What is Spell?
Spell is a document platform built around AI, combining a real-time collaborative editor with a writing assistant. You describe the document you want in natural language, and Spell produces a first draft in seconds, with formatting already applied. You can then refine it by talking to the built-in editor, editing manually, and sharing the file with others for real-time collaboration.
The platform is aimed at business and academic documents: business plans, job descriptions, proposals, financial reports, NDAs, letters of intent, research papers, essays and personal statements. The site also lists guided templates such as client proposals, offer letters, SAFE agreements and ESG policies. The company states that documents are private, encrypted, and not used to train its AI models.
