Byword
Byword is an AI article writer aimed at SEO content produced at scale. It runs a four-stage loop — research keywords, build the article, edit it, optimise it — writes in your brand voice, and publishes to your CMS, with a programmatic mode for generating large sets of pages from structured data.
- Putting research before writing reflects where the actual difficulty in SEO content lies
- Brand voice matching from your existing site produces far more publishable drafts than a tone setting
- Combining research and drafting removes one subscription from a typical stack
- The free articles are enough to judge both research and prose quality on your own category
- You are metered on articles generated, so regenerations and abandoned drafts cost the same as published ones
- Voice matching can disguise thin expertise rather than supply it
- Volume and difficulty figures are modelled estimates, as they are in every SEO tool
