Boo is a new kind of text editor, that uses AI to generate copy, make suggestions, and help you brainstorm — all in a simple text editor interface.

Boo uses a technology called GPT-3 for content generation. GPT-3 is a language model that can generate text based on natural language prompts. It’s trained on a huge dataset of text, and can write text that is indistinguishable from human writing.

Every plan comes with a 3-day free trial, with no credit card required. At any time during your trial, you can choose to subscribe to Boo starting at $8/month.

If you decide not to subscribe to Boo during your trial, you will automatically be downgrade to the Free plan, which is limited to 2,000 words per month.
You can upgrade to a paid plan at any time.

Boo uses Markdown, a simple plain text formatting syntax to help you stay in the writing flow.

Jasper is a similar product that uses GPT-3 to generate copy. Boo is designed to be faster and simpler. In addition to being a great app for copywriting, Boo is also perfect for brainstorming, taking notes, writing emails, or just experimenting with AI.

“I have been experimenting with different AI services over the last few days; Grammarly, Writesonic, Jasper, etc and NONE of them have come close to how easy your program is to use.”
