Problem

You’re building things faster than you can get them approved

Illustration of a web interface showing a prompt to build a landing page and a sample landing page featuring a beige athletic shoe on a stone surface with the slogan 'Run Further.'
Building used to be the bottleneck. Now your agent can build it in 5 minutes.
Graphic showing inputs from various communication apps—Email with 'Make the headline bigger', Team Chat with 'Make the blue darker', Text with 'Add logo', and Comments with 'Move CTA up'—being combined into an AI Prompt interface listing: 'Make the headline bigger', 'Change the blue to be darker', and 'Move CTA up'. A cursor drags 'Move CTA up' into the AI prompt input box.
But you’re still waiting for days on feedback. Then you have to manually prompt your agent.
How it works

“Now I can go as fast as my agent.”

Step 1
Connect your agent
Connect Pastel to your agent in seconds and upload what you built with one command.
Step 2
Share the link
Send a shareable link to your team, manager, or client. They open it and comment in context. No account needed.
Step 3
Action feedback
Ask your agent to triage the feedback or action it directly. It gets all the context it needs and uploads a new version when it's ready.

Works with what your agent can build

Your agent likes to build in HTML. Pastel can handle that.

Your questions, answered

Do reviewers need an account?
No, anyone can comment and leave feedback without an account. Just share a link to the Pastel canvas to get started.
Do I need to host or deploy my website first?
No, your agent can upload it directly to Pastel. You then get a link you can share with anyone for feedback that your agent will be able to read and act on. If you already host your website somewhere, you can also use Pastel with the live site - just paste in the URL when creating a canvas.
How does Pastel connect to my agent?
Pastel can connect to your agent either using our MCP server or our CLI tool. The best option to use depends on your agent. You can learn more here or just share that link and ask your agent for help setting it up.
Who can see what I upload?
You’re in complete control of who sees what you upload. Pastel canvases are visible to anyone with the link by default. However, you can password protect your canvases or set them to be visible only by your team or even only to you.
What files can I upload?
Pastel supports most things your agent can build. You can upload landing pages and other HTML content, images, videos, PDFs, and marketing emails. You can also use Pastel with live websites.
Which AI agents does Pastel work with?
Pastel works most agents, including Claude, ChatGPT, Codex, Cursor, Replit, and more. As long as your agent supports MCP servers or has access to a CLI, you can use Pastel. You can learn more here or just share that link and ask your agent for help setting it up.
Does my agent change things without me?
No, you always need to ask your agent to action feedback in order for it to do anything. Depending on your agent’s permissions, it may ask before taking any actions, but Pastel will never prompt your agent to do anything without your input.
