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
SEO.AI
SEO.AI, based in Kongens Lyngby, Denmark, is an SEO agent that creates content, publishes it directly to your CMS, and builds backlinks through an automatic link exchange network. It supports 50+ languages and integrates with WordPress, Webflow, Wix, Squarespace, Shopify and Magento.
- Three approval modes mean autopilot is a choice rather than the only option
- Email notification before publishing is a sensible safeguard
- 50+ languages makes localised SEO affordable for the first time for many businesses
- Shopify and Magento support targets product copy, which suits generation far better than blogs
- Fully automatic publishing puts unread text on your domain under your name
- Volume without differentiation costs site-level quality signals, not just page-level ones
- The automatic link exchange network is the category search guidelines address as link schemes
