The free LLM ranking tool that scans your domain across ChatGPT, Claude, Perplexity, and Gemini using 24 query variants — and tells you exactly where you stand.
<\!-- Domain input form -->No account required. Free forever.
Type your domain name. We handle the rest — no login, no setup, no credit card.
Our scanner submits 24 category, comparison, and use-case queries to ChatGPT, Claude, Perplexity, and Gemini — the queries your customers are actually asking.
Your results arrive in ~60 seconds: overall AIS score, per-engine breakdown, citation gaps, and actionable quick wins.
Your composite visibility score across all 4 LLM engines, weighted by Visibility (40%), Authority (30%), Sentiment (20%), and Accuracy (10%).
Separate scores for ChatGPT, Claude, Perplexity, and Gemini. See which engines cite you and which ignore you entirely — they behave very differently.
The 5 specific queries where you are most likely absent from LLM answers — sorted by the estimated impact of closing each gap on your AIS score.
Specific, actionable content or technical improvements you can implement this week to improve your citation rate — prioritized by ease and impact.
The free scan is a snapshot. Scale is the engine that compounds your visibility over time.
See all 24 citation gaps — not just the top 5. For each gap, we show which competitor is currently cited instead of you and a specific content brief to close it.
Our AI agent drafts citable content assets for your highest-priority gaps — structured for LLM extraction with methodology sections, specific data, and proper authorship markup.
Scans run automatically each month. Your dashboard shows month-over-month AIS score changes per engine — so you see exactly which content moves are driving citation gains.
Every asset we generate for you is added to your library. The library compounds — each new asset increases citation probability across related queries, not just the one it was built for. After 18 months, it becomes a durable LLM-citation moat.
We use 24 query formulations covering category queries ("best tools for [X]"), comparison queries ("[your brand] vs alternatives"), use-case queries ("how to [do specific task in your category]"), and brand-specific queries. The mix is calibrated to your domain's category based on your homepage content.
Typically 45–90 seconds. We run queries in parallel across all 4 engines with a 30-second per-engine timeout. If one engine is slow, the others continue in parallel so the overall time stays predictable.
The AIS score is representative, not exhaustive. We run 24 query variants per engine as a statistically significant sample of the query space your customers use. The score will not be identical if you run it twice — LLM outputs have natural variance — but the relative position (low/mid/high) and the gap identification are highly consistent.
No. The free scan requires only a domain name. You can optionally enter an email address to receive a full report PDF. Creating an account unlocks scan history and the Scale plan dashboard.
SEO tools measure search engine ranking signals — keyword positions, backlink counts, technical crawl health. AISearchStackHub measures LLM citation signals — citation rate, authority tier, and sentiment in AI assistant answers. These are different channels, different mechanics, and different improvement strategies. Most SEO tools have no LLM coverage at all.
74% of brands score below 40/100. Find out where you stand — it takes 60 seconds and requires nothing but your domain name.
