Claude agents are faster

​

Platform improvements

​

Padding & margin UX

• Lots of comments polish based on early feedback and usage.

​

Comments

• You can now make more precise visual changes faster with comments. Think of it as a new way to share design feedback, but with the AI agent you’re collaborating with. We think this can help designers iterate faster across more problems at once.

​

More Claude models

• Persisted chat session and messages when you deselect an element, so you no longer lose your conversation context.
• Added download progress when downloading a new update.

​

Improvements to resizing elements

• Resizing feels more fluid now. You can drag from anywhere on the element to make the change.
• Added better error tracking with analytics from Sentry and Posthog to help us catch and fix issues before you hit them!

​

Community support

• Links in the platform for joining the Rivet discord from the help center in the desktop app.

​

Bug fixes
