Alto

A connector for Claude Desktop · v1.4.0

Alto interviews you about material you already have — a course, a novel, a research project — and builds it into an interactive, filterable timeline. Cards on colored act bands, entity chips, connection lines, detail pages using your own headings, highlights and notes, a mobile layout, and a single offline file you can send to anyone.

It never invents content. Alto organizes what you give it and nothing else — sparse notes make a sparse timeline, on purpose.

Download

macOS Apple Silicon — M1 and later 48 MB macOS Intel 52 MB Windows 64-bit 59 MB

Installing

  1. Download the file for your computer.
  2. Open Claude Desktop → Settings → Extensions → Advanced settings → Install Extension… and choose the file you downloaded. (Double-clicking it works too, if your system opens .mcpb files with Claude.)
  3. Restart Claude Desktop. Alto appears under Extensions.
  4. Start a chat and say “I want to build a timeline in Alto — interview me.”
Do I need to install anything else?

No. Each download carries its own copy of Python, so there is nothing to set up first. That is why the files are around 50 MB.

Where do my timelines go?

Onto your own computer, in ~/Documents/Alto. Every timeline is also produced as a self-contained file you can open or send to someone without any server involved.

Publishing shareable web links is optional and uses your free Firebase project, never one of ours. Leave it unconfigured and Alto simply stays offline. See the privacy note.
