Web

A notebook where each page can be a different tool, kept in nested sections and searchable in full.

journals.one GitHub

  • Write

    Quick notes, formatted documents and pages of movable text, media and code blocks, linked to each other with backlinks.

  • Organize

    Nested task lists, Kanban boards, spreadsheets with formulas, and tables with filters, computed columns, charts and scripts.

  • Create

    Draw.io and Excalidraw diagrams, a calculator notepad, and small apps you build in HTML, CSS and JavaScript, with AI to help.

  • Keep

    Every page's history with what changed, a recycle bin, and an MCP server so AI agents can read and edit your notebook.

Assist

A workspace for AI coding agents, in your browser or terminal. Run Assist's own agent, Claude Code, Codex and Antigravity side by side, with your project's files and Git beside them, on any of your computers.

  • Every agent in one place

    Assist's own agent, Claude Code, Codex and Antigravity as threads side by side, with the sign-ins you already have.

  • Your project beside the chat

    A file explorer, Git source control with diffs, and previews of HTML, Markdown and diagrams.

  • Across your computers

    Pair your other computers and work on any of them from one browser. Files, sign-ins and jobs stay where the work runs.

  • From your phone

    The web app works on a phone, with a key row for Esc, Tab, Ctrl and the arrows when you drive a terminal.

  • Big jobs in the background

    Workflows split a job across many agents running at once, and pick up again after a restart.

  • Remembers and schedules

    Past chats and facts you give it carry into new ones, and tasks run at a set time, on a file change or on a webhook.

File Organizer

Windows 11

Find your files by tags instead of remembering their names and folders.

  • Tag a folder and everything inside it has the tag, including files added later
  • Tags stay with a file when it's renamed, moved or saved over
  • Suggests tags from the ones you use, or from an optional AI pass
