Best AI SEO Agents (2026): Mentionova $99 + 6 More, Compared

The best AI SEO agents in 2026 are Mentionova, AirOps, GrowthX, Writesonic, Peec AI, AthenaHQ and Profound. Mentionova is #1 because its agent, Nova, is built for the whole SEO and AI-search job: ask for an outcome in plain language and it reads your AI citations, Search Console data and competitors, then builds the work, from refresh briefs to citation campaigns, for you to approve. Starter is $99 a month billed annually with 100 agentic tasks. Pick Mentionova if you want an agent that tracks AI visibility and acts on it in one place; skip it if you mainly need a high-volume content production engine wired into your CMS, where AirOps or GrowthX fit better.

How did we pick these AI SEO agents?

An AI SEO agent should return work, not just a report. We kept tools whose own pages describe agents that research, draft or act on search and AI-visibility data, then ranked them on four things:

1. Grounding. Does the agent work from your own data, such as citations, Search Console and competitors?
2. Output. Does it produce briefs, drafts or actions you can ship?
3. Control. Can your team approve what goes out?
4. Clear pricing. Is there a published price and a usage allowance?

Every price and feature below comes from the vendor’s own page, fetched October 27, 2026. For broader tool lists, see AI SEO tools and AEO platforms.

What are the best AI SEO agents?

1. Mentionova: best AI SEO agent overall

Why it’s #1: Nova is the AI SEO agent built into Mentionova. You ask for an outcome and Nova reads your citations, Search Console data and competitors, runs the tools the task needs and builds the result: a grid of refresh briefs, a citation campaign or a workflow. Each reply lists the tools Nova ran, so you can see what the work involved.

• Price: Starter is $99/mo billed annually ($125 monthly) with 100 agentic tasks and 25 tracked prompts. Scale is $320/mo billed annually ($400 monthly) with 500 tasks and 100 prompts. Enterprise is $799/mo billed annually ($999 monthly) with 2,500 tasks and 250 prompts.
• Control: Nova does not publish, post or send on its own. Campaign targets stay unassigned until you assign them, and workflows with a review step wait for approval.
• Tracking: Mentionova tracks ChatGPT, Perplexity, Claude, Gemini, Google AI and Reddit, so the agent works from what AI engines actually say about you.
• Trade-off: it is an SEO and AI-visibility agent, not a general-purpose chatbot.

A year of Starter is $1,188. See Mentionova pricing and the Mentionova review.

2. AirOps: best for content operations at scale

AirOps combines agents, data, brand governance and expertise to research, publish and refresh content. Solo includes 35,000 tasks for content production and ChatGPT insights only; Pro includes 100,000 tasks, insights across 7+ answer engines and unlimited seats; Enterprise adds custom agent builds. Solo users pay $0.025 for each extra task.

• Trade-off: plan prices are not listed on the pricing page; you start for free or talk to sales.

3. GrowthX: best for teams that want agents plus experts

GrowthX turns buyer questions into content: you brief, draft, create and optimize with agents you can guide and improve, with built-in grading to keep quality high. GrowthX says it was built by SEO, AEO and content experts who learned from 100+ customers.

• Trade-off: no public pricing; you book a demo.

4. Writesonic: best budget agentic workflows

Starter is $79/mo billed annually with 15 AI articles a month and 10 agentic workflow trial runs; Basic is $199 with 50 trial runs and Growth is $399 with 100. Writesonic’s pitch is to find which prompts recommend competitors and fix it with AI agents.

5. Peec AI: best agent on top of a tracker

Starter is $95/mo with agent credits included. The Peec Agent generates actions from your data using pre-built and custom skills, with company and per-project context so it answers about the right brand.

6. AthenaHQ: best free start

Essential is free with 300 credits and includes the Athena AI agent. Starter is $295/month with 3,600 credits, visibility across 11 models, on-page and off-page actions and a content optimization agent; the advanced agent is on Enterprise.

7. Profound: best for enterprise marketing teams

Profound’s Agents let teams build and reuse workflows for recurring marketing work, and Enterprise adds AI Marketer credits for the whole team and up to 9 answer engines. The free Trial runs 50 prompts daily for 7 days.

How much do AI SEO agents cost per year?

At list price, Writesonic Starter is $948 a year billed annually, Peec AI Starter $1,140 and Mentionova Starter $1,188. AirOps, GrowthX and Profound Enterprise are quoted. Compare what the price buys: Mentionova’s 100 agentic tasks a month sit next to AI-visibility tracking, while Writesonic’s Starter limits agentic workflows to 10 trial runs.
