+# Perplexica
+
+Run [Perplexica](https://github.com/ItzCrazyKns/Perplexica), a privacy-focused AI search engine, in your Coder workspace. Supports cloud providers (OpenAI, Anthropic Claude) and local LLMs via Ollama.
+
+```tf
+module "perplexica" {
+  count    = data.coder_workspace.me.start_count
+  source   = "registry.coder.com/coder-labs/perplexica/coder"
+  version  = "1.0.0"
+  agent_id = coder_agent.main.id
+}
+```
+
+This module uses the full Perplexica image with embedded SearXNG for simpler setup with no external dependencies.
+
+![Perplexica](../../.images/perplexica.png)
+
+## Prerequisites
+
+This module requires Docker to be available on the host.
+
+## Examples
+
+### With API Keys
+
+```tf
+module "perplexica" {
+  count             = data.coder_workspace.me.start_count
+  source            = "registry.coder.com/coder-labs/perplexica/coder"
+  version           = "1.0.0"
+  agent_id          = coder_agent.main.id
+  openai_api_key    = var.openai_api_key
+  anthropic_api_key = var.anthropic_api_key
+}
+```
+
+### With Local Ollama
+
+```tf
+module "perplexica" {
+  count          = data.coder_workspace.me.start_count
+  source         = "registry.coder.com/coder-labs/perplexica/coder"
+  version        = "1.0.0"
+  agent_id       = coder_agent.main.id
+  ollama_api_url = "http://ollama-external-endpoint:11434"
+}
+```
