What It Is

DMAS (Draw, Mark and Share) is a Chrome/Chromium browser extension for annotating web pages. Its core purpose is to let users highlight, draw, add comments directly on web pages, and share links to annotated pages with others. It covers use cases such as study notes, coworker feedback, remote assistance, web content proofreading, and presentation/reporting scenarios.

Core Features and Collaboration

The product offers simple annotation, auto-save, screenshots, link sharing, and real-time collaboration. Users can save notes locally, or register an account and sync them to the cloud so they can restore their annotations after switching devices or browsers. For collaboration, Pro users can create a shared drawing room where multiple users can draw and annotate on the same page in real time. Other participants do not necessarily need Pro, but they do need to register and log in to the extension. Recipients of shared links must also install the extension, which raises the barrier for external collaboration.

Pricing and Payments

DMAS uses a free tier plus Pro subscription model. The free version can be used offline without registration, but it limits the number of saved pages and shared links, and cannot create collaboration rooms. Once the limits are reached, new content will overwrite older content. Pro unlocks unlimited saved pages, unlimited shared links, real-time collaboration rooms, and priority technical support. The main text does not disclose specific pricing. Payments are handled via a Telegram bot using Telegram Stars; subscriptions do not auto-renew, and additional payment methods are planned for the future.

Security, Deployment, and Compatibility

DMAS states that it uses modern encryption methods, does not store personal information without consent, and does not share data with third parties. In terms of deployment, it is a combination of a browser extension and a cloud sync service, while also supporting offline local storage. No self-hosted option is provided. It currently supports Google Chrome and Chromium-based browsers, while support for Firefox and other browsers is only planned. Developer and enterprise capabilities such as APIs, webhooks, enterprise SSO, and audit logs are not disclosed.

Pros, Cons, and Who It’s For

Its strengths are that it is easy to get started with, focused in functionality, usable offline without registration, and includes real-time collaboration and screenshot export capabilities. Its drawbacks include unclear pricing, payment methods that may be inconvenient for users in some regions, and limited information on enterprise-grade permissions and compliance. It is better suited to individual learners, small teams, product/design feedback, and lightweight remote assistance. Enterprises that require strict permissions, auditing, compliance certifications, or deep integrations should evaluate it carefully.

Access from China and Alternatives

The main text does not provide information on access from mainland China, network connectivity, or local payment options, so the status is unknown. Because Pro payments depend on Telegram Stars, domestic users may face additional uncertainty around payments and account setup. Comparable alternatives include Hypothesis, MarkUp.io, Diigo, and Web Highlights, while tools such as 飞书 and 腾讯文档 can cover some annotation and collaboration needs.
