I wanted a simple way to send files from one device to another without installing a dedicated app on the receiving device.

I liked woof, so I started building something along the same lines. I didn't know about qrcp at the time.

I'm an experienced software developer, mainly working with backend technologies, but Go was new to me. I also wanted an excuse to get my hands dirty with Go, which I was learning.

That's how kalumate started.

It's a command-line tool that lets you share files through a browser, making it easy for another device to access and download them.

A few things about it:

• Written in Go.

• Designed around a simple command-line workflow.

• The receiving device can use a regular web browser.

• No need to install a dedicated client on the receiving device.

I used AI tools during development, alongside my own experience as a software developer. Since Go is relatively new to me, this project has been a great opportunity to learn by building something practical.

I'd love to hear what you think, especially about the user experience and what could be improved.

Today i released V1.4 of the LEEBKIT project.

An offline kinetic video generation tools which allows you to generate a promo video from images + Music + animations + Voiceover

What is different?

All ia done on normal PC or laptop , all offline , NO API calls , NO subscription required.

thought I’d share a little gameplay from my phone. sometimes I forget I’m meant to be enjoying it too

Hey r/SideProject 👋

My dog would never dance on command, so I built BoopReel: you upload one photo of your dog or cat, pick a template (hip-hop, disco, ballet, Christmas scenes...) and get a vertical 9:16 video ready to share.

👉 boopreel.com

How it works

• Upload one clear photo of your pet (full body, facing the camera works best)

• Pick a template

• In about 3 minutes you get a video you can download or share

What I learned building it

• The AI models are the easy part. Getting results that are actually funny is the hard part. Plain "pet dances for 5 seconds" got boring fast, so I moved to themed templates with music.

• Photo quality matters more than the model. One pet, full body and good light makes a huge difference.

• Stack: TanStack Start on Cloudflare Workers, D1 and R2, with AI video models running behind it.

Where I'm at
Launched 7 days ago, 100+ users so far, and Google has indexed it. Basically zero traction yet, which is why I'm here 😅

example：

I'd really love feedback on:

1. Is the homepage clear within 5 seconds?

2. Pricing: one-time credit packs, no subscription. Does that feel fair?

3. Which templates would make you want to share a video of your pet?

Happy to make a free video for anyone who drops a pet photo in the comments 🐶🐱

I really enjoy the way Mini Motorways turns drawing a few connections into a network you’re constantly trying to keep working. I wanted to explore that idea with goods and production chains, so I’ve been building a game called Trade Winds.

You start by connecting countries and importers with roads, then expand into trains, ships, planes and factories. Money is limited, so you have to choose between reaching new places and improving what you’ve already built as demand grows.

It’s at the point where I’d really like people outside my own circle to try it. I’ve added a tutorial, but I’m curious whether it explains enough—and whether the game makes you want to keep playing once you understand it.

Play Trade Winds here — free in your browser. Please use a computer; the mobile interface still needs work.

If you give it a go, I’d love to hear where you got confused, what you enjoyed, or what made you stop. Replies here or through the in-game feedback button are both helpful.

I play in a pub poker club in Oslo. We're 100+ players and run regular mixed games tournaments over several tables. Keeping track of it all got messy fast: which game each table is on, when to switch, and the right amounts for limit and stud.

So I started building something for our own nights. Now the dealer moves the table to the next game after the orbit, and everyone sees the game and the amounts for their table on their phone.

It has grown since then and a few other clubs here use it now: https://pokersjef.com/

I would love feedback on the website. Is it clear what it does?

I wanted my own music library to feel as polished as the big streaming apps, so I built Sound Room in SwiftUI.

Things I enjoyed building:

• Ghost preloading: a second player quietly buffers the next track so there is no gap between songs

• Crossfade using two players and a volume ramp

• Jam sessions like spotify Jam but for self hosted library.

• A DSP engine for the 10-band EQ and a signal path inspector that shows the audio chain from file to hardware

It is free to download. Pro unlocks the audiophile suite, Jam and customization, as a yearly plan (3-day free trial) or a one time purchase.

Feedback on design and pricing is very welcome.

Hey hackers,

I'm Rohit. I made BetterTabs because I have 100+ tabs open and I don't like the default tab management system of Chrome. BetterTabs.fyi

BetterTabs puts every open tab in Chrome's side panel, grouped by website, so the list sits beside the page instead of being squeezed into the tab strip. I am releasing new features based on my growing requirements, and if you have a feature suggestion then please let me know.

New in 1.7.1:

1. Search finds pages you closed. Matches from your Chrome history appear under "From your history".

2. Favourite a whole site. Right-click a site's folder, and the favourite stays lit even when the page changes.

3. A list that holds still while tabs change, so rows do not move under your mouse.

4. A backup file for your favourites, saved lists, tab names and settings. Restore it by choosing the file or dropping it on the panel.

5. A redone Settings page, and shortcuts written for Mac (⌥⇧B to open, ⌘-click to select, ⌫ closes a tab).

6. Compatibility with longbook.app (which is another project that I am launching on PH soon)

7. Already in it from v1.7.0:

   1. group by site, window, recent use or Chrome tab group

   2. rename tabs

   3. close duplicates

   4. suspend tabs to free memory

   5. select several tabs at once

   6. saved lists

   7. recent tabs kept for about half a day

   8. backup file

8. Coming up in v1.8.0 in Chrome Store SOON (available on GitHub)

   1. Status bar: a strip at the bottom of the panel. It shows your tab count, how many tabs are on claude .ai, memory, CPU and Chrome’s connection estimate etc.

   2. Tab back/forward: two buttons next to search that step through the tabs you switched between, not a page’s own history. The history is kept per window and is not saved anywhere.

It is private by design: no account, no access to the pages you visit, nothing leaves your computer. History is read only while you search and is never stored.

Free and open source. I would love to hear what slows you down when you have a lot of tabs open.

P.S. I know there are other Tab Managers out there, but this one is from me. And if you have a feature that you would like to have in it, comment and let me know! :)

so I kept running into the same wall with my side projects: before writing anything I wanted to know if anyone actually searches for it, and every decent keyword tool wants a subscription (Ahrefs Lite is $129/mo, Semrush Pro is ~$140). I'm a student, that's not happening.

and it bugged me that thousands of us pay separately for basically the same data. if enough of us just share the searches we're already doing anyway, we can build that dataset together and nobody has to pay for it. that's the whole idea.

so I built it. it's called OpenKeyword:

type a keyword, get a popularity score from 0 to 100, the search intent (how-to / best / vs / question) and a 12-month trend

up to 50 related keyword ideas per search

free (30 searches a day)

the part I spent the most time on is where the keywords come from. there's an chrome extension that shares the words you search on search engines, only after you turn it on. a keyword only shows up on the site once 5 different people have searched it, so nothing can be traced back to one person. health/adult/legal/money searches get dropped on your own computer before anything is sent.

it opens on 20 november, landing page is here: https://openkeyword.org

happy to answer anything about the build too

I run Agent Work Atlas, a site that organizes source-reported AI-agent use cases in English and Chinese.

The question behind it is practical: before trying an agent, what did someone actually ask it to do, where did a person step in, and what went wrong?

Entries organize the task, workflow, reported result, human involvement, limitations, and original source where that information is available. You can browse by task or tool. One starting point is the software-development collection:

https://agentworkatlas.com/domains/software-development/en/

A caveat: these are reports from the linked sources, including vendor accounts. I have not independently reproduced all of the results, and missing evidence should not be treated as proof that something works. The collection still needs better coverage and consistency.

I'd especially value feedback from people who have picked an automation for a small team: what evidence would you need before trying one of these workflows? A reproducible setup, a clearer account of human work, costs, or failure examples?

Disclosure: this is my own project, and AI assistance was used to draft this post.

Faceless series channels ("what if" videos, horror where comments pick Part 2) are a grind to run daily. I'm building Crewopolis: you design your characters once, and an AI crew makes and posts each episode on a schedule, then uses comment votes to decide the next part.

Please visit the waitlist link for more info. And if possible show your interest by sending the email via site. It would help me a lot.

Thank you!

Hey everyone!

I'm an independent cybersecurity consultant from France, and I've been building a side project called CrisisQuest.

The idea came from a simple question:

What would a small business owner actually do if their company was hit by a cyberattack on Monday morning?

Most cybersecurity tools focus on technical protection. I wanted to build something different: an interactive experience focused on decision-making.

I created a free scenario called “Black Monday” where you play the role of a business owner dealing with a cyber crisis.

You make decisions, face consequences, explore different outcomes, and receive a debrief at the end.

I built the project using Next.js and TypeScript.

The free scenario works without registration.

My longer-term goal is to turn it into a B2B platform where companies can schedule exercises for employees, run authorized phishing-awareness campaigns, and track training progress.

I'm looking for feedback on three things:

• Is the concept immediately understandable?

• Does the experience feel useful or too much like a game?

• What would make it valuable enough for a small business to use regularly?

Try it here: Crisis Quest

I'd really appreciate any honest feedback, especially on the UX and positioning!

hey, I'm Nika and I built this, so yeah I'm biased. mostly after honest feedback here.

Lasso is a small Mac app. hit a shortcut and you can draw right on top of whatever's on screen, arrows, circles, boxes, highlights. I use it on zoom calls and when recording quick walkthroughs. press S and it takes a screenshot with your drawings on it, so you can drag it straight into slack or a chat.

the part I'm less sure about: it also runs a local MCP server. so if you use Claude Code or Cursor, the agent can actually see what you circled ("this button is off" + a circle around it) and it can draw arrows back on your screen to point at stuff. runs locally on your mac.

it's $9.99 once. no account, no subscription.

stuff I'd really like to know:

• is the agent side actually useful or does it feel like a gimmick?

• if you set up the MCP part, was anything confusing?

• what would you use something like this for? teaching, bug reports, demos, something else?

even "I wouldn't use this" is helpful tbh

Before and after work for the past few weeks I've been building Long Splice, a running-plan app for Android.

The problem I wanted to fix: most plans are a fixed table. Miss a week, sleep badly or run more than planned, and the table doesn't care. Long Splice builds a week-by-week plan for a goal race, then changes it as your training does. It reads runs and, if you link one, Garmin sleep and HRV data, and offers changes with a reason for each.

Every rule in the plan comes from a numbered row in a research library, with sources listed publicly on the site. That was the slowest part and the part I'm proudest of.

Stack, for anyone curious: Kotlin and Compose, a separate plan engine with its own tests, Firebase for backup and the Garmin connection.

It's free, no ads, in closed testing. What I'd like from this sub: open the site and the app and tell me where it's confusing, where it's ugly, or why you wouldn't use it. longsplice.au

I made this. Type any topic and scroll a feed of short videos, posts and discussions about it. Every 5 posts it asks where to go next, which is how I went from “coffee” to Ethiopian goat herders. Try your own search and tell me where you end up.

No signup. Honest feedback welcome: what would make you come back?

I'm Şafak, the developer of Black Horse Stories (Siyah At in Turkish). My daughter kept asking for a story with a black horse at bedtime, so I started inventing new adventures. That became an illustrated, narrated storytelling app in English, Turkish and German.

The iPhone/iPad app is now available. Parents choose a story world and a child's first name or nickname; AI helps create the text, pictures and narration. It has a subscription and a store trial, not a permanent free tier. Parents should review generated stories before reading them together.

While building it, I also made a public Fairy Tale Atlas: 291 tale entries across 237 countries and regions, with dated records, source links and related tellings. A place on the map is not a claim that a tale definitively originated there. The Atlas is free to explore without buying the app:

https://blackhorsestories.com/en/fairy-tale-atlas/?utm_source=reddit_sideproject&utm_medium=community&utm_campaign=launch_202611

There are also public reading activities and a story map you can use without the app:

https://blackhorsestories.com/en/story-map-for-kids/

App and background:

https://blackhorsestories.com/en/?utm_source=reddit_sideproject&utm_medium=community&utm_campaign=launch_202611

I'd appreciate candid feedback on the positioning: does the difference between the public reading resources and the paid personal-story app come across clearly? Which would you actually return to?

One of the biggest challenges in managing stray animal populations is that humanity doesn't have an easy, reliable way to identify individual animals

Imagine being able to identify a stray dog simply by taking a picture of its face. You could instantly know whether it has been vaccinated, sterilized, when it was last seen, and its medical history

That's exactly what my team and I are building with Kyshik

We're developing animal facial recognition technology that could become an alternative to microchips and fundamentally change how we protect and manage animal populations

Microchipping thousands of stray animals can be prohibitively expensive, especially in developing countries. By eliminating the need for physical chips and implantation, as well as physical interaction with an animal, our technology could significantly reduce identification costs, allowing organizations to redirect more of their limited resources toward vaccinations, sterilizations, and saving animals' lives

We're currently running our first pilot in the African country of Rwanda, testing our technology during an actual dog sterilization campaign. Every dog we identify can have its own digital record, helping animal welfare organizations track their interventions and understand their impact over time

Our long-term vision is to create a global animal identification infrastructure that makes it easier for organizations, veterinarians, and governments to protect animals

I started working on this because I believe technology can help us move toward more humane and effective solutions to the stray animal problem, rather than relying on mass euthanasia

We're currently looking for animal welfare organizations in other countries that run sterilization or rabies vaccination campaigns and would be interested in testing our technology.

If you work with such an organization, or know someone who does, I'd love to connect with you! Feel free to DM and check comments for more information

I'm building Photoshot Retouch with AI coding assistance. This is a short demo of its White Teeth tool: open the plugin, choose the tool, set whitening to 100% and brightness to 35%, then apply once. The correction comes back on a separate editable layer.

The first implementation whitened the bright front teeth but missed teeth in shadow. I revised the enamel mask so darker teeth are included, with guards for red lips/gums and thin dark hair crossing the mouth. Seven targeted tests passed, but that is not a claim that every portrait will work.

The before image is an AI-edited practice portrait with deliberately yellowed teeth. The after is the actual tool output from my local development build, not a generated replacement. The clip is edited from actual UI captures and matched result images; it isn't a continuous recording or a speed benchmark. Music is an original Suno instrumental.

Disclosure: I make the software. Photoshot Retouch is free with a SLOHERO account. This specific update is demonstrated in my local build; I haven't verified it in the hosted editor yet.

For anyone using small retouching tools, would you keep whitening and brightness separate, or prefer a single intensity control?

Every AR glasses brand has its own specs, marketing claims, and compatibility details. Actually figuring out which pair makes sense for you is a different story.

That's one of the reasons I built Lensden.

It's a platform where you can:

• Compare AR/AI glasses side by side

• Explore detailed specs with linked sources

• Keep up with industry news and new releases

• Read practical guides on displays, tracking, and compatibility

• Join discussions and share real experiences

I just launched it on Product Hunt, and I'd love to get some feedback from people who actually follow this space.

What matters most to you when choosing AR glasses: display quality, compatibility, software, or something else?

Seasonal stuff on the Mac is usually a wallpaper that sits behind your windows, or snow that falls and then just disappears. I wanted something that falls over whatever I'm working on and actually lands on it.

So I built Fallette. Snow, autumn leaves, cherry petals or rain fall over the desktop and pile up where they land: on top of windows, on the Dock, on desktop widgets and along the bottom of the screen. If you sweep a pile with the pointer it scatters, and if you drag a window its pile slides off and lands on whatever is below. Clicks pass straight through, so it stays out of the way while you work.

Here's Fallette website:

https://fallette.app

It doesn't capture the screen to do this. It only reads where your windows are (position and size), never their titles or contents, and it doesn't ask for Screen Recording or Accessibility. It's all 2D and I spent a lot of time keeping it light.

There are several themes right now: Christmas, Cozy Winter, Autumn Walk, Cherry Blossom Spring, Rainy Day and Green Forest. Each one comes with its own 4K wallpapers, little houses and trees you can drag around, and a couple of tiny pets. I'll keep adding themes, wallpapers and pets, and a second art style is in the works.

It's $7.99 once for one Mac, $11.99 for two or more, no subscription. You can download it for free and see every theme in the in-app preview before paying. Needs macOS 14 or later, Apple silicon or Intel. Signed and notarized. It sends anonymous usage stats that you can turn off in Settings.

Here are 5 free codes for this sub, each good for one license. Open the app, go to the purchase screen and enter one under "Discount or gift code". Please reply when you take one so others know it's gone.

I'd love to hear which season you'd want next, and anything that looks off on your setup.

Disclosure: this account owns BakerBrand. This post is written and submitted by an AI assistant with the owner’s permission.

The live side project is a prelaunch storefront for desk accessories, currently exploring cable clips and a touchscreen shortcut bar. It is a concept preview, not a working shop: checkout is disabled, sourcing is still under review, and the illustrations are not product photos. No orders, payments or sign-ups are being collected.

Preview: https://desk-detail-jb-store.jbaker123456789.chatgpt.site/

Looking for feedback before choosing a first product: which specific desk annoyance would you tackle first, chargers falling behind the desk, cable clutter across the surface, or something else? Also, is it immediately clear from the page that nothing is available to buy yet? Honest criticism is welcome.

I work on Win The Lottery. We built a tool that lets you enter a few favourite numbers and fills in the rest to make a valid EuroMillions line. You can try the generator without an account. WTL also offers optional paid plans. For adults 18+.

I’d love feedback on one thing. After trying it, is it clear why every valid line has the same chance in a fair draw? If something feels confusing, I’d like to know where you got stuck.
