How to publish a Gemini canvas at an address you own
Canvas built the page in a panel next to the chat, and it exports to Docs, Slides, PDF or Colab, none of them a site. Connect Birta once and Gemini publishes the canvas itself at an address you own: your domain, your choice of who opens it, the same link after every edit.

What Gemini gives you today
Canvas: a panel beside the chat
Choose Canvas under the prompt box and Gemini builds docs, apps, slides, code or web pages there. Export copies the contents or sends them to Docs, Slides, PDF or Colab; no HTML file to download.
Share: a snapshot, not a site
Share & export gives a g.co/gemini/share link that keeps the canvas as it was when you made the link. To show a newer version you make a new link.
Connect Gemini to Birta once
Give Gemini a place to publish the canvas it already has.

Sign in once
The first time Gemini uses Birta, a browser tab asks you to sign in — with a one-time code from your email or with Google. No key to copy.
Then ask Gemini to publish
Copy this into the conversation where Gemini made your canvas.
Publish the canvas that is open in this conversation as a site on Birta. Create a project named "Pricing calculator", put it into index.html with its CSS and JavaScript, publish it, and give me the live link. If anything in it needs Gemini to run, tell me what will change first.
- published, version 1
- here is the live link: pricing-calculator.birta.link
Share it. Keep making it better.
Tell Gemini what to change. It publishes again to the same address.
Same URL after edits
Each change is a new version on the same address. Every version is kept, rollback is one step.
Only certain people
Close version links to everyone but the people you add. They sign in and leave remarks on the page.
A few good questions
Give your canvas an address.
