I built a trading journal where an AI coach judges every trade you log. Traders either love it or get offended.

For the last year I've been building TradingSFX , a trading journal for forex/futures/crypto traders. The core idea: most traders don't fail because of their strategy, they fail because they don't follow their own rules. So instead of just storing trades like every journal does, mine acts like a coach. The three things that make people react: Every trade gets an instant verdict . You log a trade, and within seconds the AI tells you something like "this loss was variance, your setup ...

I was drowning in 200 emails a day, so I built an open source AI assistant that cleans my inbox and drafts replies in my voice

for years my inbox was where my day went to die. i run a small saas and was getting around 200 emails a day, support, sales spam, newsletters i never remember signing up for, actual important stuff buried in the middle of it. i once replied to a customer 11 days late because gmail decided the thread was finished. that one stung. tried superhuman, tried sanebox, tried a va for a month. nothing worked, mostly because i didn't trust anything to touch my email without me watching it. so i built ...

I built a home maintenance app that helps you decide what to tackle first

I’ve had HomeQueue live for 2 months now and it is going strong with over 2500 users. It started from a simple problem at home: I had a long list of jobs, but no clear way to decide what actually mattered. A normal task list can remind you to clean gutters, check silicone, replace filters, fix a loose step, book a tradie or sort out the garden, but it still leaves you with the same question: What should I tackle first? HomeQueue is built around that question. It is a web and iOS home m...

Made a stupid app where users can challenge others to do weird & crazy Sidequests. This one is the most completed SideQuest. Should I continue developing the app?

I made an app called SideQuest. Which is available on the web as well. The app allows users to create and challenge others to do crazy and wild Sidequests. Users can complete them, rate and review their experience doing it. Launched last month. People have created 1000+ Sidequests so far. Looks like there's a demand for this and people like this concept. I just made it for fun with no vision on where to take it further. What else can I do to make the app more fun and improvise on this concept...

I built a tool that turns any PDF or image into validated JSON

I kept hitting the same problem: getting structured data out of invoices, receipts, and forms meant either brittle templates that broke the moment a layout changed, or hand-rolling OCR and parsing every single time. So I built Parsara. You define the fields you want once (invoice number, total, ABN, dates, whatever), upload a PDF or image, and get back clean validated JSON with a confidence score on every field. It's API-first, so you can drop it straight into a workflow. It's early, live a ...

I together with chatgpt made a tld checker site.

Yes you read the title right another vibe coded project. https://www.is-it-a-tld.xyz/ I guess I just made this because I myself just wanted something fast to check if a TLD exists rather than having to go on some slow long list or domain registrar. I'm not even gonna explain how to use it because if you can't figure that out you probably need a course in how to use a computer. Just sharing it here incase anyone else needed something like this (probably not) but yeah either way reddit d...

I kept opening my calculator app and notes app back and forth all day.

Calculate something. Copy the answer. Open Notes. Paste it. Go back to Calculator. Repeat. It sounds like a tiny problem until you realize how many times you do it every day. I work in software and constantly need quick calculations for expenses, estimates, percentages, API limits, budgets, and random numbers. My notes ended up full of calculations that made no sense a week later. So I built NoteCalc. It's basically a notepad where every line can be a calculation. Instead of typin...

I built an android app to help children learn the multiplication table

Hi, my wife is a pre-school/elementary school teacher and had an idea to build a mobile application to help children learn the multiplication table(we are from Bulgaria and this is something that 8 years old learn at school). So I built it, it still has stuff to be added and some thing are coming in the pipeline, but the app got approved by google and is now live in google playstore. It is called Smarttimes/Умножител . Any feedback is much appreciated.

built a site where instead of courses you just do real job tasks

I saw a lot of people finishing courses and collecting certificates like it's a pokemon xD. So we built something that bridges the gap between "I finished the course" and "I can do the work" It's called tasklearn.app , you get industry tasks, you attempt them, you see how far you get.. no videos, no tutorial, just the task and ai feedback on that task. Learn things the right way is supposedly harder, but makes you a better developer/designer or whatever you target to be....

I built a sales conversation simulator because I was terrible at sales

I'm a software engineer, and when I started talking to potential customers about software I'd built, I realized I was much less comfortable with sales than development. I wanted a way to practice sales conversations before having them with real prospects, but I couldn't find anything that felt quite right for what I needed. So I ended up building a simulator for myself. What surprised me wasn't whether I could close a deal—it was how many weaknesses I found in my own approach. I would jump...

Would you use a free website that reviews and organizes open-source projects?

I'm validating an idea before spending time building it. The idea is a website that helps developers discover high-quality open-source projects and source code. Instead of just listing GitHub repositories, each project would have: • A detailed review • Screenshots and demos • Feature breakdown • Tech stack information • Setup instructions • Pros and cons • GitHub/source links The goal is to make finding useful projects easier than searching GitHub manually. As a developer, wo...

I'm Alessandro, solo developer based in Italy. Trader by profession, taught myself to code building trading systems. I built Sonic Oracle because I got tired of every streaming app recommending the same stuff. "Similar Artists" on Tidal and Qobuz gives you the same ten names you already know. Radio stations disappear when they're done. Nothing saved, nothing to go back to. So I built something different. Instead of matching what songs sound like, Sonic Oracle maps connections real ...

I built a map to settle where my partner and I should live — by commute time, not distance

My partner and I couldn't agree on where to live. Their job's on the other side of Berlin from mine, and every map measures distance in a straight line, which is useless when what actually matters is how long it takes to get there. Nothing I found accounted for public transport or biking, which is how you actually move around a city. So I built Meet in the Middle . Drop two pins (your job, their job), set how long each of you is willing to commute, and it shades the green zone: everywhere you...

Hey r/SideProject 👋. I built Mizzle based on two ideas: check mail through a feed , and stop using the inbox as storage . Why I built it Honestly, if it were up to me I'd stop using email.

What AI tools have actually become part of your daily workflow?

There are so many AI products launching right now that it’s getting hard to tell which ones are genuinely useful vs just temporary hype. A lot of them look impressive for a few weeks, then completely disappear from people’s routines. I’m more interested in the tools people genuinely use almost every day because they save time, reduce repetitive work, or make life/work easier in a real way. For me lately: ChatGPT for research, writing, brainstorming Cursor for coding/debugging with ai ...
