How to map your personal network

Updated July 11, 2026

Mapping your personal network means laying out the people you know as a visual graph – each person a node, each relationship a line – so you can finally see the shape of your world: who connects to whom, which ties are strong, who introduced you to whom, and where the quiet gaps are. This is a guide to doing that honestly, without ending up in a flowchart tool.

Why map it at all

You already hold a version of this map in your head, and it's lossy. You forget which two friends would hit it off, lose track of the person who could open a door, and can't see that a whole slice of your professional life hangs off one introduction. A network on a screen makes the invisible legible: the structure of your relationships becomes something you can look at, not just something you vaguely feel.

The trap is reaching for the wrong kind of tool. Ask the internet how to map your network and you'll be pointed at flowchart editors and mind-mappers – tools that make you drawa picture that's stale the moment you close it. The better question is which kind of tool actually fits the job.

Four kinds of tools people reach for

1. Freehand diagram editors – draw.io / diagrams.net and friends. You place boxes and draw arrows by hand. Fine for a one-off picture on a slide; useless as a living map, because the tool holds no data about the people and every change is manual redrawing.

2. Mind-mappers– XMind, MindNode, and the like. Built for branching ideas out from a center, not for the messy, many-to-many web of real relationships. A network isn't a tree.

3. General knowledge graphs – TheBrain, Obsidian's graph view. Powerful and genuinely local, but every node is generic: a person, a file, and an idea are the same kind of object, joined by unlabeled links. You can build a people map in them, but you have to design it yourself, and it can't express warmth, introductions, or a face.

4. Analyst tools – Kumu and other social-network-analysis platforms. Superb for research-grade work (centrality metrics, community detection) on public, cloud-hosted maps – overkill, and the wrong privacy model, for quietly mapping your own life.

Where Handshake fits

Handshake is the tool for the specific case the others generalize past: a private map of the people you know. It's a free, open-source desktop app (macOS, Windows, Linux) that puts you at the center of a spatial board and fans your network out around you – each person a card with a face, each relationship a line whose weight is the warmthof the tie. It draws introduction chains, links people as you mention them in notes, and lets you pin goals near the people who can help. And because it's all plain markdown files on your machine, the map is yours the way a folder of documents is yours.

It is not a general second brain – if you want ideas, files, and people tangled in one graph, TheBrainis the honest pick. It's not a research platform, and it has no mobile app yet. What it is: the one tool on this page that treats your network as a network of people, and hands you the map in two minutes instead of a blank canvas. If you're also thinking about remembering and keeping up with those people, the sibling to this guide is what a personal CRM actually is.

Questions

What does it mean to map your personal network?

Mapping your personal network means laying out the people you know as a visual graph – each person a node, each relationship a connection – so you can see the shape of your world: who connects to whom, which ties are strong, and where the gaps are. It turns a mental address book into something you can actually look at and think with.

What is the best tool to map relationships between people?

It depends what you want. For a private, purpose-built map of the people you know, Handshake is a free local-first desktop app that models warmth, introductions, and notes as plain files. For general idea-and-people graphs there's TheBrain; for research-grade network analysis there's Kumu; for freehand diagrams, diagrams.net. Only Handshake is built specifically around personal relationships.

Can I map my network without a flowchart or diagram tool?

Yes – and you usually should. Diagram editors like diagrams.net make you draw and re-draw boxes by hand, and they hold no data about the people. A purpose-built tool like Handshake keeps the people as real records (with notes, roles, and tie strength) and draws the map for you, so it stays live instead of becoming a stale picture.

Is there a free relationship mapping app?

Handshake is free and open source, storing your network as plain markdown files on your machine. TheBrain has a free tier, Kumu is free for public projects, and diagrams.net is free – but among these, Handshake is the one designed specifically for mapping personal relationships privately.
