Free Genogram Makers Compared

Most "free genogram makers" fall into one of three groups, and knowing which you are looking at saves a lot of wasted effort. There are general diagram tools with a genogram shape library bolted on, family tree software that can approximate a genogram but not really draw one, and a small number of purpose-built genogram tools, usually free only in a limited tier. The differences that matter are not the ones the marketing leads with. This page covers what to actually check before committing hours to a chart, why paper beats software for a first draft, and the privacy question that applies to genograms more than to any other family document. To confirm how two relatives connect before plotting them, use the cousin calculator.

The three kinds of tool

Recognizing which you are dealing with explains most of the frustration people report.

General diagram software — flowchart and whiteboard tools with a genogram shape library added. They draw the shapes, and they usually cannot draw the lines properly: slashed marriage lines, dashed adoption drops and jagged conflict lines are typically absent or have to be faked. Fine for a simple structure, frustrating for a real one.

Family tree software with a genogram export or view. Excellent at descent, dates and sources; weak at the emotional layer, which is the thing that makes a genogram a genogram. Many cannot record relationship quality at all.

Purpose-built genogram tools. Built for the notation, so the symbols and relationship lines are all there. Usually free only in a limited tier — capped at a number of people, or watermarked on export.

Which you need depends on the layer you care about. If you want structure and dates, family tree software is better and the options are covered in free family tree makers. If you want the relationship layer, only the third group really delivers it.

What to check before you commit

The features that decide whether a tool is usable, in order of how often they are the dealbreaker.

Does it draw the relationship lines? Double for close, jagged for conflict, parallel bars for cut off. This is the single most common gap, and it is the whole point of the format.

Does it handle divorce and remarriage properly? One slash for separated, two for divorced, and multiple partnership lines from the same person with children attached to the correct union. A tool that cannot attach children to a specific marriage is not usable for anything but the simplest family.

Can you export without a watermark? Test this early, before you have invested hours. Some tools let you build freely and then charge to get the file out.

Can it produce a legend? Shading is meaningless without one.

Does it support partial fills? Halves and quarters, so one person can carry more than one marked trait.

What are the free-tier limits? Number of people, number of charts, export formats. Three generations of a large family is easily forty people, and low caps bite quickly.

Can you edit later? A genogram gets revised as you learn more. A tool that exports an image but cannot reopen the source is a one-shot.

The privacy question

More serious for genograms than for any other family document, and usually not considered at all.

A genogram routinely contains: mental health information, addiction, medical conditions, estrangements, paternity details, and the identities of living people who have not been asked.

That is sensitive data about third parties, and putting it into a free web tool means putting it on someone else's servers.

Before typing a single name, check: where data is stored, whether charts are private by default, whether anything is used for training or analytics, and whether you can delete an account and its data properly.

Free tools are free for a reason. Sometimes that reason is a paid tier; sometimes it is the data.

Prefer offline or local-file tools for anything containing health or relationship detail about living relatives. A file on your own machine is a materially different proposition from a chart on a service you have not read the terms of.

And think about sharing. A genogram in a family group chat is a document about people who did not consent to being characterised on it. That is worth a moment's thought before hitting send — the worked examples in genogram examples are composites for exactly this reason.

Why paper wins for the first draft

Consistently true, and it surprises people who reach for software first.

Layout is the hard part, not the drawing. Three generations of a real family almost never fit on the first attempt — a large sibling group in the middle generation pushes everything sideways, and second marriages push it further.

Pencil and paper let you find that out in ten minutes. Software makes you commit to a layout and then fight it.

Work in three passes on paper: structure only, then names and dates, then the emotional and medical layer. Doing all three at once is why most attempts get abandoned, whatever the medium.

Then move to software for the version you keep — because that is where software genuinely wins: neatness, editing, and being able to revise the chart in two years without redrawing it.

A large sheet helps. A2 or flipchart paper, or several A4 sheets taped together. Genograms grow sideways faster than expected.

And keep the pencil draft. It usually records decisions and uncertainties the clean version loses. The full building method is in genogram templates.

Feature comparison by tool type

The honest summary: if you need the emotional layer, use a purpose-built tool or paper. If you need lineage and dates, use family tree software. General diagram tools sit awkwardly between the two and are usually chosen because they are already open.

Getting a usable result from a general diagram tool

If a general tool is what you have, these are the workarounds.

Build a stencil first. Draw one of each symbol you will need — plain square, plain circle, double-outlined square, crossed square — and copy them. Far faster than styling each shape individually.

Fake the relationship lines with line styles. Most tools offer dashed and dotted; use those for distant and cut off. For jagged, a zigzag connector or a hand-drawn overlay works.

Use color for the emotional layer and black for structure, which keeps the two readable — but never rely on color alone, since it disappears on a photocopy. Pair every color with a line style.

Lock the structure layer once you are happy with it, so adding relationship lines does not drag people around.

Build the legend as a text box and update it as you go rather than at the end.

Set the page size before you start, not after. Reflowing a finished genogram onto a different page size is miserable.

And export a PDF as well as an image, since PDF keeps the text selectable and prints at proper resolution — which matters if the chart is going on a wall or into a family history book.

Common mistakes choosing a tool

Committing hours before testing export. Check you can get the file out on the free tier first.

Choosing on interface rather than symbol support. A pleasant tool that cannot draw a divorce line is not a genogram tool.

Using family tree software and expecting the emotional layer. Most cannot record it at all.

Not reading the privacy terms before entering health information about living relatives.

Starting in software. Draft the layout on paper.

Ignoring the free-tier person cap until you hit it mid-chart.

Relying on color alone for the relationship layer.

Forgetting the legend, which makes shading meaningless.

And choosing a genogram tool when what you needed was a family tree — if the question is lineage and dates rather than relationship quality, printable family tree and the format comparison in family tree chart types will serve you better. Blended structures in particular are often clearer on a tree with a household grouping, covered in blended family tree template.

FAQ

What is the best free genogram maker?

It depends what you need. Purpose-built genogram tools handle the symbols and relationship lines properly but usually cap the free tier; family tree software is better for lineage and dates; general diagram tools work only for simple structures.

Can I make a genogram in general diagram software?

For a simple family, yes — build a stencil of the symbols and use line styles for the relationship layer. It becomes frustrating with divorces, remarriages and blended households, where the specific line conventions are hard to fake.

Do family tree programs make genograms?

Some export a genogram-style view, and they handle descent, dates and sources far better than genogram tools. What they usually cannot do is record the emotional layer, which is the point of a genogram.

Is it safe to build a genogram online?

Check where the data is stored first. Genograms routinely contain health, mental-health and relationship information about living people, so a local-file or offline tool is a safer choice than a free web service whose terms you have not read.

Should I use software or paper?

Paper for the first draft, because layout is the hard part and pencil lets you redo it in minutes. Software for the version you keep, because editing and revising later is where it genuinely wins.

What is the most important feature to check?

Whether it draws relationship lines — double for close, jagged for conflict, parallel bars for estrangement. That layer is what makes a genogram different from a family tree, and it is the commonest thing missing.

Check the lines, not the interface

Genogram tools divide into general diagram software, family tree programs and purpose-built genogram apps, and the deciding feature is almost always the same one: can it draw the emotional relationship lines. After that, test export on the free tier before investing hours, and read the privacy terms before entering health or estrangement detail about living relatives — a genogram is a more sensitive document than most people treat it as. Draft on paper first whatever you choose, because layout is what takes the time. And to name a relationship before you plot it, use the cousin calculator.
