Bring Your Own Claude Account vs API Keys: What's the Difference?

Yasmine never resells AI. Instead, you plug in the model access you already have — and there are two shapes of that: a Claude subscription (the monthly plan you might already pay for) or API keys (metered, pay-per-token, from OpenAI, Google, or Anthropic). People mix these up constantly. Here's the difference in plain terms.

The two options, side by side

Whose terms cover your dataAnthropic's — your accountYour provider's — your account

If you already pay for Claude, start there

Connecting your existing Claude subscription means zero new AI spend: Yasmine works inside the plan you already have, and your usage limits reset on your provider's schedule like always. If your team's limits mostly go unused each week, this is free capacity you're already paying for — put it to work.

When API keys make more sense

Volume: heavy daily use can outgrow a subscription's limits; metered keys never queue.
Model mixing: keys let you run different models in different channels — Gemini in #research, Claude in #eng.
Cost tracking: a dedicated key gives finance a clean, per-token line item.

Either way, three things stay true

  1. No resale. We never mark up tokens or sit in your billing path — you pay your provider directly.
  2. Your data, your terms. Conversations flow to your account, covered by your provider's terms. We never access it.
  3. Switchable. Start on your Claude account today, add keys later — or the reverse. Two-minute change either way.
Connect whichever you have — you're live in 2 minutes. Free 7-day trial, no card.
