Use CircuitNotion in TypingMind

TypingMind is a chat interface you can point at any OpenAI-compatible API. This guide adds your CircuitNotion API key so you can chat with CircuitNotion's models — and the OpenAI, DeepSeek, Anthropic, and Moonshot models it routes to — without writing any code.

Steps

Four steps, no code

  1. Step 1

    Get a CircuitNotion API key and add credits

    Sign in to the Developer Platform, open Generate API Key, and copy the key that starts with cn_ — it's shown only once. Then add credits so requests don't get rejected.

    Generate API KeyAdd credits

  2. Step 2

    Open TypingMind and find "Add Custom Model"

    In TypingMind, open the Models section from the sidebar (or the Settings gear) and choose Add Custom Model. TypingMind occasionally renames or moves this — if the label looks different, look for anything mentioning a "custom" or "OpenAI-compatible" model, or check TypingMind's own docs for the current location.

  3. Step 3

    Fill in CircuitNotion's details

    Use these exact values. Paste your own key from Step 1 in place of the placeholder.

    Model ID

    Start with this, change later
    circuit-2-turbo

    Under Custom Headers (or Headers), add one row:

    Header
    Authorization: Bearer cn_your_api_key_here

    Leave Context Length at TypingMind's default unless you know the model's window — the live catalog at GET /v1/models has current details. Click Test, then Add Model.

  4. Step 4

    Start chatting

    Pick your new custom model from TypingMind's model picker and start a conversation. Every message is billed against your CircuitNotion credit balance — top up any time on the Developer Platform.

Model IDs

Which model to type in

Use any of these as the Model ID, or switch models later by editing the custom model in TypingMind. The full, current list (with pricing) is always at the live catalog below.
