I'm working on SPHNX, a voice-based AI coding interviewer. While problem solving is crucial for passing interviews, in a live interview you are also getting tested for your communication, debugging, thinking on the spot, testing, code clarity, and other skills. You can't practice these on leetcode, but it's easy with SPHNX. I've just added rich feedback reports last week that turned out more helpful than I expected.

Right now it works as a mock interviewer for algorithmic (leetcode-style) problems, you can sign up for the waitlist here, I'll send you an invite right after:

https://sphnx.dev

It actually works pretty well, but we're having trouble getting users (some sign up but don't end up doing even a single interview?!).

We're thinking whether we could sell a version of this to companies to do their technical screens in, perhaps with problems that are more similar to the actual software engineering work (e.g. debug existing piece of code, write tests, and extend it).

We're generous with interview credits if you give us good feedback =)

I'm trying a new take on the ubiquitous habit tracker app - one that tracks your daily habits but also tracks rating your day on multiple axes (enthusiasm, engagement, overall mood, etc). The idea is to correlate behaviors and outcomes in a way that provides insight into what could potentially trigger good or bad days. It's also an excuse for me to break out of backend web dev land and learn Vue.js and everything I need to know to actually build and host a web app.

Working on SEO automation agent. For years, understanding and interpreting analytics and combining it with SEO best practices have been a challenge.

We built an agent that can make sense of your website, understand how it renders on search engines, its weak points and strengths. You get actionable advice that can make a huge difference in search visibility, often taking less than an hour to implement changes.

I’m working on a parser + dashboard for bank / cc / investment statements. You feed in your docs and you get a dashboard that shows your categorized “flow” of money (think sankey, stacked bar), as well as some simple grouping tools (Show me all grocery spends on my credit card by month. I initially wrote it in Haskell, but I don’t really know Haskell and I didn’t feel very productive with the stack, so I’m reworking…

Seems like you're not the only one, I've seen other people mentioning similar projects in this post

Yeah I noticed that as well! Makes sense that it’s a pretty “front and center” problem for a lot of people.

An AI powered relationship coach. What started off from, how would and AI relationship coach work if it could see both sides of a relationship, to now having evolved to a full therapy session powered by a small swarm of specialized AI, following integrative therapy principles, messaging integration and more. I've been testing with a small group of friends and am about to launch any day now. If somebody would like to try it, just let me know!

"being a grand dad" is his answer. and he colored it. it's not that deep so as to upset you. darklake just practicing his creative writing.

Colored it a corporate beige. Who the heck is so brain broken as to talk about their grandchild as a startup project and their family as a frigging team. I have to almost need to see this as AI in order to maintain sanity because there’s no way an actual human being talked about a child—their human grandchild like he was a product.

It's clearly a joke. You've never heard people make corporate inspired comments about normal activities? Never had friends talk about sending them a calendar invite for dinner?

I'm working on a tool called Font of Web https://fontofweb.com that helps identify the fonts used on any website. It not only detects the fonts but also shows exactly where they're used (which HTML elements) and how they're styled (weight, line height, size, letter spacing). My goal is to build a comprehensive database of font usage across the web. By collecting and analyzing this data, I believe we can uncover valua…

Nice project! Related question, how would you recommend detecting which font is being used for names like ui-sans-serif, system-ui on a given device/browser?

That's a difficult one, you would need information about the device and operating system to infer the font.

But I imagine, if you realllly needed that info. You could go the hard route and render the font on a canvas, vectorise and perform some sort of nearest neighbour search.

I live next to a school, so there's a low speed limit (30 km/h). Still, people drive like race drivers and the city hasn't ever responded to the residents' hopes of introducing a speed camera. I wanted to have some data on how many people speed, the max speed recorded, that sort of thing. Things the city should be doing after many complaints of dangerous driving and people being almost killed on zebra crossings. I ha…

The guy at Not Just Bikes will tell you that enforcement will never work nor happen and that the only way to get people to slow down is to design the road so it doesn't feel safe to drive fast. The road next to my house has a speed limit of 20mph but most cars go 45mph because it's a straight road 4 lanes but space for 6. No bumps, no curves, wide. Effectively it feels like you should be driving fast. If I go the spe…

This makes sense. Though annoying to drive over, speed bumps work. Also, my parents small town converted their main street from a four lane to a slalom-style two-lane and it so much nicer to walk around because people have to drive slowly. Not quite car-free, which I'd prefer, but it's a decent compromise.

I’m building Videocrawl https://www.videocrawl.dev/ a platform designed to make video content more accessible and actionable. It offers two key features:

1. API for Clean Transcripts – Extract structured transcripts with references, code snippets, and images.

2. AI Video Assistant – Interact with videos using AI-powered tools for summarization, Q&A, and more.

Would love to hear your thoughts! You can reach out to me at sg@o14.ai

Thanks! My idea was to just render a Lorem Ipsum paragraph and compare the calculated width-height across a know list of default fonts. Of course it wouldn't work with fixed width fonts, for that I'd need a canvas bitmap comparison.
