Ollama

Run a model locally with no API key and no data leaving your premises.

Prerequisites:

Ollama installed and running (ollama serve)
At least one model pulled, e.g. ollama pull llama3.1

Setup:

Preset: Ollama
Adjust the endpoint in case it's needed. The default endpoint is http://localhost:11434/v1
No key required; the field is hidden
Type your model name (the model list isn't auto-fetched for Ollama); e.g. llama3.1
Test Connection, Apply

TIP

If Ollama rejects the request, enable Use old /chat/completions endpoint in Settings → Advanced; some Ollama versions don't implement the Responses API (/responses).

Browser CORS

OpenDocBot runs in the browser, so requests to Ollama must come from an origin the Ollama server allows. Ollama only accepts the origins listed in the OLLAMA_ORIGINS environment variable (default: localhost,127.0.0.1,0.0.0.0).

The Office taskpane loads the add-in as a page from a specific URL, and all requests to Ollama are made from that page. So Ollama sees that page's origin, not localhost. What to set depends on how the add-in is served:

Hosted instance: the app is served from https://opendocbot.com/app, so the origin Ollama sees is https://opendocbot.com. Restart Ollama with:

bash

export OLLAMA_ORIGINS="https://opendocbot.com"
ollama serve

Self-hosted: use the hostname/IP/domain of your OpenDocBot instance (the origin shown in the taskpane's address bar). For example, serving the add-in from https://localhost:3000:

bash

export OLLAMA_ORIGINS="https://localhost:3000"
ollama serve

You can list multiple origins, comma-separated: OLLAMA_ORIGINS="https://opendocbot.com,https://localhost:3000".

Shared, central, or key-protected Ollama server

The default endpoint is localhost for a single machine. Ollama can also run on a shared or central server (it binds 0.0.0.0 and exposes an OpenAI-compatible /v1 API). If that's your case, select the Ollama preset and change the Endpoint URL to the server's address, e.g. http://ollama-server:11434/v1.

If your Ollama server requires an API key (e.g. OLLAMA_API_KEY is set), select the Custom preset instead, set the Endpoint URL to the Ollama server's address, and paste the key in the API Key field. OpenDocBot sends it as an Authorization: Bearer header, which Ollama validates.
