As answered by people managing CrossBrowserTesting and It's NUM.
It's NUM's answer:
NUM is built to take the friction out of travel on both sides of a booking and to restore genuine trust to travel information. Travelers tell it what they want, in their own language, and NUM matches their preferences to checked facts and books it. Other assistants can recommend, and some can book, but only through online booking systems and mostly in major languages. NUM standardizes the rest: a website, a LINE chat or a phone call in another language. One tap for the traveler; translated and formatted for the business. Feedback comes from real, verified guests, and nobody can pay to be recommended.
It's NUM's answer:
Travelers who want perfectly matched travel without the research: people planning trips ahead, groups, business travelers, and anyone booking in a country where they don't speak the language, including the many travelers from Asia who already message on LINE. On the other side, local businesses that are hard to find online, often without a website, booking system or ad budget. NUM removes their daily marketing grind and language barrier and sends them high-intent guests through clear, standardized requests in their own language. Developers building AI agents use NUM's MCP server and API for real, checked places.
It's NUM's answer:
NUM began in March 2026, after our founders, Vivian Chan and Andre Darville, returned from a trip to Thailand. It is built around two problems. Travelers face decision fatigue, reviews that are hard to trust, and booking across fragmented, multi-language channels: websites, LINE chats and phone calls. Small local businesses face the daily marketing grind and a language barrier with international guests, and get harder to find as discovery moves to AI. NUM bridges the two with an intelligent matching engine and one standardized booking system, backed by verified facts and crowdsourced nuance. We incorporated as Num AI Inc in California in September 2026 and are bootstrapped.
It's NUM's answer:
NUM runs on Cloudflare Workers with a directory of 2.7M+ places built from OpenStreetMap and owner-claimed listings. Travelers reach it over LINE, SMS and a web app; large language models handle matching and translation across 16 languages. Bookings go through each business's own method: online booking systems where they exist, otherwise calls or LINE messages in the owner's language. AI agents connect through a remote MCP server (OAuth 2.1) and a REST API. The trust layer, which verifies businesses, guests and the reviews they leave, comes from 5arz.
It's NUM's answer:
The end of the five-star guessing game. Instead of hours across apps and reviews you can't trust, you tell NUM what you want and it matches your preferences to checked facts, from dinner to nail appointments and niche dietary spots. Then it books, including the small places other tools can't reach, whatever the language and whatever method the business takes bookings by. Feedback comes only from real, verified guests who booked, so it captures nuance and stays insulated from bot spam and paid placement. It's free for travelers.
