profound pricing
Profound publishes two self-serve plans. Starter is $99 a month, or $82.50 billed annually, and covers ChatGPT alone: 50 tracked prompts and 1,500 responses a month. Growth is $399 a month, or $332.50 billed annually, and adds Perplexity and Google AI Overviews: 100 prompts, 9,000 responses a month, and three seats. Enterprise is custom and reaches up to nine engines.
Both plans refresh daily, which is where those monthly totals come from. Fifty prompts against one engine, every day, is 1,500 responses a month. The table above states the same figures per refresh instead, so the two platforms can be read against one measurement rather than one calendar month.
Centium is $99 a month billed annually for 120 prompts across six models, 720 responses per refresh, unlimited seats, and export. See eight leading AI visibility platforms ranked or Centium’s own pricing.
depth or frequency
Profound asks 50 questions of one model every day. Centium asks 120 questions of six models on a considered cadence. Neither is wrong, but they answer different problems.
Daily tracking of a single engine is an SEO-shaped habit: watch the number, react to the movement, watch again tomorrow. It suits teams optimizing content day over day, and Profound is good at it.
Centium is built for the long game of digital presence. AI models are non-deterministic, so a wider sample is a more accurate one, and a reading across six models tells you where you actually stand rather than how one engine felt today. The gap between measurements is deliberate: it is the room to run the PR, fix the pages, and earn the citations before anything is measured again.
Every Centium plan includes the full platform, including query fan-out, which shows the sub-questions a model asks itself before it answers. The only thing that changes between plans is how often the data refreshes, from Monthly at $99 to Weekly at $199.
- You want measurement depth. Centium queries six models with 120 prompts each, and reports on a larger dataset from 720 AI responses.
- Your buyers use Claude, Gemini, Perplexity, Google AI Mode, or Grok, not just ChatGPT.
- You are building long-term presence and you want time between measurements to act on what you learned.
- More than one person needs the dashboard, without buying seats.
- You need every feature on the plan you can afford, including export, rather than the ones your tier unlocks.
- You want to watch ChatGPT day by day and react quickly to movement.
- Your business and offerings are simple, and do not require a high volume of prompts to cover different products or segments.
- You need workflow automation to push changes straight into a CMS.
- You want relevant keyword data alongside your prompts, and can reach the Growth plan.
- One seat is enough, and one engine is the engine you care about.
centium or profound.
Centium measures depth: 120 prompts across six AI models in one complete reading. Profound measures frequency: 50 prompts against ChatGPT, refreshed daily. Centium is built for brands setting strategy over quarters. Profound is built for teams watching day-to-day movement in one engine.
Centium tracks six on every plan: ChatGPT, Claude, Gemini, Google AI Mode, Perplexity, and Grok. Profound’s Starter plan tracks ChatGPT only, and its Growth plan tracks three: ChatGPT, Perplexity, and Google AI Overviews.
Profound Starter is cheaper. Billed annually it works out to $82.50 per month, or $990 a year, against Centium at $99 per month, or $1,188 a year. Month to month, Profound is $99 and Centium is $119. What the money buys differs: Centium includes six AI models, 120 prompts, unlimited seats, and export. Profound Starter includes one engine, 50 prompts, one seat, and no export. Profound’s Growth plan, which adds two engines and export, is $332.50 per month.
Profound refreshes daily on every plan. Centium refreshes on a Weekly, Bi-Weekly, or Monthly plan, at $199, $149, and $99 per month billed annually. The cadence is deliberate: a wider measurement gives you more to act on, and leaves time to act before the next one.
Not on the Starter plan. CSV and JSON export begins on Profound’s Growth plan at $332.50 per month billed annually. Centium includes CSV and XLSX export on every plan, along with archived prior reports.
They answer different questions. Profound is the better fit for daily tracking of a single engine, workflow automation, and relevant keyword data on its Growth plan. Centium is the better fit for measurement depth, multi-model coverage, and teams that need more than one seat.
Centium is the best low-cost alternative that delivers premium-plan features and measurement depth. Centium offers six models, 120 prompts, and all platform features in every plan. If you don’t need daily monitoring, Centium provides richer insights than Profound.
