One brain,
every agent.

Markdump is a markdown library your AI assistants share. Claude, ChatGPT, and whatever you use next all read and write the same notes. And because it’s just a folder of files, you can open it yourself anytime.

100 MB free·every change versioned·they’re your files

Your assistants forget. And each one remembers alone.

Close the chat and the context is gone. Move from Claude to ChatGPT and you start over. Markdump gives them one shared memory that sticks around: a knowledge base any agent can read, search, and update, instead of a dozen disconnected ones.

One library, many jobs

Whatever your agents touch can live here as plain files you can open too.

notes/

Personal second brain

Notes, ideas, and bookmarks in one place every assistant can reach and update.

projects/spec.md

Project memory across tools

Specs, decisions, and TODOs that Claude writes and Cursor or Codex read. No copy-paste between tools.

runbooks/deploy.md

Team runbooks & docs

Ops runbooks and how-tos your agents keep current and query on demand.

research/

Research & reading notes

Capture sources and summaries, then ask any assistant to synthesize across them.

New to MCP? It’s the standard way assistants connect to outside tools, like a USB port for your AI.

Ask it to save a note

Then open your library and watch the file appear. Your agent just wrote to your folder, and the next one can read it.

A real knowledge base, not a chat history

Shared across agents

Connect any MCP client. They all work the same library, so what one writes, the next one reads.

Searchable by anything

Full-text grep, glob find, and semantic search across everything, for your agents and for you.

Edited with precision

Agents make surgical changes (insert, replace, substitute) instead of rewriting whole files. Every write is versioned.

Structure your agents understand

Markdump speaks OKF, the Open Knowledge Format: a light convention that turns a folder of notes into a map your agents can navigate. A few lines of frontmatter say what each file is and how it connects, so an assistant finds the right note and keeps it current instead of guessing. New agents learn the format the moment they connect.

  • +

    Discoverable. Every file declares its type and a one-line summary, so search and agents surface the right thing.

  • +

    Connected. Cross-links spell out how concepts relate, so an agent can follow the thread.

  • +

    Self-describing. Reserved index.md maps and a log.md history give a table of contents and a paper trail.

Questions, answered

What is Markdump?

Markdump is a markdown library your AI assistants share. Claude, ChatGPT, and any MCP client can read, search, and write the same notes, and because it's just a folder of files, you can open and edit it yourself anytime.

Which AI assistants does Markdump work with?

Any client that supports MCP (the Model Context Protocol), including Claude, Claude Code, ChatGPT, Codex, and Cursor. They all connect to the same library, so what one assistant writes, the next one can read.

What is MCP?

MCP (Model Context Protocol) is the standard way AI assistants connect to outside tools and data, like a USB port for your AI. Markdump exposes your file library to assistants over MCP.

How do I connect my AI assistant to Markdump?

Sign in with your email, then add your Markdump MCP endpoint (https://markdump.com/mcp) as a connector in your assistant. Then ask it to read or save a note and watch the file appear in your library.

Is Markdump free?

Yes. You get 100 MB of storage free to start, and every change is versioned.

Do I own my files?

Yes. Markdump stores plain .md files in folders with no proprietary format and no lock-in. You can browse, edit, or export everything anytime. Deletes are recoverable and every overwrite keeps a previous version.
