Do AI assistants actually pick your app?
Vritax measures how ChatGPT, Claude and other assistants surface and select apps, connectors and tools — and shows builders what to improve.

How it's measured
Observed behaviour, not self-reported claims.
01
0 claims
Read from real assistant behaviour
Every result comes from watching what an assistant surfaces and selects for a prompt. Nothing is taken from a vendor's own description of its integration.
02
Repeated
Repeated runs, bias controlled
Prompts are repeated across phrasings, orderings and sessions. Position and naming effects are rotated out so a single lucky run never becomes a finding.
03
Directional
Reports state direction, not certainty
Each report says which way a signal moves and how thin the evidence is. Assistants change weekly; a number without a date is worthless.
Research log
One description change, and a published ChatGPT app lost the first call in 9 of 10 chatsTwo flight-search tools live in the same ChatGPT conversation, one fixed request, 40 fresh chats. Changing nothing but the test connector's tool description moved the host's first call from 0 of 10 to 9 of 10, back to 0 when I put the old text back, and to 9 again with a description a real publisher could ship.Read the report →
