Create Your First Capsule
Save your first piece of context to Horatius.
Via MCP (AI Conversation)
The easiest way to create a capsule is directly from an AI conversation. Just ask:
"Save this as a Solution in Horatius"
Your AI assistant will use the MCP tools to create the capsule, applying the type's guidance to structure the content appropriately.
Via the Web UI
- Navigate to your Library at /library
- Click New Capsule
- Select a Type (or create a new one)
- Write your content using Markdown
- Save
Understanding References
Every capsule gets a reference ID scoped to its type and your account. For example, if you create a capsule under the "Docker" type, it might get the reference @docker/1.
You can use these references in other capsules to compose rich context:
I solved a similar problem in @docker/1, but this time the issue was
with volume permissions rather than networking.What to Save
Good candidates for capsules:
- Solutions: Fixes to problems you might encounter again
- Decisions: Technical decisions with reasoning and trade-offs
- Prompts: Reusable AI instructions you want to run repeatedly
- Snippets: Code patterns you use across projects
- Processes: Step-by-step workflows for recurring tasks
