Turn WhatsApp chats into ready-to-confirm bookings
What it does
Commission-free tour booking software for tour and activity operators who sell direct. Keep taking bookings on WhatsApp, Instagram and Messenger — every booking message turns into a ready-to-confirm pending booking, with automatic reminders and deposits. One flat monthly price, 0% commission.
Commission-free tour and activity booking software for operators who sell direct. Keep taking bookings on WhatsApp, Instagram and Messenger — exactly like you do today. The moment a customer messages to book, it lands in your dashboard as a pending booking, ready to confirm. No copy-paste, no new app for your guests, no commission. Real bookings don't arrive in one tidy message — they're a back-and-forth, with changed dates and afterthoughts. Watch us untangle the whole thread into a single booking, exactly like we do on autopilot. Type a customer message below — or try the easy or messy example. We only read this one chat to show you the result — nothing is saved. Connect your channels…from retveno.com

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy.

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
