You built something clever with Cursor or Claude. Will it survive a patent examiner? Patent PreCheck is a free, keyless patentability read on your code in about 60 seconds: USPTO pillar scores (eligibility, novelty, nonobviousness), prior art matches, and the pillar holding you back. Web app, hosted MCP at patentprecheck.com/mcp, or npx in CI. Triage before counsel. Not legal advice.
