Spell

What is Spell?

Spell is a browser-based document platform with AI built into the editor. You describe the document you need, such as a proposal, job description, offer letter or essay, and Spell writes a first draft that stays formatted and editable. From there you can revise by typing instructions, highlight a section to rewrite it, regenerate parts you dislike, or edit by hand like in any word processor. Documents can be shared and worked on live with teammates, and exported to Word, PDF or Markdown. The vendor says it uses a model tuned for long-form documents and that customer documents are not used to train its AI. Spell pricing has a free plan with 10 documents and 10k AI credits per month, a Pro plan at $20/month, and a $40/month tier with unlimited AI usage, single sign-on and organizations.

Why use Spell

• Drafting, editing and formatting happen in one editor, so there is no copy-pasting between a chat tool and a word processor.
• You can accept the AI output, ask for changes, or edit manually, so you keep control of the final text.
• Real-time collaboration lets teammates edit the same document and use the AI together.
• The vendor states that your documents are private and are not used to train its AI models.
• A free plan lets you try the editor before paying.
