There's No Position #3 in a ChatGPT Answer
A growing share of product and service discovery now happens inside ChatGPT, Perplexity, and Google's AI answers. Those answers name two or three brands — you're either recommended or invisible, and no traditional rank tracker will tell you which. Sarphin asks the questions your customers ask, every day, and turns the verdict into a trend you can act on.
2–3
Brands named in a typical AI answer — everyone else is invisible
Daily
Automated Perplexity checks, plus ChatGPT three times a week
15
Tracked questions per brand, with competitors and cited sources
How It Works
Ask, Measure, Report — Every Day
The customer enters a brand and the questions their buyers actually ask. Sarphin runs them against live AI answer engines on a schedule and turns the results into visibility data.
Scheduled Checks from Clean Sessions
Every tracked question runs on Perplexity daily and ChatGPT three times a week, always from clean sessions so personalization doesn't skew the result. A single AI answer is an anecdote; the same question asked every day becomes a trend line — and trend is what tells you whether your content changes are working.
Mention Rate as a Metric
Each run produces a simple verdict per question — mentioned or not — rolled up into a mention rate the dashboard charts over time. Changes in AI visibility show up as movement in the trend instead of a one-off screenshot, which is exactly what agencies need to demonstrate progress to clients.
Who Appears Instead — and Why
When a brand isn't in the answer, Sarphin records which competitors were named instead and which web sources the AI cited to build its answer. Those cited sources are the actionable part: they're the pages where a mention, review, or listing would actually change the AI's output.
Competitor Tracking
Every answer is parsed for brand names, so you see exactly who owns the questions you're missing.
Cited Sources
The pages the AI actually read become a prioritized to-do list for earning a mention.
Agency-Ready Client Reports
The target customer is an SEO or marketing agency managing multiple brands. Every brand gets the full product — 15 tracked questions, competitor and source data, exportable reports — and pricing tiers down per brand as agencies add clients, so AI-visibility reporting becomes a billable line item for them.
Free Instant Scan as the Funnel
The landing page includes a no-account instant checker: enter a brand and up to three customer questions, and Sarphin runs them against a live AI answer engine on the spot. Seeing "✗ Not mentioned" next to your own brand is the demo — the 7-day free trial starts from there.
