This is very standard for most software these days. For some of our developers. English is a second language, and it is easy to misspell words. I understand there are plugins for spelling errors and this request is not geared toward offering correct spelling suggestions but only have a small identifier be visible if there is an error. Once the user is no longer in the element, it should not underline the misspelled word.
Hey @Jason_M_Brown thanks for sharing this feedback! We agree that having some sort of spellcheck would be a nice addition to both Figma and FigJam, and it’s something our team is exploring.
There’s an existing thread about this here:
