Chandler is an open source Note-to-Self Organizer. It features calendaring, task and note management and consists of a desktop application, web application and a free sharing and back-up service called Chandler Hub.
Our goal is to serve the way people actually work, independently and together, particularly in small groups, a market segment we believe is underserved. Our belief is that personal and collaborative information work is by nature iterative and that the existing binary Done/Not-Done, Read/Unread, Flagged/Unflagged paradigm in productivity software poorly accommodates the reality of how people work.

We are also committed to breaking down technological barriers that prevent effective collaboration. Chandler Desktop and Chandler Server are cross-platform and standards-based because we realize that collaboration can't and shouldn't be trapped within a single system. Chandler Server provides web access to shared information that makes it easy for collaborators to hook into Chandler workflows without having to download the Desktop application.

Chandler attempts to build workflows that cut across and converge public collaboration and private communication as well as build a sharing model tailored to the informal, more intimate social dynamics of small groups.

We realized that the majority of the significant emails we send are sent while still in a draft-state: Lists that are incomplete, write-ups that await several rounds of heavy editing and half-baked proposals. As a result, email in Chandler is designed to function more more like sharing. Address items and send them via email. In Chandler sender and recipients can edit Sent messages and send them again as Updates. Repeat as necessary.

Chandler's collaboration workflows are built around small group social dynamics. Unlike corporations and institutions, small organizations often can't and won't dictate what software people use. Individuals in small groups also have stronger trust relationships which make most enterprise-scale security models feel cumbersome and an obstacle to using the software.


Superb and rather powerful calendar that's designed to allow users to share their information with other users
