Agents do your content ops.
You supervise.

LeftFold connects AI agents to your content. They summarize, extract entities, generate structured data, and suggest links. You review everything in the mailbox.

Describe your business

Tell LeftFold about your content model. Event storming proposes custom content types fitted to your domain. No configuration files, no schemas to write.

Agents enrich automatically

When you create content via MCP, API, or CLI, agents summarize, extract entities, generate structured data, and suggest cross-links — all within your brand guardrails.

Review in the mailbox

Every enrichment lands in your mailbox. Approve, edit, or reject with one click. Your approval builds the dataset that makes agents smarter over time.

Append. Fold. Query.

Three concepts that give your content a structured, auditable history that grows with every interaction.

01

Append

Events flow in naturally

Content enters through MCP clients, the API, or agent enrichment. Each change is recorded as an immutable, typed event. "Published an article" becomes article.published with structured data. Nothing is lost, nothing is overwritten.

02

Fold

Events become current state

When you need the current state, the system 'folds' the event history — replaying events in order, merging changes. Five events become one clean document. The fold is computed on demand and cached. Always fresh, never stale.

Query

Ask anything about your content

Every surface — dashboard, MCP tools, API, SDK — uses the same query pipeline. Fold events, join across types, group, sort. Results are cached and auto-invalidated when new events arrive.
