Slash commands: /seo audit, /seo page, /seo schema, /seo sitemap generate, /seo geo. Integrates with MCP servers for live data (Ahrefs, Semrush, GSC, DataForSEO). Works without them too — just analyzes what it can see.
The GEO module is the standout. Optimizes content for AI search engines (Perplexity, ChatGPT, Claude) — citation-friendly formatting, entity markup, structured answers. Most SEO tools don't touch this yet.
Skills give Claude SEO knowledge. MCP servers give Claude live SEO data. These connect Claude Code to your actual analytics and keyword tools.

A full writing workspace with slash commands and platform-specific agents. The workflow: capture ideas in /rawnotes, extract themes with /extract-themes, research with /research, write with /write, then repurpose with specialized agents for LinkedIn, newsletters, X threads, and podcast Q&A scripts.

You seed it with 3-5 examples of your best writing. Claude learns your voice, then applies it across every output.
Removes signs of AI-generated writing. Based on Wikipedia's "Signs of AI writing" guide (maintained by WikiProject AI Cleanup). Detects 24+ patterns: inflated symbolism, promotional language, vague attributions, em dash overuse, rule of three, AI vocabulary ("delve", "pivotal", "landscape"), negative parallelisms. Two-pass approach — diagnose, then rewrite.

Fair warning: it makes text less obviously AI-generated, but doesn't make it sound like you. It strips patterns, it doesn't add voice. Good for a first pass. For voice matching, you need to seed it with your own writing samples.
Researches any topic across Reddit and X from the last 30 days, then writes copy-paste-ready prompts based on what it finds. Pulls from actual threads and posts — not just headlines. Requires OpenAI API key (for Reddit data access) and xAI API key (for X timeline search).

Example: /last30days what are the best cold email frameworks right now — scans Reddit + X, finds what's actually working (with upvote/like counts as signal), then generates a prompt template you can use immediately.
Good for: finding what's trending before you write about it, discovering current frameworks and terminology, generating prompts grounded in real community sentiment.
