What it does
Spell is a document editor with AI built in. You describe the document you want, such as a proposal, memo, cover letter or essay, and it writes a first draft. You can then highlight text and tell it what to change, or edit by hand like in any standard editor. Documents can be shared and edited with others in real time, and exported to Word, PDF and Markdown. It runs in the browser with nothing to install. The site says documents are private and encrypted and are not used to train its AI. Spell positions itself against pasting chat-assistant output into Google Docs or Word, arguing that drafting, editing and formatting in one place gives cleaner results. It says its AI is fine-tuned for long-form document writing.
