Most competitors charge extra for each engine. Here's why monitoring all of them matters.
Each AI engine has different training data, citation preferences, and recommendation logic. ChatGPT, Perplexity, Gemini, Claude, and DeepSeek serve hundreds of millions of users combined — and they don't agree on who to recommend.
Peec charges EUR 20-30/mo per additional engine. Otterly charges $9-149 for Gemini add-on. A "cheap" $95/mo plan becomes $180-225/mo once you add the engines you actually need. avisibli includes all 5 on every plan — no surprises.
What works on Perplexity (citations, academic sources) differs from ChatGPT (authority signals) and Gemini (freshness, structured data). You need data from all engines to know what to optimize for each one.
Most GEO tools stop at monitoring. avisibli tells you what to do about it.
Shows the dollar impact of your AI invisibility. Not vanity metrics — actual estimated revenue you're losing because AI engines don't recommend you.
An AI assistant trained on YOUR workspace data. Ask it why you're not getting mentioned, what content to create, or how to outrank a specific competitor in AI responses.
Test different prompt phrasings across all 5 engines. See which version gets your brand mentioned more — then optimize your content accordingly.
Queries all 5 engines for what they want to cite on a topic, then synthesizes it into a GEO-optimized content brief and full article draft with schema markup.
20+ technical checks for AI readiness: llms.txt, schema.org, structured data, static content ratio, AI crawler access, and more. Auto-generates fix code.
See exactly which sources AI engines cite when answering questions in your space. Find citation gaps where competitors are referenced but you're not.
Most competitors gate engines behind add-ons. Here's what it actually costs to monitor all major AI engines.

The best GEO tool depends on your needs. avisibli offers the best value for multi-engine monitoring with 5 engines on every plan starting at $99/mo. Otterly AI is the cheapest entry at $29/mo but with 4 engines. Ahrefs Brand Radar has the largest prompt database (200M+) but costs $948+/mo. For content generation alongside monitoring, Gauge and Writesonic include article generation.
avisibli tracks 5 AI engines on every plan, including the free tier: ChatGPT (OpenAI), Perplexity, Gemini (Google), Claude (Anthropic), and DeepSeek. No add-ons or upgrades required.
Otterly AI starts cheaper at $29/mo for 15 prompts with 4 engines (ChatGPT, AIO, Perplexity, Copilot). avisibli's Starter at $99/mo includes 25 prompts with 5 engines (adding Gemini, Claude, and DeepSeek natively). Otterly charges extra for Gemini ($9-149/tier). avisibli also includes revenue tracking, strategy AI chat, content generation, and GEO audit.
Profound's $99 Starter only monitors ChatGPT — a single engine. Multi-engine monitoring starts at $399/mo (3 engines). avisibli offers 5 engines at $99/mo. Profound raised $96M at a $1B valuation, but avisibli provides more engines and unique features like revenue loss estimation and AI strategy chat at half the price.
avisibli offers the best value. At $99/mo, you get 5 engines included. Comparable multi-engine coverage costs $238+ at Otterly, ~$180-225 at Peec, $399 at Profound (still only 3 engines), $599 at Gauge, and $948+ at Ahrefs.
avisibli is the only GEO platform with built-in revenue loss estimation and revenue forecasting. It calculates the dollar impact of AI invisibility and tracks AI-sourced visits through to leads and revenue. Gauge integrates with GA4/GSC but doesn't calculate revenue impact directly.
PromptScout offers a free tier with 5 prompts and 2 engines. avisibli's free plan scans 3 prompts across all 5 engines. Otterly's Lite starts at $29/mo for 15 prompts with 4 engines. However, cheap tools have limitations — PromptScout lacks competitor tracking, and Otterly's $29 tier is limited to 15 prompts.
For massive-scale monitoring, Ahrefs Brand Radar offers a 200M+ prompt database across 6 engines ($948+/mo). For mid-market enterprise, avisibli's Enterprise ($499/mo) provides 3 workspaces, 5 team members, 300 prompts, board reports, and outreach tools. Profound targets large enterprise with custom pricing at $2-5K+/mo.
Three platforms include content generation: avisibli generates content briefs by querying all 5 engines, then creates GEO-optimized article drafts. Gauge includes 3-18 articles/mo. Writesonic bundles GEO with a full AI content platform. Otterly, Peec, Profound, and PromptScout focus solely on monitoring.
Most tools gate engines behind tiers or add-ons. True multi-engine costs: avisibli $99/mo (5 engines included), Peec ~$180-225/mo (3 base + 3 add-ons), Otterly $238+/mo (Standard + Gemini), Profound $399/mo (3 engines), Gauge $599/mo (7 engines), Ahrefs $948+/mo (6 engines). Only avisibli includes all engines on every tier.
