WhoIsWho for WeChat

Thousands of contacts, one sentence to recall who knows what and how to reach them

Problem

Once a WeChat contact list hits thousands, finding someone who knows a given field means keyword-guessing or asking around in group chats. Adding contacts is cheap, but remembering each person's industry, role and expertise is expensive, so weak ties are worthless exactly when you need them.

Solution

A lightweight relationship notebook: quickly tag people (industry, skills, company, ways they can help, last contact), search in natural language like "someone in Beijing who knows data compliance", and get nudged about dormant ties. Data stored locally.

Users

Salespeople, founders, active networkers, freelancers

MVP

Fast entry with tag templates; multi-keyword and natural-language search; dormant-contact reminders; export and backup; import from contact notes

Revenue

Free up to 200 contacts, subscription for unlimited contacts and reminder rules; separate license for a lightweight team/CRM import tool

Why now

Natural-language search is now cheap to build, and WeChat has no good personal network-search tool; a solo dev can validate fast
