Win in Google. And in the AI answers.
v0.9 adds the half of 2026 search every marketer is asking about: are the AI assistants citing you, what demand are you missing, and did your last change actually move rankings.
Are the AI assistants citing you?
See whether ChatGPT, Perplexity, Gemini, and Google AI Overviews mention your brand for the prompts that matter. Track your share of voice against competitors over time, find out if AI is already sending you traffic, and get your pages structured so AI quotes you.
Find the searches you're missing.
Most tools only show what you already rank for. SEOmonster surfaces net-new keywords you have no footprint on yet, plus the exact gaps your competitors rank for that you don't.
Prove it actually worked.
Shipped a change? Get an honest before/after that separates your impact from Google's algorithm noise, plus the specific internal links and on-page gaps to fix next.
The SEO data you already pay for, finally working for you.
Your Search Console, GA4, PageSpeed, and Cloudflare hold everything you need to win, locked in dashboards you barely open. SEOmonster unifies them behind one AI assistant that actually acts on the data: free, open source, running on your own machine.
Your data sources, one server
Search Console, GA4, PageSpeed, Cloudflare, IndexNow, Chrome UX, plus a stdlib HTTP client for technical-SEO checks. 70 tools in all, now including AI-answer tracking and keyword discovery built on your own data, with optional external sources for competitor and AI-citation insight.
MCP-native, not a wrapper
Built on the Model Context Protocol. Each tool returns a clean envelope with explicit readOnlyHint, destructiveHint, and openWorldHint annotations.
Your credentials stay yours
OAuth token cached at ~/.config/seo-monster/ with mode 0600. We hold nothing server-side because there is no server-side.
Ten capability surfaces. 70 tools. One uvx seo-monster away.
