Terms of service

Last updated: October 6, 2026

These terms govern your use of Comment.io, the shared document workspace at comment.io, including its web app, SSH access, HTTP API and MCP servers (together, the “Service”). The Service is provided by Comment, Inc. (“we”, “us”). By using the Service you agree to these terms. If you use it for an organization, you agree on its behalf and confirm you may do so.

Accounts

You need an account to use the Service. Give us an email address you control and keep your sign-in methods secure. You are responsible for activity in your account. You must be at least 13 years old, and old enough to agree to these terms where you live.

Agents

The Service lets you approve AI agents to act in a workspace, by SSH key, OAuth grant (for example, an MCP client such as ChatGPT or Claude) or API token. An agent you approve acts with the access you gave it, and what it does is your responsibility as if you had done it. Approve only clients and agents you trust. You can disconnect an agent at any time in the workspace’s Settings, under Agents; what it changed before then stays in the workspace.

Your content

You keep all rights to the content you and your agents put in the Service. You grant us a worldwide, non-exclusive license to host, store, copy, process, transmit and display that content only as needed to provide and secure the Service and as you direct, for example when an agent you approved reads it. We never use your content to train AI models or for any other secondary purpose, never sell it, and never use it for advertising. Our privacy policy describes how we handle personal data.

You are responsible for your content and confirm that you have the rights needed to put it in the Service. Workspace members share the workspace’s content with each other and with its agents.

Acceptable use

Do not use the Service to:

• break the law or infringe anyone’s rights;
• store or share malware, or content that exploits or harms children;
• harass, threaten or defraud anyone, or send spam, including through invitations;
• access accounts, workspaces or data you are not authorized to access, or probe, scan or test the Service’s security without our written permission;
• overload or disrupt the Service, or circumvent its limits; or
• resell the Service or build a competing service from it.

We may remove content or suspend access that violates these terms. Where reasonable, we will tell you first.

Third-party services

The Service works with services we do not control, such as MCP clients, Google sign-in and the OpenAI-powered workspace assistant, which is on in new workspaces until an owner turns it off. Your use of them is governed by their own terms. When you connect one, content you or your agents send to it leaves the Service.

Changes to the Service and fees

The Service is under active development. We may add, change or remove features. The Service is currently free. If we introduce fees, we will tell you in advance, and paid features will not apply to you unless you agree to them.

Ending your use

You can stop using the Service at any time, and a workspace owner can delete a workspace from Settings. We may suspend or end your access if you violate these terms, if required by law, or if we discontinue the Service. If we discontinue the Service, we will give at least 30 days’ notice so you can export your content, unless that is not legally possible.

Disclaimers

The Service is provided “as is” and “as available”. To the extent the law allows, we disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose and non-infringement. We do not promise that the Service will be uninterrupted or error-free, or that agents will act correctly. Keep your own copies of important content.

Limitation of liability

To the extent the law allows, we will not be liable for indirect, incidental, special, consequential or punitive damages, or for lost profits, revenue or data, arising from your use of the Service. Our total liability for any claim relating to the Service is limited to the greater of the amount you paid us in the 12 months before the claim and US$100. Some jurisdictions do not allow these limits, so they may not apply to you.

Indemnity

If you use the Service for a business, you will defend and indemnify Comment, Inc. against third-party claims arising from your content, your agents’ actions or your violation of these terms.

Governing law

These terms are governed by the laws of the State of Washington, USA, without regard to conflict-of-law rules. Disputes will be resolved exclusively in the state and federal courts located in King County, Washington, and you and we consent to their jurisdiction, unless the law where you live gives you the right to bring them elsewhere.

Changes to these terms

We will post changes on this page and update the date above. If a change is material, we will tell you by email or in the Service before it takes effect. Continuing to use the Service after that means you accept the new terms.
