Getting words down
HyperWrite
A browser assistant for rewriting sentences and producing short drafts in the page you are already on. It is built for emails, posts, and articles more than for an 80,000-word novel. Fine as a line-level spare, not as the place you keep the book.
Best for
Short-form drafts and quick rewrites, especially outside a dedicated writing app.
Pricing
Freemium. Free tier with a tight daily cap. Paid plans raise the number of rewrites and suggestions.
