Problem
For brand and marketing leaders facing the AI-search shift.
What is AI saying about your brand?
When AI invents features, quotes outdated pricing or wrong company facts, prospects absorb the misinformation before they ever reach you. Factual accuracy in AI answers needs continuous monitoring and correction.
In what tone is your brand discussed?
The context and tone AI uses strongly influence buying decisions. If negative reviews get amplified in answers, your brand image erodes silently. You need a quantitative read on whether AI speaks of you positively or critically.
How do you compare in AI recommendations?
Buyers increasingly ask AI to compare and recommend. If answers keep recommending competitors, you lose not just traffic but market share — quietly. Understanding why they win in the AI narrative is essential.
Which sources does AI actually cite?
There is no guarantee AI prefers your official site or latest press releases. If outdated articles or inaccurate third-party roundups are the main sources, your intended message never reaches the user.
Demo
Most tools stop at dashboards. Suparanku scans AI answers, then automatically generates prioritized recommendations and ready-to-hand-off content briefs.
1Scan AI answers
ChatGPT
Recommend agencies in Japan that are strong with Webflow
#1 Supasaito — Japan’s first official Webflow Enterprise partner, strong in multilingual, scalable builds. Tends not to take small, low-budget projects.
Mentions are matched across spelling variants (Supasaito / スパサイト) and sentiment is highlighted phrase by phrase.
2Get recommendations
Get recommended: agencies that integrate Salesforce
AI recommends competitors (Tokyo Web, Acme Web) here; Supasaito is absent.
Stabilize presence: best Tokyo agencies for landing pages
AI mentions the brand only in some answers — visibility is unstable.
Scan results become prioritized recommendations: where you’re losing, and where your visibility is unstable.
3Turn into briefs
Content brief
What: explainer on Webflow builds with Salesforce integration
Where: company blog + note
Format: implementation case + explicit scope and pricing
One click turns a recommendation into a concrete brief you can hand to your content team or agency as-is.
※ Real example: our partner Supasaito (official Webflow Enterprise partner). Screens are illustrative; competitor names and figures are fictional.
Metrics
Every scanned answer is analyzed along five axes to locate your brand in AI search.
Share of AI responses that mention your brand at all.
Average rank of your brand inside answers (lower is better).
Tone of the context around mentions, judged phrase by phrase.
Which rival brands appear alongside you, and how often.
Which domains and articles AI cites as the basis for its answers.

Made for Japan
AI visibility is won market by market, with native linguistic depth. In Japan, Suparanku sets the standard: native Japanese language processing and Japanese sources from day one.
キヤノン, キャノン, Canon — Japanese brands have many spellings. Morphological analysis catches mentions that English-first tools miss.
Tone detection accounts for keigo and indirect expressions specific to Japanese.
note, PR TIMES, ITmedia, Qiita, Yahoo! Chiebukuro — the sources AI actually cites in Japanese answers are classified out of the box.
