Capabilities
Everything your calendar needs to keep matters on schedule
One calendar for every matter
Keep hearings, filings, depositions, and client meetings in a single calendar view, organized by matter so nothing is scattered across inboxes and sticky notes.
Dates linked to documents
Connect each calendar entry to the pleadings, motions, and correspondence it relates to, so the right document is one click from the date on your schedule.
Works with the tools you use
Integrates with Microsoft Word, Outlook, Google Docs, Google Drive, Dropbox, and Clio, so your team keeps drafting, emailing, and storing files where they already do.
Timesheet entries from your activity
OpenCase proposes timesheet entries automatically from your email and calendar activity, so billable work is captured as it happens instead of reconstructed later.
Shared visibility across the team
Attorneys and staff see the same schedule for each matter, so responsibilities and upcoming dates are clear without a round of status emails.
Reminders that reach you in time
Set reminders on the dates that matter and receive them ahead of time, so preparation starts early rather than the day something is due.
Outcomes
What a connected calendar changes
The mechanism is the same throughout: dates, documents, and billable time live together instead of in separate systems.
Fewer things slip
A single calendar with reminders means hearings, filings, and commitments stay visible instead of getting lost between tools.
Less time on manual entry
Automatic timesheet proposals and document links cut the routine copying and re-keying that eats into billable hours.
Context on every date
Because each entry links to its matter and documents, the background for any hearing or deadline is right there when you open it.
A schedule the whole team trusts
Shared visibility keeps everyone working from the same dates, so coordination happens in the calendar rather than in scattered messages.
Use cases
How legal teams use it day to day
Managing litigation schedules
Track hearing dates, filing deadlines, and trial dates across active matters in one place, with reminders so preparation starts well before anything is due.
Coordinating client meetings
Schedule consultations, depositions, and calls next to internal dates, so external commitments and matter work show up in the same unified view.
Keeping billable time accurate
Let calendar and email activity surface timesheet entries as work happens, so meetings and calls are captured instead of forgotten at month end.
Planning across the team
See where dates cluster for attorneys and staff, so busy stretches are visible early and work can be balanced before it becomes a crunch.
