Briefsy is an AI market analyst built for local businesses and the agencies that serve them. It watches your client's website, their competitors, their reviews, their Google Business Profile, and their visibility inside AI search engines like ChatGPT, Perplexity, and Gemini. Then it delivers a prioritized brief of what changed and what to do next. That last part matters. Most monitoring tools hand you a dashboard and wish you luck. Briefsy tells you which competitor just ran a promotion, which review needs a response, and where your client dropped out of AI answers. For agencies managing multiple local clients, the workflow is simple. You onboard a workspace, connect the client's properties, and Briefsy starts watching. The snapshot reports give you a clean starting point for pitches. The competitor tracking shows you exactly where the gaps are. The outreach drafts save your team from staring at a blank page when a client needs a response. Briefsy also checks AI search visibility across ChatGPT, Perplexity, and Gemini, which is increasingly where local buyers start their research. If you run local SEO or reputation management for service businesses, Briefsy covers the signals that actually move revenue: Google Business Profile activity, review sentiment, competitor moves, and AI search presence. It's self-serve SaaS, so you can spin up a new client workspace without a sales call.

Best for: Local SEO agencies, reputation management firms, and multi-location businesses that need to monitor GBP, reviews, competitors, and AI search visibility in one place.

Profound is an agentic marketing platform that tracks how brands appear in AI answers and then helps you fill the gaps. According to their website, Prompt Volumes runs on more than 1.9 billion real user prompts, broken down by intent and demographics like age, income, and region. That's a massive data set. Answer Engine Insights tracks visibility, citation share, accuracy, and sentiment across every major engine and competitor. For agencies, Profound offers Agency Mode with client workspaces and pitch environments. You can pull up a prospect's AI visibility live on a sales call and promote that pitch into a full account when the contract lands. The platform also includes content creation workflows, so you can go from identifying a gap to publishing content that fills it. Profound is well-funded and moves fast. The trade-off is complexity. This is not a lightweight tool. It's built for agencies running AEO as a scaled service across many clients. If you only need a simple visibility score, Profound is overkill. But if you're building a repeatable AI visibility practice, the depth is there.

Best for: Agencies running AEO as a scaled service across many clients, and teams that need to prove AI visibility impact before signing a contract.

Starter at €85/month (50 prompts, 3 models); Pro at €199/month (100 prompts, 5 countries); Enterprise at €499/month (300+ prompts, 10+ countries). Add-ons available for additional models.

Peec AI is a dedicated AI visibility tracker built by ex-Google and DeepMind engineers. According to their website, it monitors 300+ prompts daily across ChatGPT, Perplexity, Claude, and Gemini. The platform shows you citation source mapping, so you can see exactly where AI pulls information about your brand. Multi-country tracking is available for international clients, and competitor benchmarking includes sentiment tracking. Unlimited team seats are included on all plans, which is unusual and useful for agencies with large teams. Peec AI is known for clean, trustworthy reporting with daily tracking and screenshot audit trails. That audit trail matters when you need to prove to a client that a mention actually happened. The platform is monitoring-only, so you'll need a separate tool for content creation or optimization. Pricing starts at €85/month for the Starter plan, which includes 50 prompts and 3 models. The Pro plan is €199/month for 100 prompts and 5 countries. Enterprise starts at €499/month for 300+ prompts and 10+ countries. Additional models are available as add-ons.

Best for: Agencies that want clean, trustworthy AI visibility reporting with audit trails and multi-country support.

Starts at $29/month for the Lite plan (15 prompts). Standard plan and add-ons available for more engines and prompts.

Otterly AI is one of the most affordable ways to start tracking AI visibility. According to their website, the Lite plan starts at $29/month for 15 prompts. It's a focused tool that monitors brand mentions and citations across major AI platforms, with GEO audits that give you actionable recommendations. The platform suggests LLM prompts based on your SEO keywords, which helps you get started without guessing. Otterly has a partner program with workspace management and a directory, so agencies can manage multiple clients and get listed for inbound leads. It's recognized as a Gartner Cool Vendor for AI in Marketing and a G2 High Performer. The trade-off is depth. Otterly doesn't offer real prompt-volume data or in-platform content generation. Engine coverage is limited on lower tiers, with Claude and Gemini available as paid add-ons. For agencies just starting to offer AI visibility as a service, Otterly is a low-risk entry point. For teams that need enterprise-grade analytics or content workflows, you'll outgrow it quickly.

Best for: Solo marketers and small agencies starting out with AI visibility tracking on a budget.

Starter plan at $295/month. Enterprise pricing available.

AthenaHQ is a mid-market GEO platform that turns visibility data into prescriptive next steps. According to their website, the Action Center gives you clear recommendations based on your AI visibility data. It tracks visibility across 8 AI engines on all plans, with credit-based pricing. The platform includes GA4 attribution, so you can connect AI mentions to actual website traffic. For agencies, AthenaHQ offers unlimited seats and a partner program that refers qualified leads by focus area. That's a real differentiator if you want inbound leads, not just a discount. The platform also includes content generation, though the AI content often needs heavy editing. Prompt volume relies on an undisclosed model, which is a transparency gap. Pricing starts at $295/month for the Starter plan. For agencies that want a balance of visibility tracking, action recommendations, and lead generation, AthenaHQ is worth a look. Just be prepared to edit the AI-generated content before it goes to clients.

Best for: Agencies that want inbound leads referred to them and prescriptive action recommendations from their AI visibility data.

Starter at $97/month, Agency at $297/month, Agency Pro at $497/month. Annual plans available at $970, $2,970, and $4,970 respectively.

Rankability is built for agencies that need to track, diagnose, and improve client visibility across both traditional SEO and AI search. According to their website, it's designed around the full workflow: tracking visibility, diagnosing gaps, researching opportunities, creating content, auditing pages, and turning insights into action. The platform includes tools called Serena, Researcher, Copywriter, Auditor, and Tracker inside one dashboard. It tracks AI search visibility across 11 AI platforms, with query allowances of 100, 300, and 500 depending on your plan. All paid plans include unlimited client workspaces, unlimited team members, branded reports, and API/MCP access. Pricing starts at $97/month for Starter, $297/month for Agency, and $497/month for Agency Pro. Annual plans are also available. The trade-off is that AI visibility is keyword-configured, not built on real prompt demand. If you want to track actual user prompts, you'll need a different tool. But for agencies that want SEO and AI visibility in one workflow, Rankability is a strong fit.

Best for: SEO agencies, digital marketing agencies, freelancers, and consultants who want AI visibility tracking tied directly to SEO execution.
