A demo that runs a restaurant waitlist and reservations in the customer’s phone browser — no app install, no sign-up. Try three patterns on sample stores: a waitlist joined by scanning the in-store QR code, with the call-out shown on screen; a time-limited reservation requested before arrival and confirmed by the store, valid for five minutes; and asking an AI assistant such as Claude or ChatGPT to “book a table for three”. The features are published as tools over MCP, so the screens and the AI use the same machinery.

• An in-store QR code that rotates every 30 seconds, so only people on site can join
• Ticket number, parties ahead and estimated wait, with call-outs shown on screen
• Time-limited reservations: arrive within five minutes of the store’s approval
• Check wait times and request, check or cancel reservations from AI assistants such as Claude and ChatGPT (an MCP server is published)
• Staff console (call, approve, seat, undo) and a kiosk screen for the storefront

As a demo, all waitlist and reservation data is reset daily at 4:00 JST. No personal information is collected. The interface is in Japanese.

Enter up to 5 vehicles and 30 delivery stops, and the demo works out which vehicle goes where, and in what order, in a few seconds. It honours arrival windows such as "between 10:00 and 12:00" and inserts a 30-minute break after every 4 hours of driving. Results are shown as road-following routes on a map and as a per-vehicle timeline of driving, service, waiting and breaks.

• Automatic assignment across multiple vehicles and depots, with optimised visit order
• Arrival windows, service time per stop and working hours per vehicle
• Automatic 30-minute breaks after 4 hours of continuous driving
• Road-following routes on a map and a per-vehicle timeline
• Public REST API (POST /api/v1/dispatch/plan)

Limited to the Kanto region. Routing uses the public OSRM demo server; geocoding uses the Geospatial Information Authority of Japan address search API.

Search Japanese addresses from either direction: type a postal code to get the address, or type a town or municipality name to find the postal code. Suggestions appear as you type.

• Postal code to address lookup
• Reverse lookup from town and municipality names
• Public REST API (GET /api/v1/postal-codes/{code})
