All 8 engines on Starter. No demo.
Every Sonarvue paid plan monitors the same eight answer engines - ChatGPT, Claude, Gemini, Perplexity, Google AI Overviews, Microsoft Copilot, Grok, and Kimi - starting at $29/mo. No sales call, no per-engine upsell, no card to start.
The cheapest paid plan is the honest unit of comparison. It is what a buyer actually gets on day one, before any upgrade conversation. This table lists the engines each tool includes on its entry paid tier, from the vendor's own published pages.
| Tool | Cheapest paid plan | Engines included on that plan | Price published? | Demo or sales call? |
|---|---|---|---|---|
| Sonarvue | Starter | All 8, named: ChatGPT, Claude, Gemini, Perplexity, Google AI Overviews, Microsoft Copilot, Grok, Kimi. Same eight on every paid plan. | $29/mo (published) | No demo. Self-serve, no card to start. |
| Profound | Starter | ChatGPT only on Starter; three engines on Growth; up to ten on Enterprise. Other engine names are not published per tier. | Not published (page renders scrambled digits; billed yearly) | Sales-led at the enterprise end; no free tier. |
| Peec AI | Lowest self-serve tier | "Choose 3 models" on the entry tier; more models are a paid add-on. The models themselves are not named. | Not published (dollar amounts do not render) | Trial CTA; sales contact for enterprise. |
| Otterly.ai | From $29/mo | Engines are not published per tier. Their pages name ChatGPT, Gemini, Perplexity, Copilot, AI Overviews, and AI Mode; Claude appears in citations/MCP imagery only. | Starting price only ("pricing starts at $29/month") | 14-day trial; no free tier. |
| Rankscale | Entry paid plan | 17+ named engines on every plan with no per-engine upsell. On raw engine count they beat Sonarvue; the trade is credit-metered usage. | $20/mo entry; credit-metered tiers up to $780 | Self-serve. |
| AthenaHQ | No public self-serve tier | 8+ named engines including Grok, but not mapped to a published tier. | Not published (no pricing page in their public site) | Demo-walled, sales-led. |
| Semrush AI Visibility Toolkit | AI Visibility Toolkit | 1 domain for Brand Performance and 25 Prompt Tracking prompts, with paid add-ons for domains, prompts, and users. Engine coverage is not enumerated per tier. | $99/mo (published in their knowledge base) | Self-serve inside the Semrush suite. |
Facts as published by each vendor and checked September 2026. Where a detail is not public, the table says "not published" - that is not the same as "not offered". Rankscale beats Sonarvue on raw engine count (17+); Sonarvue's claim is all eight engines on the cheapest tier, named, at a published price.
Why the cheapest plan is the honest comparison
AI visibility platforms increasingly tier by engine, not by the job. An entry plan that tracks one engine still produces a dashboard, a score, and a confident summer headline - but it does not answer the question a buyer is asking: does the AI recommend us, on the engine our buyers actually use? If the plan only reads ChatGPT, then Gemini, Perplexity, and the rest are invisible by construction.
Three packaging moves distort the comparison: gating engines per tier, hiding the price behind a demo, and metering usage with credits that can run out. The entry-tier engine list cuts through all three - it is the coverage you hold before any upgrade.
What this table does not claim
- Sonarvue does not have the largest engine count. Rankscale publishes 17+ on every plan; we say so above.
- A higher tier from another vendor may include more than its entry plan. The table is about the cheapest paid tier, not the ceiling.
- We do not treat an unpublished price as free, and we do not call a hidden tier a feature.
- Sonarvue is a vendor in this category. We make it, so read this table the way you would read any vendor comparison.
How we check
Each row comes from the vendor's own public pricing, product, or knowledge-base page, checked in September 2026. Engine counts are separated from monitoring depth, cadence, and answer evidence - a longer engine list is not automatically a better answer. Vendors change packaging without notice, so confirm on their page before you buy.

How many answer engines does Sonarvue include on the cheapest paid plan?
All eight: ChatGPT, Claude, Gemini, Perplexity, Google AI Overviews, Microsoft Copilot, Grok, and Kimi. Starter is $29/mo and includes the same eight engines as Growth and Scale, with no per-engine or model add-on.
Do I need a demo or sales call to see Sonarvue?
No. Sonarvue is self-serve with a seven-day trial, 10 tracked prompts, and no card required. There is no demo gate and no sales-led onboarding.
Does Profound include every engine on its cheapest plan?
As published in September 2026, no. Profound's Starter tier is ChatGPT tracking only, Growth covers three answer engines, and Enterprise goes up to ten. Profound does not publish its price on the page.
Does any tool in this table include more engines than Sonarvue?
Rankscale does. Rankscale publishes 17+ named engines on every plan and no per-engine upsell. Sonarvue's position is not the biggest engine count; it is all eight engines on the cheapest tier, named, with a published price and no demo.
How was this table built?
From each vendor's own public pricing, product, or knowledge-base pages, checked in September 2026. Where a vendor does not publish a detail, the table says "not published" rather than guessing. Vendors change packaging, so re-check before buying.
