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

Pick Profound if

• Fits if you're a large brand that wants answers tracked on up to 9 engines and can sign a custom contract
• Works for agencies running pitch audits for prospects, at $99 a month for 10 short workspaces

Look elsewhere if

• Skip it if you want to sign up and pay without a sales call, as brands can't
• Pricey if you're an agency with several clients, at $399 a month per client workspace on top of $99
• Tight if you want to test your own questions, since the trial's prompts are fixed
• Watch out: custom prompts, the API, exports and SSO all come only with Enterprise
• Watch out: agents spend credits, and extra credits need an Enterprise package with overage billing or a pause

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

Profound

• Brands have no self-serve paid plan: after the 7-day trial, ongoing tracking needs a custom-priced Enterprise contract.
• Trial users get a recommended prompt set and cannot edit it; custom prompts, API access, exports and SSO come with Enterprise.
• On Agency Growth, each full client workspace is a $399-a-month add-on and 5 more trial workspaces cost $199 a month.
• Agent runs use credits; extra credits beyond the plan need an Enterprise package, with overage billing or a pause set by the account team.

Relixir

• No prices are published; Rex is sold on custom pricing after a demo.
• It is not self-serve: Relixir's team configures, launches and manages Rex for each customer.
• Rex writes and publishes content to your CMS on its own schedule, including refreshes every 30 to 60 days.
• The engines it names are ChatGPT, Perplexity, Claude and Google AI Overviews; Gemini and Copilot are not mentioned.
