OTW Signal vs rating.so: which is better? (2026)

OTW Signal

Measure whether ChatGPT, Gemini, Claude, and Perplexity recommend your business, with the evidence behind every number.

Domain verified Dofollow

Your customers now ask AI assistants who to buy from, and most businesses have no idea what ChatGPT, Gemini, Claude, and Perplexity say about them. OTW Signal answers that question with real measurement instead of a guess. One AI answer is a coin flip: ask the same question twice and you get different names. So OTW Signal asks every buyer-intent question 8 times per engine and reports your true AI mention rate with a 95% confidence interval. What you get: - Your AI Visibility Score, measured, not estimated - Which competitors AI recommends instead of you, and how often - The raw AI answers as receipts, so every claim is verifiable - Prioritized fixes to improve how AI understands and cites your business - Optional weekly tracking dashboard to watch your score move as you ship fixes Who it's for: founders, marketers, and SEO/GEO consultants who want a defensible number, not a black-box grade. Agencies can also pull scores programmatically through the data API. Run a free analysis in about 30 seconds. The full evidence-linked report is $3.99, no subscription required.
