You can create a free Lexchart account. There are just two steps:
Step 1. Register for the free 14-day trial
The trial will give you access to all Lexchart features. There is no credit card required.
Step 2. Let subscription convert automatically
When your free trial expires, your account will automatically convert to a free account. You can upgrade to a paid plan anytime.
There are three import limitations to a free account. First, you have access to one chart. Second, there is no storage available. When you log out, the chart is deleted. You can, however, download your chart and keep that file. Third, the import feature is only available on a paid subscription.
