What do I need to connect PostHog to LLM Pulse?

You need a PostHog personal API key (it starts with phx_) and your numeric project ID. Generate the key from your PostHog user settings with read access. The key inherits your permissions, so you do not need to grant LLM Pulse anything beyond what you already have.

Where do I find my PostHog project ID?

Open PostHog and go to Settings then Project. The numeric project ID is shown there, and it is also the number in your project URL. Paste it into the connect form. A friendly project name is optional.

Can I use EU Cloud or a self-hosted PostHog instance?

Yes. The advanced section accepts a custom HTTPS base URL for self-hosted PostHog, and the form lets you pick US Cloud or EU Cloud. We enforce HTTPS so your API key never travels over an unencrypted connection.

Which AI assistants do you detect in PostHog data?

We track every major AI assistant, including ChatGPT, Perplexity, Gemini, Claude, Copilot, Grok, Mistral, Meta AI and DeepSeek, by matching the referring domain on your pageview events with a HogQL query. Organic search is matched separately so we can plot AI versus organic versus other traffic.

Can I filter conversions with PostHog?

PostHog connections report users and sessions by AI source, but conversion-event filtering is not available for PostHog, so it reports zero conversions. If conversion attribution matters, connect Google Analytics 4, Piano Analytics or Adobe Analytics instead, which all support conversion-event filtering. PostHog measures AI referral traffic, not AI crawler-bot hits.

Which LLM Pulse plans include the PostHog integration?

The PostHog integration is included on Growth and above. Enterprise customers using whitelabel can connect a PostHog project per LLM Pulse project.

Features

All your PostHog pageviews, finally surfaced for AI

Bring Your Own API Key

Connect with a PostHog personal API key and your numeric project ID. No OAuth and no extra users to invite, just paste the key that starts with phx_ and your project ID and you are live.

HogQL Across Every AI Assistant

We run a single HogQL query over your pageview events and match the referring domain against ChatGPT, Perplexity, Gemini, Claude, Copilot, Grok, Mistral, Meta AI and DeepSeek, with no insights or dashboards to build in PostHog.

Any PostHog Deployment

Choose US Cloud or EU Cloud, or paste the HTTPS URL of your self-hosted PostHog instance in the advanced section. We route every query through the region you select.

No Insights to Maintain

Instead of building and sharing PostHog insights, we query your event data directly with HogQL so the AI breakdown stays accurate even as your event schema evolves.

Read-Only, Revocable

Use a personal API key scoped to query reads. Rotate or delete the key in PostHog and the connection disconnects cleanly, we never write to your project.

395 Days Backfill

On first connect we pull up to 395 days of pageview history so you can see when ChatGPT, Perplexity and Gemini started sending visitors to your PostHog-tracked site.
