At Brand Mender, we have put together a quick list of the best AI SEO content writing tools to pick from in 2026:

1. Ahrefs

Ahrefs isn’t primarily a writing tool, but its Content Explorer is one of the most powerful instruments for planning content with a realistic chance of ranking. You can search for any topic and filter by traffic, backlinks, domain rating, and publishing date to find what’s working right now in your niche.

Its 2026 updates include AI-filtered content discovery that deprioritises low-quality AI-generated pages and a “Link Intent” scoring system that predicts how much traffic a new page will realistically drive.

Best for – SEO professionals, link builders, and competitive researchers who want the deepest data for content planning.

Semrush remains one of the most comprehensive AI SEO platforms available. Its Content Toolkit combines keyword research, competitor analysis, search intent insights, and AI-assisted content generation into a single workflow.

What makes Semrush one of the best AI SEO content writing tools is its ability to create content based on real search data rather than generic AI prompts. Users can generate article outlines, identify ranking opportunities, and optimise drafts using live SERP insights.

Best for:

• Structured

A standout feature is the ability to upload brand guidelines, tone-of-voice documents, and past examples so outputs match the existing style.
