# Demos & examples - Docs

Explore real-world examples of LLM analytics in action. These projects demonstrate different ways to integrate PostHog's LLM analytics features.

## Example projects

### LLM Analytics Apps

Interactive CLI showcasing PostHog LLM analytics across 13+ AI providers (Anthropic, OpenAI, Google, LangChain, and more). Great for understanding how different SDKs integrate with PostHog. We use this mainly to help with development, debugging, and reproduction of user issues.

-   **GitHub:** [PostHog/llm-analytics-apps](https://github.com/PostHog/llm-analytics-apps)

### GitHub Standup Agent

Multi-agent standup summarizer using OpenAI Agents SDK. Demonstrates automatic agent tracing with `posthog.ai.openai_agents.instrument()`.

-   **GitHub:** [PostHog/github-standup-agent](https://github.com/PostHog/github-standup-agent)
-   **Integrations:** [OpenAI Agents SDK](/docs/llm-analytics/installation/openai-agents.md)

### Andy's Daily Factoids

Full-stack AI factoid generator demonstrating [LangChain callbacks](/docs/llm-analytics/installation/langchain.md), multi-platform observability, cost tracking, and real-time streaming. Also uses [OpenRouter](/docs/llm-analytics/installation/openrouter.md) for LLM calls.

-   **GitHub:** [andrewm4894/andys-daily-factoids](https://github.com/andrewm4894/andys-daily-factoids)
-   **Integrations:** [LangChain](/docs/llm-analytics/installation/langchain.md), [OpenRouter](/docs/llm-analytics/installation/openrouter.md)

### Repo Stalker

GitHub PR/issue AI assistant with custom span tracking for different interaction types (chat, summaries, analysis). Built with Lovable using [manual capture](/docs/llm-analytics/installation/manual-capture.md).

-   **GitHub:** [andrewm4894/repo-stalker](https://github.com/andrewm4894/repo-stalker)
-   **Integrations:** [Manual capture](/docs/llm-analytics/installation/manual-capture.md)

### Plot Agent

AI data visualization assistant using [LangGraph](/docs/llm-analytics/installation/langgraph.md). Shows PostHog callback integration with conversation session tracking.

-   **GitHub:** [andrewm4894/plot-agent](https://github.com/andrewm4894/plot-agent)
-   **Integrations:** [LangChain](/docs/llm-analytics/installation/langchain.md), [LangGraph](/docs/llm-analytics/installation/langgraph.md)

### Anomaly Agent

LLM-powered anomaly detection for time series data using [LangGraph](/docs/llm-analytics/installation/langgraph.md). Demonstrates multi-step AI workflows with verification.

-   **GitHub:** [andrewm4894/anomaly-agent](https://github.com/andrewm4894/anomaly-agent)
-   **Integrations:** [LangChain](/docs/llm-analytics/installation/langchain.md), [LangGraph](/docs/llm-analytics/installation/langgraph.md)

### HogFlix (PostHog Demo 3000)

Full PostHog feature showcase including LLM chat with both [LangChain](/docs/llm-analytics/installation/langchain.md) and direct [OpenAI](/docs/llm-analytics/installation/openai.md) integration patterns.

-   **GitHub:** [PostHog/posthog-demo-3000](https://github.com/PostHog/posthog-demo-3000)
-   **Integrations:** [LangChain](/docs/llm-analytics/installation/langchain.md), [OpenAI](/docs/llm-analytics/installation/openai.md)

### Emoji Hero

Chat-powered custom emoji generator for Slack. Users describe what emoji they want, and a [Pydantic AI](/docs/llm-analytics/installation/pydantic-ai.md) agent searches for images, applies customizations (text overlays, cropping), and optimizes them for Slack. Uses OpenRouter as the LLM provider with OpenTelemetry traces sent to PostHog, and links frontend/backend sessions via `posthog-js`.

-   **GitHub:** [andrewm4894/emoji-hero](https://github.com/andrewm4894/emoji-hero)
-   **Live:** [emoji-hero.com](https://emoji-hero.com)
-   **Integrations:** [Pydantic AI](/docs/llm-analytics/installation/pydantic-ai.md), [OpenRouter](/docs/llm-analytics/installation/openrouter.md)

### Hot Hog on a Bicycle

Human vs AI hot dog SVG prompt battle built for [AI Engineer Europe](https://www.ai.engineer/europe). Demonstrates end-to-end LLM analytics instrumentation including traces, spans, prompt management, evaluations, and linked session replay.

-   **GitHub:** [andrewm4894/hot-hog-bicycle](https://github.com/andrewm4894/hot-hog-bicycle)
