Frequently asked questions

What counts as an AI investigation?

Each time Whistlrr automatically investigates an alert — pulling logs from Datadog, errors from Sentry, metrics from CloudWatch, and recent commits from GitHub — that counts as one investigation. Manual triggers from the dashboard count too.

What does "Bring Your Own Key" (BYOK) mean?

Pro and Business customers can supply their own Anthropic API key. When you do, investigations draw from your own Anthropic quota — so there's no per-investigation charge at all. You just pay the flat monthly base fee. This is ideal for teams running many investigations per month.

How does the overage billing work?

Once you exceed your included investigations for the month, each additional investigation is billed at your plan rate via Stripe's metered billing. You see exactly what you'll be charged at the end of the month — no surprise bills.

When does the investigation count reset?

Counts reset at the start of each calendar month. Unused included investigations do not roll over.

Is there a discount for annual billing?

Yes — save 20% when you pay annually. Pro becomes $7.20/month ($86.40/year) and Business becomes $23.20/month ($278.40/year). Overage rates remain the same.

What payment methods do you accept?

All major credit cards (Visa, Mastercard, American Express) via Stripe. Annual plans can be invoiced on request.

Do you offer refunds?

Yes — 30-day money-back guarantee on all paid plans. No questions asked. Metered overage charges incurred during the period are non-refundable.
