# Perplexity AI

The `robomotion perplexity` CLI connects to Perplexity AI for search-augmented AI responses. It provides chat completions grounded in real-time web data with source citations, combining LLM reasoning with live search results.

## When to use
- Search the web with AI-powered answers and citations
- Run chat completions with real-time web data grounding
- Get up-to-date factual responses backed by sources

## Prerequisites
- `robomotion` CLI installed
- Package installed: `robomotion install perplexity`
- Perplexity API key configured via Robomotion vault

## IMPORTANT: Session Mode Required for Multi-Step Operations
Each CLI command runs as a **separate process** — connection IDs from `connect` do NOT persist across calls.
You MUST use `--session` on `connect` and pass `--session-id` to all subsequent commands.

## Workflow
1. Install (once): `robomotion install perplexity`
2. Connect with session:
   ```
   robomotion perplexity perplexity_connect --session --output json
   # → {"outClientId":"<client-id>","session_id":"<session-id>"}
   ```
3. Use the returned `client-id` and `session-id` in all subsequent commands:
   ```
   robomotion perplexity perplexity_chat --client-id "<client-id>" --messages <json> --session-id "<session-id>" --output json
   ```
4. Disconnect when done:
   ```
   robomotion perplexity perplexity_disconnect --client-id "<client-id>" --session-id "<session-id>" --output json
   ```

**Always** append `--output json` to get structured JSON results.
