CourtListener vs Indian Kanoon

CourtListener is a web-based legal research service with a searchable archive covering opinions from U.S. federal and state courts, oral arguments, judges, judicial financial records, and federal filings. Its RECAP Archive includes nearly every federal case, hundreds of millions of docket entries, and tens of millions of legal documents. Search tools cover case law, dockets, and citations, and alerts can track topics, people, companies, citations, and other searches. Free Law Project also provides REST APIs, bulk data files, webhooks, database replication, and an MCP server through which AI assistants can access CourtListener data and APIs. The project is built on open source technology. The free non-member plan includes five docket alerts, unlimited daily opinion search alerts, five daily RECAP search alerts, five Pray & Pay requests, and API limits of 5 per minute, 50 per hour, and 125 per day. Paid tiers list higher limits. Complimentary EDU and qualifying LSO memberships are also available.

Indian Kanoon provides searchable access to Indian laws and court judgments, connecting statutes with cases to help readers locate relevant clauses and interpretations. Its database contains over 3 crore documents, including judgments, orders, laws, Lok Sabha debates, and Law Commission reports. Search filters include document type, date, title, citation, author, and bench, alongside phrase and Boolean-style operators. For documents longer than five paragraphs, structural analysis separates material such as facts, issues, arguments, reasoning, and conclusions. It also labels cited-case discussion by whether a party relied on it, a court accepted it, a court viewed it negatively, or the treatment is unclear. Prism AI offers legal questions grounded in the database, document chat, drafting and review, counterarguments, outcome predictions, moot simulation, and study assistance. NoteIK supports research topics, searchable notes, annotations, and collaboration. Daily alerts can identify matching additions or new orders citing a selected judgment. API access includes search and document endpoints, Python and Java clients, and JSON or XML responses. The service is available on web and Android, as well as through its API. Its free plan includes a limited number of Prism credits, 25 court copies per month, and two query alerts.
