About Pastel

Feedback placed directly on a live website

Pastel gives designers, developers, agencies and marketing teams one place for feedback. Commenters mark up a live website, a PDF, an image or a video, rather than screenshots sent by email, and the company says the feedback stays in one organized place. Comments are layered on the real page through a proxy, so nothing needs to be copied or rebuilt for review. Pastel accepts any type of website and works with any web framework, the company says.

Guest access and approval records

Anyone with a shared link can review a canvas as a guest without creating an account. Guests can leave comments and replies, while team members with accounts can create and edit canvases and export comments. Approvals are recorded with an audit trail, so a team can show that each stakeholder has had their say before a campaign goes live.

Organizing feedback with statuses and deadlines

Work statuses, tags, mentions and deadlines keep feedback moving. Teams can see what has been done, what is still open and who is responsible for it, and deadlines can be set so that feedback arrives on time. Comments can be resolved one by one until the review reaches an empty inbox. Responsive testing shows how a design looks across different screen sizes, and copy can be edited in real time.

Connections to project tools and AI agents

Feedback can be turned into tasks in a project management tool, so projects keep moving without an extra step. The company has added an MCP server, which lets AI agents such as coding assistants act on comments on the team's behalf. The company says it has handled more than eight million comments.
