Radar
Also known as: Radar by Pixelmojo, AI Visibility Platform, AI Visibility DIY Platform
AI visibility platform that audits what ChatGPT, Claude, Gemini, and Perplexity say about your brand, and surfaces the hallucinations and misattributions buyers are seeing in production AI answers. Most tools track whether you are mentioned. Radar tracks whether what is said is accurate, then produces the corrections you need to make. Built for digital agencies whose clients ask "are we in ChatGPT?", B2B SaaS marketing teams losing organic traffic to AI search, and enterprise brand teams worried about uncontrolled AI descriptions. 13 tools run in parallel inside Radar (plus standalone YouTube Brand Monitor and AI Open Graph Auditor at /tools/*). Free tier (6 tools, technical readiness layer): AI bot crawl check, robots.txt analyzer, llms.txt validator, schema markup audit, AEO page auditor, AI Readiness score. Paid tier (7 more tools, LLM-powered layer): citation tracker across ChatGPT/Claude/Gemini/Perplexity, Reddit brand monitor, hallucination detection with severity scoring, prompt SOV vs competitors, source influence map, answer engine per-page citation testing, brand disambiguation check (detects when AI engines link your brand name to the wrong entity). Pricing: two free entry points, individual web tools at /tools (each gated by email + 6-digit OTP, 1 audit per (email, tool), 24h credit, free) and the full /platform free check (verify your email and domain, preview all 13 tools with the 6 technical readiness tools scored and the 7 AI-response tools locked, then unlock every finding and fix prompt plus dashboard access for a one-time $5). Paid: audit packs from $5 single / $12 Starter Pack / $40 Power Pack, Pro Retainer $199/mo for 40 audits with weekly pulse re-scans on watched domains. Generates cross-tool insights with A-F grade scoring, LLM-based sentiment analysis, per-provider narrative summaries, locale/geography targeting, trend tracking, and prioritized action items. Action-first dashboard: top 3 priority fixes shown as hero above metrics. LLM Answer Diff (Pro): side-by-side comparison of how AI models describe your brand between scans, with citation flip detection, sentiment shift hierarchy, and competitor displacement tracking. DIY implementation features: AI prompt generator per action item (copy into Claude/ChatGPT/Cursor), 6 implementation threads (Crawlability, Structured Data, LLM Communication, Content Authority, AI Answer Optimization, Citation Visibility), llms.txt starter generator, JSON-LD schema markup generator, single-tool re-verify, and persistent progress tracking. Self-audited weekly at /labs/our-radar-report, methodology applied to Pixelmojo itself with findings published verbatim.

Common questions (2)
Why is my AI Readiness score low?
AI Readiness scores under 60 usually indicate a critical gap in one of five categories: bot discoverability, structured data, LLM communication (llms.txt), content accessibility, or cross-signal readiness. The category breakdown in your Radar audit identifies which one is dragging the unified score down.
How much does an AI visibility audit cost?
AI visibility audits range from free to a few hundred dollars per month. Radar starts at $0 for technical readiness tools, $5 for a single full audit, and $199/month for a Pro Retainer with weekly re-scans. Subscription competitors like AthenaHQ ($295/mo) and Gauge ($99/mo) sit at the higher, monitoring-only end.
