Use your own Grok key

xAI's models — tuned for current events and candid takes. Bring your own xAI API key and every brief and chat runs on it — unlimited, on your quota, with the model you choose.

  1. 1

    Create an xAI account

    Go to console.x.ai and sign up (an X/Twitter login works).

    console.x.ai
  2. 2

    Add credits

    Open the billing section of the console and add prepaid credits — usage is pay-as-you-go.

  3. 3

    Create your API key

    API keys → create a key. Copy it immediately — it starts with xai-.

  4. 4

    Add it to RedditAsk

    Paste the key in the form on this page (or Model Settings inside the app), pick a model, and save. We validate it live before storing it encrypted.

Add your Grok key

Right here — no need to go back to the app. It lands in the same encrypted store as Model Settings.

Your keys follow your Reddit account

Connect your Reddit account first (read-only) — your API keys are then stored encrypted against it, work from any device, and unlock unlimited briefs & chat.

Key questions

Where is my key stored?

Encrypted at rest in our database, tied to your Reddit account. Keys are write-only: never shown again in full, never logged, never placed in URLs, never returned by the API — you only ever see a masked hint.

What does adding a key unlock?

All briefs and chat run on your own provider quota instead of RedditAsk's included AI — the daily caps disappear entirely, and you choose exactly which model does the analysis.

Can I remove it later?

Any time, from Model Settings or the account menu — removal is immediate. If you have another saved key it takes over; otherwise you fall back to the included AI with daily limits.
