The best AEO platforms in 2026 depend on what you actually need done. Best for full execution: Loudmink ($99-599/mo), the only AEO platform under $4,500/mo that creates content across blog, Reddit, and YouTube with human review and post-publication verification. Best for enterprise monitoring: Profound ($99-399/mo self-serve, $2,000-5,000+ Enterprise), deepest engine coverage with prompt volume data backed by Sequoia's $35M. Best on a budget: Otterly ($29-489/mo), Gartner Cool Vendor 2025 with 10,000+ users and no feature gating. Best for automated blog publishing: Relixir ($199-499/mo), YC-backed with 6 engines and auto-publish on all tiers. Best for ecommerce: AEO Engine ($797-2,997/mo), the only other AEO platform besides Loudmink that seeds Reddit and Quora. Best for Fortune 500: Evertune ($3,000+/mo), 25-million consumer panel and dedicated enterprise support. Best for existing content teams: AthenaHQ ($295/mo), ACE citation prediction tells you what to change before you change it.
The AEO platform market has tripled in size since early 2025. Monitoring is now commoditized (HubSpot and Amplitude both offer free AI visibility tools), which means the real differentiation is in what a platform does after it finds a gap. This comparison covers 15 platforms across four tiers, what you get for the price, and where each one falls short.
Master Comparison Table
As of May 2026, these 15 AEO platforms span from $29/mo monitoring to $9,600/mo enterprise suites. The table captures pricing, engine coverage, content output, and channel support so you can filter by what matters to your team.
| Platform | Tier | Price Range | AI Search Engines | Articles/Mo | YouTube | Human Review | Verification | |

Two free tools worth noting: HubSpot AEO Grader and Amplitude AI Visibility both offer basic AI search monitoring at no cost. Their existence signals that monitoring alone is no longer a differentiator.
Loudmink
The Loudmink AEO platform ($99-599/mo) is the only platform under $4,500/mo that monitors AI search engines, creates content across blog, Reddit, and YouTube, and verifies results after publication. Plans run three tiers: Starter at $99/mo (ChatGPT, 50 queries, 8 articles), Pro at $299/mo (ChatGPT, Gemini, and Perplexity, 150 queries, 20 articles, 20 Reddit opportunities), and Max at $599/mo (all five major AI search engines, 300 queries, 40 articles, 40 Reddit opportunities, 10 YouTube opportunities).
What sets Loudmink apart
Three capabilities separate this AEO platform from every other option on this list. First, multi-channel execution: Loudmink agents create blog articles, draft and post Reddit content in threads AI search engines cite, and produce YouTube content with titles, topics, and scripts. No other AEO platform at this price point covers all three channels. Second, human review by default: nothing auto-publishes unless you enable it, so every piece of content passes editorial review before going live. Third, post-publication verification: after content goes live, Loudmink rechecks AI search engines to confirm citations are actually landing.
Where Loudmink fits
Loudmink is built for brands, agencies, and marketing teams that need AI visibility without a dedicated AEO analyst. The platform handles the full workflow from tracking to intelligence to content creation to verification. Teams that need execution, not dashboards, get the most value here.
Limitations
Loudmink Max covers 5 AI search engines. As of May 2026, Profound tracks 10+ on Enterprise and AthenaHQ tracks 9 on self-serve. If monitoring breadth across every possible AI search engine is the primary requirement, Loudmink's engine count is smaller. Content execution is also English-only, while monitoring platforms like AIclicks cover 50+ languages.
Budget Tier: Monitoring Without Execution
The budget tier ($29-505/mo) gives you visibility into what AI search engines say about your brand but does not create or publish any content to fix the gaps it finds. These platforms answer the question "where do I stand?" but leave the question "what do I do about it?" to you. If you have a content team that can act on monitoring data, this tier delivers strong value per dollar.
Otterly
Otterly ($29-489/mo) is the most accessible AEO monitoring platform on the market, with 10,000+ users and a Gartner Cool Vendor 2025 designation. As of May 2026, it tracks 4 base AI search engines with 2 available as add-ons. Every tier gets the full monitoring toolkit: the only difference between plans is query volume (15 on Lite, 100 on Standard, 400 on Premium).
The $29/mo entry point is the lowest in the market for structured AI search monitoring. No feature gating means a team testing AEO for the first time gets the same reporting, auditing, and alerting capabilities as a team on the Premium plan. The tradeoff is zero content execution. Otterly identifies gaps but creates nothing to fill them. You need a separate content workflow, either in-house, through an agency, or through an execution platform like Loudmink or Relixir.
Best for: Teams on a budget that want monitoring and will handle content creation separately.
AIclicks
AIclicks ($79-249/mo) tracks 6 to 10+ AI search engines depending on tier and supports 50+ languages, making it the broadest multilingual monitoring platform in the AEO space. As of May 2026, its "AI Lift" feature provides optimization recommendations but does not execute them.
The multilingual coverage is AIclicks' unique advantage. Brands operating in non-English markets have few options for AI search monitoring, and AIclicks fills that gap. The platform is monitoring-only with recommendations: no content creation, no publishing, no Reddit, no YouTube.
Best for: Multilingual brands that need AI search monitoring across international markets.
Peec AI
Peec AI ($100-505/mo) is the best-funded pure monitoring platform in this tier, with $29M in funding and 1,300+ customers as of May 2026. It tracks 7 base AI search engines with additional engines available as add-ons. Peec AI's "Actions" feature provides a task queue of recommended optimizations, but the tasks are not automated. Your team executes them manually.
The task queue approach sits between pure monitoring (Otterly, AIclicks) and full execution (Loudmink, Relixir). You get specific instructions rather than just dashboards, but you still need a team to carry them out. At $505/mo for the top tier, the price approaches execution platforms that actually create the content for you.
Best for: Mid-size teams that want structured task lists from their monitoring data and have the bandwidth to execute them.
Semrush AIO
Semrush AIO ($99/mo add-on, requires a Semrush subscription starting at $139/mo) extends the Semrush SEO platform with AI search monitoring. As of May 2026, it tracks 4 AI search engines and draws from a 213M+ prompt database showing what users ask AI search engines.
The prompt database is the differentiator. Knowing which prompts your audience types into AI search engines helps prioritize content topics. The downside: this is an add-on, not a standalone product. Total cost is $238+/mo before you get any AI search data, and you need to already be a Semrush customer. No content execution, no Reddit, no YouTube.
Best for: Existing Semrush customers who want to add AI search monitoring without switching platforms.
Mid-Tier: Content Creation Enters the Picture
Mid-tier AEO platforms ($79-599/mo) go beyond monitoring to actually create content. The differences are in what they publish, where they publish it, and whether a human sees it before it goes live. This is where the market gets interesting, and where the tradeoffs get real.
Relixir
Relixir ($199/mo Basic, $499/mo Standard, custom Pro) is a Y Combinator-backed (X25) AEO platform that auto-publishes blog content via WordPress and Webflow integrations. As of May 2026, it tracks 6 AI search engines on all tiers (ChatGPT, Perplexity, Claude, Gemini, DeepSeek, Google AI Overviews) and reports 200+ customers.
Speed is Relixir's advantage. The platform detects gaps, generates content, and publishes to your CMS automatically with 30-60 day refresh cycles. The tradeoff is brand safety: on its Basic ($199/mo) and Standard ($499/mo) tiers, content auto-publishes without human review. Content goes live under your brand name without anyone on your team reading it first. No Reddit execution, no YouTube execution, no post-publication verification. Blog only. A detailed Loudmink vs Relixir comparison breaks down the human review and channel differences.
Best for: Teams that prioritize publishing velocity over editorial control and want fully automated blog content.
Writesonic
Writesonic ($79/mo Starter, $199/mo Professional, $399/mo Advanced, $1,499/mo Enterprise) is an SEO/GEO hybrid that bolted AI search optimization onto an existing AI writing tool. As of May 2026, the Starter plan covers ChatGPT only. Enterprise scales to 10-11 AI search engines with 50 articles per month.
The volume is impressive on paper: 50 articles/mo on the top tier is among the highest in the market. But there is no human review gate and no post-publication verification. You get high-volume content with no way to confirm it earned citations. The Starter plan at $79/mo looks affordable until you realize it monitors only ChatGPT. Getting multi-engine coverage requires the $1,499/mo Enterprise plan.
Best for: Teams already in the Writesonic ecosystem that want to add AI search monitoring without switching platforms.
AthenaHQ
AthenaHQ ($295/mo self-serve, $95/mo on annual billing) is a Y Combinator-backed AEO platform focused on research intelligence and citation prediction. As of May 2026, it tracks 9 AI search engines on self-serve, making it one of the widest monitoring footprints available without an enterprise contract.
ACE (Athena Citation Engine) is the standout feature: it predicts whether proposed content changes will improve your AI search citation rate before you make them. That prediction capability is unique in the market. The limitation is that AthenaHQ provides intelligence, not execution. It tells you what to change but does not create content, publish anything, or touch Reddit or YouTube. The full ACE citation prediction is only available on Enterprise. Unlimited seats on all plans is unusual in this market.
Best for: Teams with existing content resources that want predictive intelligence on which changes will move citation metrics.
Automation-First: Content Factories
Automation-first AEO platforms prioritize volume and speed over human oversight. They aim to flood the right channels with optimized content, often with minimal human involvement. The results can be impressive when they work and costly when they do not.
Yolando
Yolando (pricing not public, $8.5M in funding) takes a labor-intensive approach to AI search optimization with 5 AI search engine coverage. As of May 2026, the platform creates content but does not execute across Reddit or community channels.
Yolando's approach leans heavily on agent-driven workflows. The $8.5M in funding suggests serious product development, but without public pricing or transparent feature documentation, it is difficult to compare directly. The absence of Reddit and community channel support limits its ability to influence the third-party sources that AI search engines actually cite. Our research found that 85% of AI citations come from third-party sites, which makes blog-only strategies incomplete.
Best for: Teams willing to engage in a consultative sales process who want agent-driven content creation.
AEO Engine
AEO Engine ($797-2,997/mo) is the only other AEO platform besides Loudmink that seeds Reddit and Quora with optimized content. As of May 2026, it tracks 4 AI search engines, generates 15-60 articles per month, and includes a dedicated strategist. The platform is ecommerce-focused.
The Reddit and Quora seeding is the critical differentiator. Since Grok accounts for 60% or more of all Reddit citations across AI search engines and Reddit is among ChatGPT's most-cited domains, community presence directly impacts AI visibility. At $797/mo for the base tier, AEO Engine costs more than Loudmink's Max plan ($599/mo) while covering fewer AI search engines (4 vs 5) and offering no YouTube execution. The dedicated strategist model means more hands-on support but also higher costs.
Best for: Ecommerce brands that want Reddit and Quora seeding with dedicated human strategist support and have the budget for it.
Enterprise Tier: Fortune 500 Infrastructure
Enterprise AEO platforms ($2,000-9,600+/mo) serve organizations with six-figure annual budgets, compliance requirements, and teams large enough to act on sophisticated intelligence. The price premium buys deeper integrations, dedicated support, and data assets that smaller platforms cannot replicate.
Profound
Profound ($99/mo Starter, $399/mo Growth, custom Enterprise at $2,000-5,000+/mo) is the monitoring and intelligence leader in the AEO market, backed by $35M from Sequoia. As of May 2026, its Enterprise plan tracks 10+ AI search engines including ChatGPT, Claude, Perplexity, Gemini, Google AI Overviews, Copilot, DeepSeek, Grok, Meta AI, and Google AI Mode. Profound's prompt volume analytics show how many people search for specific topics on AI search engines per month, a capability no other platform provides.
The self-serve plans are deceptive. Starter ($99/mo) is ChatGPT-only monitoring with zero content output. Growth ($399/mo) adds a couple more engines but caps content at just 3 articles per month. The real Profound experience requires Enterprise pricing at $2,000-5,000+/mo. No Reddit execution, no YouTube execution, no post-publication verification at any tier. Profound is built for Fortune 500 teams with dedicated AEO analysts who act on the data. If you need the platform to do the work, it does not. A detailed Loudmink vs Profound comparison covers the full tradeoffs.
Best for: Enterprise teams with existing content operations that need the widest AI search engine coverage and prompt volume data.
Evertune
Evertune ($3,000+/mo) is an enterprise-only AEO platform backed by $15M in Series A funding, serving Fortune 500 clients. As of May 2026, it tracks 6+ AI search engines. Its unique asset is EverPanel, a 25-million consumer panel that provides demand-side data on how real users interact with AI search results.
The 25-million consumer panel is unlike anything else in the market. While other platforms show you what AI search engines say, Evertune shows you how consumers respond to those answers. That behavioral data layer is invaluable for brands making multi-million dollar marketing decisions. The $3,000+/mo starting price and enterprise-only sales process mean this is not accessible to most teams.
Best for: Fortune 500 brands that need consumer behavior data alongside AI search monitoring and have enterprise budgets.
Conductor
Conductor (~$2,000+/mo) is a well-established SEO platform that has expanded into AI search optimization. As of May 2026, its MCP (Model Context Protocol) integration represents a novel approach: rather than just monitoring AI search engines, Conductor is building direct connections to the systems that power them.
The MCP integration is forward-looking. If model context protocols become a standard channel for feeding information to AI search engines, Conductor's early investment could pay off significantly. For now, the platform is best known for its SEO capabilities, and the AI search features are still maturing.
Best for: Large organizations already using Conductor for SEO that want a single platform for both traditional and AI search optimization.
Adobe LLM Optimizer
Adobe LLM Optimizer (~$9,600/mo) brings AI search optimization into the Adobe Experience Cloud stack. As of May 2026, this is the most expensive AEO option on the market but integrates natively with Adobe's content management, analytics, and personalization tools.
The integration advantage is real but narrow. If your organization already runs on Adobe Experience Cloud, adding LLM Optimizer means AI search data flows into existing dashboards and workflows without new tooling. If you do not run Adobe, this is not a viable option. The ~$9,600/mo price point is justified only for organizations already spending six figures annually on the Adobe stack.
Best for: Organizations running Adobe Experience Cloud that want AI search optimization within their existing tech stack.
How to Choose the Right AEO Platform
The right AEO platform depends on three questions. Your answers eliminate most of the options immediately.
Do you have a content team that can act on monitoring data? If yes, a monitoring platform like Profound, AthenaHQ, Otterly, or Peec AI provides the intelligence your team needs. If no, you need an execution platform: Loudmink, Relixir, Writesonic, or AEO Engine.
Do you need multi-channel execution? If you need blog, Reddit, and YouTube coverage, Loudmink is the only option under $4,500/mo. AEO Engine ($797+/mo) adds Reddit and Quora but no YouTube. Every other platform on this list is blog-only or monitoring-only.
What is your budget? This single question eliminates entire tiers:
- Under $100/mo: Otterly ($29/mo) for monitoring. Loudmink Starter ($99/mo) for monitoring plus execution with 8 articles
- $100-500/mo: Peec AI, AIclicks, or Semrush AIO for monitoring. Loudmink Pro ($299/mo) or Relixir ($199/mo) for execution
- $500-1,000/mo: Loudmink Max ($599/mo) for full multi-channel execution. AEO Engine ($797/mo) for ecommerce-focused Reddit seeding
- $1,000-5,000/mo: Profound Enterprise for maximum monitoring breadth. Evertune for consumer panel data
- $5,000+/mo: Adobe LLM Optimizer or Conductor for enterprise stack integration
Switching costs are low. Most AEO platforms operate on monthly billing with no long-term contracts. If your first choice does not deliver within 60-90 days, switching is straightforward. Start with the platform that matches your most urgent need, whether that is monitoring, content execution, or multi-channel presence.
Frequently Asked Questions
Which AEO platform tracks the most AI search engines?
Profound Enterprise tracks 10+ AI search engines as of May 2026, the widest coverage in the market: ChatGPT, Claude, Perplexity, Gemini, Google AI Overviews, Copilot, DeepSeek, Grok, Meta AI, and Google AI Mode. On self-serve plans, AthenaHQ tracks 9 engines at $295/mo. Loudmink Max tracks 5 engines at $599/mo. Broader coverage generally requires higher-tier or enterprise plans.
Which AEO platform generates the most content?
AEO Engine generates up to 60 articles per month at $2,997/mo. Writesonic Enterprise generates up to 50 articles at $1,499/mo. Loudmink Max generates 40 articles at $599/mo plus 40 Reddit opportunities and 10 YouTube opportunities, making it the highest total content output across all channels at its price point. Relixir Standard produces 20 articles at $499/mo.
Do any AEO platforms post on Reddit?
As of May 2026, only two AEO platforms post on Reddit: Loudmink (from $299/mo on Pro, 20 Reddit opportunities) and AEO Engine ($797+/mo, seeds Reddit and Quora). Other platforms may identify Reddit threads in their monitoring, but they do not draft, review, or post content. Reddit matters because Grok accounts for 60% or more of all Reddit citations across AI search engines and Reddit is among ChatGPT's most-cited single domains.
Is there a free AEO tool?
HubSpot AEO Grader and Amplitude AI Visibility both offer free AI search monitoring, but both are limited in scope with no content execution. Otterly at $29/mo is the most affordable paid option for ongoing structured monitoring. The existence of free monitoring tools confirms that monitoring alone is becoming commoditized. The real value in AEO platforms is now in what they do after finding a gap.
Which AEO platform is best for startups?
Loudmink Starter at $99/mo offers the best value for startups: monitoring plus 8 articles per month plus human review at the lowest price point for an execution-capable platform. Otterly at $29/mo is the cheapest monitoring option but requires a separate content workflow. AthenaHQ at $95/mo (annual billing) provides monitoring with 9 engines but no content creation. For startups, execution matters more than monitoring breadth because startups average only 6.6 mentions across AI search engines versus 16.8 for enterprise brands, and that gap closes through content volume, not dashboards.
