Terms of use

Last updated 10 November 2026. These terms cover the free, invite-only Alpha.

The Alpha

Whetstn is free while it's in Alpha, and it's still being built. Things will change, and some may break. We may pause or end the Alpha, or an invitation, at any time, and we'll give you a chance to download your work first wherever we can. A paid plan will come later. You'll be told before anything costs money, and nothing will be charged without your agreement.

What Whetstn is, and isn't

Whetstn helps you think a strategy through, test it and challenge it. Its scores, verdicts, research and AI output are aids to your own judgement. They aren't financial, legal, accounting or other professional advice, and they can be wrong: AI can state things that aren't true. Check anything important before you rely on it, and take professional advice on decisions that need it.

Your work is yours

You own what you put into Whetstn and what you make with it. We don't claim any rights in your strategies. We use them only to run Whetstn for you, as the privacy page explains.

Your Anthropic key

The AI steps use your own Anthropic API key. Anthropic bills you directly for what you use, under your agreement with them. Keep your key private, and consider giving it a spending limit in Anthropic's console.

Fair use

Please don't use Whetstn to break the law or anyone's rights, to upload material you're not allowed to share, to attack or overload the service, or to try to reach anyone else's data. We may end access for anyone who does.

Our responsibility

We provide the Alpha free and as it is. As far as the law allows, we aren't liable for losses arising from using it or relying on it. Nothing in these terms takes away rights you have under the Australian Consumer Law that can't be excluded.

Law

These terms are governed by the law of New South Wales, Australia.

Changes and contact

If these terms change in a way that matters, we'll email people on the list before the change takes effect. Questions go to hello@whetstn.com.
