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

Pick Goodie if

• Fits if you want the tracking and the content work that follows it in one tool, at $295 a month or more
• Works for teams selling products who need SKU-level AI shopping data, which starts on Pro at $999

Look elsewhere if

• Pricey if you just want to know whether ChatGPT mentions you, at $295 a month even on yearly billing
• Tight if you run several brands, as Core covers one brand, two countries and 5 of its 13 engines
• Skip it if you need the API or multi-brand reporting, which only come with Enterprise
• Watch out: Pro jumps to $999 a month, is started through a demo, and is where Slack support begins
• Watch out: agents run on 50 optimization actions a month on Core, and monthly billing adds $59 to Core's price

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
