How signup works.

kotobase uses passwordless identity: a WebAuthn passkey for people, or a self-custodied Web3/DID key presented as a single-use CACAO through auth.kotoba.cloud. The wallet's recovery phrase signs you in without the wallet. Click Empieza gratis to sign in or create your identity, then choose Free hosted secure storage or a paid plan scoped to your tenant DID.

1. Create your identity

Use a passkey, your own Ethereum wallet, or its recovery phrase at auth.kotoba.cloud. No password, no email, no company SSO.

2. Choose a plan

Free is $0 and needs no card. Starter is $25/month (charged as ¥3,750) and Professional is $132/month (charged as ¥19,800); both open a tenant-scoped Stripe checkout. Business Critical ($292) is quoted by sales. Enterprise is a dedicated-deployment contract.

Business Critical — contact sales Enterprise — contact sales

3. Continue Free start

After you sign in on Free hosted secure storage, follow the continuous Free loop: biscuit, write, query, then pin. No founder step.
