In their own words

Case Calendar

Case Calendar is an open-source Python command-line tool that turns federal court docket information from CourtListener into calendar feeds for hearings and filing deadlines. It creates an ICS feed per case for subscription in calendar apps that support iCalendar, and can send events one way to Google Calendar or Microsoft 365 or Outlook after a one-time OAuth setup. Its deadline tracking sends items classified as major to subscriber calendars while keeping procedural filings in an audit trail. Optional AI summaries use primary documents and dispositions, link action phrases to court documents and refresh when certain documents or event statuses change. Events retain the court’s timezone, including across daylight-saving changes. A real-time webhook can accept CourtListener updates and bypass the daily polling quota. The generated static index can be hosted behind an HTTP server. Hosted AI options include Anthropic, Google Gemini and OpenAI; local Ollama models avoid per-token API costs and keep docket text and PDFs on the host, according to the documentation. Use may incur LLM API costs and CourtListener quota limits. The project warns that docket data can lag and date extraction can miss or misread dates; it is not a replacement for attorney calendaring software.

Deadline Engine

Deadline Engine is a web tool for calculating court and procedural deadlines. It displays the governing citation and the steps behind each calculation, drawing on a catalog that the homepage says contains 4,871 rules across 20 jurisdictions. Its deterministic rule logic accounts for deemed service, applicable clear-day rules, business-day adjustments, official bank holidays and court office closures; it does not use AI to calculate deadlines. The free calculator requires no account. Users can export matters as CSV or JSON, with PDF and calendar exports available per matter. Professional keeps histories of eligible server-recomputed calculations on individual matters and adds calendar feeds and downloadable ICS files. The service does not determine jurisdiction, interpret evidence, read court orders or decide whether a rule applies to a case. Deadline Engine describes its output as procedural information, not legal advice, and says dates should be checked against rules and case facts. It is developed for individual legal professionals, including solicitors, barristers, paralegals and compliance professionals.
