About This License
The IDK-Strongleft License is a strong copyleft license functionally similar to the AGPL-3.0, designed for works created with AI assistance. It requires that derivative works be distributed under the same license and includes a network interaction clause requiring source disclosure for network-accessible deployments.
Copyleft Requirements
- Modified versions must use this license
- Source code must be provided
- Network deployments must offer source
- Downstream recipients get automatic license
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:
- Simultaneous AGPL-3.0 grant — simultaneously granted under AGPL-3.0; recipients may rely on either grant
- AGPL-3.0 compatibility — combinable with AGPL-3.0 works (the sole compatible external license)
IDK-Strongleft vs IDK-Weakleft: The key difference is the network interaction
clause. IDK-Strongleft (like AGPL) requires source disclosure when users interact over
a network. IDK-Weakleft (like GPL) does not.
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.
