1. Profound — best for enterprise programs

Profound goes deepest on citation, sentiment, rank, and competitive presence in one platform, making it the choice for larger teams that need to connect source-level data to broader brand visibility across many prompts and markets. Pricing is custom/enterprise-only.

2. Peec AI — best mid-market balance

Peec pairs source-level citation detail with brand visibility data and marketing-friendly dashboards, and separates "used" sources from "cited" ones — a distinction that matters since being read by a model isn't the same as being named. Starter plans run around €85–95/month for a limited prompt set and a handful of tracked models.

3. Otterly.AI — best for getting started cheaply

At $29/month, Otterly is the most accessible entry point for continuous citation tracking, with weekly URL-level citation data and a GEO Audit that flags on-page factors hurting your odds of being cited. A reasonable first tool if you've never measured this before.

4. Ahrefs Brand Radar — best for scale and existing Ahrefs users

If you're already paying for Ahrefs, Brand Radar adds AI citation and mention tracking on top, covering an unusually large prompt index (reported in the hundreds of millions). Good if you want AI visibility sitting next to backlink and keyword data you already track.

5. Semrush AI Visibility Toolkit — best for existing Semrush users

Similar logic to Ahrefs: an add-on (roughly $99/month) that surfaces cited domains and URLs per tracked prompt inside a suite you may already run for SEO. Prompt limits are tighter than dedicated tools, but the integration with existing reporting is the draw.

Bottom line

If you're testing the waters, start with Otterly or Peec. If you're already committed to Ahrefs or Semrush for SEO, their AI modules are a reasonable bolt-on before you buy a separate tool.
