Most of the text fields in SciNote (task description, protocol step description, etc.) have a limitation of 100,000 characters.
If you need to input a lot more text than allowed, we propose you break down the content between multiple protocol steps. You can create as many steps as you wish.
The other option is to simply upload the Word or PDF file under the Results tab within a task or under the Files tab within an individual protocol step (see the image below).
