My friend posts long texts on Instagram, most often they do not fit in 2200 characters. So I created a website for people like her that turns long text into a series of pictures ready to be posted as Post or Story.
I called it Slidable. You paste your text into a text box and see what images will come out. You can choose a format (post or story), change the font size, add a signature with the name of the Instagram profile, and change the colors of the template. Moreover, you can format your text using Markdown and emoji ? text post Instagram
