Your second brain.
Notes that remember, agents that follow through.

Download View on GitHub

Sample data and simulated replies. No sign-in, no model calls.

A second brain that stays yours.

Your files stay yours.

Notes and projects are plain text files on your device, easy for agents to read and easy for you to keep. Turn on Forsion Cloud when you want sync across devices.

Agents that remember and follow through.

Each Tangu agent keeps its own long-term memory. Muse and Historian can work in the background to tidy memory, plan tasks and check off finished to-dos, within the time, permissions and budget you set.

Shape it your way.

Add spaces and plugins from the marketplace, arrange the layout, and build a workspace that fits how you think.

Many spaces, one desktop.

Switch spaces from the sidebar, or add new ones with plugins and layouts.
