CaseCite is a self-hosted legal research and document-analysis platform designed for firms that want to keep their document corpus and application data on their own infrastructure. It combines eight tools around one shared knowledge base: question-answering over firm documents with source citations; document uploads and cloud-storage integrations; contract review, comparison, and redlining; drafting grounded in selected references; chat with CourtListener opinions; citation mapping; judge analytics; and case-law lookup tools. A user-defined practice profile supplies context across reviews and drafts. Long-document drafting uses a section plan and separate drafting windows before reconciling the result. The project emphasizes that AI outputs need verification and that its citation check is not a substitute for commercial citators such as Shepard’s or KeyCite.

The repository provides Docker-based deployment instructions and lets firms configure their own AI provider keys, including OpenAI, Anthropic, or Gemini for language tasks. Documents, indexes, chat history, and analyses remain on the deployment, but using AI sends relevant text to the configured providers; uploads also send text to an embeddings provider, while case-law searches go to CourtListener. Fully local processing requires self-hosted chat and embedding models. Uploaded documents and API keys receive application-layer encryption, but derived text such as vector chunks and chat history is stored unencrypted, making host-level disk encryption the operator’s responsibility. CaseCite is source-available under the Elastic License 2.0: internal self-hosting and modification are permitted, but offering it as a hosted service is not.
