About This License

The IDK-Weakleft License is a copyleft license functionally similar to the GPL-3.0, designed for works created with AI assistance. It requires that derivative works be distributed under the same license with source code, but does not include a network interaction clause.

Copyleft Requirements

  • Modified versions must use this license
  • Source code must be provided with binaries
  • Downstream recipients get automatic license
  • No network clause (SaaS does not trigger source disclosure)

AI-Specific Features

  • AI authorship uncertainty acknowledged
  • Copyleft as contractual covenant (survives even if copyright fails)
  • Patent non-assertion + grant
  • Trade secret risk acknowledgment

Additional features:

  • 7 fallback copyleft licenses — simultaneously granted under AGPL-3.0, GPL-3.0, LGPL-3.0, MPL-2.0, EPL-2.0, EUPL-1.2, and IDK-Strongleft
  • Expanded compatibility — combinable with AGPL-3.0, GPL-3.0, LGPL-3.0, MPL-2.0, EPL-2.0, EUPL-1.2, and IDK-Strongleft
IDK-Weakleft vs IDK-Strongleft: IDK-Weakleft (like GPL) does not require source disclosure for network deployments. If you want the stronger AGPL-like protection that covers SaaS usage, use IDK-Strongleft instead.
Important: This license was drafted with AI assistance. It has not been reviewed by a licensed attorney. There is no warranty that it works as intended. This is not legal advice.
