HighFive

This is a prototype of a conversation app. It can help the user choose the right medical marijuana for his problems, it can help obtain a medical marijuana card, it lets them buy the best solution to their problems, it will process payments, etc.

Back in 2017, this was built on:

• api.ai / Dialogflow API — an early language-processing AI, quite long before the current LLM era
• Contentful API — the "back office" for the inventory
• Framework7 — a mobile UI framework for the native iOS look & feel (still powering it today)

📱 On iPhone, open this page in Safari and tap Share → "Add to Home Screen" to install it as a full-screen app.

Created by Josef Richter back in 2017, using the emerging AI technology of that era — recovered and revived in 2026 with Claude.
