The editorial agent, live inside your editor
Surfer SEO gives you a score and a keyword list. Frase gives you a content brief. Both tell you what's wrong. Neither one fixes it. Byline's editorial agent reads your full article, takes the sections the scorer flagged, and rewrites them directly inside your editor, with one click.
The findings come from deterministic code that reads your page, with the evidence shown under each one. The agent, which runs on Claude Sonnet, writes the fix. It never sets a score. Byline does not measure AI visibility, and nothing that reads a page's HTML can.
And because Byline's keyword database is shared across accounts, your research loads from cache on repeat queries. Your results get faster over time, and your cost-per-article stays flat as the platform grows.
One workflow. Research, generate, score and fix, all without leaving Byline.
Tell the discovery agent your topic and audience. It asks the right questions and generates 15–20 targeted keyword seeds before touching the API, so your results fit your topic.
Choose your target word count. Byline generates a fully structured, SEO-optimized article matched to the keyword's search intent, then scores how retrievable and citable it is before you publish.
Select any section. Tell the agent to rewrite it. The fix drops in directly, with no copy-paste and no leaving the editor. The agent also surfaces content gaps and suggests your next article.
Every other tool tells you your H2 is wrong. Byline's agent rewrites it.
Open an article, ask the agent to review it. It reads the full content, identifies specific sentences and sections, and tells you exactly what to change and why.
Select any paragraph. Give an instruction. The agent rewrites it in-place and applies it to your editor with one click. No copy-paste.
Failed a check? One click sends the agent straight to the fix: “Add a FAQ section targeting common questions about [keyword].”
The agent remembers what it told you before, across sessions and articles, so it never repeats itself.
