As answered by people managing Codewars and Linksii.
Linksii's answer:
Linksii is the only AI brand visibility platform that tells you what to do, not just what's happening. While competitors like Peec.ai and Otterly show you monitoring data, Linksii provides actionable recommendations — specific steps to improve your visibility across ChatGPT, Claude, Gemini, and Perplexity. All 4 AI platforms are included on every plan (competitors charge extra per platform), and pricing starts at $89/mo with no hidden add-on costs. Built for marketing teams and agencies who need to understand how AI search is reshaping brand discovery.
Linksii's answer:
Three reasons. First, every plan includes all 4 major AI platforms — ChatGPT, Claude, Gemini, and Perplexity. Competitors like Peec.ai only include 3 and charge $20-30/month extra for each additional platform. Second, Linksii doesn't just monitor — it gives you specific, actionable recommendations on how to improve your AI visibility. This is the number one complaint across every competitor's reviews: "tells me what's happening but not what to do about it." Linksii solves that. Third, transparent pricing from $89/month with no credit-per-query gotchas, no platform add-on fees, and unlimited team seats on every plan. Competitors like Profound start at $99/month for ChatGPT only, and Scrunch AI charges $300/month per brand with unpredictable credit consumption.
Linksii's answer:
Marketing teams, SEO professionals, and digital agencies who need to understand how their brands appear in AI-powered search. Specifically: mid-market companies ($5M-$500M revenue) whose customers are increasingly using ChatGPT, Claude, Gemini, and Perplexity instead of Google to research products, services, and providers. Also agencies managing AI visibility for multiple client brands — one agency account can monitor 5-50 brands. The common thread is that these teams are seeing organic traffic decline and need to understand the AI search channel that's replacing it.
Linksii's answer:
Linksii was born from a simple realisation: the way people discover brands is fundamentally shifting, and most businesses have no idea it's happening. Organic search traffic has dropped 27% year-over-year for many brands, while AI referral traffic has tripled. Millions of people now ask ChatGPT "what's the best CRM for agencies?" or "which accounting firm should I hire?" instead of searching Google. If your brand isn't in those AI-generated answers, you're invisible to a growing share of your market — and you don't even know it. We built Linksii to fix that blind spot. Not just another monitoring dashboard, but a platform that shows you exactly how AI sees your brand, where the gaps are, and what to do about it. Because knowing your visibility score is 42 is useless unless someone tells you how to make it 70.
Linksii's answer:
Next.js, React, TypeScript, Tailwind CSS, Supabase (PostgreSQL + Auth), Stripe for billing, and Sanity CMS for the blog. AI integrations are built directly on the Anthropic (Claude), OpenAI (ChatGPT), Google (Gemini), and Perplexity APIs.
