Airefs vs Relixir (2026): which should you pick?

Pick Airefs if

• Fits if ChatGPT is the AI engine your buyers actually use
• Works for small teams who want articles and outreach drafts in the same tool as tracking

Look elsewhere if

• Skip it if you need Gemini, Claude or Perplexity tracked, as it covers ChatGPT only
• Tight if you're on Lite, with checks every other day, 1 country and 7 days of history
• Pricey if you want AI Overviews, a $10 to $30 monthly add-on, or extra articles at $7 each
• Watch out: there's no free plan, only a 7-day trial, and the listing doesn't say if it needs a card
• Not for you if you need an API: none is listed, only a read-only MCP server from Pro

Pick Relixir if

• Fits if you'd otherwise hire an agency to write, publish and refresh content for AI answers
• Works for B2B companies that want AI traffic and AI-sourced leads in the report

Look elsewhere if

• Not for you if you want a price before a sales call, as Rex is sold on custom pricing after a demo
• Skip it if you want to sign off every page, as Rex publishes to your CMS on its own schedule
• Too light for teams that need Gemini or Copilot answers watched, as neither is named
• Skip it if you want to try it first, as there's no free plan or trial
• Watch out: it isn't self-serve, so Relixir's team configures, launches and manages it for you
