How does it work?
1. Check GA4's built-in AI Assistant channel
In Reports > Acquisition > Traffic acquisition, find the default channel 'AI Assistant' (ChatGPT, Gemini, Copilot…); AI Overviews and AI Mode count as Organic Search.
2. List the AI sources you see
Note session sources such as chatgpt.com, perplexity.ai, gemini.google.com, copilot.microsoft.com and claude.ai; ChatGPT search links add utm_source=chatgpt.com.
3. Create a custom channel group
Go to Admin > Data display > Channel groups > Create new channel group (Editor role needed; standard properties allow 2 custom groups).
4. Add an AI channel with regex
Add new channel 'AI tools', condition Source matches regex: chatgpt\.com|perplexity\.ai|gemini\.google\.com|copilot\.microsoft\.com|claude\.ai, then Save channel.
5. Move the channel above Referral
Expand the group, click Reorder, drag 'AI tools' above Referral, click Apply, then save the group; traffic goes to the first matching channel.
6. Verify in reports, mind the gaps
In Traffic acquisition, switch the dimension to your group and confirm AI sessions; visits from apps or copied links without a referrer land in Direct.
