Vault
Your markdown vault, navigable
Point Marvinz at any local folder — the agent reads and writes the files in place. Browse them in a tree with folders and drag-and-drop, where links rewrite themselves when you move things.
Where AI output
becomes knowledge
you can navigate.
The visual workspace for Claude Code & Codex. Point it at your markdown vault and read, validate, and restore what the agent writes.

01 · How it works
One product, not two.
Marvinz makes the DIY stack of “Claude Code / Codex CLI + Obsidian” one product. The agent edits your local markdown directly inside a workspace where you read, navigate and curate — every change snapshotted, every tool call approvable.

02 · Features
The workspace native to the Claude Code / Codex + vault workflow.
Built for engineers and PMs who already run Claude Code or Codex alongside a markdown vault and want to read, navigate and validate what the AI generates — to trust it and build on it, instead of losing it in a terminal scroll.
Agent
Claude Code & Codex, right beside your files
Run Claude Code or Codex in a terminal scoped to your vault and watch its edits land in the editor in real time — the agent works on the same files you're reading.
Preview
Write markdown, watch it render
A live, rendered view of every note — headings, tables, task lists, code blocks, [[wikilinks]] and embedded images, all resolved as you read.
Search
Jump to anything
Open the command palette to fuzzy-find any file, or search the full text of your vault — then jump straight to the matching line.
Context
Send a selection to the agent
Highlight a passage in any note and hand it to the agent as context — no copy-paste, no leaving the workspace.
Snapshots
Every turn, reversible
Marvinz snapshots the files the agent touches on every turn. Restore any earlier version in one click — nothing the agent writes is ever lost.
