A knowledge base built for AI

Symbol organises what you know into capsules: small, focused, structured pieces of knowledge. Each capsule belongs to a type, which carries guidance that tells AI how to interpret and use it.

Reference any capsule by name — @my-business/1, @clients/4, @writing-style/2 — and it loads exactly. No search, no guesswork.

Works in any MCP-compatible AI tool. The same capsule, the same result, regardless of which AI you are working in.

How it works

Three ideas.
One workflow.

Symbol gives your knowledge a structure that AI can actually use. Not a pile of unstructured text to search through.

01

Create a Type

A type is a category with a purpose. You write guidance: instructions that tell AI how to handle everything inside it. @client-briefs, @debug-fixes, @recipes, anything.

02

Save Capsules

Each capsule is a unit of knowledge: a fix, a brief, a decision, a reference. Captured once, with a short ref like @wordpress-fixes/7, retrievable forever.

03

Inject into AI

Type @client-briefs in any AI tool connected via MCP and all your capsules load instantly as context. Your AI knows what you know, without copy-pasting.

Types & Guidance

Structure that
teaches AI

Write guidance once
Guidance tells AI how to interpret capsules in a type: their structure, tone, and purpose. Write it once and every capsule benefits.
@slug context injection
Every type has a short slug. Type @career in Claude, your MCP client, or any tool to inject all capsules from that type as context.
Share types with teams
Grant team members access to specific types. Everyone works from the same shared knowledge base, but access stays controlled.
Your types
Career@career6 capsules

Upcoming trips, destination notes, packing preferences, and travel style. Load when planning itineraries or booking accommodation.
Book Notes@book-notes11 capsules
Key takeaways, quotes, and personal reflections from books. Reference when writing, researching, or building on an idea.
