Open WebUI · Memtro

Open WebUI gives your team a full chat interface on top of Memtro, with multi-user accounts, history and file uploads, while Memtro provides the memory, the connectors and the model routing.

Connect Open WebUI to Memtro

Create a Memtro API key on Dashboard → API keys. One key per Open WebUI user is best, so memory and connections stay per person; a shared key works for a quick start.
In Open WebUI: Admin Panel → Settings → Connections → OpenAI API. Add a connection:
- URL: https://platform.memtro.com/v1
- Key: sk-memtro-…
Save. The model list fills with auto, memtro, auto/anthropic, anthropic/claude-opus-5, claude-code/opus and the rest.

Recommended defaults

Set the default model to auto. Users who want agent mode pick auto:agent or put memtro.mode in a preset.
Leave streaming on. Agent progress arrives as reasoning_content, which Open WebUI renders as a collapsible "Thinking" block above the answer.
Increase the request timeout for agent runs, which can take a few minutes.

Per-user keys

For personal memory and personal connections, give each user their own Memtro key: in Open WebUI each user can add their own connection under Settings → Connections (if the admin allows it). Facts learned from a user's conversations then follow Memtro's scope rules: organisation knowledge is shared, personal preferences stay with the user.

Things to know

Memtro's tools run on the server; Open WebUI's own tool/function features are separate and can be combined.
Model ids with a slash are fine in Open WebUI. compat:<label>/<model> ids work too.
