Hi there thanks for posting in the community! You have two options for quickly adding notes to the canvas. First you can use the Quick Sticky option which is accessible under the sticky note option in the Primary Toolbar. With Quick Sticky you can rapidly type your ideas and press “Enter” on your keyboard automatically creating a sticky note for each idea you type. 

Alternatively you can upload a CSV or TXT file which will create a sticky note for every item in the CSV or each line in the TXT file by selecting the Board Controls hamburger menu > Insert > CSV > Sticky Notes. 

From there, choose the CSV or TXT file from your computer. Once uploaded, Lucidspark will automatically insert sticky notes with each data point in your file. Alternatively, you can simply copy and paste line items in a bulleted list or paragraph.

For more information take a look at this Sticky notes in Lucidspark article.
