PostNitro is a template-led carousel editor with scheduling to six networks. Mostly starts from your website instead: Moss builds your brand kit, designs each carousel and posts it to TikTok and Instagram.
PostNitro is a solid, cheaper carousel editor, strongest on LinkedIn. Mostly does more of the work: Moss plans, writes and designs from your brand, with AI images on every slide.
Anything in Mostly that isn't fully live yet is labelled Beta, Rolling out or Coming soon.
