Working with files, without the friction.

Everything you do a hundred times a day is one key or one drag away, on your disk and inside archives.

Up to four panes, each with tabs

Copy across with F5, move with F6, drag tabs between panes. Keep layouts you like as workspaces.

Claude Code and Codex, in the folder you are looking at.

The AI Agent area runs your agents next to the file list. Changes they make show up immediately, and sessions keep running when you hide the area.

The context menu of a document with Open in Claude Code, Open in Codex, Ask AI, Summarize with AI and Suggest Names with AI
Right-click any file or folder to start an agent there, summarise it or get name suggestions.
The Ask AI dialog with a question about a quarterly report
Ask AI sends your question with the selected files. The answer arrives in the console, ready for follow-ups.
The Automations window with a folder sync set to run every 60 minutes

Automations that check their own work.

  • Describe

    Say what should happen and when. Claude Code drafts a script and a separate check, and asks if something is missing.

  • Review

    Read the plan and both scripts, edit them, save. No AI runs after that.

  • Run and verify

    By hand, every few minutes, daily or at launch. A run only counts once the check passes.

The folder sync template needs no AI at all and verifies every file with SHA-256.

Let your agents see what you see.

Turn on the built-in MCP server and Claude Code, Codex or Cursor know the folder and files you have selected, and can browse, search and read.

Settings open on Keyboard shortcuts, with a key field for each command

Every shortcut

Click a command and press the keys. Up to four bindings each, and one button restores them all.

Seven sections, applied at once

General, appearance, icon sets, sound, files and search, AI and privacy, and shortcuts. Every open window follows instantly.

Private by default.

  • AI features start switched off

    Activity history, semantic search, the file assistant and the MCP server wait until you turn them on.

  • Models download on request

    Nothing is fetched until you press the button, and only pinned model versions.

  • Local models run offline

    Embeddings and the file assistant run on your machine, in their own worker.

  • Secrets stay in the keychain

    Server passwords, keys and sign-in tokens are stored encrypted by the system.

Your hands stay on the keyboard.
