Stellarcast vs Profound: which AI visibility platform fits you?

Both track whether AI engines name your brand, and both can now push fixes to your site. The real differences are how you buy them, which engines your plan includes, and how each one proves a change worked. Here's an honest, side-by-side look.

We'll be straight about our bias: Stellarcast is our product. This comparison is meant to be useful anyway, so it says plainly where Profound is the better choice. Every fact about Profound below comes from Profound's own pricing and product pages, checked on 26 September 2026. Plans in this category change often, so confirm anything that decides your purchase with the vendor.

The short answer

Profound is an enterprise AI-marketing platform: the widest engine list, 30+ languages, server-log crawler analytics, SOC 2, and AI agents that draft content and publish it to your CMS after an approval. Brand plans are sold through sales, not a price list.

Stellarcast is built for teams that want the whole loop, monitor, diagnose, fix and prove, on a plan they can buy today. Every paid plan checks six AI engines daily, pricing is public from $39 a month, and every lift claim carries a confidence label, so you can tell a measured result from an early signal.

Side by side

Checked 26 September 2026 against each vendor's own pages.

Stellarcast publishes its full ladder rather than quoting per deal: see the plans and what each one tracks, or run a free audit and see your own numbers before you choose one.

Where Profound wins

If you need the broadest possible engine list, dozens of languages and regions, crawler behaviour straight from your server logs, and enterprise procurement boxes ticked (SOC 2 Type II, SSO, RBAC), Profound is hard to beat. Its agents also go beyond monitoring: they draft content and publish it to a long list of CMSs, with a human approval step. A third of the Fortune 100 is a real signal of staying power.

Where Stellarcast wins

• You can buy it today, at a price you can see. Lite is $39 a month, Growth (which adds proof of lift) is $249, and agency plans start at $599. No demo is required to find out what it costs.
• Six engines on every plan. The entry plan checks the same six engines daily as the top one, including both of Google's AI surfaces. On Profound, trial and agency workspaces track three.
• Proof you can defend. Stellarcast's lift ledger ties each shipped change to a before-and-after movement and labels it MEASURED, LIKELY or TOO-EARLY, with ranges rather than single numbers. A "+23%" never appears without the label that says how sure we are.
• Every market measured on its own. A German brand is measured with the questions a German buyer types, not an English prompt set, and results are never blended into one global average.

How to decide

• Choose Profound if you are an enterprise that wants the widest engine and language coverage, log-level crawler analytics and an agentic content platform, and you are comfortable with a sales-led contract.
• Choose Stellarcast if you want monitoring, fixes and provable lift in one loop, on a plan with a public price, without waiting for a quote.

Questions to ask in either trial

• Show me a real gap for my domain. Not a sample account: a prompt where I'm invisible and a competitor is cited. Does the tool explain why?
• Which engines does my plan actually include? Engine lists on marketing pages often describe the top tier. Ask what the plan you are buying checks, and how often.
• How do I prove a fix worked? If I change a page today, can the tool tie a later lift to that change, and will it tell me when the evidence is too thin to say?
• What's the total cost to a proven outcome? Add the subscription, seats, credits and the internal hours needed to ship a change. Compare on that, not the sticker.
