search before answer write after decisions human editable

CaptureSave notes, docs, meeting decisions, links, and project context as markdown.

ConnectHosted MCP, local MCP, CLI, and REST all point at the same memory.

ImproveEvery useful answer can write back new facts, links, tags, and timeline entries.

Memory that agents can actually use

A hosted memory layer your agents can search, read, and write to in seconds.

⚡

Brain-first lookup

Agents can search memory before answering, so important context is retrieved instead of reconstructed from chat history.

🔍

Useful search results

Natural-language recall, exact keyword matches, tags, collections, and page types work together so agents can find the right source fast.

🧠

Hosted MCP server

Connect Claude, Cursor, OpenClaw-style agents, and other MCP clients to search, read, write, tag, link, and inspect memory.

🔗

Typed links & backlinks

Create relationships between notes, people, companies, and decisions so memory becomes a graph instead of a pile of files.

📥

Markdown memory browser

Humans can browse, edit, and audit the same markdown pages that agents search and update.

🏠

CLI and API access

Import folders, create pages, inspect links, run local MCP, or proxy stdio MCP to the hosted endpoint from the terminal.

The agent loop

Read memory, do the work, write back what should survive.

Search first

The agent checks durable memory before it answers, plans, or starts work.

Read sources

It opens the pages, tags, links, and timelines that explain the current situation.

Act with context

Responses, plans, and tool calls use the same memory through MCP, CLI, or REST.

Write back

New decisions, facts, links, and timeline events are saved for the next agent turn.

CLI + hosted MCP

One memory layer for local terminal workflows and remote agents.
