AI Taxonomy

Manage the list of AI tools your classifier recognises as traffic sources.

Free

The AI Taxonomy is a list of domains — one per AI tool — that the classifier uses to identify traffic arriving from AI chat interfaces. When a visitor follows a link your content produced in a conversation with ChatGPT, Claude, or Perplexity, the referrer domain matches a taxonomy entry and that session gets classified as AI Referrer rather than falling through to Referral or Direct.

Default entries

The app ships with 11 pre-configured entries covering the most common AI tools:

DomainLabel
chat.openai.comChatGPT
chatgpt.comChatGPT
gemini.google.comGemini
claude.aiClaude
perplexity.aiPerplexity
copilot.microsoft.comMicrosoft Copilot
bing.com/chatBing Chat
you.comYou.com
phind.comPhind
character.aiCharacter.AI
poe.comPoe

Adding your own entries

New AI tools launch regularly. When you notice a referrer in your Reports that looks like an AI tool but isn't being classified as one, add it here.

  1. Go to AI Taxonomy in the console
  2. Enter the domain in the Domain field — use just the hostname, no https:// prefix (e.g. newai.example.com)
  3. Enter a human-readable name in the Label field (e.g. NewAI)
  4. Click Add entry

New entries apply to incoming sessions immediately. They don't retroactively reclassify sessions already in the database — those keep their original classification.

Deactivating and deleting entries

Each entry has an active/inactive toggle. Deactivating an entry stops it being checked by the classifier without removing it — useful if an AI tool has shut down and you don't want to lose the record of it. Deleting removes it permanently.

Default entries (the ones that shipped with the app) can be deactivated or deleted just like your own. If you delete a default entry and want to restore it, the Reset to defaults button adds back any missing defaults without touching entries you've created or modified.

CSV export

The Export CSV button downloads your full taxonomy as a CSV file, useful for auditing or sharing with a colleague who manages a separate install.
