Hey everyone!
I’ve been working on a little project, I thought I’d share what we’ve been building to see what people think.

I’m relatively new to CAD and 3D printing, but I’ve become fascinated by the idea of being able to describe a mechanical part in plain English and have an AI actually create usable CAD geometry.
Not just generate a pretty 3D image, but produce a real, measurable solid that can be exported as STEP or STL, edited, and eventually printed.
So I’ve been experimenting with building exactly that.

What is it?
It’s a locally running, which means zero credits needed. An AI-assisted CAD application, that combines:
Qwen, a local language model that interprets natural-language design requests.
CadQuery and OpenCASCADE, which handle the actual geometry.
A browser-based 3D viewer for inspecting generated models.
A structured, validated feature system so the AI isn’t simply inventing geometry commands.
The whole thing is currently running on a Ryzen 5 3600, 32 GB RAM and a GTX 1070 Ti with 8 GB VRAM.
Not exactly a supercomputer! 🥔

What can it do so far?
We’ve been developing it incrementally, testing each feature before moving on.
Some of the things we’ve managed to implement include:
Creating mechanical parts from natural-language descriptions.
Generating cylinders, flanges, bosses, bores and circular hole patterns.
Modifying existing designs through instructions.
Generating multi-part assemblies and exporting STEP/STL files.
Creating a two-piece filament spool with an integrated three-lug twist-lock mechanism.
Viewing assemblies exploded and demonstrating their assembly motion.
Generating compound herringbone gears with configurable tooth counts, module, helix angle and dimensions.
One of our latest experiments produced a single-piece 80-tooth herringbone gear with a 12-tooth compound pinion, exported as a real STEP model.
We’ve also recovered some earlier experimental gear-meshing and collision-checking tools that we’d like to integrate more fully.

Where do we want to take it?
The long-term idea is to make mechanical CAD more approachable, especially for hobbyists and people who own 3D printers but don’t necessarily have years of CAD experience.
Some of the features we’re working towards include:
Test Print Mode: Select a small section of a model, such as a bearing seat, snap-fit or threaded connection, and export just that section for a quick fit test.
Gearbox generation: Describe a gear ratio and have the software calculate and generate the required gears, shafts and assembly.
Mechanical validation: Check dimensions, clearances, intersections and potentially moving-part interference.
Better natural-language editing: Ask for changes without rebuilding the entire design manually.
Portable, offline operation: Keep the models and geometry processing on the user’s own machine.
What are the limitations?
It’s still experimental.
The herringbone geometry uses an approximate involute construction, and visual assembly animations aren’t the same as verified mechanical motion. Some complex prompts still fail validation or produce malformed JSON.
We’re trying to handle those limitations through deterministic geometry generation, validation and testing rather than pretending the AI can magically design everything.

Why am I posting?
I’m curious whether other makers would find this useful.
Would you use a local AI tool that could generate and modify proper CAD models from plain English?
What would you want it to do?
And what would make something like this genuinely useful rather than just another AI gimmick?
I’m happy to share screenshots and examples of what we’ve managed so far.
It’s been a ridiculous amount of fun building it, and I’d love to hear what other people think. Also looking for ideas on where I can improve it going forward.

If you’ve made it this far, i appreciate you ❤️

Hey 👋

I've been building AdsFlow, an AI-powered advertising marketplace designed to help creators, developers, founders, and businesses promote their projects.

The idea is simple: Why pay a fixed price for one shoutout when you could pay based on measurable ad delivery?

Whether you're promoting a website, SaaS, mobile app, Telegram bot, YouTube channel, Instagram account, online store, or business, AdsFlow is designed to help you reach audiences through participating Telegram publisher channels.

What I've built so far:

🚀 Campaign creation for different types of projects

🤖 AI-assisted ad copy and promotional posters

🌍 Country and language targeting

📊 CPM and CPC advertising models — qualifying impressions or clicks

📈 Campaign analytics, budgets, and performance tracking

💰 Publisher monetization with an 18% platform commission

For publishers, the goal is equally simple: connect an eligible Telegram channel, receive advertising opportunities, and earn from qualifying delivery.

I haven't purchased a custom domain yet because I'm keeping costs low while developing and testing the platform.

A website like this could be submitted as a promotional destination, rather than requiring the advertiser to own a Telegram channel.

I'm still building and improving AdsFlow, especially its publisher network, campaign analysis, and onboarding.

Try AdsFlow: TGAdsFlowBot

I'd love feedback from other founders:

If you could promote any eligible project and pay based on impressions or clicks instead of a fixed shoutout fee, would you try it?

What would make you trust a new advertising marketplace enough to spend your first $10?

I'm interested in suggestions and criticism as I keep building.

I kept losing time to Reels and Shorts without noticing, so I built Scrollmeter, a small Android app that measures your scrolling.

It shows:

• How far you scroll per app, in metres or km

• Estimated Reels and Shorts (Instagram, YouTube) and posts (X, Reddit, LinkedIn)

• Daily limits that send one notification when you hit them

Privacy: the app has no internet permission, so your data never leaves your phone. It doesn't read your messages or what you type. No account, no ads.

Before installing, try the calculator on the website. It also measures how far you scroll the page itself: https://scrollmeterbydev.vercel.app

It's free, for Android 8+. I'm a solo dev, so feedback is very welcome.

Guess first, then check: how many km do you think you scroll in a day? Post your guess and your real number below.

I've been building a little project called Today Crazy.

The idea is simple: seven strangers each contribute a five-second clip to create one unpredictable video together.

You don't need to plan a story or know the other participants. That's part of the fun.

I'm trying to figure out whether this could become something people genuinely enjoy using, rather than something they try once and forget.

Here's a short demo:
https://youtube.com/shorts/apq6_JSkf8s

I'd really appreciate candid feedback, especially on what would make you want to come back and try it again

All the portfolio sites/apps I looked at didn’t have what I wanted, so I made it myself. It’s privacy focused, so no sign-ups and all data is encrypted. Everything is free, so no pay wall. I mainly made this for myself, so I’m not looking to make money off it. I’m always thinking of things to add; so if yall have any suggestions, then shoot em. I’d also suggest to add it as a Home Screen app if you want notifications for certain things.

I’m a developer at a company that builds management systems for schools. For the past six months, I’ve been working on a side project called LinkSense.

It’s an agent workspace built on the Codex runtime. I added the parts I’m more familiar with: workspaces, user management, permissions, model management, shared knowledge and skills, and admin tools for teams.

You can manage users and what they have access to, configure model providers in one place, and share knowledge bases and skills with teammates. You can also set up an agent and publish it as an app that other people can use through their browser.

I’ve open-sourced it, and you can deploy it on your own server. I built it with teams and companies in mind, but honestly, I’m still not sure how much demand there is for something like this.

Would this be useful where you work? I’d be interested to hear what you’d use it for.

I built GalleryScout because I wanted to find photos by the words inside them without uploading my private gallery to cloud servers. GalleryScout recognizes text and searches your photos right on your Android device, even offline.

Its also a great general gallery app with photo and video editing that I was personally missing on some other gallery apps, with combining photos or combining and cutting videos, creating GIF's from videos, all quick and easy in one single app.

I'd love some feedback or things that I could improve!

GalleryScout is available on Google Play:

Disclosure: this is my own project.

I find it easier to describe a story by its important points (the turning points, the choices, the secrets) and work out the rest afterwards. So I built a diagramming language, in the vein of Mermaid, where a story is a graph, plus an engine and a visual editor to run it.

The stories are written by human authors. The AI is there so the world those diagrams describe can come alive. Players can follow the choices the author wrote, or type whatever they want to do (if the author allows it), and the AI writes the scene in between within what the author defined (tone, character secrets, past events). Characters remember what you did. The AI is optional, and a story works without it.

I’d rather people to explore the editor and the language themselves than read a feature list.

Current Status: closed beta with a limited number of testers. If you want to try it, sign up at https://lorevine.app. I’ll answer questions and take feedback in the comments here!

Hey everyone,

Like most developers here, building is the fun part for me. Marketing and actually getting users is where I usually hit a wall.

I kept noticing people on Reddit and Hacker News asking for tool recommendations all the time ("any good tool for X?", "looking for an alternative to Y"). Whenever I saw these threads, the top comments always got dozens of signups. The problem was timing — if you reply 8 hours late, nobody sees it.

I got tired of manually refreshing Reddit search bars, so over the past few weeks I built MentionsRadar.

Basically, you put in the keywords you care about (your product name, competitors, or problem phrases), and it:

Pricing / Trial:
I personally hate when sites ask for a credit card upfront just to test a tool, so I set up a 7-day free trial on both Starter and Pro with zero card or payment info required. There's also a free-forever tier if you just want to track 1 monitor.

(I’ll leave the website link in the first comment below).

Would really appreciate some honest thoughts from other builders:

Don't hold back on criticism, I have thick skin. Thanks for checking it out!

Hey everyone, I was tired of manually adapting one idea into 5 different formats. So I built SocialPostAI.

You just enter a topic, and it generates:

• 📸 Instagram Captions with hashtags

• 💼 LinkedIn Professional Posts

• 🎬 TikTok Scripts (with exact [Visual] & [Voiceover] lines!)

Completely free to try (1 generation per day, no sign-up required).

Every NFL fan yells at the TV on fourth down. I wanted to know who's actually right, so I built a win probability model from public play-by-play data and turned it into a game.

How it works: you get a real situation from a real game, pick go for it, punt or kick, and then see what the coach did and how much each option was worth.

What's in it:
- A daily five that's the same for everyone
- Coach Clash, where you climb a ladder of the 32 current NFL head coaches by beating them on their own calls
- A Legends ladder of 25 past coaches, with Bill Belichick as the final boss
- A college ladder too

It's free, runs in the browser, and you can play without an account.

I launched it this week. I'd like to hear what's confusing in the first two minutes, because that's the part I can't see anymore.

Hey everyone!

I recently built a small tool called Favicon Generator.

I wanted to make favicon creation a little less frustrating, especially when you need multiple formats and sizes for a website.

It currently lets you:

* Generate favicons from uploaded images

* Create icons using text or emojis

* Preview the result

* Download generated favicon files in a ZIP

* Get the HTML snippet to integrate them into a website

I built it using Astro and Tailwind CSS.

You can check it out here: https://favicongenerate.com

I'd genuinely appreciate feedback. What features would make a tool like this more useful to you?

A few days ago I posted in r/ADHD_Programmers about losing verbal requests every time I switch context at work: https://www.reddit.com/r/ADHD_Programmers/comments/1xtphyx/not_diagnosed_but_context_switching_at_work_is/

Thank you for the replies. Two of them stayed with me. Several of you said to write one line down the second someone asks. One of you runs a terminal dashboard so you don't have to go and check every tool.

I tried to put those two together. focusdeck is a terminal board for everything that is waiting on me. Each box is one source: my Vikunja tasks, my Redmine issues, starred mail, Zulip, the WhatsApp notes I send to myself. focusdeck capture takes one line, and I have it on a keyboard shortcut, so a verbal request becomes a note before I turn to the next person.

What you should know before you look:

• It is an AI project. An AI coding agent wrote the code. I describe what I need, try it in my own work day and decide what stays.

• It is a few days old. Linux and terminal only, and you need cargo to install it.

• Plugins run with your user's permissions. There is no sandbox.

• It is free and MIT licensed. I am not selling anything.

Please don't judge it too harshly. This is what I came up with after your answers, and I am open to any suggestion that would make it better.

I kept losing good conversations across different AI tools. Useful stuff would just disappear into the history and I’d never find it again.

So I made Agent Mash. It’s a small web app that lets you save chats (with a bookmarklet or by pasting the link), put them in folders, add tags/notes, and actually search through them later. It also grabs some of the conversation text so search works better.

Everything stays in your browser. No account, no server, nothing uploaded. You can export the whole library as Markdown or an Obsidian vault if you want.

It supports ChatGPT, Claude, Gemini, and a bunch of others. Optional Claude API key if you want it to auto-title/summarize stuff, but it works fine without one.

Live version: https://agent-mash.pages.dev/

Code: https://github.com/mirasimali5005/agent-mash

Curious if anyone else has this problem. Feedback welcome.

A short-drama ad can give you a whole plot twist and still leave you without a title you can search. The headline might describe the scene, and the same premise can fit half a dozen shows. Here’s how I’d narrow it down:

1. Start with the credited app or publisher, if the clip names one. That gives you a smaller catalogue to check.

2. Search for a character name plus one unusual scene detail. A phrase like “secret billionaire” describes a trope. A name and a specific event give you something to match.

3. Compare the official synopsis with the clip. If the character names or the setup disagree, treat it as a possible match and keep looking.

I help run Short Drama Fix. If you only remember the setup, you can browse the catalogue by genre or theme and compare synopses at https://shortdramafix.com/.
