# PostHog Slack app pricing - Docs

**Beta pricing**

The Slack app is in beta. Billing is usage-based through PostHog AI credits and may change as the product matures – check this page again before relying on a specific number for budgeting.

The PostHog Slack app doesn't have its own subscription. The agent that runs behind `@PostHog` mentions consumes **PostHog AI credits** for the LLM work it does. This includes tokens used when planning a task, editing files, reasoning about your data.

TL;DR: anything billable in Slack rolls up under your existing PostHog AI usage.

For credit mechanics, the free monthly tier, billing limits, and the live pricing calculator, see [PostHog AI pricing](/docs/posthog-ai/pricing.md).

## What's free

A lot of the Slack surface is just plumbing and stays free:

-   **Subscriptions** to insights and dashboards delivered to Slack channels (see [subscriptions](/docs/product-analytics/subscriptions.md)).
-   **Event-driven Slack notifications** sent via Data Pipeline destinations (see [Slack destination](/docs/cdp/destinations/slack.md)).
-   **Link unfurling** for PostHog insight and dashboard URLs.
-   The `@PostHog help`, `rules`, and `project` commands themselves – no LLM call, no credits.

## What costs credits

Anything the agent does behind an `@PostHog` mention – drafting a PR, answering a data question with the PostHog [MCP](/docs/model-context-protocol.md), summarizing a thread to spec a feature – consumes resources. The same per-token economics that apply to PostHog AI in the app apply here.

## Tracking and controlling spend

Slack-driven credit usage shows up alongside in-app PostHog AI usage in [billing overview](https://app.posthog.com/organization/billing/overview) and [billing usage](https://app.posthog.com/organization/billing/usage). PostHog sets a $150 default billing limit on PostHog AI; raise or lower it to cap spend across both surfaces at once – there's no separate cap for the Slack app.
