Boo.ai is a text editor that uses AI to help you write faster and more accurately with AI-assisted writing. It uses GPT-3 technology to generate copy and make suggestions to improve the style, tone, and structure of writing. It also uses Markdown, a plain text formatting syntax, to help you stay in the writing flow and produce text indistinguishable from human writing. According to the website, it is perfect for copywriting, brainstorming, taking notes, writing emails, and experimenting with AI. It differentiates itself from similar software competitors by offering an AI-assisted writing experience with built-in AI to make writing easier, as well as automatically downgrading to a free plan with limited words per month if not subscribed.
