What is a bubble? Context you save once and use in any AI app
A bubble is anything you want your AI to keep and use. You save it once, and ChatGPT, Claude, Gemini, Grok, Perplexity, Cursor and 20+ more AI tools can read it.

What goes in a bubble
If an AI can read it and act on it, it can be a bubble.
| Kind | For example |
|---|---|
| A memory | How you like answers written, your job, the facts you keep repeating |
| A project brief | The stack, the conventions, and what's off limits |
| A skill | How to do something, step by step |
| An agent | A role, its instructions and the tools it uses |
| A workflow | A weekly report your AI should do the same way every time |
| A saved chat | The long conversation where you settled the pricing |
A bubble is Markdown text, up to 512 KB. Here's a skill as a bubble:
# Review a pull request
1. Read the description and the linked issue first.
2. Run the tests before reading the code.
3. List problems by severity: bugs, then security, then style.
4. Say what you didn't check.How you use one
Connect your AI app once. Paste this line into ChatGPT, Claude, Gemini, Grok, Perplexity, Cursor or whichever AI you use:
Connect my Sixteen Bridges account — follow https://sixteenbridges.com/llms.txtChat apps tell you the steps. Claude Code, Cursor's agent and other tools that run commands do the sign-in themselves, and you click Allow. Some apps only allow connectors on paid plans, and the steps for each app say which.
Then you talk to your AI as usual:
- “Save this as a bubble.”
- “Read my bubble about the pricing page and continue from there.”
- “Add to my project brief: we moved to Drizzle.”
Change a bubble once, and every app gets the new version the next time it opens it. You can also paste text or upload a Markdown file on your bubbles page, or use the sixteenbridges command from a terminal.
What you control
- Nothing is saved on its own. A bubble exists because you or your AI asked for it, and you can read every word of it.
- Group bubbles into buckets, and share a copy with a colleague by email.
- Disconnect any app on your account page. Its access ends within a minute.
- A deleted bubble stays in your trash for 7 days, so you can bring it back.
- We don't train AI models on your bubbles.
