Terms of Service

Last updated: June 2026

By using Tellis, you agree to these terms.

What Tellis is

Tellis is a narrative architecture tool. It uses AI to help you find and build a story from your input. It is a thinking partner, not a source of fact. Do not rely on Tellis output for legal, financial, or medical decisions.

Your content

You own everything you input into Tellis. We do not claim any rights to your content. Your input is sent to Anthropic's API to generate output and is not stored by Tellis.

Acceptable use

Use Tellis for legitimate professional and creative purposes. Do not attempt to reverse-engineer the product, abuse the API, or use Tellis to generate harmful content.

Accounts and billing

Tellis offers a free trial with three narratives — no credit card required. After your trial, you may subscribe to a paid plan (Individual or Team) to continue using the product. Current plan details and pricing are shown on our website and at checkout when billing is available.

Paid subscriptions are billed in advance on a recurring basis (monthly or annually, depending on the plan you choose). By subscribing, you authorize us and our payment processor to charge your payment method at the start of each billing period until you cancel.

You may cancel your subscription at any time. Cancellation takes effect at the end of your current billing period — you will retain access until then. We do not provide prorated refunds for partial billing periods unless required by law.

Team plans require a minimum number of seats and may be offered on annual terms only. The account holder responsible for billing is responsible for all seats on the plan.

We may change plan features or pricing with reasonable notice. Price changes apply to the next billing cycle after notice is given. Continued use after a price change means you accept the new pricing.

No warranties

Tellis is provided as-is. We make no guarantees about uptime, output quality, or fitness for a particular purpose.

Changes

We may update these terms as the product evolves. Continued use means you accept the current terms.
