Spent 6 months building an app that reads your contracts — discovered I'd been paying for 3 subscriptions I'd completely forgotten about The original problem was simple: I'd missed a lease auto-renewal and got stuck for another year. I wanted something that reads your documents and tells you what to watch for. Six months later I had Goffer (goffer.ai). But the real test was dogfooding it — loading all my own documents to see what the app found. It flagged two subscription auto-renewals I'

I've been working on https://notebooker.ai if anyone is interested in giving some feedback. I tried to post a Show HN yesterday with details about how I built it, but was auto-flagged and not sure what rules I broke. Everything that I've built on top of open-notebook, like the plugin system for your own "creators" (aka, podcasts, infographics, etc) is at https://github.com/Notebooker-ai plus a Cloudflare Worker AI deployer to play with different models. Been working on it for about six months.

I made Slick, the World's Most Customizable Search Engine For the past year, I've been building Slick , an independent search engine focused on privacy, speed, and giving users much more control over how search works. One thing that has always bothered me about modern search engines is that they expect everyone to search the same way. Whether it's AI overviews, ranking decisions, or the layout of the results page, you're usually stuck with whatever the search engine decides is best. I wa

Just shipped my first web app ever. For years I’ve been tracking all my stocks and crypto across different platforms in a messy Excel file. Soon I’ll finally be able to replace it with this: → Built entirely with @grok Build. It’s designed for people in the European Union. Fully centered around the euro, and it properly accounts for the currency effect on dollar cash positions. Clean interface, works great already, and I did a proper security check before putting it online. There might be a few small bugs but I’m genuinely proud of how far it already is. And this is only the beginning. Burned through my weekly Grok limit + topped up credits three times to get here. Limit resets on Tuesday... then we continue.

THEY JUST GAVE AWAY 100 MILLION FREE TOKENS SO YOU CAN STOP BURNING THROUGH YOUR CLAUDE CODE BUDGET. if you code with AI you already know: the session fills up, starts failing, and on top of that you're overpaying there's a tool that fixes this: it shrinks the context before the model even sees it same model, same response, a fraction of the cost in a real session: from $154 to $43. a 72% drop and right now: → extend your Fable sessions in Claude Code → 100M free tokens to try it out you don't switch models you don't touch your code you just stop paying to repeat yourself link below ⬇️
