Use it every day

Honestly didn't expect to like it this much. Preset characters, animals, and objects is exactly what I needed, and supports metric and imperial units. I do wish visual style may feel basic for pro design work, but I reach for it almost every day now and it just clicks.

Does the job

Pretty happy overall. Color and label customization just works and large library of presets and silhouettes. Primarily focused on height only can be annoying, but no dealbreakers — I'd recommend it to a friend without hesitating.

Solid for our team

We rolled this out across the team last quarter and quick, no-signup chart creation. Custom subjects with adjustable heights fits neatly into how we already work, and shareable and downloadable outputs removed a step we used to do by hand. Visual style may feel basic for pro design work, which is the main caveat, but it has held up under daily use.

Years in this space

I've evaluated a lot of these over the years. What stands out here is color and label customization — handled better than most — and easy to share or export visuals. Visual style may feel basic for pro design work is my one real gripe. Worth the time if this is your use case.
