BrewCat
I built a pour-over coffee tracker that logs your brews, visualizes extraction, and uses AI to suggest your next move. Made it to help myself dial in new beans more methodically - technically it can work with Espresso as well, but I haven't really tested it. Based on my experience, the AI is helpful for identifying direction, but not great with specifics. For example, I often make larger adjustments when dialing in - if I’d normally grind 3 clicks finer on my Comandante, the AI suggests just 1 click or a 1°C temp change. I’m still fine-tuning the prompts, but I think it’s promising for those…

We're two coffee nerds who built an AI app to track beans and recipes2025 · beanbook.app · ▲60It’s available on iOS now: https://itunes.apple.com/app/id6499280064 We got into specialty coffee during COVID and, like many others, fell deep down the rabbit hole. Along the way, we ran into the same frustrations: - A drawer full of empty coffee bags. - No simple way to track grind size, rest dates, notes—by bean. - My coffee history scattered across photos, screenshots, notebooks, and half-memories. - The unique traits, people, and stories behind each coffee disappearing from the internet once it sold out (since coffee is an agricultural good) - In our opinion, no…
Brew Great CoffeeDec 2025 · brewgreat.coffee · ▲142Hi HN! I've been deep in the specialty coffee rabbit hole for a few years and built this tool to help me dial in espresso and pourover more systematically. *What it does:* • Extraction Compass – click where your shot lands (sour/bitter × weak/strong), get diagnosis and adjustments. It factors in your bean's origin, processing method, roast level, and variety. • Pourover recipes from Hoffmann, Rao, Hedrick, Kasuya (4:6) with step-by-step timer. Water amounts auto-calculate based on your dose. • Interactive WCR Flavor Wheel based on the World Coffee Research Sensory Lexicon 2.0.…

Tapflow 2.0▲1,125We built Tapflow for devs, designers, PMs, and tech folks who’ve been sitting on internal docs, templates, and systems — but never productized them. Upload a PDF, notes, or workshop deck, and Tapflow drafts a structured product (with chapters, teaser and pricing plans). It’s good for AI kits, onboarding guides, design systems, and frameworks. You can sell through Stripe, LemonSqueezy, or PayPal. Real-time collaboration is in early beta. No site builder, no LMS — clean design and just focused tools to ship. Fully bootstrapped and just launched on PH today →…
