Notra is a Generative Engine Optimization (GEO) platform built for marketing teams and founders who want to know whether AI assistants recommend their brand when buyers ask for solutions. Instead of guessing, it runs your chosen prompts against ChatGPT, Claude, Gemini, and Perplexity with live web search enabled, then stores the full answers so you can see exactly what each engine said, where your brand appeared, and which competitors took the spots you didn't.

The dashboard tracks four core metrics:

• Mention rate by engine shows what percentage of scans included your brand, your average list position, and how both have shifted since the last run.
• Share of voice maps which brands get named when you don't, broken down per prompt, language, and engine. You add competitors and their common misspellings, and Notra handles the rest.
• AI traffic attribution separates crawler fetches from genuine citations and human referrals. A bot indexing your site for training isn't the same as an assistant citing your page while answering a buyer, and Notra labels them differently across 66 known AI agents.
• Content gaps surfaces the prompts where engines answer without mentioning you, ranked by how winnable each opportunity looks. Pick a gap and the built-in writer drafts a guide, listicle, or comparison using your brand identity, sitemap, and competitor data.

Every scan stores the complete engine response, not just a score. You can open any prompt, read the full answer, see which pages the engine cited, and even send a follow-up in the thread to test whether your recommendation survives a buyer pushing back.

Traffic tracking works without a script tag. It runs as middleware in Next.js, Nuxt, Astro, TanStack Start, or SvelteKit, and human traffic is dropped before anything is stored. Zero data retention is available as an add-on for teams with compliance requirements, restricting scans to model providers that support ZDR.

Plans are tiered by the number of AI answers tracked per month, starting at 2,000 on Starter and scaling to unlimited on Enterprise.

Ansvisor is an AI visibility tracking platform built for marketing, SEO, content, and brand teams who need to understand how their brand shows up in AI-generated answers. As AI search engines handle billions of queries daily, appearing in those answers matters as much as ranking in traditional search. Ansvisor connects that gap between conventional search data and AI-specific behavior.

It monitors brand mentions, citations, and visibility scores across ChatGPT, Google AI Overviews, Google AI Mode, Gemini, Claude, Perplexity, and Microsoft Copilot. You can track competitor performance on the same platforms, identify which prompts and topics are driving AI-referred traffic, and measure how visibility changes over time.

Key capabilities include:

• Prompt Intelligence: Tracks the specific prompts and questions where your brand does or doesn't appear, surfacing gaps worth acting on.
• Opportunity Discovery: Finds high-value topics across AI and traditional search data where your brand could gain citations or mentions.
• Action Center: Converts visibility data into prioritized briefs and content workflows your team can execute directly.
• Traffic Attribution: Connects AI visibility metrics to actual site traffic and business outcomes, so you can see what's driving real results.
• Competitor Tracking: Monitors how rivals appear across the same AI platforms, including citation frequency and mention sentiment.

Unlike tools that only report on visibility, Ansvisor is built around an end-to-end workflow: Analytics → Opportunities → Actions. That makes it useful beyond SEO specialists. Brand managers, PR teams, agencies, and executives can all work from the same data. Compared to alternatives like Otterly.AI, AthenaHQ, or Profound, Ansvisor's open-source foundation means teams can self-host the platform at no cost, audit its data handling, and extend it for custom workflows.

It's built by 50+ GitHub contributors and available as a self-hosted deployment or via Ansvisor Cloud with a 14-day free trial on paid plans.
