Overview

Muddy is a chat-like web browser (built on Chromium). Teams use Muddy to work with their teammates and software all in one window.

Muddy consists of Spaces: project, event, or competency based feeds in which users can send updates that consist of basic multimedia messages, specific files from applications (Google Doc, Airtable Base, Figma File, +anything web based), and annotations on both.

Recipients can then use those apps right in line of the messages to take the requested action or give the solicited feedback (review my design, update the CRM, approve the PR, confirm PTO in Gusto, etc).

Source-based assessment · automated evidence rules

Maturity is an evidence-based assessment, not a success rating. It may understate the current stage where evidence is limited. Coverage records documented areas, not a complete or independently audited company history.
