Save context. Reference it anywhere.
Problem
Repeating yourself.
Symbol
Context by reference.

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

Structure that
teaches AI
@career in Claude, your MCP client, or any tool to inject all capsules from that type as context.Built for people who
work with AI daily
Every project brief, one reference away.
Alex references @projects and the AI has the full scope, budget, goals, and timeline. No more copy-pasting the brief into every conversation.
Audience, voice, and strategy. Always loaded.
Personas, content pillars, brand tone, and publishing rules all live in one type. Sam loads it once and every draft lands on-brand without a briefing doc.
Team knowledge that doesn't leave with people.
Processes, decisions, and shared context all saved as capsules. New team members load the type and hit the ground running. No lengthy handover docs needed.
