New here? How to read the index
Full methodology →We ask AI what Filipinos ask
Every week, the same everyday questions — “which bank is best for savings?” — go to 7 AI assistants.
We count which brands they name
Share of AI voice is how often a brand comes up in those answers: 60% means it was named in 6 of every 10. Weekly moves are in points: 40% → 45% is +5 pts.
Higher means more visible — not better
It is not a rating or a market share. One answer can name several brands, so the shares don’t add up to 100%.
Trend
Weekly visibility index, last 30 days
Weekly combined share of AI voice for the top brands. Each point is dated with the Monday that opens the week and carries the last measurement taken during that week. The underlying measurement only moves weekly, so plotting every calendar day would just repeat the same reading. Points are real measurements joined by straight lines; nothing between them is interpolated or smoothed.
Share of AI voice on industry questions, top 7 brands; the top 5 are drawn until you ask for the rest.
Share of AI voice
Who AI names first
in hospitals & healthcare
Share of AI voice is the share of measured AI answers in this category that mention the brand, combined across assistants. One answer can name several brands, so these are relative weights, not parts of 100%. Weekly change is in points: a brand going from 40% to 45% is +5 pts.
How we measure →Industry questions are the curated questions Filipinos actually ask when choosing in this category — the index’s headline ranking. The full prompt database is every tracked AI prompt that touches the category: broader, but it includes off-topic questions.

Position
Who owns
the conversation
Every measured answer in this category falls into exactly one bucket per brand: the brand named alone, named alongside rivals, rivals named without it, or no tracked brand named at all. Because the four always sum to the same total, every brand is measured against one shared denominator.

Tone
How assistants talk
about each brand
Every time an answer names a tracked brand, that sentence is classified automatically as positive, neutral, negative or mixed, and tags what it is about — price, reputation, service and so on. We count those classifications and publish the counts; we do not grade brands ourselves, and tone never enters the ranking. One answer can mention a brand several times, so mentions outnumber answers.
