Clauselex vs Kvasir

Clauselex is a web workspace for legal professionals that brings matter documents, legal research, and drafting together. Users can add notices, agreements, judgments, and supporting papers to a matter and draw on them as context for research and drafting. Research can start with a plain-language question or a citation, with authorities and source links to explore. Deep Research supports more extensive investigations, and treatment analysis can explore subsequent decisions where supporting cases are available.

Drafting tools support working drafts, suggested edits, and saved-version comparisons; Word export is available on eligible plans. Shared matters let teams discuss work with comments and review workflows. Clauselex's bulk judgment data covers Indian Supreme Court and High Court decisions, while live search uses the Indian Kanoon API. The free tier includes one matter, five Deep Research runs in total, three monthly drafts without export, five monthly uploads, and seven-day history. Paid plans start at ₹999/user/mo. The service warns that AI may make mistakes and source coverage may be incomplete, so users should check facts, legal reasoning, current position, and relevant passages before relying on answers.

Kvasir combines a legal research app with a REST and MCP grounding API for German, Austrian, Swiss, and EU law. It reports coverage across nine jurisdictions, with over 450,000 norms and over 450,000 court decisions refreshed daily. The API supports legal search, citation resolution, batch verification, draft checking, legal objects, and citation relations; it can also check citation existence and compare draft quotations with canonical wording. Full draft text is transmitted only through check_draft, which requires the separately granted legal.check scope. MCP setup is documented for ChatGPT, Claude, Microsoft 365 Copilot, Perplexity, and Mistral Le Chat; developer guides cover Claude Code, Claude Desktop, Cursor, and VS Code. Plain REST access is also available. The free Hobby plan costs nothing and includes the app, an API key, MCP, and 2,000 sips per month. A keyless sandbox allows 20 requests per day; the MCP demo allows 10 tool calls per day and IP. Kvasir says requests are processed in memory, not stored, while aggregate usage counters are retained.
