How it works
In Default mode, your Transmuter subscription includes everything — platform access and AI processing. The subscription price is higher because it covers the cost of AI usage. In BYOK mode, you provide your own API key from Anthropic. You pay Anthropic directly for AI usage, and your Transmuter subscription is lower because it only covers the platform.| Default Mode | BYOK Mode | |
|---|---|---|
| Starter plan | $69/month | $29/month |
| Pro plan | $149/month | $59/month |
| AI costs | Included in subscription | Paid directly to Anthropic |
| AI token limit | Plan-based (500K-2M) | Your Anthropic account limit |
| Setup | Nothing extra | Add your API key in settings |
Who is BYOK for?
BYOK mode is ideal if you:- Already have an Anthropic account with API access
- Want to control and monitor AI costs directly
- Run many Plan Casts and want to optimize costs
- Prefer to keep AI usage separate from platform costs
Setting up BYOK
Get an Anthropic API key
If you do not have one, visit console.anthropic.com, create an account, and generate an API key.
Switch to BYOK mode
In Transmuter, go to Settings > Billing and select BYOK mode. The switch takes effect at the start of your next billing period.
Cost comparison
A typical medium-complexity Plan Cast uses approximately $18-25 of AI tokens at Anthropic’s rates. Here is how costs compare over a month:| Scenario | Default (Pro) | BYOK (Pro) + Anthropic |
|---|---|---|
| 2 Plan Casts/month | $149 | $59 + ~$40 = ~$99 |
| 5 Plan Casts/month | $149 + add-ons | $59 + ~$100 = ~$159 |
| 10 Plan Casts/month | $149 + add-ons | $59 + ~$200 = ~$259 |
Actual AI costs depend on the complexity of your business plan and the resulting product. The figures above are estimates for medium-complexity products.
