Authoritas

Authoritas is the UK entry in AI visibility, and it is the one to look at if you operate across markets. It tracks brand mentions, sentiment and visibility across roughly twenty selectable models: ChatGPT and GPT-5, Google AI Overviews and AI Mode, Bing AIO, Gemini, Claude, DeepSeek and Perplexity among them, which is a wider published list than most of this tier, and includes Bing AIO, which nothing else in this catalogue names. More usefully, it states that it tracks how AI responses vary by location and by language. That is the capability multilingual brands keep asking for and rarely find documented; worth noting that Authoritas makes this claim on its own homepage, while the competitor most often credited with language depth publishes no language claim at all. Pricing is public and credit-based: a free tier with 50 prompt credits a month, then £89, £229 and £379 for 2,000, 6,000 and 15,000 credits, with three Enterprise steps reaching £2,409 for 125,000. Credits cost 1 to 5 per query depending on the model, annual billing gives a month free, and you can pay in pounds, dollars or euros. It sits alongside a conventional SEO platform from £99 and a usage-priced API, so it can serve as one supplier rather than three. Customers include Allianz, Michelin, CDiscount and Lands' End.
