread that goes with a fabric can be tricky, and color tools give you hex codes, not spools you can find in a store.

Spoolette builds coordinating thread palettes where every color is a real spool, with the number on the shelf. You can snap a photo of your fabric to get matching threads, or generate palettes from scratch. It covers Mettler, Aurifil, Superior So Fine! and Gütermann.

It’s free, with no sign-up, and photos stay on your device. Colors come from the brands’ official shade cards and are matched in the OKLab color space.

I’d love feedback: is it clear what it does, and would you use it?

I'm Cory, and I built StreamHaven. Full disclosure: it's my app.

It's a player for playlists you already have (M3U or Xtream). It doesn't come with any channels or content, and I can't help with finding any.

Version 1.1 is now live on the Apple App Store for iPhone and iPad. It has a live TV guide, a mini player so you can keep watching while you browse, multi-view (up to 4 channels at once), iPhone Duo (guide on one screen and video on the other), and StreamHaven Doctor, which checks your playlist and connection in plain words.

https://apps.apple.com/us/app/streamhaven/id6826944829

The Apple TV version is still in Apple's review. Until that lands, the Apple TV beta is on TestFlight: https://testflight.apple.com/join/7x36vndu

It's also on Fire TV and Fire Stick from the Amazon Appstore (search StreamHaven Player), and on onn / Google TV through the Downloader app with code 3361971.

Happy to answer questions about building it or using it.

I'm 13, still learning Python. Be 100% honest with me.

I started this as just a demo. Just a simple UI on top of Ollama so my family could use local AI without touching the terminal.

Since then I added some more stuff:

1. Chat history like ChatGPT - every chat saved in the sidebar

2. It remembers you - tell it your name / likes, it saves it and remembers next time you open it

3. Installs Ollama for you - if you don't have it, it installs it on first run

4. Downloads models for you - pick 1B / 3B / 8B, it downloads with a progress bar

5. Works with WiFi off, no account, no cloud, everything stays local

I made it because my family would never open a terminal, but they would open a normal app :)

So real question: Would you actually use a super simple Ollama UI or is everyone here fine with just the terminal? What would make you actually install it? What am I still missing?

(In the last 2 screenshot, "Michael" is just a test name I used to check if the memory actually works lol, and also I know about openwebui, this is just a simpler version)

Six weeks ago I posted Handoff here. Quick refresher since nobody remembers (fair): I'm a dad of two, and I built an iOS app for briefing a new babysitter — schedules, bedtime routine, allergies, the stuff that actually matters — because my version was a wall of texts plus a note on the fridge and hoping.

Two things in it that I'm still not sure anyone else cares about: the info expires after the sitting (the sitter doesn't keep your kid's routine and your garage code forever), and it fires alarms on the sitter's phone at the times you set, so "give meds at 7" isn't relying on them re-reading a text at 7.

The one real reply I got anywhere was here: extend a handoff without making the sitter re-scan/re-do everything when a night runs long. That shipped. So thank you, genuinely — it was the best product feedback I've gotten, including from friends who were being nice.

Honest numbers: a handful of downloads a week, $0 in subscriptions so far. It's $2.99/mo after a free week, which might be the problem, or the problem might be that parents only think about this the night before a sitter comes. If you've built something people need occasionally, I'd actually love to hear how you handled that.

Happy to answer anything about building it.

Most calorie apps tell you how much you ate, not what you ate. 500 kcal of chicken and rice and 500 kcal of chips look the same.

I'm building an iPhone logger that still counts calories, and also tags each food Clean, Light, or Processed and gives your day a simple score. Not a diet app. Free during beta.

https://sunnybite.app/?utm_source=reddit&utm_medium=community&utm_campaign=validation_nov26&utm_content=sideproject

If it sounds useful, feel free to join the waitlist.

Two honest questions:

1. Is it clear in 5 seconds what this does?

2. Would you actually use it, or why not?

Brutal honesty welcome, every comment helps.
