What you give up either way

  • Proprietary generation quality and ongoing model improvements provided by the vendor
  • Contractual security, DPA/NDA and Trust Center assurances out of the box
  • Enterprise features such as team pipelines, high-volume throughput guarantees and SLA-backed support
  • Polished UX and built-in multi-office compliance testing/certification workflows

An open-source project doing the core job proves a replacement is possible. It does not prove it matches PatentFig, and it does not prove anyone has run it for a month. How we decide.
